Anil Kumar Jangade, GP Banjara, Tarun

The present investigation entitled “Bioefficacy of broad spectrum herbicides for weed management in chickpea (Cicer arietinum L.)” was carried out at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) during rabi season 2017-18. The soil of experimental field was clayey (Vertisols) in texture, locally known as “Kanhar” which was low, medium and high in available N, P2O5 and K2O, respectively. The experiment was laid out in Randomized Block Design with three replications. The treatment consisted of Pendimethalin 30 EC @ 1.0 kg ha-1 PE + One hand weeding at 30 DAS (T1), Pendimethalin 38.7 CS @ 1.0 kg ha-1 PE (T2), Pendimethalin 38.7 CS @ 1.0 kg ha-1 PE + one hoeing at 30 DAS (T3), Sulfentrazone 39.6 EC @ 50g ha-1 PE + one hoeing at 30 DAS (T4), Fenoxaprop-p-ethyl 9.3 EC @ 60g ha-1 POE at 25 DAS (T5), Pendimethalin 30 EC + Imazethapyr 2 % (Ready mix ) @1.0 kg ha-1 PE (T6), Pendimethalin 30 EC + Imazethapyr 2 % (Ready mix) @1.0 kg ha-1 PE + one hoeing at 30 DAS (T7), Pendimethalin 38.7 CS @ 1.0 kg ha-1 PE + Imazethapyr 2% (tank mix) @ 1.0 kg ha-1 (T8), Hand weeding at 30 DAS (T9), Weed free (hand weeding at 20 and 40 DAS) (T10), Weedy check (T11). The chickpea variety Vaibhav was grown as test crop on November 15, 2017 and harvesting was done on March 07, 2018.
