Abstract

Growth and productivity of forage plants are dependent on organic compounds stored in the plants and can be affected by zinc nutrition. Faced applicable, it was aimed to evaluate the effect of zinc fertilizer in the metabolic compounds tanzania grass and palisadegrass. The experiment was realized in greenhouse in pots filled with 3 dm3 of medium texture Oxisol with five plants. The experimental design was completely randomized in factorial scheme 2x3 (two grasses: Panicum maximum cv. Tanzania and Brachiaria brizantha cv. Marandu, and three zinc rates: 0, 60 and 240 mg dm-3) with four replicates. There were difference between cultivars for all variables, except for free aminoacids and nitrate. However, the increase in Zn rates did not promote difference in the organic compounds of the plants. The application of Zn did not affect the synthesis of metabolites components tanzaniagrass and palisadegrass. The tanzania grass had higher uptake of Zn and N, and higher capacity for synthesis of soluble carbohydrates and crude protein than palisadegrass, showing higher biomass yield.
