), amaranth (Amaranthus cruentus L.), cocks comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). Row spacing: Metre: Vine spacing: Metre: Results: Vine density per Hectare # Orchard & Vineyard Calculators. J. Example: 23,805.5 linear meters/Ha x 3.7 plants/linear meter = 88,095 plants/Hectare. Typical row spacing in the Red River Valley is 36 inches. NOTE: The unit of calculation here is meters. Your crops need adequate space to garner all needed to facilitate their growth, such as nutrient, air, and water. ), 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. Silim, 1996. Alofe et al. Performance of pigeon pea and its finger millet and sorghum intercrops. Ideally, planting 2 seeds per hole is better and safe. Distance Between Centers in Inches. 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. Suppose we want to have 55.000 plants per hectare and our row width is 90cm. Afr. 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. The unit of land area should be square miles or square kilometers. 5. Vines per Hectare. 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). Table 1 shows the results of plant population estimated by It is the manual method of the plant population calculator. Another key parameter you need to aid your calculation is the spacing of your intended crop. Crop Sci. Notify me of follow-up comments by email. 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. Seed Spacing: inches: Row Width: inches : Population: Click "Calculate" for Results Population: Row Width: inches : Seed Spacing: Click "Calculate" for Results 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. Using the above formula (1), Dashiell et al. Then, you can now proceed to calculate plant population according to the spacing you want. Based on the result of the comparison, a new mathematical formula was developed for estimating plant population in a four dimensional field with accuracy. 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. 5. where the unit of measurement of L, B, l and b must be uniform (centimeter (cm), meter (m), etc.). 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. The Corn Population Chart provides a quick guide on how corn population varies by row width and average seed spacing. 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. 3. 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. Mathematical Handbook of Formulas and Tables, Schaums Outline Series. (2003) proposed a formula, which is a variation of (1) using the Excel spreadsheet. Clay, 2003. Once this is achieved, it becomes easy to know the number of seeds or planting materials needed for the crop to be planted. You can use square feet or meters if you are finding the density of a smallish space. 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 … The plantain suckers were planted early June 2019 with a plant population of 1200 using a plant spacing of 3m by […]. for a six row planter, place a line across six rows). 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. 4. In this consideration, L', B', l' , b' may be expressed as a parametric function of another variable. But, if you are reading this article; knowing how to determine plant population or the number of plants on your farm becomes easy henceforth. A preliminary investigation of onion cultivation in a southwest location in Nigeria. J., 8: 49-62.Direct LinkSalas, S.L. Thus, Population Density = Number of People/Land Area. 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. 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. 2. S.O. This page will assist you in selecting products and Seeding rate or planting rate refers to the number of soybean seeds planted per acre to attain a certain plant population. ICRISAT, Bulawayo, Zimbabwe, pp: 98-100.Paroissien, M. and R. Flynn, 1998. Results showed that there was a significant difference between the estimate by physical counting and estimation by the existing mathematical formula. Osiru, 1987. Lastly, you need to know the number of seeds you intend to plant per hole; this is called Seed rate. Hence, (17) is a general form of Eq. 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. The recommended plant populations are generally higher for late-emerged seed. Use our handy calculator to determine the appropriate number of plants needed for an area. 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. 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 Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows. Care was taken to ensure that the spacings were accurately measured out. Each crop was established on a 5x10 m (50 m2) plot and sowing was done at one plant per stand. Trop. 4. The width of rows and the spacing of plants in the row determines the plant population. 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. The optimization analysis of the farm field was also considered. Under this scheme, we will have a plant population ranging from 25.000 to 60.000 plants per hectare. In another development, Carlson et al. Divide 10000 by the result of multiplying the between plant spacing and the between rows spacing as given in as shown below All the missing stands were supplied, leaving no room for vacancy. Examples include Town/Overall Density, Gross Residential Density (GRD), and Net Residential Density. Repeat in 10 representative areas of the field/1 count per hectare and calculate the average. 3. Definitions, Formulas & Examples. Adebooye and A.J. Calculus One and Several Variables with Analytic Geometry. 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. Annual Report of Resource and Crop Management System, International Institute of Tropical Agriculture Ibadan, Nigeria, pp: 138.Mutungamiri, A., I.K. (1987) estimated the population of soybean (Glycine max Merill.) 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. There are two distance requirements for the calculation; the distance between tree rows and the distance between the trees themselves. 1. The experimental design was a randomized complete block. From observations, the inadequacy of (2) is due to the loss of plants on two adjacent rows plus an additional plant. The objective of this research […] 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. The study of plant population frequency using quadrat is a post-planting operation. cabbage) or 100 plants per square metre (e.g. Any activity or operation carried out during the process of crop production has economic importance; fertilizer application is not left out. Monocropping, simple and complex mixing in a cassava-based rotation system. The use of plant population calculator is a pre-planting operation. Effects of fertilizer o… 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 plants found in the quadrat are counted and this process is repeated for 3 or more portions on the farm. SSMG, 37: 1-16.Dashiell, K., H.C. Ezumah and S.O. 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. 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. How to calculate Plant Population per hectare. Try it yourself to see how simple and easy it is. ), amaranth (Amaranthus cruentus L.), cock`s comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). Sci., 24: 4-9. https://scialert.net/abstract/?doi=ja.2006.289.292, Plant population determined by physical counting and mathematical Example: 23,805.5 linear meters/Ha x 3.7 plants/linear meter = 88,095 plants/Hectare. Osiru and P. Okware, 2000. The use of plant population formula is the most effective and cheapest method. Your email address will not be published. Try it yourself to see how simple and easy it is. 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). Convert the centimeters (cm) to meters (m). The two values were thereafter compared to ascertain the reliability and accuracy of the mathematical formula. Place a 0.5m x 0.5m (0.25m²) quadrat diagonally so that one row goes vertically from one corner to the opposite corner. 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. 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. 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. Fagbohun. For maize, the spacing becomes 0.75m by 0.25m and for tomato, the spacing is 0.60m. The total area of a hectare is 10000 square metres. 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. At two weeks after establishment on the main field, physical counting of the whole plants per plot was done for each crop. Length in Feet. Likewise tomato, the spacing varies from 60cm by 60cm or by 1m. First convert cm to m 45cm =0.45m, 5 cm =0.05 2. In: Improvement of Pigeonpea in Eastern and Southern Africa: Annual Research Planning, Silim, S.N. (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. 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. :) Notice that you can also use the plant spacing calculator to find the total rows and number of plants per row. Olubode, 1987. COMPARISON OF PLANT POPULATION BY PHYSICAL COUNTING AND BY EXISTING MATHEMATICAL FORMULA. Calculate the seed requirement for rice in kg/ha for sowing 1 hectare of crop from the following: spacing of hill=20cm×20cm No. 1 are not correct because significant number of plants on the plot are not taken into consideration. ), melon (Cucumeropsis edulis L.) and yam (Dioscorea rotundata Poir. that 32, 15.5, 6.1 and 6.1% of the snake tomato, tomato, amaranth and cocks 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. But these three methods are commonly used. Plant populations are not the same as seeding rates. Ajadi Plants Needed: Based on # Sq. 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. 1. Plant population can be determined using several methods. How to calculate Number of Plant per Hectare. 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. (2001) resulted in 24000 plants/ha at 90x45 cm and 37000 plants/ha at 90x30 cm at one plant per stand. McGraw-Hill Book Company, New York.Tayo, T.O., 1990. Crop Sci. OPTION 2 1. Mariga and O.A. (2001) and Rubaihayo et al. (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. The term plant population refers to the number of soybean plants per acre. This therefore shows that the above formula does not estimate accurately Once all these are provided, the device automatically provides the number of plants that will accommodate the provided land area. It can be used to confirm planter accuracy during planting, or to evaluate crop stand after emergence. and S. Tuwafe (Eds.). Calculate the amounts of vines needed to plant an hectare using metres for row spacing and vine spacing. Thus, Population Density = Number of People/Land Area. The first thing you must know is the area of your field. Theoretical estimation of maize population using the above formula by Mutungamiri et al. 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. To figure planting rate, use this formula: You need to plant 7.9 seeds per foot of row to get six plants per foot. In this case, we solve the equation SS= 100.000/55*90 = 20,2 cm. Adebooye, O.C., 1996. (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. Adebooye , For example: To get maize plant population per hectare or tomato plant population per hectare, do the following. Distance Between Centers in Inches. Population Density is of various types and is calculated as per requirement. formula. Onion Newslett. 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. This is quite correct because what you weren’t taught is obviously going to be unknown to you. On-farm experience has shown that the values obtained by the above formula NRI, UK., 6: 49-52.Alofe, C.O., O.C. This depends on the viability and survival rate of the seeds. Place a 30cm stick/ruler or clipboard along a row. 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. 2. 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). 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. Use a metre stick and count the seedlings per metre of row. comb plants were not accounted for by the mathematical formula. 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 plant population definition is similar to the human population. The closer the spacing, the more plants there will be per unit area. 5. Vineyard Planting Density. Make the necessary conversion to the same units of measurement. Plant populations can be measured in two ways: OPTION 1 1. Multiply the Planting Area by the Seed rate and then, divide the product by the Spacing or Planting distance. Take that number and multiply by 100 then divide by the seed row spacing in cm to get plants per square metre. Some maize seeds are very viable and are planted just one per hole. 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. Agric., 18: 37-44.Carlson, C.G., T.A. How to calculate Number of Plant per Hectare. 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 … Isei, 1996. for. These three methods can be used to determine the total number of plant on your farm. 3), multiply it by 10,000, the area of a hectare. Square Planting Pattern. 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. Ft.: The total area of a hectare is 10000 square metres. We can calculate our within row spacing in order to have the desired plant population, using the … of the physically counted plants with the estimate by mathematical formula showed 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. Width in Feet. It makes use of the same data as other methods. Plant population determination by physical counting gave higher values compared This is true depending on the desired end result, such as plant productivity, For planting part of an acre or hectare the value has to be entered in decimal format. I used this plant population calculator. In a study on cowpea (Vigna unguiculata (L.) Walp. 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). * To convert measurements to a per hectare basis, multiply by 2.471. 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. the dimension indicated in (14) gives the minimum number of plant population. The analysis of functions for Minima and Maxima is well documented by Spiegel (1968), Swokowski (1979) and Salas and Hille (1982). (1987) estimated the population of soybean (Glycine max Merill.) The plant population formula is: Planting Area X Seed rate (Number of Seeds or Planting material per hole). Each crop was established on a 5x10 m plot, replicated three times and sowing was done at one plant per stand. 1) on sole crop fields of tomato (Lycopersicon esculentum (L.) Mil. […], […] maize, plantain, cashew, yam, cassava, and other common crops. Afr. plant harvesting (Paroissien and Flynn, 1998) etc. 5 becomes. Plant Calculator. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. How to calculate Number of Plant per Hectare. 1. of this formula is inaccurate because significant number of plants is not accounted 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. The condition in Eq. (2002) among several others have established that the plant population plays a significant role in the final crop yield under any given condition. Okurut-Akol and S.N. 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! 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! Population density, persons per hectare in England Select component type Select component type Select component type Select component type Select component type LG Inform. John Wiley and Sons, Canada.Spiegel, M.R., 1968. 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. O.C. Response of vegetative development in Corchous olitorius L. to varying population densities. to determine with accuracy the plant population in a four dimensional field 4. How to calculate plant populations: By length of row. Effect of N and stand density on grain yield performance of maize in a southwest location. 1). The Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows. Effect of Spacing on Yield of Two Pigeonpea Cultivars in Uganda. Plant populations are not the same as seeding rates. Read […], […] of mulching plantain with sawdust. Vines per Hectare Calculator. meter (no.
