Kandungan NDF dan ADF Rumput Gajah Mini (Pannisetum purpureum CV. Mott) di Dataran Tinggi Tor Simarsayang dengan Penggunaan Dosis Pupuk Nitrogen Bervariasi

Abstract

The research aims to determine the effect of Nitrogen fertilizer dosage on the content of Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) of Mini Elephant grass (Pennisetum purpureum CV. Mott) planted on the Tor Simarsayang plateau. The research was carried out in January-February at Tor Simarsayang, Faculty of Agriculture, Graha Nusantara University, Padangsidimpuan. The research was designed using a Completely Randomized Design (CRD) consisting of 4 treatments, namely: 0 kg N/ha (P0) as a control, the second treatment was 100 kg N/ha (P1), the third treatment was 200 kg N/ha (P2), and the fourth treatment was 300 kg N/ha (P3), each treatment was repeated 4 times. The variables observed were the NDF and ADF content of Mini Elephant Grass. The data obtained were analyzed using analysis of variance (ANOVA). The research results showed that the use of nitrogen fertilizer reduced the NDF and ADF content of elephant grass. It was concluded that applying nitrogen fertilizer at a dose of 300 kg N/ha gave the best results on the NDF and ADF content of Mini Elephant Grass.
