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

... aximum 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 T 1 :(100%RDP through Inorganic + 20cm × 20 cm) at 60 days after sowing. However maximum Crop growth rate (2.21 g/m 2 /day) at 15-30DAS were recorded with the application of T 9 (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 T 2 (100%RDP through Inorganic +25cm× 25cm) as compared to other treatments.
