Abstract

Assessing the nutrient release by cover crops species, especially those used in green manure, is important for planning activities aimed at the higher economic return. The use of these species in order to improve the growing conditions in the transition region between the Cerrado and Pantanal biomes, which have particular characteristics, may be a viable alternative. This study aimed to evaluate the amount of biomass produced and macronutrients released in this biomass by different green manure species grown in the Cerrado/Pantanal ecotone. The trial was carried out from April 2013 to June 2014 in the Plant Science sector at State University of Mato Grosso do Sul, Aquidauana-MS (Brazil). Experimental design was completely randomized arranged in time split plot, with four replications. First factor consisted of seven species of green manure, while the second were seven evaluation times (months). The variables evaluated were: dry mass of shoot and nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) contents as a function of time. For all variables evaluated there was significant interaction between the green manure species and the collection months. Vegetable cover showed different rates of decomposition and nutrient release. Mucuna aterrima was the species that produced higher amounts of dry mass and nutrient content. After four months of cutting the plants, green manure species do not differentiate between the amounts of released nutrients.
