 หัวเรื่อง:การเพิ่มรายได้สู่ระบบการปลูกข้าวโพด-ฝ้ายโดยการเพิ่มพืชแซม ผู้เขียน: Nopporn Sayampol, Sodsai Changsalak สื่อสิ่งพิมพ์:pdf AbstractTable 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. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Add Peanut to Corn-Cotton Relay Cropping System) ผู้เขียน:Nopporn Sayampol, Sodsai Changsalak สื่อสิ่งพิมพ์:pdf AbstractAnnual crops, soybean, vegetable soybean, mungbean, peanut and sesame were tried as double crops with corn or cotton or both in typical corn-cotton relay cropping system of Kanchanaburi province, where spacing between rows for corn and cotton were wider than recommended for sole crop. During 1994-1996 experiments, row and hill spacing and number of plants per hill of corn, cotton and short annual crops were varied in order to find suitable cropping systems, which gave maximum net income. Cotton varieties used in 1994, 1995 and 1996 were IRCT 413, IRCT413 and Sri Sumrong 60 (SSR 60), respectively. The maximum income was obtained from glutinous corn grown as sole crop with spacing of 0.5 x 0.25 m, one plant per hill, followed by double planting of one row of SSR 60 and 3 row of peanut, with spacing of 1.5 m between cotton rows. Optimum spacing between hills of cotton was 0.5 m with two plants per hill, while spacing between hills of peanut was 12.5 cm with two plants per hill. |
