Field experiments were conducted during the seasons of 1991-1992 to 1992-1994 to study the combined effect of foliar spray of 2% DAP, 0.5% zinc sulphate and endosulfan on the yield and yield attributes of rainfed cotton. Significant increase in seed cotton yield (305 kg ha'') was registered with the combined foliar application of insecticide (Endosulfan) and fertilizers (@% DAP and 0.5% zinc sulphate) on 45 DAS, following the recommended basal soil application of 40kg N ha and 20 kg P ha. The yield economics of the cotton also confirms the same treatment.
