摘要
摘要:杂草严重影响水稻的产量和品质。旱稻系统的杂草问题更为严重。2017年雨季,在尼泊尔surket Dasarathpur NARC研究站开展田间试验,评价不同杂草管理处理对旱稻杂草动态、产量和经济的效率和经济性。试验设对照、农民手工除草、旱地除草、单手除草、手除草加双嘧菌酯钠和双嘧菌酯加双嘧菌酯钠6个处理,采用单因素RCBD设计,4个重复。戊二甲基灵加双嘧菌酯钠对杂草的防治效果最好。同一处理籽粒产量最高(2.63 t /ha),对照区最低(0.99 t /ha)。在旱稻中,喷甲脒加双嘧菌酯钠的净收益和B: C比最高,是最有效和最经济的杂草治理方案。
Comparative Economics of Weed Management Treatments in Upland Rice at Western Mid Hill of Nepal
ISSN: 2582-6239 Abstract: Weeds cause drastic reduction on yield and quality of rice. The weeds problem is more severe in upland rice system. The efficiency and economics of different weed management treatments on weed dynamics, yield and economics of upland rice were evaluated by carrying out field experiment during rainy season of 2017 AD at NARC research station, Dasarathpur, Surkhet, Nepal. The experiment consisted of six treatments viz: control, farmer’s practice hand weeding, dry land weeder, pendimethalin with one hand weeding, hand weeding plus Bispyribac sodium and pendimethalin plus bispyribac sodium which were tested in one factor RCBD design with four replications. Pendimethalin plus bispyribac sodium was found efficient among all the treatments for the weed control. The highest grain yield (2.63 ton/ha) was also observed under the same treatment while lowest yield under control plot (0.99 ton/ha). The pendimethalin plus bispyribac sodium recorded the highest net returns and B: C ratio and was the most efficient and economical weed management option in upland rice.
