Abstract

To secure an economic return from any crop, the adoption of an optimum seed rate is important. Apart from the other factors that influence crop-yields, such as manuring and tillage, the return to the cultivator is secured to a great extent by adjustment of the quantity of seed he uses per acre. : Seed rate directly influences the population or stand of the crop, which in turn, influences the ultimate yield. At the same time, a given seed rate cannot be rigidly specified for any particular crop, since it is itself governed by various factors such as (1) the particular variety used; (2) the normal rainfall and other climatic factors of the region; (3) the physical nature of the soil, like its water-holding capacity; (4) the supply of available plant food it contains; (5) irriga- tional and other facilities and (6) manuring.
