Influence of different plant growth regulators on growth parameters (LAI, AGR, CGR, RGR) of soybean (Glycine max L.)

Author(s): AJ Bhatiya, NV Nakum and KD Solanki
Abstract: A field experiment was conducted during the kharif 2021 at Cotton Research Station, Junagadh Agricultural University, Junagadh to study the “Effect of plant growth regulators on morpho-physiological, biochemical and yield parameters of soybean (Glycine max L.)” The investigation was carried out in Randomized Block Design with three replication. The experiment consisting of eleven treatments viz., IAA @ 100 & 150 ppm, GA3 @ 100 & 150 ppm, Kinetin @ 50 & 75 ppm, Salicylic acid @ 50 & 100 ppm, Brassinosteroid @ 0.1 & 0.25 ppm and control (water spray). Significantly the highest mean of growth character viz., AGR, CGR and RGR observed in treatment of GA3 @ 100 ppm at 40 and 50 DAS and followed by GA3 @ 150 ppm and IAA @ 100 ppm. The leaf area index (LAI) was increased up to 50 DAS and decreased thereafter due to senescence and ageing of leaves. Significantly the highest mean leaf area index was recorded in treatment GA3 @ 100 ppm at 60 DAS.
