Macro minerals (Ca, P, Mg and K) concentration mixed of elephant grass (Pennisetum purpureum) CV. Taiwan and Legume Indigofera zollingeriana

Abstract

This study aims to determine the content of macro minerals (Ca, P, Mg and K) of Elephant grass CV. Taiwan and Legumes of Indigofera zollingeriana are grown mixed with different doses of N fertilizer on land that was given Fungi Mycorrhizae of Arbuskula (FMA). This research was conducted by planting grass and Indigofera in the land by different N fertilizer: 0% N, 25% N, 50% N, 75% N. The measured parameters are macro mineral contents of Ca, P, Mg and K. Statistical Analysis calculated by the method of randomized block design with 4 treatments and 3 replications. The results showed that the treatment effect is not significant (P> 0.05) on the content of macro minerals (Ca, P, Mg and K) of elephant grass CV. Taiwan and Legume Indigofera. The mineral content of elephant grass CV. Taiwan ranged from of Ca: 5.6 to 6.6, P: 3.2 to 3.6, Mg: 2.9 to 3.5, K: 5.0 to 5.8 g/Kg DM, respectively. While, macro minerals of legume Indigofera was ranged from of Ca: 4.1 to 4.9, P: 4.0 to 4.3, Mg: 2.8 to 3.0, K: 4.4 to 5.4 g/Kg DM, respectively. From the results of this study concluded that different doses of fertilizer N up to a dose of 75% gives the same result by giving N 0% to macro mineral (Ca, P, Mg and K) of elephant grass CV. Taiwan and Legume Indigofera.
