The plants found in the quadrat are counted and this process is repeated for 3 or more portions on the farm. J. The total area of a hectare is 10000 square metres. To calculate the population density, you will divide the population by the size of the area. 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). J., 8: 49-62.Direct LinkSalas, S.L. In addition, I would indicate the plant population of the crops per hectare using the specified spacing. 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. NOTE: The unit of calculation here is meters. Convert the centimeters (cm) to meters (m). Ideally, planting 2 seeds per hole is better and safe. (1996), Mutungamiri et al. 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. ), amaranth (Amaranthus cruentus L.), cock`s comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). 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. Olubode, 1987. 1. Plant spacing/plant population for machine harvest. Calculus One and Several Variables with Analytic Geometry. and E. Hille, 1982. Seed Spacing: inches: Row Width: inches : Population: Click "Calculate" for Results Population: Row Width: inches : Seed Spacing: Click "Calculate" for Results How to calculate Number of Plant per Hectare. Annual Report of Resource and Crop Management System, International Institute of Tropical Agriculture Ibadan, Nigeria, pp: 138.Mutungamiri, A., I.K. Site specific guidelines. 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. 3. To figure planting rate, use this formula: You need to plant 7.9 seeds per foot of row to get six plants per foot. 3), multiply it by 10,000, the area of a hectare. that 32, 15.5, 6.1 and 6.1% of the snake tomato, tomato, amaranth and cocks […] 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. Example: 23,805.5 linear meters/Ha x 3.7 plants/linear meter = 88,095 plants/Hectare. 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. 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. This page will assist you in selecting products and Alofe et al. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. Also, the mathematical formula was used to estimate the plants population for each crop. (1987) estimated the population of soybean (Glycine max Merill.) On the basis of the variation observed in the plant population estimation by physical counting and existing mathematical formula, a new formula was developed. Example: 40 000 plants per hectare (e.g. Sci., 24: 4-9. https://scialert.net/abstract/?doi=ja.2006.289.292, Plant population determined by physical counting and mathematical Distance Between Centers in Inches.
