Definition of Seed Rate

Seed rate may be defined as the amount of seed required for a unit area of land to grow any crop successfully. In other words, the amount of seed required to raise a crop successfully on a given land is called a seed rate for that crop of the land. Finally, the amount of seed that is required to be planted in a unit area of land is called the seed rate.

Seed Rate Formula

The following formula calculates seed rate:

Where,

WTS = Weight of thousand seedlings in gram
DPP = Desired plant population
PSA = Pure Percentage of safety allowance
PP = Percentage of purity
PG = Percentage of germination

Objectives of seed rate calculation

To ensure the number plant population in the field.
To reduce the wastage of seeds.
To know in advance the amount of seed to be required for a particular land.
To increase the yield and quality of a crop.
To reduce the cost of cultivation of crops.

Factors affecting seed rate calculation

Following factors are considered for determining the seed rate –

Desired plant population (DPP)
Percentage of germination (PG)
Purity percentage (PP)
Pure Percentage of safety allowance (PSA)
Weight of seed.
The number of seeds per pit.
Planting method.
Soil productivity.
Varied morphology.
Growing season.
Viability of seed.
Age of seed.
Size of seed.
Objectives of crop cultivation – Food purpose, Seed purpose.
