Diversification of cropping systems under assured irrigated conditions in central plateau zone of Maharashtra

摘要

A field experiment was conducted for three consecutive years (2005-2007) at Parbhani to find out most productive and profitable cropping system. Among the different cropping systems, highest wheat [(Triticum aestivum (L.) emend. Fiori & Paol] equivalent yield (19.9 t/ha) and net monetary returns ((sic)107.8x10(3)/ha) were obtained from soybean [Glycine max (L. Merr.)]-onion (A/hum capa L.) cropping system, followed by turmeric (Curcuma domestica L.)+ castor (Ricinus communis L.) (WEY-14.0 t/ha, and NMR (sic)89.8x10(3)/ha). The soybean onion system also recorded maximum net monetary advantage per unit time ((sic)573/ha/day), employment (374 mandays) and water use efficiency (221 kg/ha-cm), followed by turmeric+castor intercropping system. The highest nutrient uptake was recorded in sorghum [Sorghum bicolor (L.) Moench]-wheat followed by maize (Zea mays L.) + cowpea (Vigna sinensis L.) wheat and maize wheat cropping systems. The highest soil nutrient status was observed in cotton (Gossypium sp.)-summer groundnut (Arachis hypogaea L.) followed by soybean onion cropping systems.
