A field experiment was laid out at College Farm, Agricultural College, Aswaraopet, Bhadradri Kothagudem Dist., Professor Jayashankar Telangana State Agricultural University, Telangana State during kharif, 2016 and 2017. Experiment was laid out in split plot design with three treatments under main plots i.e. chemical fertilizer alone, integration of vermicompost and FYM along with inorganic fertilizers and four sub plots as weed management practices with pre and post-emergence herbicides along with hand weedings. Results revealed that highest grain and straw yields, gross and net returns were highest with 75% RDF + 25% N through vermicompost and Bispyribac sodium 10% SC @25 g ha-1 (Pre-Emg.) fb (Pyrazosulfuron ethyl 10 % WP @ 25 g ha-1 + 2, 4-D 80% WP @ 0.5 kg a.i ha-1) + HW @ 50 DAS. However, B-C ratio did not show any significant influence with nutrient treatments while highest B-C ratio was found with Bispyribac sodium 10% SC @25 g ha-1 (Pre-Emg.) fb Hand weeding @ 20, 40 DAS.
