摘要

A field experiment was conducted during 2005-06 and 2006-07 at Varanasi, Uttar Pradesh, to find out the effect of organic nitrogen sources and biofertilizers on system productivity and energy budgeting of rice (Oryza sativa L.)-based cropping system. Rice-potato [Solanum tubersoum (L.)]-onion [Allium cepa (L.)] system recorded significantly higher production efficiency (97.5 kg/ha/day), land-utilization efficiency (91.4%), economic efficiency (738/ha/day), energy input (61.08x103 MJ/ha) and energy output (187.09x103 MJ/ha). The lowest (39.4x103 MJ/ha) energy intensiveness was recorded in rice-table pea (Pisum sativum var. hortense)-cowpea [Vigna unguiculata (L.) Walp.] cropping system. However, the organic nutrition with biofertilizers (Azotobacter and phosphate-solubilizing bacteria) had the highest rice-equivalent grain yield (35.3 t/ha), production efficiency (96.7 kg/ha/day), land utilization efficiency (89.8%), economic efficiency (803 ha/day) and energy-use efficiency (3.15) of system, followed by organic nitrogen sources alone (3.0). Recommended dose of N @100% through organic nitrogen sources alone was the next best treatment resulting in higher productivity and system efficiency. Rice-potato-onion cropping system was found most productive, profitable and energy efficient with application of 100% recommended dose of nitrogen through organic sources along with biofertilizers.
