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 greengram 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 greengram. Pooled results over 2 years indicated that, application of 100% recommended dose of nitrogen through inorganic source (urea) to wheat resulted in significantly higher growth attributes, yield attributes, grain yield (4613 kg/ha) and straw yield (5651 kg/ha) of wheat. In summer greengram, the residual effect of 100% recommended dose of nitrogen through organic source (organic source was applied at the rate of 1/3 nitrogen from each of FYM, vermicompost and castor cake) applied to wheat had found significant effect on growth attributes, yield attributes, seed yield (861 kg/ha) and stover yield (2003 kg/ha) of greengram. Direct application of 100% recommended dose of nitrogen to greengram, recorded significantly higher growth attributes, yield attributes, seed yield (850 kg/ha) and stover yield (1919 kg/ha) of greengram.
