MILHO DOCE CULTIVADO EM SUCESSÃO A DIFERENTES PLANTAS DE COBERTURA

Abstract

The decrease in productivity of agricultural soils has been attributed mainly to inadequate soil management and water erosion. Thus, this study aimed to evaluate the incorporation of conservationist systems in the agricultural production process, which assumes fundamental importance in the practices choice that aim to minimize soil degradation. A practice that has stood out is the management and use of roofing plants The experiment was conducted at the Tarumã farm, located in the municipality of Itumbiara-GO, at an average altitude of 479 m. The design was in randomized blocks, consisting of seven treatments: Control (conventional without straw), Crotalaria spectabilis, Millet. Brachiaria ruziziensis, Crotalaria spectabilis + Brachiaria ruziziensis, Crotalaria spectabilis + Millet, Crotalaria spectabilis + Brachiaria ruziziensis + Millet, with four repetitions. The experiment was carried out from November 2018 to March 2019. The data obtained were submitted to analysis of variance by the F test according to the experimental design adopted. The averages were compared using the Tukey test at 5% probability. It is concluded that, there was interaction among Nitrogen and Potassium, nutrients easily leached, and of great mobility in the soil and in the plant. Providing greater productivity compared to the use of different coverings, highlighting the use of Crotalaria spectabilis + Brachiaria ruziziensis + Millet and Crotalaria spectabilis + Brachiaria ruziziensis.
