ctivity Dynamics (LPD) in Egypt, during the 2000 - 2019 period as well as identifying drivers and hotspots of land degradation aiming at realizing the promotion of the land’s sustainable development and degradation neutrality. The study is based on remotely sensed images (SPOT Vegetation NDVI) aggregated / composited to observation every 10 days at a spatial resolution of 30 m calculated by the Joint Research Centre. Results showed that trends of the net LPD for each of the degraded land cover categories were 0.4%, accounting for about 11415 sq. km (1.14% of Egypt’s land area). On the other hand, the increasing trend of LP has been attained for both of the shrubs and grassland together with croplands, accounting for around 2077 and 10921 sq. km respectively representing together about 1.3 % of the country’s land area. During the study period, mismanagement of soils and water resources has been the chief reasons for the changes in LP. Worthy mentioning, that RS, NDVI and GIS are considered essential tools for LPD monitoring and assessment.

A field experiment was conducted during the two successive winter season 2018-2019 and 2019-2020 at Sahle El-Houssinia Agric. Res. Station, El-Sharkia Governorate to study the effect of foliar application of humic acid and yeast industrial waste (liquid and dried) on faba bean (Visia faba) yield, yield components and some soil properties of salt affected soil. The treatments were 8 gL, liquid yeast waste 6 cmL and dried yeast 10 gmL. Humic acid and yeast waste were sprayed during growth period four times every 10 days after 30 days from sowing by 600 L.ha- on soil and plants. Application of humic acid and yeast waste (liquid or dried) decreased soil pH, EC, ESP, increased infiltration rate, porosity, stable aggregate and decreased bulk density for two seasons. Also, application of humic acid and yeast waste were significantly effect on plant height, number of branch / plant, number of pods plant, weight of 100 seeds, biological yield and seed yield. Seeds N, P, K, Fe, Zn, Mn contents significantly increased compared to control due to application humic acid, liquid yeast and dried yeast.

Two field experiments were carried out as split-split plot design at Experimental Farm of Tag El-Ezz, Agricultural Research Station (30o59\ N latitude, 31o58\ E longitude´), Dakahlia Governorate, Egypt, during winter seasons of 2018-19 and 2019-20 to study the integration managements of N and S fertilizers as three nitrogen sources in main plots as (urea(Ur), ammonium nitrate(AN) and ammonium sulfate(AS)), two elemental sulfur(ES) treatments (without and with sulfur as a soil application) in sub plots as well as in addition to three amino acids(AA) treatments (control, L-methionine and L-cysteine) as foliar application in the sub-sub plots on growth, yield and its components of onion plants (Allium cepa L.) cv.Giza Red(GR) were studied. Available elements N,P,K and S in the experimental soil were determined before cultivation and after harvesting. The obtained results could be summarized as follow: AN fertilizer give the highest effective vegetative growth values, quality parameters, yield and its components compared to other nitrogen sources. Soil application of ES has a significant effect on all studied parameters, while L-methionine is more effective than L-cysteine. Interaction of AN and foliar application of methionine in integration with ES application achieve the highest values of vegetative growth criteria, quality parameters, yield and its components of the onion plants. Highest residual NPK concentration in the soil were recorded with the interaction of AS and without ES and AA application, while the highest values of residual S are obtained by the interaction of AS and methionine foliar application in presence of ES application.

The effect of different overhead heights, pressures and water stress to determine high uniformity and water relations of wheat as well as yield and yield components under overhead floppy sprinkler was addressed in this study. The experiments and measurements were designed and implemented at the experimental farm of ElSalhia, ElSharkia Governorate, Egypt during the winter season of 2018-2019 to study. The uniformity coefficient (UC) and uniformity distribution (UD) were calculated under five levels of pressure (100, 150, 200, 250 and 300 kPa), four overhead heights (1, 2, 3 and 4 m) and water stress (20, 40, 60, 80 and 100% of evapotranspiration (ETc)). The results indicated that the highest values of UC and UD 72.14 and 58.13%, respectively were succeeded with pressure of 200 kPa and 3 m height for overhead floppy. Also, the results showed that water stress from 20 to 100% ETc with optimum operating conditions were carried out to get up high wheat production. The total yield and yield components were increased with decreased water stress. Also, the total yield was increased with increasing ETc from 20 to 100%. The grain and straw yield values were increased by 68.98, 66.55, 55.66 and 35.35% & 69.70, 64.29, 50.00 and 44.44% compared with 20% for overhead floppy. The maximum yield production and components were achieved with 100% ETc, while water use efficiency (WUE) with 20% ETc was maximum value. Finally, under the current experimental conditions, it could be concluded that the application of irrigation water 100% ETc under pressure of 200 kPa and 3 m overhead height with high UC and UD for overhead floppy sprinkler was the best system for obtaining high wheat yield production. On the other hand, using the application of irrigation water 80% ETc could be suggested to get high yield production and save water which will lead to deal with future water scarcity.

In Egypt, the improvement of degraded soils is considered as an important issue in the agricultural security program. Large amounts of sugar industrial wastes such as sugar lime mud is producing annually causing some issues to the environment if not exploited. So, a pot trial was carried out to evaluate the influence of some soil amendments on enhancing some chemical and physical characteristics of some degraded soils of Egypt. Three soil types (saline, sandy and sodic soils) were used and treated with three soil amendments i.e. compost, agricultural gypsum and sugar beet mud which were applied to the three studied soils (two weeks before sowing) at three rates (0.5, 1 and 1.5%, equivalent to 2.5, 5 and 7.5 g pot-1, respectively) and moisted after addition to the saturation limit. Soils were cultivated with barley. At the end of the trail, undisturbed soil samples were taken from each treatment .The findings show that barley seeds did not succeed in germination under sodic soil conditions, while seeds succeed in germination under saline and sandy soils. Generally, soil addition of all studied amendments at all rates pronouncedly improved all studied chemical and physical characteristics of saline, sandy and sodic soils compared to control treatment (without soil addition), but the improvement increased with the increase of adding rate of all soil amendments under study, where the best values were recorded due to the soil addition rate of 1.5% followed by 1% and 0.5%, respectively for all soil characteristics. Also, the results confirm that sugar beet mud as a new soil amendment in Egypt is beneficial for improving degraded soils due to its high content from organic matter and calcium.

Throughout two successive years (2018-2019 and 2019-2020), field experiments in split-split plot design with three replicates by combining three phosphorus levels (0, 50 and 100% from recommended doses) and two addition ways of zinc (soil and foliar) half of treatments inoculated with PSB and the other half without inoculation. P fertilization individually comparing with the control (non-fertilized) on faba bean increased significantly all of vegetative growth parameters (plant height, fresh and dry weight), chlorophyll content. P and Zn content increased in shoots and decreased in roots as well as yield and its components (seed index, weight of pods, total yield, total carbohydrates and protein) were increased and recorded the highest values at 100% RD. The results in this study showed that, foliar application with Zn-EDTA was the most suitable form significantly affected in all mentioned parameters. Also, in the same experiment found an increase in all studied parameters in inoculated plants with PSB.

In the most countries, losses of fruits and vegetables during post-harvest process are of a wonderful concern to fruit-traders, farmers and consumers. The aim of this work is to study the effect of cucumber hydrocooling treatment ‘HY’ before putting cold room on its qualities and properties. ‘HY’ system conformed by putting cucumbers in cold water at “4 °C” with ratio of three units of water mass to one unit mass of ice and to one unit of cucumber mass (3:1:1). The cucumber “HY” treatment and non-hydrocooled (control, CR) were stored in cooling room under three different temperatures of 5.0; 9.0 and 13.0 °C, relative humidity of “ 90±5 %” and five times of storage “3.0; 6.0; 9.0; 12 and 15 days”. The changes in diameter, length and volume, firmness, mass, color parameters and total soluble solids (TSS) were determined as the most important factors affecting the cucumber quality during cooling. Results showed that, there are high significant differences between all treatments and the averages of all previous determinations such as changing in each of cucumber diameter, length, volume, firmness, mass loss, “TSS” and color parameters (L, a, b and ΔE). On the other hand, un-significant differences are found between the interactions of all treatments and the averages of mass loss and some color parameters of "a" (inner and outer) and b (outer). The “HY” treatment confirms a greatest higher on firmness and TSS. But it is recorded a slower loss of fresh mass, diameter, length and volume at comparing with “CR” method. Seven/eight cooling time “TAT7/8”, percentage of mass loss rate, lowest firmness and total color difference “ΔE” inner/outer” recorded at “HY” methods of” 7.5 m” ;”0.11% h-1 “; “10.44N” and “4.56/5.74’ respectively, compared with “CR” method of “126 m”;“0.19% h-1”; “7.04N” and “5.04/ 5.44” at 13°C after 15 days of cold storage. But the highest mean value of “TSS” is found at “HY” system and recorded “3.89 ± 0.0013” at 5°C after 3 days of cold storage.
