A novel nano bio-fertilizer encapsulation method was developed to crosslink chitosan and alginate with humic acid. These nanocapsules, referred as (Ch./Alg.HA.NPK) or (Ch./Alg.HA.NPK.PGPRs), were loaded nanoscale essential agro-nutrients (NPK) beneficial microorganisms Pseudomonas Fluorescence abbreviated (P.Fluorescence). Structural morphological analyses conducted using FourierTransform Infrared, Thermogravimetric Analysis, Scanning Electron Microscopy, Malvern Zeta NanoSizer, potential....

Abstract Citrus hosts various phytopathogens that have impacted productivity, including viroids. Missing data on the status of viroids in citrus Palestine were not reported. This study was aimed to detect any exocortis viroid (CEVd), viroid-III (CVd-III), and viroid-IV (CVd-IV) Palestinian National Agricultural Research Center (NARC) germplasm collection Field inspections found symptoms such as leaf epinasty; vein discoloration, bark cracking varieties. RT-PCR revealed a significant...

Olive hosts 13 viruses belonging in seven different genera. Additional non‐mechanically transmissible probably infect olive nature, as suggested by the widespread occurrence of double‐stranded RNAs (dsRNAs) trees from which no can be recovered manual inoculation. Because sanitary selection appears to only measure for restraining virus dissemination through propagating material, detection methods are needed more sensitive and reliable than those currently available (biological serological)....

The high level of copper (Cu) accumulation in the soil, risk surface water contamination, and potential public health problems due to Cu entering food chain have raised concerns on use compounds agriculture, including olive growing. As a consequence, there is worldwide regulatory pressure agricultural systems limit compounds. Hence, field trial was carried out evaluate effectiveness low containing chemicals control leaf spot (OLS) disease caused by Venturia oleaginea. conducted 2021 an (cv....

Olive (Olea europaea) is host of 13 different viruses but, it possible that other viruses, which are either non mechanically transmissible or occur in low concentration plant tissues, present nature. This likelihood supported by the widespread occurrence double-stranded RNAs (dsRNAs) plants negative to biological tests. As very little information available on geographical distribution olive-infecting, investigations were conducted for gathering prevalence and olive Mediterranean basin based...

Different pollutants from industries leach every day to soil and ground waters without treatment. The product N,N-bis (3,5-Dimethylpyrazol-1-yl methyl)-3-aminopropyl Polysiloxane (Si-C 3 H 6 NPz 2 ) was successfully prepared. FTIR results confirmed that the dimethylpyrazole units have been immobilized onto surface of modified silica gel. adsorption experiments were conducted for a wide range solution pH, adsorbent dosage, temperature, initial concentration contact time. It observed...

Several thymes species were grown in Palestine and have socio-economical values. Traditionally, morphological features are used for their taxonomy discrimination. However, these methods fail to provide an accurate discrimination authentication, suggesting the use of other method inevitable. In this study, RAPD was genotypes identification characterization five most Palestinian thymes: Thymus syriacus, fruticosus, incanus, majorana, capitatus. Eight out ten decamer primers tested ability...

This research was aimed to assess the photosynthetic activities of barley (Hordeum valgare L.), clover (Trifolium repens and pearl millet (Pennisetum glaucum (L.) R. Br.) under different saline conditions with two strains Pseudomonas putida (UW3 UW4) treatments. An exceptional observation revealed on biomass ratio (288.8%) that irrigated brackish water (10,000 mg/L) presence P. UW4 strain. In general, UW3 strain significantly increased crops (249.4%, 202.1%, 212.5%) for barley, millet,...
