      Abstract
      Indigofera zollingeriana merupakan tanaman legum hijauan pakan ternak yang mampu tumbuh di daerah marginal, termasuk lahan bekas tambang batu bara. Penelitian ini bertujuan mengevaluasi pemberian pupuk Triple Super Phosphate (TSP), pupuk rock phosphate (RF), dan Fungi Mikoriza Arbuskular (FMA) terhadap pertumbuhan dan produksi Indigofera zollingeriana di lahan bekas tambang batubara. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial dengan faktor pertama yaitu kombinasi pupuk TSP dan rock phosphate (RF) yang terdiri dari A0 (100% TSP;0% RF), A1 (75% TSP;25% RF), A2 (50% TSP;50% RF), A3 (25% TSP;75% RF), A4 (0% TSP;100% RF) serta faktor kedua yaitu dosis FMA yang terdiri dari B0 (Tanpa FMA), B1 (20 g FMA). Data yang diperoleh dianalisis menggunakan ANOVA dengan uji lanjut Duncan dan uji T. Hasil penelitian menunjukkan bahwa interaksi pupuk TSP dan RF dengan FMA tidak signifikan (P > 0,05) terhadap pertumbuhan vegetatif I. zollingeriana. Akan tetapi, pemberian dosis FMA berpengaruh sangat nyata (P < 0,01) terhadap produksi biomassa dan kolonisasi akar. Simpulan penelitian ini yaitu kombinasi pupuk TSP dan RF kurang efektif meningkatkan pertumbuhan dan produksi biomassa tanaman I. zollingeriana, akan tetapi pemberian FMA mampu meningkatkan produksi biomassa dan kolonisasi akar tanaman I. zollingeriana. Kombinasi pupuk TSP dan RF dari perlakuan A1 (75% TSP; 25% RF) menunjukkan hasil terbaik pada tinggi tanaman I. zollingeriana. Indigofera zollingeriana is a leguminous plant with high potential as forage for livestock and the ability to grow in marginal lands. This study aims to evaluate the effectiveness of Triple Super Phosphate (TSP) fertilizer, rock phosphate (RF), and Arbuscular Mycorrhizal Fungi (AMF) on the productivity of Indigofera zollingeriana cultivated on former coal mining land. The research employed a factorial Completely Randomized Design (CRD) with two factors. The first factor was the combination of TSP and RF fertilizers: A0 (100% TSP:0% RF), A1 (75% TSP:25% RF), A2 (50% TSP:50% RF), A3 (25% TSP:75% RF), and A4 (0% TSP:100% RF). The second factor was the AMF dose: B0 (no AMF) and B1 (20 g AMF). Data were analyzed using ANOVA followed by Duncan’s multiple range test and T-Test. The results showed that the interaction of TSP and RF fertilizers with AMF was not significant (P > 0.05) on the vegetative growth of I. zollingeriana. However, AMF dosing had a very significant effect (P < 0.01) on biomass production and root colonization. The conclusion of this study is that the combination of TSP and RF fertilizers is less effective in increasing the growth and biomass production of I. zollingeriana plants, but the application of AMF can increase biomass production and root colonization of I. zollingeriana plants. The combination of TSP and RF fertilizers from treatment A1 (75% TSP; 25% RF) showed the best results on plant height of I. zollingeriana.
