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.

Calculation of threshold current density and efficiency for multiple quantum wire of 〖Hg〗_(0.5) 〖Cd〗_(0.5) Te/〖Hg〗_(0.8) 〖Cd〗_(0.2) Te/CdTe laser

“…quantum wires (QWR) and quantum dots (QDs), as the natural evolution path toward the ultimate semiconductor laser device [5]. In low dimensional QW structures, such as quantum wire (Q-wire) and quantum box (Q-box or Q-dot) structures, carriers are more strongly confined than in quantum film (Q-film) due to the further modification of band structures and density of states (DOSs) distributions [6]. Therefore, the threshold current, differential quantum efficiency, and linewidth of Q-wire and Q-box lasers have been expected to be superior to those of Q-film lasers [6].…”

Characterization of nickel sulfide and zinc sulfide nanostructures

“…Several methods to synthesize the metal sulfide have been reported in the literature such as the chemical vapor deposition method [15], the hydrothermal method [16], the chemical bath deposition method [17], and the chemical co-precipitation method [18].The solvothermal method has also been used to fabricate hierarchical like the structure of β-NiS which approaches the specific discharging capacitance of 857.67 -513 F/g at current density 2 -5 A/g [17]. Nanoflake arrays based NiS were synthesized through the chemical bath deposition process with specific capacitance of 718 F/g at current density 2A/g [19].…”

“…NiS thin films synthesized via the chemical bath deposition procedure used to identify the chargedischarge behavior and exhibited maximum energy and power density of 11.7 Wh/kg and 4.3 kW/kg, respectively at a current density of 1 mA/cm2 [21]. Nanocomposite of NiS/ZnS were synthesized on nickel foam through the CVD process that reached specific capacitance 1533 F/g at 7.5 Ag-1 [15]. In the present study, star-like NiS and spherical ZnS nanocomposites have been synthesized using the hydrothermal method and elaborately characterized.…”

ZnO nanostructure fabricated by electrochemical deposition

“…Up till now, many various techniques have been explored to create superhydrophobic ZnO nanostructures. For instance, pulsed laser deposition [8], plasma treatment [9], sol-gel technique [10,11], chemical vapor deposition [12,13], electrochemical deposition [14][15][16][17][18], hydrothermal method [19], and templated electrosynthesis [20]. Among these methods, cathodic electrodeposition offers an efficient way in generating ZnO nanostructures due to low cost, large-scale deposition, environmental friendly, simplicity and low temperature growth.…”
