A Tree Spacing Calculator that will calculate the number of trees per acre and spacing between trees and tree rows. ), amaranth (Amaranthus cruentus L.), cocks comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). The use of plant population calculator is a pre-planting operation. COMPARISON OF PLANT POPULATION BY PHYSICAL COUNTING AND BY EXISTING MATHEMATICAL FORMULA. In another study by Rubaihayo et al. formula. The closer the spacing, the more plants there will be per unit area. Our online plant calculator can work out how many plants you need based on the measurements you provide, making your next landscaping project go smoothly! Square Planting Pattern. 3), multiply it by 10,000, the area of a hectare. Another key parameter you need to aid your calculation is the spacing of your intended crop. The use of plant population formula is the most effective and cheapest method. Plant populations can be measured in two ways: OPTION 1 1. Population density – Population density is the number of people per unit of area, usually hectare or square kilometer. A preliminary investigation of onion cultivation in a southwest location in Nigeria. These three methods can be used to determine the total number of plant on your farm. When trying to calculate the amount of potato seed needed, the row spacing, within-row spacing, and seed size need to be taken into consideration. ), Ezumah and Osiru (1987) reported populations of 50, 000; 10, 000 and 10, 000 plants per ha at 1.0x0.02, 1.0x1.0 and 1.0x1.0 m, respectively. Plant population can be determined using several methods. Same applies to tomato, some tomato seeds are planted just one per hole, using nursery trays but in-situ, planting 2-3 seeds per hole is better. It is the manual method of the plant population calculator. (1996), Mutungamiri et al. Vines per Hectare Calculator. It is therefore concluded that science has been misinformed for several years through the use of this formula for the estimation of crop yield and other yield parameters. (1987) estimated the population of soybean (Glycine max Merill.) Mariga and O.A. While tomato plant population per hectare (10,000m) using a spacing of 60cm by 60cm with two seeds per hole is approximately 55,556 plants. Silim, 1996. Try it yourself to see how simple and easy it is. Using the same formula, Obuo et al. 1) on sole crop fields of tomato (Lycopersicon esculentum (L.) Mil. 1). Agronomists have long known that evenly spaced stands of plants resulting in optimum plant population, have a greater yield potential than unevenly spaced stand (Carlson et al., 2003). To calculate the total seeding rate (TSR) in number of seeds (grains) per hectare, divide the required (or recommended) seeding rate per hectare by the average seed weight or, given the ASR in number of seeds per sq. For example, 25 plants per metre multiplied by 100 then divided by 25 cm (10” row spacing) is 100 plants per square metre. To calculate the population density, you will divide the population by the size of the area. Spacing is very important in crop production; spacing is the optimum feeding area or the most convenient area required by a particular plant to thrive well. Osiru, 1987. Olubode, 1987. Since the plant population (Pp) is varying with respect to the dimension of the spacing l and b, we can minimize (or maximize) Pp subject to a constraint on the plant spacing. How to calculate Number of Plant per Hectare. Annual Report of Resource and Crop Management System, International Institute of Tropical Agriculture, Ibadan, Nigeria, pp: 139.Ezumah, H.C. and D.S.O. Under this scheme, we will have a plant population ranging from 25.000 to 60.000 plants per hectare. meter (no. Annual Report of Resource and Crop Management System, International Institute of Tropical Agriculture Ibadan, Nigeria, pp: 138.Mutungamiri, A., I.K. Row spacing: Metre: Vine spacing: Metre: Results: Vine density per Hectare # Orchard & Vineyard Calculators. of sole crop. 4. Lastly, you need to know the number of seeds you intend to plant per hole; this is called Seed rate. Convert the centimeters (cm) to meters (m). Response of vegetative development in Corchous olitorius L. to varying population densities. A comparison Monocropping, simple and complex mixing in a cassava-based rotation system. Adebooye, O.C., 1996. The experimental design was a randomized complete block. Plants Needed: Based on # Sq. for a six row planter, place a line across six rows). comb plants were not accounted for by the mathematical formula. and E. Hille, 1982. Tweet. CALCULATE PLANT POPULATION PER HECTARE OR JERIB (1 Ha = 10,000m² and 1 Jerib = 2000 m²) Multiply linear meters per Ha at a 0.42 meter row width by number of plants/meter. How to calculate Number of Plant per Hectare. It can be used to confirm planter accuracy during planting, or to evaluate crop stand after emergence. Let dL', dB' be the elemental length and breadth of farm field, respectively, while and dl', db' are the length and breadth of spacing, respectively, then Eq. of the physically counted plants with the estimate by mathematical formula showed On Corchorus olitorius L., Tayo (1990) reported populations of 250, 000; 500, 000 and 1.0 million per ha for plantings done at 20x20, 20x10 and 10x10 cm, respectively. and S. Tuwafe (Eds.). To determine on a jerib basis just divide the above number by five. Onion Newslett. The two values were thereafter compared to ascertain the reliability and accuracy of the mathematical formula. Thus, this loss can be represented as: The accurate plant population formula becomes: Therefore, for any given four dimensional field of length (L) and breadth (B), given a spacing of (lxb), plant population can be accurately estimated by Eq. When the above is evaluated, the number of plants on the farmland or plant population is determined. Fagbohun. The Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows. John Wiley and Sons, Canada.Spiegel, M.R., 1968. Distance Between Centers in Inches. Using just the right amount of pesticide and fertilizer minimizes the potential for personal, property, or environmental damage and maximizes consumers’ return on the dollar. Divide 10000 by the result of multiplying the between plant spacing and the between rows spacing as given in as shown below Calculate the amounts of vines needed to plant an hectare using metres for row spacing and vine spacing. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. Crop Sci. For example, with a spacing between lines of 3 meters and a spacing of plants within a line of 3 meters, a planting density of 1,111 trees per hectare … This constraint is subject to prevent overcrowding, thereby leading to an optimal yield. At two weeks after establishment on the main field, physical counting of the whole plants per plot was done for each crop. 4. Each crop was established on a 5x10 m (50 m2) plot and sowing was done at one plant per stand. Suppose that the spacing is subject to the constraint (or limitation), and if λ is the Lagrange multiplier, then, where λ has the unit (/m2). The analysis of functions for Minima and Maxima is well documented by Spiegel (1968), Swokowski (1979) and Salas and Hille (1982). Each crop was established on a 5x10 m plot, replicated three times and sowing was done at one plant per stand. Use a metre stick and count the seedlings per metre of row. 5. where the unit of measurement of L, B, l and b must be uniform (centimeter (cm), meter (m), etc.). Clay, 2003. NOTE: The unit of calculation here is meters. Share Site links. :) Notice that you can also use the plant spacing calculator to find the total rows and number of plants per row. Length in Feet. New Mexico Chile Task Force Report No. Distance Between Centers in Inches. A quadrat, usually a square-shaped material with equal dimension and made of wooden material, is placed on certain portions of the farm at random. Your email address will not be published. In this consideration, L', B', l' , b' may be expressed as a parametric function of another variable. The total area of a hectare is 10000 square metres. Example: 23,805.5 linear meters/Ha x 3.7 plants/linear meter = 88,095 plants/Hectare. plant harvesting (Paroissien and Flynn, 1998) etc. How to calculate Plant Population per hectare. Plant populations are not the same as seeding rates. The average of the result gotten with respect to the dimension of the quadrat is recorded and equated to the total land size to get the actual plant population of the whole farm. In agronomic research, especially in the conduct of field studies to evaluate crop performance, the determination of optimum sowing spacing and plant population per hectare (ha) is crucial. Example: Widely varying plant spacings such as 1 000 mm x 10 mm, 500 mm x 20 mm and 100 mm x 100 mm, all give a plant population of 100 plants … The planting spacings used were 50x50 cm, 20x20 cm, 20x20 cm and 1.0x1.0 m for tomato, amaranth, cocks comb and snake tomato, respectively. Effect of Spacing on Yield of Two Pigeonpea Cultivars in Uganda. 5 becomes. Repeat in 10 representative areas of the field/1 count per hectare and calculate the average. differ compared to the results of physical counting of plants on the field. of this formula is inaccurate because significant number of plants is not accounted 1. Ecological adaptation of some improved IITA soybean varieties in a humid forest ecosystem. 1. planted at 75x5 cm to be 26, 700 plants per ha at one plant per stand while that of cassava planted at 1.0x1.0 m was 10,000 plants per ha at one plant per stand. Then, you can now proceed to calculate plant population according to the spacing you want. Count the number of plants along the length. carrot) Plant spacing, on the other hand, refers to the ARRANGEMENTof plants on the area planted. The unit of land area should be square miles or square kilometers. Hence, (17) is a general form of Eq. The formula that we have derived is accurate for predicting the plant population provided that, all the conditions leading to the emergence of plant on the field such as soil condition, weather condition, cultural practices including planting depth and seed treatment, are under control and that there will be no missing plant stand. Plant population = 10 000 _____ between plants spacing (m)x between rows spacing row (m) An example If the between plant spacing of soybean is 5 cm and between row spacing is 45 cm what is the plant population per hectare? Work out the area counted, eg: 30cm x drill coulter width. How to calculate Number of Plant per Hectare. Calculus One and Several Variables with Analytic Geometry. of plants/m². Nig. Chivinge, 2001. To determine on a jerib basis just divide the above number by five. Crop Sci. Adebooye and A.J. (2001) and Rubaihayo et al. The recommended plant populations are generally higher for late-emerged seed. How to calculate Number of Plant per Hectare. Learn the formula. The unit of land area should be square miles or square kilometers. Calculate the seed rate of green gram for sowing 1 hectare of crop from the following: spacing=45cm×10cm germination %=80% 1000 grain weight =48g Solution: Plant population= 10000 0.45×0.1 =222222.22 Seed rate= 222222.22×48×100 80×1000×1000 =13.33 kg (Ans). Population Density is of various types and is calculated as per requirement. You can use square feet or meters if you are finding the density of a smallish space. These parameters must be accurate to get accurate answers. To calculate the population density, you will divide the population by the size of the area. It makes use of the same data as other methods. J., 9: 487-497.Direct LinkObuo, J.E., F.H. Place a 30cm stick/ruler or clipboard along a row. 5. Typical row spacing in the Red River Valley is 36 inches. and A.B. 4. While tomato plant population per hectare (10,000m) using a spacing of 60cm by 60cm with two seeds per hole is approximately 55,556 plants. The plant population formula is: Planting Area X Seed rate (Number of Seeds or Planting material per hole). Notify me of follow-up comments by email. Calculate the number of plants based on spacing in between rows of plants and the in row spacing of the individual plants for planting an area measured in acre(s) or hectare(s). Care was taken to ensure that the spacings were accurately measured out. Population density, persons per hectare in England Select component type Select component type Select component type Select component type Select component type LG Inform. Hitting the target: This six-year-old, two-hectare (five-acre) Pink Lady block on Malling Merton 106 rootstocks, and trained on an open Tatura system, produced a gross yield of 236 tons per hectare (236 bins per acre) and a total marketable yield of 219 tons per hectare (219 bins per … The Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows. Suppose we want to have 55.000 plants per hectare and our row width is 90cm. But these three methods are commonly used. Based on the result of the comparison, a new mathematical formula was developed for estimating plant population in a four dimensional field with accuracy. Afr. Generally speaking, for 36-inch rows, growers should be planting a minimum seeding rate of around 36,300 seed/A (2.5 seed/foot of row, or 2 seed every 9.6 inches hilldropped) in order to expect a final plant population of 30,000 plants/A. Mathematical Handbook of Formulas and Tables, Schaums Outline Series. 2. The width of rows and the spacing of plants in the row determines the plant population. Width in Feet. physical counting and by using the existing mathematical formula. Maize planting population per hectare (10,000m) with a seed rate of one per hole, using the plant population formula, is approximately 53,333 plants. Using the above formula (1), Dashiell et al. Once all these are provided, the device automatically provides the number of plants that will accommodate the provided land area. Adebooye , The condition in Eq. Make the necessary conversion to the same units of measurement. To figure planting rate, use this formula: You need to plant 7.9 seeds per foot of row to get six plants per foot. to the values obtained by using the mathematical formula (Eq. S.O. Agric., 18: 37-44.Carlson, C.G., T.A. For maize, 75cm by 25cm is used if one seed is to be planted per hole, 75cm by 50cm is used if two seeds are to be planted per hole and lastly, 75cm by 75cm is used if 3 seeds are to be planted per hole. Generally speaking, for 36-inch rows, growers should be planting a minimum seeding rate of around 36,300 seed/A (2.5 seed/foot of row, or 2 seed every 9.6 inches hilldropped) in order to expect a final plant population of 30,000 plants/A. The following standard formula can be used to calculate seeding rates once you have determined the target plant population, TKW and expected seedling survival rate: Seeding rate (kg/ha) = (target plant population/m2 x TKW in grams) ÷ expected seeding survival … Plant Calculator. Results showed that there was a significant difference between the estimate by physical counting and estimation by the existing mathematical formula. ICRISAT, Bulawayo, Zimbabwe, pp: 98-100.Paroissien, M. and R. Flynn, 1998. Seeding rate or planting rate refers to the number of soybean seeds planted per acre to attain a certain plant population. The total area of a hectare is 10000 square metres. Taking derivatives of (7), we have, The critical points (lc, bc) are obtained when. Alofe et al. There are two distance requirements for the calculation; the distance between tree rows and the distance between the trees themselves. Draw a line across all the planter rows (e.g. SSMG, 37: 1-16.Dashiell, K., H.C. Ezumah and S.O. Read […], […] of mulching plantain with sawdust. Using plant population calculator is the easiest method. Afr. O.C. for. 1. Effect of N and stand density on grain yield performance of maize in a southwest location. McGraw-Hill Book Company, New York.Tayo, T.O., 1990. The knowledge of determining the number of plants in a farm and number of seeds or planting material to use on a farm seems unknown to most farmers; people assume it is known to only professional farmers. 1 are not correct because significant number of plants on the plot are not taken into consideration. The tomato, amaranth and cocks comb were first raised in the nursery and then transplanted to the main field at 21 days after emergence, while the snake tomato was planted directly on the main field. Doerge and D.E. Our online plant calculator can work out how many plants you need based on the measurements you provide, making your next landscaping project go smoothly! How to calculate plant populations: By length of row. Place a 0.5m x 0.5m (0.25m²) quadrat diagonally so that one row goes vertically from one corner to the opposite corner. Now simply choose one of these options and start planting! The plantain suckers were planted early June 2019 with a plant population of 1200 using a plant spacing of 3m by […]. Site specific guidelines. Plant populations are not the same as seeding rates. OPTION 2 1. Take that number and multiply by 100 then divide by the seed row spacing in cm to get plants per square metre. In addition, I would indicate the plant population of the crops per hectare using the specified spacing. Based on the result of the comparison presented in Table 1, a new mathematical formula was developed for estimating plant population in a regular rectangular field with accuracy. In a study on cowpea (Vigna unguiculata (L.) Walp. This page will assist you in selecting products and Osiru and P. Okware, 2000. This therefore shows that the above formula does not estimate accurately The Corn Population Chart provides a quick guide on how corn population varies by row width and average seed spacing. Example: 40 000 plants per hectare (e.g. (1996) used the above formula to estimate sole maize (Zea mays L.) population planted at 75x50 cm at 1, 2 and 3 seeds per stand, resulting in 26, 700; 53, 300 and 80, 000 plants/ha, respectively. Hitting the target: This six-year-old, two-hectare (five-acre) Pink Lady block on Malling Merton 106 rootstocks, and trained on an open Tatura system, produced a gross yield of 236 tons per hectare (236 bins per acre) and a total marketable yield of 219 tons per hectare (219 bins per acre) from four harvests. Then you can estimate the cost of seeds and planting material yourself. This area is not the total area of your farmland but the planting area; in other words, it is the space you intend to let your plants occupy, this is always determined through mapping out. Calculating Potato Seeding Rate. Example: 23,805.5 linear meters/Ha x 3.7 plants/linear meter = 88,095 plants/Hectare. The concern of this study is to replace the inaccurate existing formula with an accurate one in order to eliminate the variation between theory and practice. For maize, the spacing becomes 0.75m by 0.25m and for tomato, the spacing is 0.60m. The term plant population refers to the number of soybean plants per acre. All the missing stands were supplied, leaving no room for vacancy. Plant population refers to the NUMBERof plants per unit area of land. 2. Any activity or operation carried out during the process of crop production has economic importance; fertilizer application is not left out. Plant population determination by physical counting gave higher values compared 1. that 32, 15.5, 6.1 and 6.1% of the snake tomato, tomato, amaranth and cocks * To convert measurements to a per hectare basis, multiply by 2.471. The first one is the use of plant population calculator; the other method is the study of plant population frequency by quadrat method and lastly, the use of plant population formula. Your crops need adequate space to garner all needed to facilitate their growth, such as nutrient, air, and water. Ajadi Seeding Rate, Plant Rate Any successful planting begins with identifying the purpose of the planting; selecting suitable species that meet the desired objectives of the resource concern; to ensure normal density of young shoot and a maximum yield, you need to determine the number of seeds planted per hectare (ha) or acre, and how much seed needs to be purchased. 5. Table 1 shows the results of plant population estimated by Likewise tomato, the spacing varies from 60cm by 60cm or by 1m. 2. The formula is flexible and can be used for direct estimation of plant population in any given four dimensional fields of sole crop. Thus, we must place the seeds within the row at a distance of 20,2 cm in order to have a plant population of 55.000 plants per hectare. ), amaranth (Amaranthus cruentus L.), cock`s comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). The plant spacing calculator will tell you how many plants you need in a rectangular and a triangular grid - here, 6,188 for a rectangular grid and 7,059 for triangular spacing. Plant spacing/plant population for machine harvest. How to calculate Plant Population per hectare. The calculator is an automated device or program that has been designed to determine the total number of the plant that will cover a portion of land by the aid of data provided by the farmer. Pp for non-regular field: We may propose plant population formula for a non-regular field, whose sides can be represented as a function of a variable. Since soybean seed is usually sold by weight rather than by number of seeds, you need to know the number of seeds per pound to figure pounds needed per acre. Effects of fertilizer o… the plant population in a given area of land. The number of trees per hectare, according to the spacing between the lines in a plantation and the spacing of plants within a line, is given in Table 4.1. Multiply the Planting Area by the Seed rate and then, divide the product by the Spacing or Planting distance. Let L and B be the length and breadth of the farm, respectively, while l and b are the length and breadth of the spacing on the farm land and N the number of seeds per stand. Performance of pigeon pea and its finger millet and sorghum intercrops. (2002) among several others have established that the plant population plays a significant role in the final crop yield under any given condition. Measure the amount of distance to give 1/1,000 th of an acre (Table 1) and draw another parallel line across the same six rows. The objective of this research Thus, Population Density = Number of People/Land Area. For most of the studies, the formula often used for the estimation of plant population per hectare (Pp) is: Using the above formula (1), Dashiell et al. Some maize seeds are very viable and are planted just one per hole. But, if you are reading this article; knowing how to determine plant population or the number of plants on your farm becomes easy henceforth. Isei, 1996. 13.Rubaihayo, P.R., D.S.O. From observations, the inadequacy of (2) is due to the loss of plants on two adjacent rows plus an additional plant. This depends on the viability and survival rate of the seeds. 3. Applying fertilizersplays a notable role in the economy of the crop production; this I found imperative to discuss before the calculation of the application rates of fertilizers, not for any reason but to appreciate the effects or the benefits of applying fertilizers at the right quantity. Theoretical estimation of maize population using the above formula by Mutungamiri et al. Use our handy calculator to determine the appropriate number of plants needed for an area. Definitions, Formulas & Examples. On the basis of the variation observed in the plant population estimation by physical counting and existing mathematical formula, a new formula was developed. The study of plant population frequency using quadrat is also easy but does not provide an accurate answer but an approximate answer as it a random based method. […], […] maize, plantain, cashew, yam, cassava, and other common crops. Total Square Footage. This calculator figures seed spacing and population. For planting part of an acre or hectare the value has to be entered in decimal format. Ife J. 3. Vines per Hectare. In: Improvement of Pigeonpea in Eastern and Southern Africa: Annual Research Planning, Silim, S.N. Calculate the seed requirement for rice in kg/ha for sowing 1 hectare of crop from the following: spacing of hill=20cm×20cm No. Vineyard Planting Density. NRI, UK., 6: 49-52.Alofe, C.O., O.C. The planting spacing used were 50x50 cm, 20x20 cm, 20x20 cm and 1.0x1.0 m for L. esculentum, A. cruentus, C. argentea and T. cucumerina, respectively. 15 and 16 show that 1. Maize planting population per hectare (10,000m) with a seed rate of one per hole, using the plant population formula, is approximately 53,333 plants. to determine with accuracy the plant population in a four dimensional field Seeding Rate, Plant Rate Any successful planting begins with identifying the purpose of the planting; selecting suitable species that meet the desired objectives of the resource concern; to ensure normal density of young shoot and a maximum yield, you need to determine the number of seeds planted per hectare (ha) or acre, and how much seed needs to be purchased. Try it yourself to see how simple and easy it is. 3. The literature is replete with information on the effect of spacing and plant density/population on growth; yield, diseases, pests, aspects of physiology, anatomy etc of different crops. the dimension indicated in (14) gives the minimum number of plant population. (1996) reported that cultivar ICPL 87091 pigeon pea (Cajanus cajan L.) required plant spacing of 60x20 cm (8.3 plants/m2 = 83,000 plants/ha) while cultivar KAT60/8 required 60x30 cm (5.5 plants/m2 = 55,000 plants/ha) for maximum grain yield. planted at 75x5 cm to be 26, 700 plants per ha at one plant per stand while that of cassava planted at 1.0x1.0 m was 10,000 plants per ha at one plant per stand.In a study on cowpea (Vigna unguiculata (L.) Walp. J. We claim that (2) is not capable of giving accurate number of plant population, since there is a discrepancy between plant population on the farm and that obtained using the formula (1) or (2). For example: To get maize plant population per hectare or tomato plant population per hectare, do the following. At the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria, field studies were conducted during the early season of 2003 and 2004 (April-July) to compare the plant population estimates by physical counting and by using the existing mathematical formula (Eq. However, some potatoes are planted at 34- and 38-inch row spacing. We can calculate our within row spacing in order to have the desired plant population, using the … It is the number of plants the farm can accommodate; through this, one will determine the number of seeds or sucker or other planting material to use for planting operation. (1987) estimated the population of soybean (Glycine max Merill.) At times, you need to plant more than one seed per hole but later thin-out some seedlings as they grow to accommodate the most vigorous and healthy ones. (2002), pigeon pea plant populations at 60x2, 60x30, 60x35, 60x40, 60x10 and 60x15 cm, were estimated to be 83, 000; 56, 000; 48, 000; 42, 000; 167, 000 and 111, 000, respectively at one plant per stand. The population of bulb onion (Allium cepa L.) planted at 20x25 cm at one plant per stand was reported to be 200, 000 plants/ha by Adebooye (1996). Once this is achieved, it becomes easy to know the number of seeds or planting materials needed for the crop to be planted. In this case, we solve the equation SS= 100.000/55*90 = 20,2 cm. You can use square feet or meters if you are finding the density of a smallish space. Seed Spacing: inches: Row Width: inches : Population: Click "Calculate" for Results Population: Row Width: inches : Seed Spacing: Click "Calculate" for Results just you can check the plant population per ha and multiply with weight per plant e.g. Ideally, planting 2 seeds per hole is better and safe. Firstly, you need to know the area of your farmland. So, determine the spacing you intend to adopt. Field studies were conducted at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria, to compare the plant population estimates by physical counting and by using existing mathematical formula, on sole crop fields of tomato (Lycopersicon esculentum (L.) Mil. I used this plant population calculator. Trop. Also all other data, for example, total number of leaves, total number of flowers, total number of fruits, total number of seeds, total number of diseased plants etc that are often estimated using the Eq. Obviously, if you have a hectare of land; you cannot use 100% of the land for your planting; you will need some space for shade and other farm responsibilities. Effect of maize density, bean cultivar and bean spatial arrangement on intercrop performance. Ft.: Thus, Population Density = Number of People/Land Area. On-farm experience has shown that the values obtained by the above formula Also, the mathematical formula was used to estimate the plants population for each crop. So determine the area you want your plants to occupy on the farmland, say 80-90% of the total farmland. With all these data determined, you can proceed to calculate the plant population or determining the number of seeds needed to adequately cultivate a specific planting area successfully using any of the aforementioned methods. 6 Effective Ways To Control Odor In Poultry Farm, 5 Cultural Practices That Assure High Crop Yield (Organic Farming), Managing A Farm Business: Pre-Planting And Post-Planting Operations, 3 MONEY RAISING IDEAS FOR ANY FARM BUSINESS, Know The Types Of Fungicides Used In Agriculture With Examples, 12 Best Type Of Tomatoes For Sandwiches, Salad, & Sauce, 10 Plants That Keep Bugs Away In Gardens & Field, How To Calculate Fertilizer Application Rate For Any Crop - Justagric, Standard Spacing Requirements And Plant Population Per Hectare, Effects of Mulching Plantain Farm With Sawdust - Justagric.com. This is quite correct because what you weren’t taught is obviously going to be unknown to you. […] Firstly, you need to determine the population of plants on your farm; for this example, the population of maize on an area of 350sqm is 233 maize plants. In another development, Carlson et al. This is true depending on the desired end result, such as plant productivity, J., 8: 49-62.Direct LinkSalas, S.L. Okurut-Akol and S.N. cabbage) or 100 plants per square metre (e.g. Spacing varies with the type and nature of crops; the spacing for maize and tomato varies with the breed of the seeds and the seed rate, that is, the number of seeds per hole. therefore was to develop a modified mathematical formula that could be used It is known that estimates of crop yield, crop performance, diseases and pests rating, water-use-efficiency, crop response to stress etc are always based on plant population estimates, therefore, accurate plant population estimates will give true and reliable information about these parameters. Most farmers find it easier and more reliable to count number of seeds per foot of row or seeds per acre instead of pounds or bushels per acre. The plants found in the quadrat are counted and this process is repeated for 3 or more portions on the farm. Several workers including Adebooye (1996), Alofe et al. Such data are a land area, planting distance or spacing, and seed rate. (2003) proposed a formula, which is a variation of (1) using the Excel spreadsheet. (2001) resulted in 24000 plants/ha at 90x45 cm and 37000 plants/ha at 90x30 cm at one plant per stand. Examples include Town/Overall Density, Gross Residential Density (GRD), and Net Residential Density. The first thing you must know is the area of your field. The optimization analysis of the farm field was also considered. The plant population definition is similar to the human population. CALCULATE PLANT POPULATION PER HECTARE OR JERIB (1 Ha = 10,000m² and 1 Jerib = 2000 m²) Multiply linear meters per Ha at a 0.42 meter row width by number of plants/meter. ), melon (Cucumeropsis edulis L.) and yam (Dioscorea rotundata Poir.
