This study was conducted with the aim of making a new approach to plant fertilization based on nano-fertilizers and vermicompost and its positive effect on soil health. This work was carried out in the experimental research shade house of National Research Centre, Dokki, Giza, Egypt during (2020- 2021). For this purpose, healthy 5 years old fig seedlings sultani cultivar. The seedlings were planted in black polyethylene pots with 30 cm diameter fooled. with use 10 kg washed sand mixed very good with use three concentrations of Vermicompost 500 -1000 and 1500g/seedling ,with adding varied doses of Nano-NPK(20:20:20) fertilizers (200, and 400ppm) as foliar application. Nano-NPK fertilizers treatments were applied two times monthly during active season, also fig  seedlings were irrigated twice weekly .At the end of each growth season, leaves were collected to record some vegetative parameters (leaf fresh and dry weight and leaf area) then these samples of leaves were dried and digested to determine nutrient statues under tested treatments. Moreover, Estimation of microbial and enzymatic activities of vermicompost. Obtained results indicated that, substituting half recommended dose of spraying with Nano-fertilizers at (400 ppm) positively promote most of recorded vegetative growth parameters and without any deficiency symptoms on seedlings. Also, The microbial and enzyme activities of the soil are closely related to the organic matter content and influenced by all practices applied for soil including adding fertilizers, emphasize these impacts of organic matter as vermicompost and nano-fertilizers. Besides, all treatments (vermicompost + nano-fertilizers) resulted in increasing enzyme activity comparing with control treatment. Also, indicated that at the same level of nano-fertilizers, increasing vermicompost dosses lead to increase enzyme activity particularly in level 200ppm of fertilizers.

1-Methylcyclopropane (1-MCP) is an ethylene inhibitor tested for maintaining fruit quality and extending storability of Tommy Atkins mango fruits as an export variety. The fruits were harvested at maturity stage in July 2019 and 2020, immersed in (1-MCP) water solution at 750, 1500 and 2250 ppb for 5 minutes besides control fruits were soaked in tap water for the same period. Fruits were air dried then cold stored at 8°C and relative humidity (RH) 85-90% for 15,30,45and 60 days. After each storage period fruits were holding to ripe at 20°C for 7 days, At the end of storage period either 8°C and 20°C, fruit quality characteristics (weight loss, decay percentage, firmness, respiration rate ,TSS % and total acidity %) were evaluated. The results revealed that (1-MCP) at 1500 ppb and storage at 8°C for 45 days was the best treatment for maintaining fruit quality after cold storage and the following ripening period at 20°C.
