Abstract

The objective was to evaluate increasing doses of lime associated with nitrogen fertilization on the agronomic and bromatological characteristics of Marandu grass. The experimental design was a randomized block design (DBC) in a 5x2 factorial scheme, with five levels of dolomitic limestone (0; 2; 4; 6 and 8 t ha-¹) in the presence and absence of nitrogen fertilizer (controlled release urea). under cover (250 kg ha-¹), with four repetitions. Agronomic characteristics (plant height, number of tillers and productivity), bromatological parameters (crude protein (CP), neutral (NDF) and acid detergent fiber (ADF), lignin, cellulose and hemicellulose) and macronutrient contents (N, P, K, Ca, Mg, and S) and micronutrients (B, Cu, Mn, Zn, and Fe) of plants. There were significant changes in production, nutrient content and bromatological parameters of the crop. Lime doses of 2 to 4 t ha-1 associated with nitrogen fertilization increased productivity, the number of tillers, CP (%) and the contents of nutrients N, P, K, Ca, Mg and S and reduced the NDF (%), ADF (%) and Fe and Mn contents in forage. Nutrient extraction decreased in the following order: K > N > Ca > Mg > P > S. The use of higher dosages of limestone negatively affected the analyzed variables.
