ABSTRACT
In a field experiment conducted during rainy (Kharif) seasons on direct seeding (DSR) at optimum moisture condition and transplanting (TPR) in puddled fields by taking short and medium duration varieties of rice, grain yield under these two methods were at par during initial two years but were 15.2% and 9.1% less in DSR in subsequent yezors. The reduction in yield in DSR was attributed to the heavy infestation of weeds in subsequent years and also delay in first manual weeding beyond 20 days after sowing. The percolation rate was about 15% less in lPR than DSR however, the total water use was almost the same in both methods. Average water use efficiency (NUE) was 10.7% more in TPR than DSR. DSR gave only 16% less net returns during initial two years and net return further decreased in subsequent years. There was no significant interaction between varieties and methods but medium duration varieties gave higher yield, WUE, and net returns over short duration variety.
