Increasing Profit to Maize-Cotton Planting System with Intercrop

Abstract

Table corn and baby corn were grown in early rainy season, 1993, at The National Corn and Sorghum Research Center, Nakhon Ratchasima Province with row spacing of 1.5 meters, and intercropped with one row of peanut or sesame. Two cotton varieties, IRCT413 and Si Samrong 60, were planted 1 week relay to corn harvest. The result indicated that cropping systems with table corn gave more profit than that of the baby corn. In the system of table corn with peanut, peanut yielded satisfactory profit, while the income from sesame was less than investation. Seed cotton of Si Samrong 60 gave more profit than IRCT413. In another experiment, two rows of peanut or sesame were intercropped with these two cotton varieties planted with row spacing of 1.5 meters, on 30th, June, 1993. The result showed that intercropped peanut and sesame had no effect on cotton yield reduction, and peanut gave satisfactory profit, while the income from sesame was less than investation, similary to the former experiment.
