Abstract: A field experiment entitled “Efficacy of different post-emergence herbicide in chickpea (Cicer arietinum L.)” was carried out at the farm of AICRP on Weed Management, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during Rabi season 2016-17.The investigation was carried out to study the relative efficacy of post emergence herbicides on weed control in chickpea, as well as to study the phytotoxic effect on crop, growth and yield of chickpea. The experiment was laid out in Randomized Block Design with eleven treatments replicated thrice. The treatment comprised of different post-emergence herbicides in different doses and were compared with the cultural methods. The soil of experimental was fairly uniform and levelled and low in available nitrogen, and organic carbon, medium in phosphorus, rich in available potassium and slightly alkaline in reaction. Chickpea (JAKI-9218) was sown on 11th Nov 2016 at 30 x 10 cm spacing with fertilizer dose of 25:50:30 NPK kg/ha. The results revealed that, among the varioustreatments under study, weed free treatment (2Hand Weeding) recorded significantly higher values of major parameters whereas, in herbicidal treatments, the maximum growth and yield attributes were recorded with treatment of Oxyflourfen @ 150 g a.i./ha as a post emergence application at 40 DAS which was at par with treatment Imazethapyr 10% @ 50 g a.i./ha. Among the post emergence herbicides, reduction in weed density, weed dry matter, higher weed control efficiency (84.31%) and lowest weed index (5.07%) was found with Oxyflourfen @ 150 g a.i./ha POE 40 DAS and higher weed index in weedy check (45.90%). Oxyflourfen @ 150 g a.i./ha POE 40 DAS was found most economical with maximum value of GMR (88358 Rs ha-1), NMR(58884 Rs ha-1 ) and B: C ratio (3.00). The net return per hectare was more under cultural practice i.e. two hand weeding at 30 and 50 DAS but the difference was not much when compared to effective post emergence herbicide (Oxyflurofen @ 150 g/ha).
