Abstract:
A field experiment was conducted during rabi season of 2019-20 at Odisha University of Agriculture and Technology, Bhubaneswar under East and Southeast Coastal Plain Zone of Odisha to study the effect of various weed management practices on yield and economics of chickpea (Cicer arietinum L.). The experiment was laid out in randomized block design replicated thrice with eight treatments such as control plot (weedy check), weed free plot, pre-emergence application of pendimethalin @ 750 ga.i. ha^-1, pre-emergence application of pendimethalin @ 750 ga.i. ha^-1 followed by hand weeding at 30 DAS, pre-emergence application of oxyfluorfen @ 50 ga.i. ha^-1, pre-emergence application of oxyfluorfen @ 50 g a.i. ha^-1 followed by hand weeding at 30 DAS, post emergence application of quizolofop-p-ethyl @ 50 g a.i. ha^-1 and post emergence application of quizolofop-p-ethyl @ 50 g a.i. ha^-1 followed by hand weeding at 40 DAS. Pre-emergence application of pendimethalin or oxyfluorfen coupled with one hand weeding resulted in 42.4 and 47.2% higher weed control index than their lone application, respectively. Pre-emergence application of oxyfluorfen followed by one hand weeding yielded maximum grain (1311.3 kg ha^-1), which was at par with pre-emergence application of pendimethalin with one hand weeding. The highest net return of Rs. 42,945 ha^-1 was obtained in weed free treatment and was followed by pre-emergence application of oxyfluorfen with one hand weeding, which gave net profit of Rs. 39,932 ha-1 with the highest benefit: cost ratio of 2.66.
