Combining tillage with herbicides is an economical and efficient method for weed management and yield improvement in wheat. A two-year study was conducted having three tillage levels viz. 2″ tillage (shallow tillage, ST), 4″ tillage (conventional tillage, CT) and 6″ tillage (deep tillage, DT). The weed control treatments were five including three herbicides i.e. bromoxynil + MCPA (a broad-leaf weed killer), fenoxaprop-p-ethyl (a grass killer) and isoproturon + carfentrazone (a broad-spectrum herbicide), along with a hand weeding (HW) and a weedy check (WC). Results showed that the recorded parameters were significantly affected by the varying tillage depths, herbicide applications and their interactions. The weed density and biomass were the highest in ST and the lowest in DT, while among the weed control treatments, the weed density and biomass were highest in WC and lowest in HW. On the other hand, the DT treatments resulted in highest number of spikes m⁻², 1000-grain weight (TGW), biological yield and grain yield; while ST showed the lowest values. Among the weed control treatments, the number of spikes, TGW, biological and grain yields were the highest in HW and the lowest in WC treatments. The herbicide isoproturon + carfentrazone performed the best among the three applied herbicides in diminishing the weed population density and biomass, and improving the number of spikes, TGW, biological and grain yields. In conclusion, the combination of deep tillage and herbicide isoproturon + carfentrazone can prove to be the best option for optimum weed management in wheat at higher altitudes.

将耕作与除草剂结合使用是一种经济有效的小麦杂草管理和增产方法。进行了为期两年的研究，具有三个耕种水平。2英寸耕作（浅耕，ST），4英寸耕作（常规耕作，CT）和6英寸耕作（深耕，DT）。杂草防治方法有五种，其中包括三种除草剂，即溴苯腈+ MCPA（一种阔叶除草剂），fenoxaprop-p-ethyl（一种杀草剂）和异丙隆+ carfentrazone（一种广谱除草剂），以及一种手动除草剂（ HW）和杂草检查（WC）。结果表明，记录的参数受到不同耕作深度，除草剂施用及其相互作用的显着影响。杂草密度和生物量在ST中最高，在DT中最低，而在杂草控制处理中，WC中杂草密度和生物量最高，HW中最低。另一方面，DT处理导致峰值的最大数量m⁻²，千粒重（TGW），生物产量和谷物产量；而ST显示最低值。在杂草控制处理中，花键数量，TGW，生物和谷物产量在硬汉中最高，而在硬汉中最低。三种除草剂中的异丙草隆+芬太尼除草剂在减少杂草种群密度和生物量，提高穗数，TGW，生物和谷物产量方面表现最佳。总之，在高海拔地区，深耕和除草剂异丙隆+卡芬曲酮的组合可被证明是小麦最佳杂草处理的最佳选择。
