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 that is needed to facilitate their growth, such as nutrients, air and water. The plants found in the quadrat are counted and this process is repeated for 3 or more portions on the farm. An accurate estimate of plant population per acre can be obtained by counting the number of stalks in a length of row equal to 1/1000 of an acre. With this test grade calculator you'll easily find out the test percentage score and grade. 0000005440 00000 n
Observe the species in the first quadrant and mark them as species A. When you evaluate the above, you will be able to determine the number of plants on the farmland (i.e. Hb``` bE8V0p ! m. Step 2. But these three methods are commonly used: These three methods can be used to determine the total number of plants on your farm. 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. Convert the centimetres (cm) to metres (m). Spacing in between the rows and the plants in a row, measured in centimetres. Plant population is the number of plants in an area of land. Try it yourself to see how simple and easy it is. OgidiOlu Farms.

Depending on the kind of crop you want to grow, you can also measure the plant yield that you'd get! These parameters must be accurate to get accurate answers. 100% (1 rating) a) required seeds = plant population per hec / germination % = 40/80 =1/2 kg 500gm of seeds per hec is the amount of the required seed b) 1 hectare = 10000m2 area between two seeds = 0.75m X 0.5m = 0.375m2 two seeds are sown in a single hill in same . or, Plant to . 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. (Standard Deviation/Mean) X 100 With 10 m x 10 m triangular planting, the calculated plant population in one hectare will be 115. Your email address will not be published. (1987) estimated the population of soybean (Glycine max Merill.) For example: To get maize plant population per hectare or tomato plant population per hectare, do the following. . 39. 20 Kg C. 30 Kg D. 40 Kg. meter = Mean number per 0.25 m. 2 0.25. It makes use of the same data as other methods. Another vital importance of growing an optimum plant population is to avoid overpopulated fields or high plant density that can lead to plants competing for food, water, and space. Some estimates for the number of seeds per kilogram are as follows: The formula for calculating plant population is: Plant population = (field area x number of plant per stand) / ((plant spacing + walkway width) x row spacing). It is calculated by dividing the number of seeds planted by the number of acres. If you want to buy seeds, it is good to know the right amount to buy based on your evaluated plant population to avoid buying more than required. These are plant population density (determines number of cobs and kernels harvested in a given area), the shelling percentage, and the amount of water in the harvested grains. This is quite correct because what you werent taught is obviously going to be unknown to you. Transcribed image text: a) Calculate . I have long struggled to see why we are told to plant at 50-55,000 seeds per hectare and establishing 40-45,000 plants in Kenya, because nobody else in the world achieves optimum yields from planting this low. You can determine the best soybean population for a 15-inch spacing between rows by dividing your farm area by the product of your spacing between each soybean plant or seed and 15-inches. The average of the result derived 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. Therefore the Plant population of potatoes per ha is 37037. However, if you want to find the plant population per area of land, as is the case when planning field cultivation, use the formula: Plant population = (field area x number of plant/stand) / ((plant spacing + walkway width) x row spacing). The plants found in the quadrat are counted and this process is repeated for 3 or more portions on the farm. Spacing is the optimum feeding area or the most convenient area required by a particular plant to thrive well. %PDF-1.3

This is always determined through mapping out. Divide 10000 by the result of multiplying the between plant spacing and the between rows spacing as given in as shown below. Plant spacing . Expert Answer. For human populations A . This depends on the viability and survival rate of the seeds. formula to calculate seed rate per hectare. Knowing your BMR (basal metabolic weight) may help you make important decisions about your diet and lifestyle. Number of Plants per Acre or Hectare. Seed requirements of 2 - 4kgs per hectare to achieve a plant population of upto 10 000 plants per hectare Butternuts can be grown on a wide range of soils, fertile soils with adequate drainage are preferable, ideal soils are sandy loams or silty loams which warm up rapidly . For maize, the spacing becomes 0.75m by 0.25m and for tomato, the spacing is 0.60m. Plant population can be determined using several methods. This area is not the total area of your farmland but the planting 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). You can switch between plants per hectare or plants per acre depending on your evaluation and use the result of the plant population calculator to compare early-season and late-season crop population or evaluate crop losses and replanting strategy. 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 total area of a hectare is 10000 square metres. The C:AVA boss also believes that optimum plant population is necessary and he recommends 12,500 plants per hectare, with the spacing of 1mx80cm. Sometimes you may have a target plant density or plant population for a particular species (such as 2 plants per m 2), and you need to find out how to calculate the plant spacing between each plant. NOTE: The unit of calculation here is metres. The plant population per hectare was estimated using the following formula (Adebooye et al. plant population). 10 Kg B.
