Yield, Agronomic Characteristics and Chemical Composition of Silage Fodder (Sorghum bicolor L.) With and Without Fertilization.

Abstract

Objective: To evaluate the yield and structural characteristics of sorghum fodder, as well as the chemical quality of the fodder and the silage with and without fertilization. Design/Methodology/Approach: The evaluated variables were, in the fodder: dry matter yield (DMY, kg ha1 ), leaf:stalk ratio (L:S, g g1 ), plant height (H, cm) and intercepted radiation (IR, %); and in the silage: dry matter (DM, %) crude protein (CP, %), neutral detergent fiber (NDF, %), acid detergent fiber (ADF, %), lactic acid (LA, %) and pH. There were two treatments, with fertilization and without fertilization.
