Abstract
A field experiment was conducted during the cropping season of 2013-14 at Patancheru, Telangana to find out the economic weed management option and to study the impact of weed management practices on yield of pigeonpea under two different soil types (Alfisol and Vertisol). Pigeonpea (Cajanus cajan L.) is a versatile legume crop in many parts of the world. In India, the productivity of pigeonpea has remained stagnant due to the several constraints in pulse production. Among the several constraints, associated with pigeonpea weed infestation has a lion’s share. Herbicides were applied in each plot of Alfisol and Vertisol according to the dose and the twelve same set of treatment were replicated thrice in randomized block design. Result revealed that Alfisol perform better in term of weed control efficiency while the observed yield and net return were more in Vertisol compared to Alfisol. In Alfisol, significantly lower weed index of 12.48% was recorded in imazethapyr 10% SL @ 60 g a.i./ha at 15 DAS (T3) while imazethapyr 10% SL @ 40 g a.i./ha at 15 DAS (T2) recorded the index of 12.23% in Vertisol which gave higher seed yield of 1907 and 2345 kg/ha in Alfisol and Vertisol, respectively. The use of herbicide to suppress weeds during the early vegetative stage of pigeonpea was effective in both soil types.
