Field experiments were conducted on heavy clay loam soil and medium light soil at two locations in Punjab, to quantify the impact of no-till and other resource conservation technologies into the rice phase of the rice-wheat system rotation. Both of these locations are in the rice-wheat crop rotation zone and have different soil types. Rice variety, Basmati-385 was transplanted in the first week of July. The wheat cultivar used was Pak-81. Optimum tillage along with 20 days puddling produced significantly higher yield (5729 kg per ha), root length (22.3cm), maximum root dry weight (15.5 g) and harvest index (32%). Highest sterility rate and maximum weed population was observed in minimum tillage at both locations. Total water losses were less at heavy clay loam soil as compared with the medium light soil.
