Seed rate is the quantity of seed of a crop that is required to sow a unit area of land for optimum crop production. To maintain optimum plant population in the field for higher yield harvest. To prevent seed wastage from excess sowing such reduces the initial cost of production.
What is formula of seed rate?
Sowing rate (kg/ha) = target plant population (p/m2) x TGW (g) x 100. % germination x % emergence.
What is seed rate importance?
Seeding Rate
This is expressed in pure live seed (PLS) pounds per acre and is based on planting a predetermined number of live seeds per square foot to achieve a specific plant density. Having the proper plant density is important because it affects the overall health of the planting and the vigor of the plants.
How do you calculate seeds?
Take the total number of inches available for the crop and divide by the in- row crop spacing. For instance, 120 in. divided by 1 in. per pea seed equals 120 pea seeds.
What is the seed rate of sorghum?
Use seed rate of 30-35 kg/acre for sowing.
What is seed rate of wheat?
The recommended spacing to achieve this plant population is 45 cm between rows and 10-12 cm between plants within rows. A seed rate of 8-10 kg/ha is recommended to obtain required plant population.
What is the seed rate of cotton?

What does seed rate mean?
Definition. Seed rate is the quantity of seed of a crop that is required to sow a unit area of land for optimum crop production. Importance of determining seed rate. • To maintain optimum plant population in the field for higher yield harvest.
What is lower seed rate?
Low seed rates can occur due to uneven distribution or insufficient seed used. Crops can be surface-broadcasted (wet or dry), drill-seeded (using machines) or broadcasted and incorporated when sown on dry fields. Pre-germinated seed is typically used in wet direct seeding.
What is recommended seed rate?
Adopt a seed rate of 10 kg/ha for varieties and 5 kg/ha for hybrid.
What is the seed rate of rice?
Seed Rate : Use 20-25kg seed per hectare of fine ,30-35kg seed for medium and 35- 40kg seed for coarse paddy in nursery to transplant it in one hectare land.
What is the seed rate of maize?
about 25 kg/ha
Whatever the case, the minimum plant population for maize is 36,000 plants per ha. A seed rate of about 25 kg/ha is required, but this depends on the seed size. 10 kg is enough to plant 1 acre and 5 kg for half an acre. Small seed will go further, and give equal germination and yield performance as large seed.
What is pure live seed?
Pure live seed is the living seed of the intended crop that will germinate from a seed bag and accounts for the weight of the bag made up of impurities, weed seed, and other crop seed. Percent PLS in a seed bag varies, depending on the amount of pure seed in the bag as well as the germination rate of that seed.
What is the sowing time of wheat?
Wheat must be sown at the optimum time. Delayed sowing causes a gradual decline in the yield of wheat. The time of sowing is 25 October – November. For normal sown crop a spacing of 20 – 22.5 cm between rows is recommended.
What is sorghum used for?
Sorghum is used to make both leavened and unleavened bread. In Sahelian Africa, it is primarily used in couscous. Various fermented and unfermented beverages are made from sorghum. It can be steamed or popped and is consumed as a fresh vegetable in some areas of the world.
