Abstract

The mean, minimum and maximum requirement of different forms of N, P, and K were obtained by using quadratic equation from the field experimental data. The yields were regressed on 13 different forms of N, P and K indicating that if required nutrient is more than its mean available value then maximum yield occurs.
