| Abstract | |
Aiming to evaluate the effects of different organic compost rates in chemical properties of soil cultivated with banana plants 'Prata-anã' (Musa AAB), this present work was carried out at "Faculdade de Ciências Agronômicas - UNESP", Botucatu-SP. Plants were placed in the prepared area in November 2002, at 2,5 x 2,5 m spacing between plants. The organic compost was produced using wood residue and bovine manure and the treatments were constituted by different compost rates: T1 = 0 g plant-1 of K2O (zero of compost); T2 = 98,5 g plant-1 of K2O (43 kg plant-1 of compost); T3 = 197,0 g plant-1 of K2O (86 kg plant-1 of compost); T4 = 290,5 g plant-1 of K2O (129 kg plant-1 of compost); T5 = 394,0 g plant-1 of K2O (172 kg plant-1 of compost). Rates were calculated based on the amount of potassium contained in the compost. The experiment was arranged in a randomized block design, with 5 treatments, 5 replications and 2 plants per plot. Data were submitted to variance analysis and to regression analysis. Four months after the last compost application, the soil was sampled at 20 cm deep and the chemical properties of the soil were evaluated. The organic fertilization increased pH, organic matter, phosphorus, calcium, the sum of bases, CTC, and the base saturation of the soil. (AU) | |
