Abstract

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 weed dynamics and yield in sugarcane (Saccharum officinarum L.). The experiment comprised of nine treatments laid out in randomized complete block design replicated thrice. The treatment consisted 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 @ 0.5kg/haEPo (Early post emergence), T6-2,4-D Na+ salt @ 2.6 kg/ha 2-4 leaf stage of weed, T7- Metribuzin @ 1.5kg/ha, T8 – Hand weeding (60, 90 and 120 DAP) and Untreated control (T9) also included to make comparison of the treatments. The results showed all the weed control treatments significantly superior over weedy check. Hand weeding was found significantly superior over rest of the treatments. Among the herbicides diuron @ 3.2 kg/ha applied at 2-4 leaf stage of weed recorded lowest weed density, weed dry matter, nutrient removal, weed index and maximum weed control efficiency. The presence of weed reduce cane yield about 49.98% in comparison to hand weeding.The highest cane yield (88.81 t/ha) and net return (Rs.194550.60) was obtained with hand weeding, however highest B:C (2.03) was obtain with the application of diuron 3.2 kg/ha at 2- 4 leaf stage of weed.
