Effect of Integration Vermicompost and Nano-Fertilizer on Fig Seedlings Growth and Soil Health

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