Abstract
The dominant cropping system of rice-wheat (covering 10.5 million hectares) is widely adopted by the farmers of the Indo-Gangetic Plains Region of India, which accounts for 25% and 40% of the total area under rice and wheat, respectively. The yield stagnation of both the crops is due to the monotony of the system, the over exhaustive nature of cereal-cereal crop sequences, and the huge over-exploitation of the natural resource base. Other high value and volume crops can effectively be included in the system replacing wheat, while promoting sustainability and profitability of the system. Results showed that rice (Oryza sativa L.)- potato (Solanum tuberosum L.)- onion (Allium cepa L.) and rice-potato-japanese mint (Mentha arvensis L.) crop sequences are statistically at par with each other, produced a significantly higher rice equivalent yield of 288.80 q ha−1 and 266.40 q ha−1, respectively than that obtained under rice–potato–green gram (Vigna radiata L.) (193 qha−1), rice–frenchbean (Phaseolus vulgaris L.)–Japanese mint (173.5 qha−1), rice-mustard (Brassica compestris L.)–Japanese mint(167.4 qha−1), rice-lentil (Lens esculenta L.)–japanese mint (161.0 qha−1) and rice–wheat (Triticum aestivum L. emend. Fiori & Paol.)–japanese mint (which is the most common farmers' practice) (142.0 q ha−1) crop sequences. The rice-potato-japanese mint and rice–potato–onion crop sequences are more productive and economically viable as they also fetched more net returns per unit area for time invested, and can be a better option for the farmers of the Central Plains Zone of India. These two cropping sequences were also judged as most sustainable by the farmers in their local agricultural production system.
