A field experiment was conducted at Agriculture Research Station, Janawada, Bidar to study the efficacy of sequential application of herbicides on growth and yield of chickpea (Cicer arietinum L.) in north eastern transitional zone of Karnataka. Among the different herbicide treatments in chickpea the application of pendimethalin 38.7 CS @ 700 g a.i. ha -1 fb imazethapyr 10 SL @ 75 g a.i. ha -1 in chickpea crop recorded significantly higher seed yield (2198 kg ha -1 ) due to higher growth parameters viz., plant height (42.32 cm), number of branches (6.89), leaf area (6.99 dm 2 plant -1 ), leaf area index (2.33), leaf area duration (47.38 day) and yield parameters viz., number of pods (40.01), pod weight per plant (19.23 g plant -1 ), seed yield per plant (7.69 g plant -1 ) and test weight (18.32 g plant -1 ). This was mainly due to lower weed density 0.5 m -2 (3.12) and weed index (9.77%) compared to other herbicide treatments respectively. However, weed free check recorded significantly higher growth and yield parameters due to weed free environment maitained throught out the growth period of the crop compared to rest of the treatments.
