Seed value
A metric indicating the percentage of pure and viable seeds within a batch, essential for determining the effective sowing rate.
Также говорят: sowing value, agricultural quality
Seed value is calculated by multiplying the percentage of physical purity by the percentage of germination, divided by one hundred. This metric is fundamental for precision agriculture, as it dictates the actual amount of viable seed needed to achieve a target plant population per hectare.
By understanding the seed value, farmers can adjust their seeding rates to compensate for lower quality lots, ensuring that the field reaches its full potential without wasting seeds or leaving gaps. Proper calculation significantly impacts the economic efficiency of crop production.
A common error is basing the sowing rate strictly on the total weight of the seed bag, ignoring the biological viability of the contents. Failing to account for seed value often results in poor stand establishment and increased pressure from competitive weeds due to sparse crop development.
