The results from this study indicated that percentages of N. P , K , Mg and Calcium were increased in potato leaves by reducing the mineral fertilizer of the recommended dose (300 kg rock phosphate and 150 kg N and 175 kg K20) to half or quarter with bio fertilizer. Using biofertilizer with half or quarter of recommended dose of mineral fertilizer caused increasing in specific gravity of potato tuber. Adding biofertilizer alone increased dry matter content in potato tuber UR - http://nile.enal.sci.eg/EALE/2002/EJH/2902/1/99.pdf ER -
