Impact of various tillage practices i.e. control, cultivator and mould board (MB) plough on the seed yield of mungbean (Vigna radiata L.) was evaluated at Arid Zone Research Institute, Dera Ismail Khan, Pakistan during kharif 2006 and 2007. Tillage practices showed significant effect on all parameters except days to flowering over control during kharif 2006. Use of cultivator produced significantly higher plant height (69.85cm), number of pods per plant (16.92), grains per pod (10.90) and seed yield (931 kg/ha) with 24-69 percent increase over MB plough and control. Similarly during kharif 2007, tillage practices also significantly affected all growth parameters except flowering and maturity over control, although both the tillage practices appeared to be non-significant with each other. However, use of cultivator in general gave maximum pods per plant (11.30), grains per pod (10.25), 1000 grain weight (37.43 g) and seed yield (611 kg/ha) with 37 percent increase over control and was at par with MB plough. Shallow tillage with cultivator showed the ability for moisture conservation near root zone of the crop which contributed towards increased seed yield under rainfed conditions.
