To use the calculation you will need to know the following: the plant population you want to establish for your crop, the thousand grain weight of the seed, the germination percentage (%) of the seed, the expected crop emergence - this is . DDjBJ}gv& E;ylaIv|>0d&WNC72z*2*;*LktiVWA0RMfwbCByREk=u Keep in mind that 1 ton = 1000 kg = 2.200 lbs. It is calculated by dividing the number of seeds planted by the number of acres. The coefficient of variation (CV%) is calculated by formula :-A. The seed rate depends on spacing or plant population, test weight, germination percentage. Generally, if the seedbed and planter are good, about 90 to 95% of germinated seedlings will become established. So determine the area you want your plants to occupy on the farmland, say 80-90% of the total farmland. You should know the population and the surface area of the region. 90 Population Per Hectare to Population Per Square Kilometer = 9000.

There is only one ear on one plant, its weight is 220 g, and its grain yield is 80%. For the quincunx planting pattern, the number of maincrop hills is calculated using the same formula for square planting. Note that you must use the same units in the plant population density calculation formula. 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. Multiply the Planting Area by the Seed Rate and then, divide the product by the Spacing or Planting distance. (Our.

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. So, determine the spacing you intend to adopt. Lastly, you need to know the number of seeds you intend to plant per hole; this is called Seed rate. Both the formula and the online calculator allow you to adjust the emergence percentage. Weight Of Okra Seeds Per Hectare/Acre # Plant spacing impacts the number of . It also makes use of the same data as other methods. Provide the information in the plant population calculator to find the exact weight of seeds you need for the calculated plant population. This depends on the viability and survival rate of the seeds. . It only provides an approximate answer. Top Use: Calculate Seeding Rate - Field Size (acre):1 Row Spacing (inch):15 5.7 seeds per inch. The formula to find plant spacing from plant density is different depending on the type of grid. 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. The study of plant population frequency using quadrat is a post-planting operation. 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). To achieve this population density of Okra plants within a single hectare of land, they estimated the following spacing requirements: 30 cm between plants within a row (intra) 60 cm between rows within the field (inter) Okra seeds are to be planted at the rate of about 4-5 seeds per foot. The use of the plant population formula is the cheapest and most effective method. Lastly, you need to know the number of seeds you intend to plant per hole. Multiply the Planting Area by the Seed rate and then, divide the product by the Spacing or Planting distance. 0000002097 00000 n 4 Population Per Hectare to Population Per Square Kilometer = 400. Convert the centimeters (cm) to meters (m). Since soybean seed is usually sold by weight rather than by number of seeds, you need to know the number of seeds per . 0000008976 00000 n plant populace= ten thousand among plant life spacing (m) among . 0000004663 00000 n Planting Area X Seed rate (Number of Seeds or Planting material per hole) It will compute the number if the plants are placed on a rectangular grid, and the number if they are placed on a triangular grid.
