The potential of the legume types in the quality and economic value of Nitrogen of Setaria anceps Stapf

Abstract

Abstract The study aimed to identify the effect of legume types on the biomass, protein content, and economic value of nitrogen in Setaria ancpes Stapf and legume intercropping. The research site was in Makassar. This study employed Completely Randomized Design consisting of 5 groups. The experimental land area of 408 m2 (17 x 24m) was divided into 25 plots (each 3 x 4 m). The used forages in this study were Setaria ancpes Stapf, Centrosema pubescens, Clitoria ternatea and Dioclea quanensis. The treatments in this study were L0: Setaria ancpes Stapf; L1: Setaria ancpes Stapf + Centrosema pubscens; L2: Setaria ancpes Stapf + Clitoria ternatea; L3: Setaria ancpes Stapf + Dicolea quanensis; L4: Urea fertilizer (20 kg N/ha). The study indicated the legume-grass intercropping in Setaria ancpes Stapf may result in the increased protein content and forage biomass. Clitoria ternatea contributed higher economic value of nitrogen compared to Centrosema pubescens and Dioclea quanensis.
