Productivity and economic efficiency of chickpea as influenced by land configurations, irrigation scheduling and weed management

Abstract

A field investigation was conducted during Rabi 2013-14 and 2014-15 at J.N.K.V.V, Jabalpur to study the productivity and economic efficiency of chickpea as influenced by land configurations, irrigation scheduling and weed management. The treatments comprised 3 land configurations (Flat bed, Broad bed furrow, Ridge-furrow); 3 irrigation schedules (Irrigation at branching, Irrigation at pod development, Irrigation at branching and pod development) as main plot treatments and 3 weed management (Weedy Check, Hand weeding twice at 25 and 50 DAS, Pendimethalin @1.0 kg a.i.ha-1 as pre emergence) as sub-plot treatments. The experiment was laid out in a Split plot design with 3 replications. Ridge-furrow method resulted in significantly higher seed yield (1512.33 and1743.01 kg ha-1), Production efficiency of seed (12.60 and 14.53 kg ha-1 day-1), economic efficiency (RS. 366.59 and 643.25 ha-1day-1), partial factor productivity of N and K (75.62 and 87.15 kg ha-1) and P (25.21 and 29.05kg ha-1) over flatbed and broad bed furrow. Irrigation at branching and pod development gave appreciably higher seed yield of 1318.33 and 1457.48 kg ha-1, Production efficiency of Seed (10.99 and 12.15 kg ha-1 day-1), economic efficiency (Rs. 291.81 and 501.44 ha-1day-1), partial factor productivity of N and K (74.17 and 81.89 kg ha-1) and P (24.72 and 27.30 kg ha-1) over rest of the irrigation scheduling. Hand weeding twice registered higher seed yield (1719.56 and 1969.24 kg ha-1), Production efficiency of seed (14.33 and 16.41 kg ha-1 day-1), economic efficiency (Rs. 419.52 and 727.18 ha-1 day-1), partial factor productivity of N and K (85.98 and 98.46kg ha-1) and P (28.66 and 32.82 kg ha-1) over weedy check and pendimethalin @1.0 kg a.i.ha-1 PE but economic efficiency with pendimethalin @1.0 kg a.i.ha-1 PE (Rs. 413 ha-1day-1) was at par to hand weeding twice.
