Abstract
A field experiment was conducted at Agricultural College and Research Institute, Killikulam during early Pishanam season of 2018-2019 to assess the effect of different irrigation practices through field water tube and weed management practices on water production parameters, grain and straw yield of transplanted rice. The experiment was laid out in strip plot design with three replications. The treatments comprised of three different methods of irrigation in vertical strips and four methods of weed management practices in horizontal strips. The experimental results showed that, field water tube method of irrigation at 10 and 15 cm depletion registered lower consumption of water with less number of irrigation, high water saving percentage, higher water use efficiency and water productivity than compare to continuous submergence of irrigation water. At the same time, maintaining weed free condition by hand weeding recorded low total water consumption with lesser number of irrigation. Weed free environment also increased the water use efficiency and water productivity of rice and it was followed by application of PE Pyrazosulfuron ethyl @ 20g a.i. ha-1 fb POEBispyribac sodium @ 25 g a.i. ha-1.The higher grain and straw yield (6753 and 7666 kg ha-1) of rice was recorded in continuous submergence with weed free environment. It was followed by irrigation management through FWT at 10 cm depletion of water coupled with application of PE Pyrazosulfuron ethyl @ 20g a.i. ha-1 fb POEBispyribac sodium @ 25 g a.i.ha-1.
