| Abstract | ||||
| This study was processed at the experimental orchards, Agriculture of Faculty, Assiut University, Egypt, to survey impact of nitrogen fertilizers at different sources on Manfalouty pomegranate trees growth, yield and fruit quality in 2020 and 2021seasons. The research design was randomized complete block of eight treatments with three replications. The results findings as follow Amending the advised of nitrogen dosage as twice (mineral-N plus organic or bio-form) or three sources of nitrogen fertilization were used: mineral-N, organic-N and bio-N form (mineral plus organic and bio-form) materially raised the shoot length, leaf surface, chlorophyll, leaf content of N, P and K comparing to mineral-N source only (control). All amending treatments materially raised the yield/tree, commercial fruit % and materially reduced the percentage of fruit cracking and sunburn comparable to use control. Amending with any triple form (organic + bio + mineral) materically amended the fruit traits due to raising the fruit weight, arils percentage, soluble solid contents, sugar and contents of anthocyanin and vitamin C and reducing the acidity and tannins contents comparing to use control treatment. It is obvious from the obtained data that the interest of organic and bio manures for pomegranates forms, where this is desired to amend the trees growth and nutritional status and production quality and then the package yield. Moreover, these amending reduce the production cost and ecological contamination. | ||||
