Online Published on 18 March, 2024. Abstract Rice (Oryza sativa L.) is an important kharif crop established either as direct seeded rice (DSR) and/or as puddled transplanted rice (PTR) in north-western India. We compared the performance of short duration (PR-126, n=63) and medium duration (PR-128; n=41 and PR-129; n=31) varieties under DSR and PTR methods at farmers' fields during kharif-2021. Mean rice grain yield did not differ significantly (p<0.05) among different establishment methods. The yield difference from average yield potential varied between 0.11 and 0.51 Mg ha-1 for DSR and between 0.19 and 0.42 Mg ha-1 for PTR. As compared with the district average, the rice grain yield was higher by 0.24-0.58 Mg ha-1 under DSR and by 0.27-0.50 Mg ha-1 under PTR. The technology gap of 1.52 Mg ha-1 for PR-126 was lower by ˜2.97 and ˜2.86-times than PR-128 and PR-129, respectively, and the extension gap of 1.32, 1.37 and 0.97 Mg ha-1 for PR-126, PR-128 and PR- 129, respectively was observed. As compared with PTR, the irrigation water use was significantly lower in DSR (by ˜15.9-20.1%) in three rice varieties. Per cent increase in irrigation water use efficiency in DSR method varied between 17.9-24.7%; the lowest for PR-128 and the highest for PR-129, while PR-126 in-between. These results revealed higher B-C ratio of 4.07-4.16 for DRS, as compared with between 3.25-3.33 for PTR method. The production efficiency was higher for DSR than the PTR method, regardless of the rice variety. The production efficiency was for PR-126 was higher by ˜18.4% than PR-128 and by ˜15.8% than PR-129 under DSR method.
