Description |
The field experiment entitled “Studies on weed management in chickpea (Cicer arietinum L.) under irrigated conditions” was conducted at Students’ Research Farm, College of Agriculture, Kaul (Kaithal) Chaudhary Charan Singh Haryana Agricultural University, Hisar during rabi season of 2010-11. The experiment was laid out in Randomized Block Design with three replications consisting of twelve weed control treatments (clodinafop at 60 g/ha at 45 DAS, pinoxaden at 50 g/ha at 45 DAS, clodinafop at 60 g/ha at 45 DAS + one hoeing at 70 DAS, pinoxaden at 50 g/ha at 45 DAS + one hoeing at 70 DAS, pendimethalin at 1000 g/ha as PRE, trifluralin 1000 g/ha as PPI, pendimethalin at 1000 g/ha as PRE fb clodinafop at 60 g/ha at 45 DAS, trifluralin at 1000 g/ha as PPI fb clodinafop at 60 g/ha at 45 DAS, pendimethalin at 1000 g/ha as PRE fb pinoxaden at 50 g/ha at 45 DAS, two hand weeding, weedy check and weed free). The dominant weed flora was Chenopodium album, Medicago denticulata and Phalaris minor. Pendimethalin effectively controlled the population of Chenopodium album, Medicago denticulate and Phalaris minor. Pinoxaden and clodinafop were found effective in controlling Phalaris minor. Pinoxaden was found slightly phytotoxic to chickpea plants, which later on recovered at 75 DAS. Trifluralin was phytotoxic to chickpea crop and its application resulted in lower plant height of chickpea plants at earlier stage of crop growth, but did not cause mortality of crop. The highest grain yield was obtained in weed free treatment followed by two hand weeding. Weedy condition throughout crop season resulted in 68 and 65 per cent reduction in chickpea yield as compared to weed free and two hand weedings respectively. Pre-emergence application of pendimethalin at 1000 g/ha fb post-emergence use of pinoxaden at 50 g/ha applied at 45 DAS produced maximum grain yield of chickpea amongst herbicidal treatments. |
