Abstract

The role of N, Zn and Fe on the synthesis and accumulation of protein and also the concentration of P and Ca in the forage at different age of BN 2 grass was studied. The crude protein content was significantly increased from 8.41 to 9.90 per cent with the addition of 150 kg N/ha. Application of 5.0 kg ZnSO, increased the protein content from 8.95 to 9 65 per cent. The concentration of both P and Ca were increased with every increment of N, while these were not affected by Zn and Fe applications. Higher amounts of crude protein, P and Ca were noticed in the initial stages of the growth and gradually decreased with advancement in the age of the crop.
