Culturas intercalares em lavouras cafeeiras
Two field experiments were conducted during 1975 to 1979 using young and mature pruned coffee plants. The study intended a more rational growing of crop species interrow with coffee plants. In the young coffee plants experiment the following crop species were used: cotton IAC 13-1 (3, 2, 2), rice IAC-25 (4, 3, 3), dry beans Carioca (4, 3, 3), corn HMD-7974 (2, 2, 1) and soybean Paraná (4, 3, 3) and in the pruned mature coffee plants experiment the species used were: rice IAC-1246 (5, 3, 3, 3), rice IAC-Batatais (5, 3, 3, 3), dry beans Carioca (5, 3, 3, 3), dry beans Moruna (5, 3, 3, 3), corn Cargill-111 (2, 1, 1, 1), corn Piranao (2, 1, 1, 1), soybeans Paraná (5, 3, 3, 3) and soybeans Vicoja (5, 3, 3, 3). The number of rows of crop species intercropped with coffee tree in the first, second, third and fourth years are respectively pointed out in the parenthesis. The taller crops like corn and mainly cotton were those which most affected the development and production of the coffee plants. The degree of competition between intercropped species and coffee plants was shown in their production as follows: rice major dry beans major soybeans major corn major cotton, suggesting that cotton may not be planted intercropped with young coffee plants. Large quantities of nutrients were removed by the intercropped species residues contributing this way for soil degradation, although any king of nutritional problem was detected by chemical analysis in the plants coffee during the work
