Integrated weed management in chickpea (Cicer arietinum L.) under south Gujarat condition
Research Type
Departmental Research
Experiment Background
Losses due to weeds have been one of the major limiting factors in chickpea production most of the yield reduction due to weed competition occurs during the first six weeks after sowing therefore major emphasis on weed control should be given during this period. Good chickpea weed control involves utilizing all methods available and combining them in an integrated weed management system. But considering the present day labour scarcity and their higher wages for cultural and mechanical weed control, the economic feasibility of chickpea cultivation is quiet disturbed. Hence, the emphasis should be given to adopt the chemical methods of weed control to solve the problem of minimum available labour and their high cost. Only a few chemicals are available
