Abstract

To study the interaction effect of P and S on gingelly, field experiments were conducted during the year 1999 and 2000 at Agricultural Engineering College and Research Institute, Kumulur. The results revealed that the gingelly responded positively to both P and S application. Application of 100 kg P,O, and 40 kg S ha were found to be optimum to get the economic yield. The synergistic relationship of P and S were recorded upto 100 kg P,O, and 40 kg S ha beyond which an antagonistic relationship were noticed between P and S. Besides application of P increased the available S status irrespective of their levels.
