IMPACT OF LAND CONFIGURATIONS, IRRIGATION SCHEDULING AND WEED MANAGEMENT ON YIELD AND ECONOMICS OF CHICKPEA (Cicer arietinum L.)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 51
Abstract
The field experiment was conducted during Rabi 2013-14 at Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to study the impact of land configurations, irrigation scheduling and weed management on yield and economics of chickpea. The treatments comprised three land configurations (Flat bed, Broad bed furrow, Ridge-furrow); three irrigation schedules (Irrigation at branching, Irrigation at pod development, Irrigation at branching and pod development) as main plot treatments and three weed management (Weedy Check, Hand weeding twice at 25 and 50 DAS, Pendimethalin @1.0 kg ha-1 as pre emergence) as sub-plot treatments. These treatments were tested in split plot design with three replications. Ridge-furrow method resulted in significantly higher seed yield (1512.33 kg ha-1), gross monetary returns (₹74794 ha-1), net monetary returns (₹43991 ha-1) and benefit: cost ratio (2.40) over flatbed and broad bed furrow. Irrigation at branching and pod development gave appreciably higher seed yield of 1483.33 kg ha-1, gross monetary returns (₹73366 ha-1), net monetary returns (₹42089 ha-1) and benefit: cost ratio (2.31) over rest of the irrigation scheduling. Application of Pendimethal in @ 1.0 kg ha-1 PE resulted in 52.17 per cent more seed yield (1592.74 kg ha-1), gross monetary returns (₹79225 ha-1), net monetary returns (₹49504 ha-1) and benefit: cost ratio (2.66) over weedy check. However, hand weeding twice registered in significantly higher seed yield 1719.56 kg ha-1 and gross monetary returns (₹84998 ha-1) but had lower B: C ratio.
