Water and nutritional supply and soil texture are some of the challenges that affect forage productivity. Therefore, the objective of this work was to evaluate the agronomic performance of Urochloa brizantha cv. Marandu cultivated in clayey and sandy soil submitted to water and nutritional management, in the municipality of Rio Verde, Goiás. The treatments consisted of a combination of soil with two textural classes, two levels of fertilization and seven water depths. The culture performance was evaluated through chlorophyll, plant height, leaf length, leaf width, leaf/stem, crude protein, neutral detergent fiber and dry matter. The data were prepared using multivariate data analysis. Through the analysis of main components, it was possible to observe that the first main component explained 68.94% of the data, being characterized by promoting the best performance of the culture in relation to leaf length and width, characteristics that reflect in the other variables analyzed. The forage presents low performance in winter due to the limitation of climatic conditions. There was a higher yield in the production of dry matter submitted to layers greater than 100% of ETc, regardless of the soil texture and the level of fertilization.
