Ecological weed management practices and seed bed preparation in sub-humid condition of Chitwan, Nepal / S. Marahatta in Journal of Agriculture and Forestry University, Volume 1 (2017)
[article]
Title : Ecological weed management practices and seed bed preparation in sub-humid condition of Chitwan, Nepal Material Type: printed text Authors: S. Marahatta, Author ; P. Gyawali, Author ; Sanjit Kumar Saha, Author ; Theer Bahadur Karki, Author Publication Date: 2017 Article on page: 89-101 p. Languages : English (eng) Keywords: hand weeding, sesbania co-culture, stale seed bed, weed index Abstract: The weeds are a major constraint of dry-direct seeded rice (DDSR) due to change in establishment methods and shifting weed flora towards competitive grasses and sedges. For optimizing the yield of DDSR through environmental friendly weed management practices, two field experiments were conducted during the monsoon season of 2014 on Chitwan, Nepal. First experiment was done
using a strip plot design to find the optimum seed rate and killing date of sesbania under ricesesbania co-culture whereas the second experiment was done by using a split plot to observe the efficiency of stale seed bed for weed control and to identify the best integrated weed management practice. The optimum seed rate of sesbania was 102 kg ha-1 and killing dates was 32 days. The sesbania co-culture with 100 kg ha-1 when killed at 28 days had produced significantly higher grain yield than sole Bispyribac Na application, and only 4.79% yield was loss than farmers’ practice of two hand weeding. In contrary to weed free, Pendimethalin followed by Bispyribac Na application and Pendimethalin followed by 2,4-D application produced statistically similar yield followed by sesbania co-culture with 100 kg seeds and killing at 28 days. During the monsoon rice, the
effectiveness of stale seed bed was not much greater (0.37%) than the normal seed bed.Link for e-copy: https://afu.edu.np/sites/default/files/Ecological_weed_management_practices_and_ [...]
