Efeito de diferentes doses e formas de aplicação de boro sobre a produção de forragem de trevo vesiculoso

Abstract

The northwestern region of the brazilian state of Rio Grande do Sul features the milk production as one of the main economic activities, and the most part is based on the pasture diet, turning the activity more profitable than the other systems and enabling the activity. In this context, it highlights the importance of the productive aspects that guide the pastures of this region, both nutritional as management aspects. It’s nearly a consensus among forage researches when it comes to the relevance of winter legumes to the productive processes, especially the Trifolium genus (general clovers), mostly for their good palatability, great nutritional potential and for being one alternative to increase native fields and nitrogen fixation in soil capacity. However, even with all these qualities, the clover has not been often used on pastures of Rio Grande do Sul state, in parts because of the rough establishment and for the fact that clover nutritional demand still is not well known, bringing uncertainty to the management. Therefore, this work aims the evaluation of clover (Trifolium vesiculosum Savi) dry mass production exposed to different doses of boron and two application forms. The experiment will be conducted in the field of the South frontier federal university – Cerro largo campus (UFFS) experimental area under randomized delineation with two-way factorial treatment arrangement (5x2x3), five doses of boron (0 kg; 1 kg; 2 kg; 3 kg e 4 kg) two forms of application (on soil or leaves) and three repetitions.
