| With the objective of studying the effect of increasing phosphorus and potassium doses on the agronomical and technological characteristics of the cotton (Gossypium hirsutum L.), cultivar IAC 20, an experiment was carried out during 1994/95 on a Red-Dark Latossol at the Embrapa-Centro de Pesquisa Agropecuária do Oeste (CPAO) in Ponta Porã, MS, Brazil. A randomized bloch design was used in a 3 x 5 factorial arrangement with four replications. The doses were 30, 60 and 90 kg ha-1 of P2O5, applied as triple superphosphate, and 0, 30, 60, 90 and 120 kg ha-1 of K2O as KCl. The K2O doses used had a significant influence on the seed cotton yield, plant height and weight of 100 seeds and of bolls. |

| The feasibility of no-tillage in the Cerrado (Savanna-like vegetation of Brazil) depends on the production of sufficient above-ground crop residue, which can be increased by corn-forage intercropping. This study evaluated how above-ground crop residue production and yields of soybean and late-season corn in a soybean-corn rotation were influenced by the following crops in the year before soybean: corn (Zea mays L.) intercropped with Brachiaria (Urochloa) brizantha cv. Marandu, B. decumbens cv. Basilisk, B. ruziziensis, cv. comum., Panicummaximum cv. Tanzânia, sunn hemp (Crotalaria juncea L.), pigeon pea [Cajanus cajan (L.) Millsp]; sole corn, forage sorghum [Sorghum bicolor (L.) Moench (cv. Santa Elisa)], and ruzi grass. In March 2005, corn and forage... |
