Title : Soybean (Glycine max. (L.) Merrill) Vegetative Growth and Yield Performance under Organic Manures Nutrient Management System in South-Eastern Rajasthan

Abstract :

A field experiment was conducted at Research Farm of Agricultural Research Station (Organic Block, field No. 14), Ummedganj, Kota during kharif season 2020 and 2021 on clay loam soil to study the “Soybean (Glycine max. (L.) Merrill) vegetative growth and yield performance under organic manures nutrient management system in South-Eastern Rajasthan” which was laid out in randomized block design with three replications. The experiment comprised of tenth treatments viz. T1 (Control), T2 (100 % OM + 10% CU), T3 (100 % OM + 5% Panchgavya), T4 (75 % OM + 25 % VC + 10% VW), T5 (50 % OM + 50 % VC + 10% VW), T6 (75 % OM + JA 500 L/ha), T7 (75 % OM + GJA 500 kg/ha), T8 (100 % OM + LCB 1250 ml/ha), T9 (75 % OM + LCB 1250 ml/ha), T10 (75 % OM + LCB 1250 ml/ha + 10% SG). In this experiment application of different organic sources were applied to the soybean variety “JS 20-34”. A critical examination of data revealed that significantly higher plant height 45, 60 DAS and at harvest (41.0, 52.6 and 56.1 cm), number of branches/plant 45, 60 DAS and at harvest (5.0, 5.4 and 6.2), total number of nodules/plant at 45 and 55 DAS (46.3 and 44.0), effective nodules/plant at 45 and 55 DAS (41.2 and 34.5), chlorophyll content at 45 and 60 DAS (3.39 and 3.87 mg/g), plant dry weight 45, 60 DAS and at physiological maturity (108.7, 193.0 and 369.7 g/mrl) and crop growth rate 30-45, 45-60 DAS and 60-at physiological maturity (13.90, 16.87 and 17.67 g/m2/day) were observed in application of 50 % OM + 50 % VC + 10% VW over control. Application of 50% OM + 50 %VC + 10% VW was recorded significantly higher number of pods/plant (46.0) number of seeds/pod (2.77), pod length (4.79 cm) and seed index (11.05), seed yield (2160 kg/ha), straw yield (3124 kg/ha) and biological yield (5284 kg/ha) as compared to over rest of treatments. It can be inferred from the economic assessment of data that all the different organic manures treatments recorded significantly higher gross return ( 128172), net return ( 93584), B: C ratio (2.71) and production efficiency (24.55 kg/ha/day) were recorded in application of 50% OM + 50% VC + 10% VW as compared to over rest of treatments.
