Abstract:
A field experiment was carried out to study the efficacy of different pre and post-emergence herbicides and microbial inoculation against Phalaris minor and on growth, yield and economics of wheat. The experiment was performed in randomized blocked design with three replication and seventeen treatments in rabi season 2018-19 at CCS Haryana Agricultural University, Hisar. Significantly minimum weed count (2.4 m^-2) and dry weight (2.3 g m^-2) and maximum weed control efficiency (92.5%) and visual control of Phalaris minor (91%) was recorded with application of pendimethalin 1000 g ha^-1 (JAS) fb pinoxaden + metribuzin (tank mix) 50 + 105 g ha^-1 at 35 DAS while in case of broadleaved weeds lower density and biomass accumulation and higher weed control efficiency (92.4%) was observed under pendimethalin 1000 g ha^-1 JAS fb sulfosulfuron + metribuzin as a tank mix 25 + 105 g ha^-1 at 35 DAS. In case of plant height at 60 and 90 DAS (54.7 cm and 79.3 cm, respectively), number of tillers per meter row length at 60 and 90 DAS (109.3 and 106.7, respectively), grain yield (5761 kg ha^-1), harvest index (41.3%), gross returns (Rs. ha^-1 138810), net returns (Rs. ha^-1 57266), and B:C (1.70) was recorded higher with application of pendimethalin 1000 g ha^-1 (JAS) fb pinoxaden + metribuzin (tank mix) 50 + 105 g ha^-1 at 35 DAS which was significantly higher than weedy check but at par with the weed free treatment.
