Growth, yield and economics of rain fed chickpea (Cicer arietinum L.) as influenced by integrated weed management
An experiment was conducted at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna, Madhya Pradesh in Rabi season of the years 2009-10. The experiment containing 12 treatments mechanical i.e. hand weeding at 25 and 50 DAS (Days After Sowing) and chemical i.e. pre emergence application of Alachlor @ 2 kg a.i./ha, Pendimethalin @ 1 kg a.i./ha, Oxyfluorfen @ 0.2 kg a.i./ha, and post emergence application of Imazethapyr @ 100 g a.i./ha at 30 DAS and in combination with Alachlor @ 1.5 kg a.i./ha as Pre-E + 1 HW 25 DAS, Pendimethalin @ 0.75 kg a.i./ha /ha Pre-E + 1 HW 25 DAS, Oxyfluorfen @ 0.15 kg a.i./ha Pre-E + 1 HW 25 DAS, Imazethapyr @ 75 g a.i./ha Post-E 30 DAS + 1 HW 50 DAS. These treatments were laid out in randomized block design. Growth parameters were recorded at successive crop growth stages, yield and yield contributing character recorded at maturity and economics of study was done after harvest. The weed population at 60 DAS was found to be minimum in Pendimethalin @ 0.75 kg/ha + 1 hand weeding at 25 DAS treatment and this treatments has been found suitable for higher seed production and economically viable in rain fed chickpea.
