Two field experiments were carried out during growing seasons 2011 and 2012, it executed in research farm of National Research Center Nubaryia region, Egypt to study the effect irrigation systems, fertigation rates using wastewater fish farms potato crop under sandy soil conditions. Study factors systems (sprinkler system ―SIS‖ drip ―DIS), water quality (irrigation ―IW‖ drainage ―DWFF‖) (FR1= 20%, FR2= 40%, FR3= 60%, FR4 = 80% FR5= 100% from recommended dose NPK).The following parameters...

Abstract Purpose The current study aimed to investigate the efficacy of zinc oxide nanoparticles (ZnO NPs) synthesized by Melia azedarach aqueous extract control Hyalomma dromedarii tick, and evaluate their toxic effects on Swiss albino mice. Methods ZnO NPs were using M. extract. UV–visible spectroscopy, Fourier transform infrared scanning electron microscopy, energy-dispersive spectroscopy used characterize NPs. Egg, nymph, larva, adult immersion tests for bioassay tick stages with NP. A...

This study aimed to demonstrates a positive correlation between silica metal tolerance ability of drinking water fungi and its potential for the synthesis oxide (SiO2) nanoparticles (NPs). Metal NPs can be synthesized biologically by different methods including; microorganisms, plant extracts and\ or biomass. These in some time are better alternatives chemical physical through an environmentally route. In present work, twenty fungal strains were isolated from eight potable samples tested...

Two field experiments were carried out during growing seasons 2011 and 2012. It was executed in research farm of National Research Center Nubaryia region, Egypt to study the effect irrigation systems, fertigation rates by using wastewater fish farms “WWFF” potato. Study factors systems (sprinkler system “SIS” trickle “TIS”), water quality (traditional “TIW” WWFF) “FR” (20%, 40%, 60%, 80% 100% NPK). The following parameters studied evaluate factors: 1) Calculating total amount WWFF per...

This study was carried out to investigate the effect of different levels dietary selenium enrichedmicro-algae supplementationon growth performance, carcass characteristics, blood biochemical constituents, and anti-oxidative status rabbitsunder Egyptian summer conditions. Total 90 male growing New Zealand White rabbits, six weeks old with an average initial body weight 757.5 g were used in this study. Rabbits randomly allocated experimental groups, 15 rabbits each group. The first a control...

Different formulations of pepper mint oil, i.e. bulk, nano-emulsion and nano-encapsulation were evaluated against 2nd 4th instar larvae the cotton leafworm Spodoptera littoralis (Boisd.). Their effects on enzymatic activities bionomics also investigated. Transmission Electron Microscopy (TEM) showed that mean particle size prepared ranged between 20-90nm. The encapsulation efficiency loaded capacity percentages exhibited distilled H2O was more suitable than ethanol in preparation particles....

Objective: The rates of some Potential Toxic Elements (PTEs) release from three contaminated soil ecosystems with high zinc equivalent values were kinetically compared to select the best remediative management technique(s).Methodology: sampled irrigated either industrial effluent for more than 80 years (Kafr El-Sheikh site), sewage 50 (Konbera site) or drainage water mixed river Nile 35 (Sinai site).A kinetic study PTEs applied using two empirical models i.e., Modified Freundlich Elovich...
