The current investigation was executed at in a private the Orchard, located at El-Badary district, 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 and it consisted of five treatments.The results can be summarized as follow:Using the recommended dose of nitrogen (RND) via thrice form (mineral plus organic and bio-form) significantly increased the shoot length compared to use RND via mineral-N fertilizer (check treatment). All fertilization treatments significantly increased leaf area, chlorophyll and contents of N, P and K in leaves compared to check treatment. The 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 properties by 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.It is clear from the current results the importance of fertilization through organic and bio-form for pomegranates productivity, via improve the fruit quality which reflects on induce the increase packable yield. In addition, such fertilization treatments reduce the cost of production and environmental pollution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
