| 1 | Tillage and residue management effect on soil properties,crop performance and energy relations in greengram(Vigna radiata L.)under maize-based cropping systems显示文摘Effect of tillage and crop residue management on soil properties,crop performance,energy relations and economics in greengram(Vigna radiata L.)was evaluated under four maize-based cropping systems in an Inceptisol of Delhi,India.Soil bulk density,hydraulic conductivity and aggregation at 0-15 cm layer were significantly affected both by tillage and cropping systems,while zero tillage significantly increased the soil organic carbon content.Yields of greengram were significantly higher in maize-chickpea and maize-mustard systems,more so with residue addition.When no residue was added,conventional tillage required 20%higher energy inputs than the zero tillage,while the residue addition increased the energy output in both tillage practices.Maize-wheat-greengram cropping system involved the maximum energy requirement and the cost of production.However,the largest net return was obtained from the maize-chickpea-greengram system under the conventional tillage with residue incorporation.Although zero tillage resulted in better aggregation,C content and N availability in soil,and reduced the energy inputs,cultivation of summer greengram appeared to be profitable under conventional tillage system with residue incorporation. | J.R.Meena Umakant K.Behera Debasis Chakraborty A.R.Sharma | 2015 | International Soil and Water Conservation Research2015，3，4： | 1 |
