Abstract

A field experiment comprised of treatments comprising 14 crop sequences were conducted to study the effect of crop diversification in rice (Oryza sativa)–wheat (Triticum aestivum) cropping system on system productivity, economics and soil health. The results revealed that overall productivity of the system in terms of system rice grain equivalent yield was noticed significantly highest in rice-potato-blackgram (28.88 tonnes/ha/yr) compared to rest of the cropping sequences, followed by rice–maize (cob) + veg. pea (1:2) – greengram cropping sequence (25.67 tonnes/ha/yr). In addition to that inclusion of legumes either as green manure crop or grain/fodder legume proved crucial in maintenance of soil bio-physico-chemical properties of the soil. Therefore, diversification of rice–wheat system under irrigated condition by inclusion of moong crop after potato or wheat could enhance the overall productivity and profitability of the farm, besides improving the soil sustainability on long term basis.
