Abstract
The field experiment was done during Rabi season of 2011-12 at Agronomy Research Farm of NDUA&T, Kumarganj, Faizabad, UP. The fresh biomass and dry biomass nodules plant-1 (mg), branches numbers and grain yield significantly supreme was noted in weed free plot. Fresh and dry biomass, branches number was obtained statically at par with treatments pendimethalin 1000 g ha-1 PE, or fb quizalofop 60 g ha-1 PoE or clodinafop 60 g ha-1 PoE at 45 and 60 DAS, 60 DAS and at 90 DAS. The minimum Fresh and dry biomass, branches number was noted with rest all the treatments. Whereas drastic toxicity was detected tracked by oxyfluorfen 200 g + fb clodinafop 60 g ha-1 PoE and pendimethalin 1000 g PE fb imazethapyr 75 g + quizalofop 60 g ha-1 PoE, separately. The greatest drop in grain yield of chickpea were noted in PE application of pendimethalin 750 g tracked by mutual PoE application of quizalofop-ethyl 60 g + oxyfluorfen 200 g ha-1 at 35 DAS. The utmost net economic returns and B-C ratio were noted in PE application of pendimethalin 1000 g and PoE application of clodinafop 60 g ha-1 and PE application of pendimethalin1000 g and PoE application of quizalofop-ethyl 60 g ha-1 at 35 DAS and the net monetary returns and B-C ratio were in negative with application of pendimethalin 750 g PE followed by mutual PoE application of quizalofop-ethyl 60 g + oxyfluorfen 200 g ha-1at 35 DAS and PoE application of oxyfluorfen200 g + quizalofop-ethyl 60 g ha-1 PoE.
