Abstract:
An experiment was conducted at Department of Plant Physiology, B. A. College of Agriculture, Anand Agricultural University, Anand with a view to study the impact of plant growth regulators and chemicals on growth and quality in green gram [Vigna radiata L.] cv. GAM-5 during the summer 2021. The experiment was arranged in randomized block design with three replications having ten treatments which comprise of T1 (CaCl2 1%), T2 (KNO₃ 0.5%), T3 (KNO₃ 1%), T4 (GA₃ 25 mg/l), T5 (GA₃ 50 mg/l), T6 (GA₃ 100 mg/l), T7 (NAA 25 mg/l), T8 (NAA 50 mg/l), T9 (NAA 100 mg/l) and T10 (control). The results revealed that significantly maximum chlorophyll content (31.99, 44.06, 58.55 and 14.90 SPAD) and leaf area ratio (42.80, 28.28, 19.10 and 12.13 cm² g^-1) at 30, 45, 60 DAS and at harvest, respectively, while higher seed protein 25.23% at harvest. Significantly maximum leaf area duration (6.49, 10.48 a n d 10.46 days) and crop growth rate (8.95, 15.08 and 2.80 g m² day^-1) at 30-45 DAS, 45-60 DAS and 60 DAS-at harvest was recorded with the foliar application of GA₃ 25 mg/l. Application of plant growth regulators and chemical particularly GA₃ 25 mg/l application found to be most suitable for the productivity and quality of green gram.
