Depending on the geochemical forms, heavy metal (HM) accumulation is one of most serious environmental problems in world and poses negative impacts soil, plants, animals, humans. Although use biochar to remediate contaminated soils well known, huge quantities waste used its recycling technique sustain soil addition conditions are determinant factors for characteristics uses. A pot experiment was conducted a completely randomized block design evaluate forms their availability under...
HE PRESENT investigation was conducted to study the genetic variance components, heritability, heterosis and combining ability in relation identifying desirable parents hybrids for hybrid rice breeding program.Three cytoplasmic male sterile (CMS) lines five restorers (testers) were crossed line × tester scheme 2014 growing season.The resulted 15 F 1 along with their eight parents, three maintainers one standard check variety (Giza 178) evaluated a randomized complete block design (RCBD)...
A field trial was carried out at The Experimental Farm of Al-Sheikh Allam Al-Monshaah, Sohag governorate, Egypt which is located 26° 52- 41= N latitude and 31° 75- 96= E longitude during two successive growth seasons 2017/18 2018/19 to investigate some natural soil amendments (poultry manure, PM; farmyard, FYM; compost, CO ; mud rock, MR) with application levels (20 40 ton/ fed) (fed= feddan= 0.420 hectares = 1.037 acres) assess their effects on hydro-physical properties find the suitable...
The experimental field was conducted at the farm, Fac. of Ag., Al-Azhar U., Assuit, during two growing summer seasons 2018 and 2019.A experiment designed as randomized complete block with split split-plot arrangement treatment three replications.The current study aims to evaluate different irrigation methods (conventional alternative furrows) nitrogen fertilizer Sources (urea fast ureaform slow one) for maximizing production some cotton varieties (G80 G90) well define most favorable manner...
The present study revised taxonomy and occurrence of the ghost crabs (genus Ocypode) fiddler Uca), belonging to family Ocypodidae collected from different localities Egyptian Red Sea Mediterranean coasts. A total six species were collected, comprised three crabs, represented by Ocypode cordimanus, O. cursor, saratan including Uca albimana, U. inversa, tetragonon. With exception cursor which was only recorded Sea, all other five Sea. All construct permanent burrows in supralittoral sandy...
The research problem is concentrated in that despite the comparative advantage for production of fresh peach crop, Egypt occupies position No. 19 among biggest exporters crop world with a relative importance amounted to about 0.34% total exports peaches 2014. This addition decline amount from represent 1.6% fruit 2013. aims study current situation and Exports Egyptian competitiveness indicators inside most important export markets. These results showed area 81 000 feddans as an average...
Two field experiments were conducted in a new soil extention El Qantra-West, Ismailia Governorate, Egypt during 2017 and 2018 summer seasons.The study aimed to evaluate the effect of six exogenous application levels ascorbic acid (AsA) micronutrients mixture on yellow corn hybrid 352 (three way cross) under three amounts irrigation water (3750, 3000 2250 m 3 /fad., estimated crop evapotranspiration) using surface system.A randomized complete block split plot design with replicates was used...
A total of 161 specimens C. sapidus were collected during the fishing season from November 2016 to July 2017, 100 males (62.1%) and 61 females (37.9%). The number obtained has seasonally fluctuated. highest individuals was 67 (41.6%) spring, compared with minimum 28 (17.4%) in summer. present results showed that 87.3% population fell within 75 124.9 mm CW represented by two modes comprising sub adults adults. There seasonal changes size frequency distribution pooled samples this species....

The field experiment was carried out at a private farm, Eneiybes, Juhayna, Sohag governorate, Egypt which is located 26 73 -67 = N latitude and 31 47 -56 E longitude during two consecutive growing winter seasons of 2019/20 2020/21 to assess the effect seed priming on wheat yield water productivity under drought stress.The laid in split plots design with three replicates.The main were assigned stress (90, 75, 60% capacity, FC).The allocated treatments (No, Hydro CaCl2).The obtained results...
A field experiment was conducted during the winter season of 2017/18 and 2018/19 at experimental farm Arab El-Awammer Research Station, Agriculture Center, Assiut, Egypt (27° 11/ N latitude, longitude 31° 06/ E 71m altitude ASL) to evaluate effect different irrigation regimes (80, 100 120% reference evapotranspiration (ETo) various intercropping patterns (wheat faba bean intercropped with sugar beet) under drip system on beet yield its traits, crop water productivity land equivalent ratio....
Two field experiments were carried out during 2014/2015 and 2015/2016 seasons at Agric.Exp.Res.Sta. Giza, Fac.Agric., Cairo Univ. to study the influence of three nitrogen fertilizer levels (75, 100 125 kg N/fad.), seeding rates (200, 300 400 grains/m 2 ), on growth wheat cultivars .Nitrogen had significant effect heading plant height in first season only flag leaf area both seasons.Absolute rate (AGR) was significantly affected by N 80 days from sowing.Leaf index (LAI) second only.Net...
A total of 693 specimens the freshwater crayfish, Procambarus clarkii were collected from four sites chosen along River Nile, at Helwan (Site #1), El Warraq (site #2), Rahawy #3) and Rayah Mounofy (Site#4) during period summer 2014 to following spring 2015.Most individuals characterized by hardrigid outer exoskeleton, with dark-red, or deep brownish color carapace.But some had old green grey carapace scars epibiotes.The showed spatial temporal variations, recorded 242 (34.92% all) Mounofy,...
An experimental field was carried out during the growing season of 2019/20 and 2020/21 at The Experimental Farm, Fac. Agriculture, Assiut, Egypt (27 12-16.67=N latitude 31 09-36.86=E longitude) in order to evaluate change soil moisture retention wheat plant response different irrigation practices as well their performances water productivity.The tested (border, furrow, alternative gated pipe surface drip) were arranged factorial a completely randomized design with three replicates.The...
Recently, intensive farming systems entailing abundant use of chemical fertilizers have deteriorated agricultural soils and contributed to environment pollution which necessitates testing organic amendments.The objectives the present multi-year study were investigate impact different soil amendments i.e. humic acid (HA) molasses (Ms) applied at 0.25 0.50% (v/w) on properties find out optimum application level for maximizing growth yield wheat.The results showed that bulk density (BD) total...
