Manufacturing of NPK nano fertilizer and its effect on growth and of cut flowers production in two types of Rosa spp

Abstract

NPK was made from the compound fertilizer ProSol (20: 20: 20) using an urgent mortar with 5 gm crushing for two hours until the conversion to nano size. nanoparticles size of the powder produced was measured by an X-ray diffraction meter XRD and the size of the produced was 54.13 nm. A field experiment was carried out using RCBD to study two factors, first type of fertilizer used with three levels of spraying with nutritious fertilizer ProSol at a concentration of 1.5 g. L-1 and spraying with NPK nano fertilizer at a concentration of 0.5 g. L-1 in addition to control treatment, second factor two types of rose damascene and Legend belongs to the Hybrid Tea Rose.  results showed that the treatment of spraying with nanoparticles was superior in all the studied characters, and it gave the highest number of flowering plants at 14.24. It also gave the highest concentration of nutrients in the leaves of 2.6 % nitrogen and 1.97 % for potassium. Legend superior to R. Damascena in number of flowers and carbohydrate content, while Damascena was superior in weight and flower diameter. The highest vase life recorded at 13.82 days for the treatment of interaction between spraying with nano fertilizer and Legend cultivar.
