Abstract

THE EFFECT OF N-P-K FERTILIZER ON THE YIELD OF DRY MATTER AND CRUDE PROTEIN OF GRASS (Brachiaria humidicola cv. Tully and Pennisetum purpureum cv. Mott.). This research was done to evaluate the effect of macro elements N-P-K on the dry matter and crude protein yield of grass (Brachiaria humidicola cv. Tully and Pennisetum purpureum cv. Mott). The research used combination of N-P-K fertilizer. The treatments were arranged in factorial design based on the Completely Randomized Design with two factors, three treatments and four replications. The factor A was applied for testing different grass of Brachiaria humidicola cv. Tully (a1), and Pennisetum purpureum cv. Mott (a2). The factor B was fertilizer combination of N (b1), NP (b2), and NPK (b3). Variables observed were dry matter and crude protein. The results of variance analysis showed that treatment affected significantly (P <0.05) dry matter and crude protein. Application of factor A indicated that both grasses had positively response to the application of N-P-K fertilizer measured on the yield of dry matter and crude protein. Keywords: N-P-K Fertilizer, Dry Matter, Protein, Brachiaria humidicola cv. Tully and Pennisetum purpureum cv. Mott.
