Annual 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, IRCT 413, and Sri Sumrong 60 (SSR 60), respectively. The maximum income was obtained from glutinous corn grown as sole crop with spacing of 0.5*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.
