Chickpea, Clodinafop-propargyl + Na-acifluorfen, Pendimethalin, Sorghum residue, Weed management, Zero tillage
An experiment was conducted during 2019–20 at Rani Lakshmi Bai Central Agricultural University (RLBCAU), Jhansi to evaluate the effect of tillage and weed management treatments on weeds and productivity of chickpea grown after sorghum. Major broad-leaved weeds were: Anagallis arvensis (48%), Spergula arvensis (12.3%), Medicago denticulata (8.6%), Melilotus alba (8.0%); and narrow-leaved, Cyperus rotundus (17.0%) and Dactyloctenium aegyptium (2.7%). Adoption of zero tillage (ZT) and ZT+ residue retention increased mean grain yield of chickpea by 10.6 and 21.1%, respectively over the conventional tillage (CT). Pre-emergence application (PE) of pendimethalin 1.0 kg/ha followed by (fb) post-emergence application (PoE) of clodinafop-propargyl + Na-acifluorfen 122.5 g/ha at 30 DAS controlled weeds effectively and resulted in 8.6, 19.3 and 43.5% more grain yield than pendimethalin fb hand weeding, pendimethalin alone and unweeded check, respectively. It was concluded that clodinafop-propargyl + Na-acifluorfen proved to be a good substitute for hand weeding at 30 DAS but its dose and timing of application need to be further standardized at different locations.
