Abstract
Two field experiments were conducted at the central farm of Bangladesh Agricultural Research Institute, Gazipur during 2008-2009 and 2009-2010 to study the short-term effect of different tillage depth and cropping patterns on soil bulk density, infiltration rate and crop productivity. Treatment consists of three tillage depths (minimum tillage depth; medium tillage depth up to 10-12 cm and deep tillage up to 20-23 cm) and three cropping patterns (wheat –fallow- T.aman; Wheat- mungbean-T.aman; wheat-dhaincha-T.aman).Tillage depth, cropping pattern and their interaction  showed significant influence on soil bulk density, infiltration rate and crop productivity. Minimum tillage performed the best whereas, the minimum tillage and deep tillage performed better and worst regarding soil bulk density and  infiltration rate. Wheat –dhaincha –T.aman cropping pattern performed the best regarding yields,soil bulk density and infiltration rate followed by wheat- mungbean-T. aman and then by wheat-fallow-T.aman cropping pattern. The interaction of minimum tillage  and  wheat -fallow-T.aman cropping pattern performed the best regarding soil bulk density and infiltration rate.
 Key words: Plough pan, deep tillage, cropping pattern and biomass incorporation
