Abstract

This study aims to determine the effect of Sarana Tani Utama (STU) fertilizer on the growth and production of elephant grass (Pennisetum purpureum) cv. Taiwan is grown on a dairy farm in Sipora Jaya, Mentawai Islands. The study used a randomized block design with 5 treatments P0 = 100% fertilizer N, P, and K, P1 = 100% fertilizer N, P, and K + manure, P2 = STU fertilizer + manure, P3 = STU fertilizer, and P4 = STU Fertilizer + Manure + N, P and K Fertilizer and 4 replicates. The results showed that the application of fertilizer doses of N, P, and K + STU gave results that were not significantly different (P>0.05) on leaf length, leaf width, stem diameter, and the effect was very significant (P>0.01) on plant height, number of tillers, yields production, dry matter production, and Revenue Cost Ratio. Plant height ranged from 150.40 – 200.85 cm, leaf length 82.31 – 94.26 cm, leaf width 2.38 – 2.91 cm, number of tillers 3.53 – 5.93 stems, diameter stems 1.60 – 1.78 cm, yield production 8.54 – 21.22 tons/ha, dry matter production 1.49 – 4.52 tons/ha, and RCR 0.58 – 1.32, respectively. From the study results, it could be concluded that the P3 (STU fertilizer) treatment was proven to reduce the use of N, P, and K fertilizers by up to 50%.
