Abstract

A field experiment was conducted to assess the growth, productivity and profitability of rice (Sukhadhan-3 variety) under different methods of weed management at Bhanu-11 Rupakot, Tanahun during rainy season 2017. The experiment was laid out in randomized complete block design with three replications and ten treatments. The phenological, growth, yield and yield attributing characters were observed in the experiment. Results revealed that maximum grain yield (5.91 ton ha-1) was obtained in application of butachlor at 4 days after transplanting (DAT) which was statistically at par with all other treatments except single manual weeding, single cono-weeding and non-weeding plots (3.66 ton ha-1). The highest grain yield obtained from this treatment was might be due to higher number of effective grains per panicle (203 grains), less sterility (6.4%), high test weight (30.7g) with good harvest index (38.4%). Although the single application of butachlor as pre emergence spray showed highest grain yield which seems economically viable and profitable practice to the farmers but it is not environmentally safe to the whole universe.

评价不同杂草管理方法下水稻(Sukhadhan-3)的生长、生产力和盈利能力

在2017年雨季，在塔那洪邦巴努-11鲁帕科特进行了田间试验，以评估不同杂草管理方法下水稻(Sukhadhan-3)的生长、生产力和盈利能力。试验采用随机完全区组设计，3个重复，10个处理。在试验中观察了其物候、生长、产量和产量归因特性。结果表明，丁草胺在移栽后4 d的产量最高(5.91 t hm -1)，与除单人工除草、单协同除草和不除草(3.66 t hm -1)外的其他处理具有统计学意义上的同等水平。单穗有效粒数较高(203粒)，不育性较低(6.4%)，试重较高(30.7g)，收获指数较高(38.4%)，产量最高。虽然单次喷施丁草胺的产量最高，对农民来说似乎是经济可行和有利可图的做法，但对整个世界来说并不安全。
