Abstract: A field experiment was conducted during rabi seasons of 2010-11 and 2011-12 at the Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh to assess the effect of different tillage and weed management practices on energetics and economics of chickpea-soybean cropping sequence. The treatments were divided into main and sub plots (tillage and weed management practices). Three tillage practices viz. conventional tillage (T1), minimum tillage (T2) and zero tillage (T3) in main plot and nine weed management practices as pendimethalin @ 1000 g ha-1 PE (W1), imazethapyr @ 80 g ha-1PE (W2), imazethapyr @ 90 g ha-1 PE (W3), imazethapyr @ 100 g ha-1 PE (W4) at 2 DAS, imazethapyr @ 70 g ha-1 POE (W5), imazethapyr @ 80 g ha-1 POE (W6), imazethapyr @ 90 g ha-1 POE (W7) at 20 DAS, one hand weeding at 20 DAS (W8) and weedy check (W9), in sub plots. Among the various tillage practices maximum energy use efficiency 6.22 q MJ-1 × 10-3 ha-1 and energy productivity 265.32 kg MJ-1 ha-1 were obtained with conventional tillage (T1) followed by minimum tillage (T2) and zero tillage (T3) and among the different weed control methods maximum energy use efficiency 9.59 q MJ-1 × 10-3 ha-1 and energy productivity 388.95 kg MJ-1 ha-1 were found with one hand weeding at 20 DAS (W8) followed by post-emergence application of imazethapyr @ 90 g ha-1 (W7) followed by imazethapyr @ 80 g ha-1 PoE (W6). The economic production of experiment in terms of net return was maximum under (T1) conventional tillage Rs.43800.38 ha-1 ha-1 with B:C ratio 2.62 and (W8) one hand weeding at 20 DAS Rs. 45524.27 ha-1 with B:C ratio 2.24 and this was followed by @ 90 g ha-1 imazethapyr, where net return Rs.44055.83ha-1 and B:C ratio 2.41. The minimum net return and B:C ratio was observed under zero tillage (T3) and weedy check (W9).
