A filed experiment was conducted at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna, Madhya Pradesh during winter ( Rabi ) season of 2019-20 and 2020-21 to assess the efficacy of herbicides on production and profitability of chickpea ( Cicer arietinum L.). The experiment was laid out in a randomized block design with ten treatments and three replications. The crop was sown as per the package of practices recommended for zone Kymore Plateau of Madhya Pradesh. The major monocot weed was Cynodon dactylon and dominant dicot weed was Chenopodium album at 30 days after sowing (DAS). At 30 DAS, significantly lower weed density (7.75/m 2 ) and biomass (2.70 g/m 2 ) were recorded with post-emergence application (PoE) of fomesafen (11.1% W/W) 220 g + fluazifop-p-butyl (11.1% W/W) 220 g/ha PoE at 20 DAS, followed by imazethapyr (35%) + imazamox (35%) 100 g/ha PoE at 20 DAS. The lowest weed index was noted with imazethapyr 55 g/ha PoE followed by pre-emergence application (PE) of pendimethalin 0.75 kg/ha and fomesafen 220 g + fluazifop-p-butyl 220 g/ha PoE at 30 DAS. Higher weed control efficiency (WCE) at 30 DAS was recorded with fomesafen 220 g + fluazifop-p-butyl 220 g/ha (70.6%) followed by hand weeding at 20 and 40 DAS (57.1%). However, fomesafen 220 g + fluazifop-p-butyl 220 g/ha PoE at 20 DAS and imazethapyr + imazamox 100 g/ha PoE at 20 DAS caused severe injury to chickpea plants and even mortality of a few plants. Significantly higher 1000 seed weight (183.0 g) and grain yield (1.79 t/ha) were observed with imazethapyr 55 g/ha PoE which was statistically at par with weed free check. Significantly higher net returns ( 70746/ha) and B:C ratio (3.97) were recorded with imazethapyr 55 g/ha PoE ( 70746/ha), followed by pendimethalin 0.75 kg/ha PE. The monetary efficiency ( 589.5/ha/day) of imazethapyr 55 g/ha PoE was statistically at par with weed free ( 541.3/ha/day) and was significantly higher than all other treatments.

The efficacy of a post-emergence herbicides in managing weeds in blackgram was evaluated during summer and rainy (Kharif) seasons of 2016 at University of Agricultural Sciences (UAS), GKVK, Bangalore, India. The experiments were laid in RCBD with three replications comprising of nine treatments. Major weed species observed were: Cyperus rotundus, Eleuisine indica, Dactyloctenium aegyptium, Borreria articularis, Echinochloa colona, Commelina benghalensis, Euphorbia geniculata, Phyllanthus niruri. The post-emergence application (PoE) of sodium acifluorfen 16.5% + clodinafop-propargyl 8% EC (206.25 + 100 g/ha) has attained significantly higher seed and haulm yield of blackgram (1305 and 2088 kg/ha, respectively) in summer 2016 and (1519 and 2253 kg/ha, respectively) in Kharif 2016, followed by sodium acifluorfen 16.5% + clodinafop-propargyl 8% EC (165 + 80 and 123.75 + 60 g/ha) (1192 and 1808 kg/ha, respectively) in summer 2016 and (1425 and 2095 kg/ha, respectively) in Kharif 2016. Similarly the weed control efficiency in summer and kharif 2016 was higher with sodium acifluorfen + clodinafop-propargyl (330 + 160 g/ha) PoE (93.20 and 91.0%, respectively) and it was followed by sodium acifluorfen + clodinafop-propargyl (206.25 + 100 g/ha) PoE (89.51 and 90.24%, respectively) when compared to weedy check. The increased yield was mainly due to a significant reduction in weed density and biomass, without any phytotoxicity to succeeding finger millet crop under semi-arid Alfisols.
