Effect of foliar application of gibberellic acid on growth, yield and economics of blackgram

Abstract

A field experiment was conducted at the research field of Pulses Research Unit, Washim Road, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) during Kharif season of 2018, to study the effect of foliar application of gibberellic acid on growth, yield and economics of blackgram (Vigna mungo L.). In blackgram, 11 treatments comprising gibberellic acid management practices (application of 15, 30, 45 ppm GA3 at flower and pod initiation stages and control) were tested. Results indicated that two applications of 30ppm GA3 at flower and pod initiation stages recorded significantly number of pods/cluster, length of pod (cm),number of grains/pod, number of pods/plant, grain yield/plant (g), grain yield (kg/ha) and gross monetary returns than no application of the GA3. The same treatment recorded higher rain water use efficiency and higher gross returns.
