A field experiment was conducted during the year 2017-2018 at Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (Uttar Pradesh) to study the effect of various herbicides on growth attributes and nutrient uptake in sugarcane (Saccharum officinarum L.). The experiment comprises nine treatments laid out in Randomized Complete Block Design (RCBD) replicated thrice. The treatment consists of viz.T1- Diuron @ 2.4 kg/ha PE(Pre-emergence), T2- Diuron @ 3.2 kg/ha PE, T3- Diuron @ 2.4 kg/ha 2-4 leaf stage of weed, T4- Diuron @ 3.2 kg/ha 2-4 leaf stage of weed, T5-Paraquat @ 0.5 kg/ha EPo(Early post emergence), T6-2,4-D Na+ salt @ 2.6 kg/ha 2-4 leaf stage of weed, T7- Metribuzin @ 1.5 kg/ha PE,T8–Hand weeding (60, 90 and 120 DAP) and Untreated control (T9) also included to make comparison of the treatments. The results have been found that all the weed control measure significantly improved the crop growth parameter and nutrient uptake of crop in comparison to weedy check. Among all the weed management practices hand weeding was found significantly superior over rest of the treatments, however in chemical weed management practices application of diuron @3.2 kg/ha at 2-4 leaf stage of weed recorded statistically more Nitrogen, Phosphorus and Potassium uptake of crop thandiuron applied pre-emergence, metribuzin, paraquat and 2,4-D. Moreover all the growth attributes number of shoots, shoot height, and dry weight of shoot was also recorded maximum in diuron @3.2 kg/ha at 2-4 leaf stage of weed among all the herbicides.
