Effect of foliar application of gibbrellic acid on pigeonpea [Cajanus cajan (L.)] under rainfed conditions

Abstract

A field experiment was conducted at the Agriculture Research Station (Dr. PDKV), Buldana during 2016, to study the effect of foliar application of gibbrellic acid on pigeonpea [Cajanus cajan (L.)] under rainfed conditions. In pigeonpea, 10 treatments comprising gibbrellic acid–management practices (application of 25, 50, 75 ppm GA3 at flowering, pod development stages and control) were tested. Results indicated that two applications of 75 ppm GA3 at flowering and pod development stages recorded significantly number of branches /plant, number of pods/ plant, seed index and grain yield than no application of the GA3. The same treatment recorded higher rain water use efficiency and higher gross returns.
