Abstract

Field experiments were conducted for three seasons under rainfed vertisols of Kovilpatti from 1981-82 to 1983-84 to evaluate the performance of blackgram under compartmental bunding, raised bed and ridges and furrows system with and without farm yard manure application at 10 tonnes/ha in mitigating the adverse effect of drought. These treaments were superimposed with foliar spraying of two percent solutions of DAP and Urea at the flowering phase. The results of pooled analyses revealed the superiority of foliar application of DAP or urea over water spray alone. Soil fertility was not influenced by the treatments, Farm yard manure application has signifi- cantly increased the soil moisture status.
