Effect of moisture regimes and weed management on weeds, yields and economics of direct seeded rice

Author(s): Alisha Kumari, Rajan Kumar, Vinod Kumar, Sweeti Kumari and Shabana
Abstract: A field experiment was conducted during rainy (kharif) season of 2016 at Crop Research centre Pusa, Bihar to investigate the “Effect of Moisture Regimes and Weed Management on weeds, yield and economics of Direct Seeded Rice”. The treatments consisted of three moisture regimes in main plots and five weed management practices in sub plots. The results showed that weed density and weed dry weight was minimum and grain yield, gross return and net return were found to be maximum with I1 moisture regimes which were significantly superior to I2 and I3. B: C ratio was maximum with I1 moisture regime which was statistically at par with I2 and significantly superior to I3.With regard to weed management lowest weed density and weed dry weight was found with W4 treatment which was significantly superior to all the treatments. Maximum weed control efficiency and minimum weed index was observed with W3 among all the herbicidal treatments, though weed control efficiency was the highest with W4 treatment. Grain yield and gross return were recorded maximum with W4 treatment of weed management which was significantly superior to W2, W1 and W5 but was statistically at par with W3 treatment. Net return was recorded maximum with W3 treatment which was significantly superior to W4 and W5 but was statistically at par with W2 and W1. B: C ratio was recorded maximum with W­2 treatment which was significantly superior to W4 and W5 but was statistically at par with W3 and W1 treatments.
