Abstract:

An on-farm experiment on crop diversification and substitution of rainy season rice in Kamakhyanagar in Dhenkanal District, Orissa, India was conducted to improve the economic conditions of the farmers and to increase rain water utilization efficiency and cropping intensity through appropriate cropping pattern. Six crops, viz., rice (Oryza sativa), groundnut (Arachis hypogaea), pigeonpea (Cajanus cajan), cowpea (Vigna unguiculata), maize (Zea mays) and black gram (Phaseolus mungo [V. mungo]), were grown in the first week of June 200. To increase the cropping intensity after harvesting of the rainy season crops, sesame (Sesamum indicum) and horse gram (Macrotyloma uniflorum) were grown utilizing moisture and retreating monsoon rainfall. Results showed that instead of rice, other low water-requiring crops like maize, groundnut, pigeonpea, and black gram have good economic return even in drought affected years. Farmers also sold maize cobs and got very good economic returns even under severely drought affected year. Planting of horse gram and sesame also resulted to a reasonable yield.
