The added rates organic fertilizer 10 ton / fed. chicken manure, 10 ton / fed. cow manure ,160:175 (N) unit per fed 75 (P) unit per fed 75 (K) unit per fed. The results indicated that potato plants fertilized with half recommended dose of NPK + Chicken manure treatments gave significant effects on total yield of potato tubers (ton / fed.), weight of non-marketable tubers (kg / fed.), total yield of potato tubers (g / plant), number of potato tubers per plant ,crud protein content (%), total carbohydrates content (%), and total sugars content (%) UR - http://nile.enal.sci.eg/EALE/2015/FJARD/2915/2/52.pdf ER -
