Effect of Application of Compost With Inorganic Fertilizer on Population of Phosphate-Solubilizing Bacteria and Maize Yield in Dry Land

The aim of this study was to explore the effect a combination manure and inorganic fertilizer (NPK Urea) on population phosphate-solubilizing bacteria yield maize. carried out from June October 2018 in Kemantren Village, Alas Kulak Hamlet, Jabung District, Malang Regency. This used randomized block design consisting 8 treatment levels repeated three times. results analysis variance showed that application compost, gave significantly different phosphate solubilizing C-organic, P-total, P-available, dry shelled weight stover weight. 2 t ha-1 compost + 100 kg NPK 50 highest for with value 61×104 CFU.g-1. Maize production yields obtained 400kg.ha-1NPK 200 kg.ha-1 Urea reached 8.65 ha-1.
