Abstract:
A field experiment was conducted during the rabi and summer seasons of 2020-21 and 2021-22 at C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, S. K. Nagar, Gujarat, India to study on integrated nitrogen management in wheat and its residual effect on summer green gram under North Gujarat condition. There were six integrated nitrogen management treatments to wheat and eighteen treatment combinations comprising residual effect of preceding six integrated nitrogen management treatments of wheat followed by three levels of recommended dose of nitrogen to green gram. Pooled results over 2 years indicated that, application of 50% RDN through inorganic source + 50% RDN through organic source to wheat resulted in significantly higher wheat grain equivalent yield (7745 kg/ha), higher system productivity (39.61 kg/ha/day) and system profitability (899 ₹/ha/day). Whereas direct application of 100% recommended dose of nitrogen to green gram, recorded significantly higher wheat grain equivalent yield (7288 kg/ha), higher system productivity (37.27 kg/ha/day) and system profitability (846 ₹/ha/day) of crop sequence. In economics of wheat-green gram crop sequence were recorded higher net return (98268 ₹/ha) and BCR (2.36) with the application of 50% RDN through inorganic source + 50% RDN through organic source to wheat’ whereas in case of levels of nitrogen 100% RDN recorded highest net return (74720₹/ha) and BCR (1.82) of wheat-green gram crop sequence.
