Assessing efficacy of jojoba crushed seed and oil cake on growth vigor, nutritional status of Superior grapevine cuttings and controlling the root-knot nematode CIGR Journal
Hafez, Omaima M..
The increasing demand for environmental protection and sustainable food production requires increasing towards the use of natural and non-toxic materials for agriculture. Thus, the target of the current research was assessing the efficacy of jojoba crushed seed, oil cake (seed after compressing) and bio-nematicide (Nema-Foo®) on growth and nutritional status of Superior grapevine cuttings as well as controlling Meloidogyne incognita in the Pomology greenhouse at NRC, Dokki, Giza, under Egyptian conditions during two successive seasons (2015-2016). Eleven treatments were done on Superior grapevine cuttings (one year old) as jojoba crushed seed and jojoba oil cake (3 and 6 g, for each) with or without infection, Nema-Foo® (5 %) with infection were added, in...

Enhancement yield and fruit quality of Washington Navel orange by application of spraying potassium microencapsulated biodegradable polylactic acid CIGR Journal
Hafez, Omaima M..
This research seeks to improve the fertilizer use efficiency, particularly potassium nutrient, and to minimize any possible dose losses. The improvement was applied by the use of foliar sprays by encapsulated potassium element into biodegradable polymer. The potassium polylactic acid microspheres (K-PLA) were characterized by Gel Permeation Chromatography (GPC) and Scanning Electron Microscope (SEM).  Piratical size and zeta potential measurements were investigated. Thermal behavior (TGA and DTA) was studied. In capsulation percentage of potassium into PLA microspheres was 4.5 W %. Cumulative release was estimated by inductive coupled plasma-atomic emission spectrometry (ICP-AES), the maximum cumulative release was 3.74 % after 12 hours. Washington Navel...
