| Abstract | ||||
| Prices of mineral fertilizers are getting higher nowadays, so that this experiment was designed. In a private farm in the New Vally governorate, different fertilizer combinations; organic, bio and mineral sources were used in this study to grow potato (Cara cv.) in sand soil in the two following winters of the years 2019/2020 and 2020/2021. Results showed that inoculating potato plants with Biofert (as N-fixing bacteria) in the presence of organic manures ―half of the recommended doses‖ (as FYM + PM) gave the highest mean values of all studied growth and yield characters. When compared to plants grown with the control treatment, potato plants treated with FYM + PM + Biofert + 100% NPK dosage had the greatest mean values for those features. The increased amount of soluble nutritional components in mineral fertilization made it more impactive than organic manures or biofertilization in terms of improving soil fertility. The yield and quality indicators of potato tubers increased as a result of this impact. From the obtained results, it could be recommended that inoculating potato plants with the Biofert (as N-fixing bacteria) and Biopotass (as K-solubilizing bacteria) combined with compost (FYM) + (PM) and 75% of the recommended doses of mineral fertilization (NPK) is the best for potato production to get the highest economic yield of potato with the best qualities of marketable tubers. | ||||
