Abstract
The reduced yield under conventional tillage is due to more crop-weed competition and more dry matter accumulation by the weeds(Kumar et al. 2018). Due to zero weed competition, weed-free treatments yielded the highest grain yield of all weed managementpractices. In contrast to this, the lowest grain yield was obtained in weedy treatment due to season-long weed competition. Maximum yield under W8 is due to broadspectrum activity of these herbicides (Sharma et al. 2014, Sunil et al. 2021). The use of zero tillage reduced weed incidence and suppression, leading to higher grain yields. Therefore, zero tillage and metsulfuron 20% wp 4 g a.i./ha + clodinafop propargyl 15% wp 60 g a.i./ha should be practiced for minimizing weed growth and maximizing the yield.
常规耕作方式下产量下降是由于作物与杂草竞争加剧和杂草积累干物质增多(Kumar et al. 2018)。由于无杂草竞争，在所有杂草管理措施中，无杂草处理的粮食产量最高。与此相反，杂草处理由于整个季节的杂草竞争，籽粒产量最低。W8下的最高产量是由于这些除草剂的广谱活性(Sharma et al. 2014, Sunil et al. 2021)。免耕减少了杂草的发生和抑制，从而提高了粮食产量。因此，为了减少杂草生长，提高产量，应实行免耕和20%的甲磺隆(4 g a.i./ha) + 15%的丙丙醇(60 g a.i./ha)。
