Studies conducted between 2003 and 2005 on black soils of Malwa region brought out that deep tillage plays a vital role in increasing the productivity of the crops through reduced infestation of weeds and increased water retention capacity of soil consequent upon improvement in its physical environment as indicated by lower values in bulk density of soil. This not only led to increasing productivity of soybean but also made the planting of rabi crops feasible without pre-sowing irrigation. The studies further revealed that the waste land reclaimed by spreading excavated soil from tank can immediately be brought under cultivation for soybean based cropping system. Successful raising of rainfed soybean ( kharif) followed by gram ( rabi) has been demonstrated on such reclaimed land.
