Study of System of Crop Intensification (SCI) and Phosphorus Management on Growth, Yield and Economics of Greengram (Vigna radiata L.)

A field experiment was conducted during Zaid 2019 at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). To study the “System of Crop Intensification (SCI) and Phosphorus management on growth, yield and economics of Greengram (Vigna radiata)”. There were 10 treatments each replicated thrice. The treatment consists of 4 different spacing levels of (20cm×20cm), (25cm×25cm), (30cm×30cm), (35cm×35cm) and 2 different sources of application of phosphorus, 100% RDP through Inorganic, 50% RDP Inorganic + 50% Organic.. The experiment was laid out in Randomized Block Design. The results revealed that maximum growth attributes such as plant height (24.87cm), number of nodules (6.80 /plant) and dry weight (4.52 g/ plant) was obtained by application of T1:(100%RDP through Inorganic + 20cm × 20 cm) at 60 days after sowing. However maximum Crop growth rate (2.21 g/m2/day) at 15-30DAS were recorded with the application of T9 (100% RDP through Inorganic (Control) 30cm × 10cm). As well as significantly maximum yield attributes viz, pods per plant (16.80), grains per pod (10.37), Grain yield (1113.67 kg/ ha), Stover yield (2556 kg/ha) were recorded under 100%RDP through Inorganic + 20cm × 20 cm. However gross return (101778 ₹ ha), Net return (63444 ₹ ha) and B:C ratio (2.70) were showed their superiority with application T2 (100%RDP through Inorganic +25cm× 25cm) as compared to other treatments.
