| dc.description.abstract | ABSTRACT The present investigation entitled “Production potential and economic viability of food-forage based cropping sequence under irrigated conditions of Jabalpur (M.P.)” was conducted at AICRP on forage crops, JNKVV, Jabalpur (M.P.). The experiment was conducted in randomized block design replicated three times with 10 food-forage based cropping sequences viz., hybrid napier + ricebean – hybrid napier + berseem – hybrid napier + ricebean, maize (baby corn) + ricebean – berseem – maize (baby corn) + ricebean, maize (baby corn) + ricbebean – oat – maize (baby corn) + ricebean, maize (baby corn) + ricebean – berseem – maize (fodder) + ricebean, maize (baby corn) + ricebean – oat – maize (fodder) + ricebean, maize (green cob) + ricebean – berseem – maize (green cob) + ricebean, maize (green cob) + ricbean – oat – maize (green cob) + ricbean, maize (green cob) + ricbean – berseem – maize (fodder) + ricbean, maize (green cob) + ricbean – oat – maize (fodder) + ricebean and rice – berseem – moong. The salient findings of the investigation are briefly summarized as below - Productivity of the cropping system Among ten crop sequences tested maize (baby corn) + ricebean – berseem – maize (baby corn) + ricebean cropping sequence led to record the maximum productivity (2842.37 q/ha/year) in terms of maize green fodder equivalent yield as well as production efficiency of (11.34 q/ha/day). Hybrid napier + ricebean – hybrid napier + berseem – hybrid napier + ricebean obtained minimum maize green fodder equivalent yield (1371.37 q/ha/year) and production efficiency of (4.22 q/ha/year), but it recorded maximum (88.89%) LUE. Maize (baby corn) + ricebean – oat – maize (baby corn) crop sequence registered minimum (57.94%) LUE. Total dry matter, crude protein and crude fibre yield Total dry matter yield was found maximum under (357.88 q/ha) and minimum in crop sequence (244.97 q/ha). Total crude protein yield was recorded highest in crop sequence of maize (green cob) + ricebean – berseem – maize (fodder) + ricebean (40.26 q/ha) whereas lowest in rice – berseem – moong (23.60 q/ha) crop sequence. In regard to total crude fibre yield, maize (baby corn) + ricebean – oat – maize (fodder) + ricebean crop sequence ranked first among all food-forage based cropping sequence which obtained (103.49 q/ha) crude fibre yield. Perennial grass sequence of hybrid napier + ricebean – hybrid napier + berseem – hybrid napier +| ricebean registered minimum crude fibre yield (71.35 q/ha). Energy budget of the food-forage crop sequence Hybrid napier + ricebean – hybrid napier + berseem – hybrid napier + ricebean crop sequence recorded highest energy use efficiency (31.33 MJ/ha) and minimum output efficiency (1052 MJ/ha). EUE was recorded lowest in the maize (baby corn) + ricebean – oat – maize (baby corn) + ricebean (20.31 MJ/ha). Maximum energy productivity obtained by maize (baby corn) + ricebean – berseem - maize (baby corn) + ricebean (4.61 kg/MJ) but in regard of specific energy it was minimum in this sequence (21.65 MJ/kg). The total energy input requirement was highest in maize (green cob) + ricebean – oat – maize (green cob) and maize (green cob) + ricebean – oat – maize (fodder) + ricebean (64.1 x 103 MJ/ha) crop sequences whereas minimum in perennial grass sequence (36.5 x 103 MJ/ha). But in regard of energy output, it was recorded maximum in maize (green cob) + ricebean – berseem – maize (fodder) + ricebean (65.2 x 103 MJ/ha) crop sequence. The lowest energy output and energy balance were recorded by hybrid napier grass sequence (341 x 103 MJ/ha) and (304 x 103 MJ/ha) respectively. Effect of different food-forage cropping sequence on total uptake and soil fertility status Crop sequence maize (green cob) + ricebean – berseem – maize (fodder) + ricebean recorded the maximum uptake of N (642.1 q/ha) followed by maize (baby corn) + ricebean – berseem – maize (fodder) + ricebean (639.7 q/ha) whereas minimum uptake of N was noted with rice – berseem – moong crop sequence (386.3 q/ha). Total uptake of P was noticed maximum in maize (baby corn) + ricebean – oat – maize (fodder) + ricebean (103.4 q/ha) and minimum in hybrid napier crop sequence (587.9 q/ha). Existing crop sequence rice – berseem – moong registerd (61.2 q/ha) total P uptake. Uptake of K was highest in maize (baby corn) + ricebean – oat – maize (baby corn) + ricebean (757.0 q/ha) and lowest in hybrid napier + ricebean – hybrid napier + berseem – hybrid napier + ricebean (435.9 q/ha). Based on data pertaining to changes in soil properties after completion of 2 crop cycles of various crop sequences were safe to maintain the soil properties. But continuous hybrid napier cropping gave an indication for depletion of OC in the soil after completion of 2 cycles of the rotation. The enhancement in fertility status of soils may be attributed to inclusion of legumes in all crop sequences. Employment generation Hybrid napier + ricebean – hybrid napier + berseem – hybrid napier + ricebean sequence recorded highest employment generation efficiency (0.80 mandays/ha/day). In this regard, maize (baby corn) + ricebean – oat – maize (baby corn) + ricebean crop sequence registered minimum employment generation efficiency (0.54 man days/ha/day).
