Desenvolvimento e produtividade dos capins mombaça e marandu cultivadas em dois solos típicos do Tocantins com diferentes regimes hídricos

The objective of this study was to evaluate the productive and agronomic parameters of Panicum maximum cv. Mombaca and the Brachiaria brizanta cv. Marandu grown in Oxisoil, and Entsoil under different water schemes. The experiment was conducted in a greenhouse in EMVZ - School of Veterinary Medicine and Zootecnia / Federal University of Tocantins, campus of Araguaina, TO. The completely randomized design in a factorial arrangement (2x4x2), which consisted of two forage species, four levels of water (25%, 50%, 75% and 100% of the capacity of field), two types of soils, with four repetitions, making 62 experimental units. The production of dry mass of Forage (MSF) was linear behavior increasing in line with the increase in the percentage of moisture, for the two cultivars in two production cycles, the two types of soil, being that the clay soil in both cultivars returned relative superiority in comparison with the sandy soil. The mean width of leaves are not differentiated (P>0.05) in three major schemes in two cultivars. The same is observed for size of leaves to Mombaca grass, and for the two major Marandu. There was no (P> 0.05) for comparing stem diameter of the largest schemes. In the measures of time it was observed that plants were higher humidity in two largest (P
