Abstract

A filed experiment was conducted at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (MP.) during rabi season 2019-20 and 2020-21 to assess the efficacy of herbicides for higher yield and productivity of chickpea (Cicer arietinum L.). Weed density was observed significantly lower in fomesafen 11.1% W/W @ 220 g + Fluazifop-p-butyl 11.1% W/W @ 220 g/ha at 20 – 25 DAS (10.84/m2 ) while, weed dry weight was recorded significantly least in imazethapyr 35 % + imazamox 35 % @ 100 g/ha at 20 – 25 DAS (4.50 g/m2 ). However, higher weed control efficiency was recorded under imazethapyr 35 % + imazamox 35 % @ 100 g/ha at 20 – 25 DAS (70.40%) followed by hand weeding at 20 and 40 DAS (63.48%) at 50 DAS. The weed index was noted lowest in imazethapyr 10% SL @ 55 g/ha at 20 -25 DAS followed by fomesafen 11.1% W/W @ 220 g + Fluazifop-p-butyl 11.1% W/W @ 220 g/ha at 20 – 25 DAS (15.90). Among the weed control plot, significantly superior grain yield, straw yield and biological yield (1798 kg/ha, 2338 kg/ha and 4136 kg/ ha) was recorded under imazethapyr 10% SL @ 55 g/ha at 20-25 DAS which exhibited statistically on par with weed free treatment. Harvest index (%) was numerically higher in imazethapyr 35 % + imazamox 35 % @ 100 g/ha at 20 – 25 DAS (52.50 %), respectively. Production efficiency was observed higher in imazethapyr 10% SL @ 55 g/ha at 20 -25 DAS (14.98 kg/day/ha) followed by pendimethalin @ 0.75 kg/ha PE (13.42 kg/day/ ha). The Phytotoxicity of herbicides fomesafen 11.1% W/W @ 220 g + Fluazifop-p-butyl 11.1% W/W @ 220 g/ ha at 20 – 25 DAS and imazethapyr 35 % + imazamox 35 % @ 100 g/ha at 20 – 25 DAS on the crop were observed severe which caused severe injury to crop plant and even few plants were almost destroyed.
