| Abstract | ||||
| Two experiments were carried out during the two successive Summer seasons of 2017and 2018 at Post Harvest Lab. Horticulture Department of Faculty of Agriculture, Benha University, to investigate the effect of two propagation methods (cutting tuber and mini tubers), sources of N fertilizers in either organic and or mineral forms (100% mineral N fertilizer (as recommended dose120 N kg/fed) ; 50% mineral-N + 50% organic-N fertilizers, 25% mineral-N + 75% organic-N fertilizers or 100% organic-N fertilizers) and soil addition with effective microorganisms (EM) at 10%, seaweed extract at 1% and yeast extract at 10% as well as their combinations on storability of potato (Solanum tuberosum L.) cv. Spunta. At harvest time, tubers from each experimental plot were collected and stored after discarding the infected tubers. The sound tubers were packed in net package (2kg in weight) and stored under room conditions at Post Harvest Lab. Horticulture Department of Faculty of Agriculture, Benha University. The average of normal room temperature during the two storage seasons of 2017 and 2018. Stored tubers were inspected at every month interval for determining weight loss, decay and chemical analysis. Obtained results showed that, It is evident clearly that planting potato by cutting tubers then fertilized with 100% of the recommended N dose at 120kg/fed as organic form(chicken manure) combined with the soil addition of EM at 10% three times gave the lowest weight loss and decay percentage and the highest dry matter, protein and starch content during storage period (4months) under room storage conditions. | ||||
