| Abstract | ||||
| Two field experiments were conducted during 2013 and 2014 summer seasons at a special Farm in El-Basunia Village, Fayoum District, Al-Fayoum Governorate, Egypt, to study the effect of Eight fertilization treatments i.e. Chicken manure, Cow manure, Chemical fertilizer, bio-fertilizer, 1/2 NPK + Chicken manure, 1/2 NPK + Cow manure, 1/2 NPK + bio-fertilizer and control (without fertilization ) , on yield and quality of four potato cultivars i.e. Spunta , Nicola , Hermes and Lady Rosetta . 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 (%) . The results indicated that the potato cultivars varied significantly where, Spunta exceeded other cultivars in all characters studied. The type spunta and the following type Nicola gave the highest crop < br />for fed in ton and for plants in (kg ) in each of the two seasons , type spunta the best in protin rate and the type Hermes the best in carbohydrate total in tubers , the type Nicola the best in sugar the character of crop was effected and its continents and so the quality , and the chemical for potatoes tubers in the fourth characters for potatoes significant with the treatment fertilizers the highest value for all characters under studying and so that with fertilization with half recommended mineral fertilizer chicken manure fertilizer in all both to season but the treatment of comparison without fertilization led to short significant for all this characters in both seasons | ||||
