Effect of different plant growth regulators on yield parameters of cluster bean (Cymopsis tetragonoloba L. Taub.)

Abstract

A study was carried out at the was carried out during summer season of year 2024-25 at the Instructional farm Khudmudi, College of Horticulture and Research Station, Sankra, Patan, Durg (C.G.), to study the “Effect of different plant growth regulators on yield parameters of Cluster bean (Cymopsis tetragonoloba L. Taub.)”. The experiment was laid out in Randomized Block Design with ten treatments and three replications. The different treatment was, T0-Control, T2-NNA 60 ppm, T2-NAA 80 ppm, T3-100 ppm, T4-GA3 50 ppm, T5-GA75 ppm, T6-GA3100 ppm T7-CCC 500 PPM, T8-CCC 1000 ppm, T9-1500 ppm. Among the yield parameters pod weight(g), number of pod per plant, pod yield per plant(g), pod yield per plot (kg), total yield (q/ha) analysis and also for yield Amongst plant growth regulator CCC 1500 ppm gives beneficial better performance at yield parameters like maximum plant pod weight (1.77 g) a number of pod per plant (48.12) Pod yield per plant (85.32 g) pod yield per plot (2.30 kg) total yield (76.79 q/ha) minimum pod weight (1.58), number of pod per plant (31.60), pod yield per plant (49.85 g), pod yield per plot (1.35 kg) and total yield (44.87 q/ha) minimum was recorded in T0 Control, Hence, treatment T9 (CCC 1500 ppm) was considers as best performing treatment for yield peramerts of cluster bean of with foliar application of PGR (NAA, GA3, CCC).
