Abstract

The results of the experiment conducted during 1982-1983 revealed that in the cropping systems, the maximum amount of energy flow was through irrigation (55%) followed by fertilizer (28.5%). The high intensity cropping system viz., sorghum-sorghum ratoon-maize-sunflower with itercrops gave the highest energy input, output and energy efficiency than conventional system. Energy efficiency improved by incorporation of biodigested slurry and inoculation of Azospirillum, under moderate level of N. Irrespective of the cropping systems, application of biodigested slurry at 10 t/ha with 75% recommended N + Azospirillum to each crop needed less specific energy.
