| Abstract | ||||
| This investigation was carried out in a private the Orchard, located at El-Badary distinct, Assiut Governorate, Egypt, to study the effect of organic and bio-form fertilizers on vegetative growth, nutrient status and fruiting of Manfalouty pomegranate trees during 2019 and 2020 seasons. The experiment was arranged in a complete randomized block design with five replications, using a tree as an experimental unit and it consisted of five treatments. The obtained results could be summarized as follow: Using the recommended dose of nitrogen (RND) via thrice form (mineral plus organic and bio-form) at any percentage significancy increased the shoot length compared to use RND via mineral-N fertilizer (check treatment). All fertilization treatments significantly increased leaf area, chlorophyll content and the percentage of N, P and K in leaves compared to check treatment. No significant differences on these vegetative parameters due any combination of fertilization. Also, all fertilization treatments significantly increased the yield/tree and significantly decreased the fruit splitting and sunburn percentage compared to use mineral-N source only. Fertilization with any twice form (organic plus mineral)or thrice form (organic + bio + mineral) significantly improved the fruit quality in terms of increasing the fruit weight, arils percentage and total soluble solids as well as sugar, anthocyanin and vitamin C contents and decreasing the total acidity compared to using the check treatment. | ||||
