Perubahan Sifat Kimia Gambut Pedalaman Akibat Pemberian Dolomit dan Pupuk Majemuk Hayati dan Hasil Tanaman Kedelai Edamame (Glycine max (L.) Merrill)

The purpose of this study was to study the effect of dolomite and compound biofertilizer on changes in the chemical properties of peat and edamame plant yields on inland peat. Using a Factorial Completely Randomized Design with 2 factors. The first factor is dolomite lime with 4 levels, namely D0 = 0 t ha-1, D1 = 5 t ha-1, D2 = 10 t ha-1, D3 = 15 t ha-1 and the second factor is compound biofertilizer with 4 levels, namely H0 = 0 g.kg-1 seed, H1 = 5 g.kg-1 seed, H2 = 10 g.kg-1 seed, H3 = 15 g.kg-1 seed. The results of the study showed that increasing the dose of dolomite to 15 t ha-1 together with the provision of biofertilizer at a dose of 10 or 15 g.kg-1 of seed was able to provide the highest pH value, namely 4.06 - 4.18. In the parameter of peat total N value, only dolomite treatment gave a significant difference. The highest average Ca-dd value was obtained by addition 15 t ha-1 of dolomite together with biofertilizer at a dose of 15 g.kg-1 of seed, which was 14.897 (gmol(+)/kg). The highest Mg-dd value was obtained by addition 15 t ha-1 of dolomite together with biofertilizer at a dose of 15 g.kg-1 of seed, which was 36.680 (gmol(+)/kg). The highest number of pods (25.00 pods) and the highest pod weight (11.12 g) were obtained by addition 10 t ha-1 of dolomite. The highest number of pods occurred by biofertilizer at 15 g.kg-1 of seed (21.70 pods).
