The current work aimed to elucidate the effect of N mineral fertilization rates in combination with N bio-fertilizer source and its rate on barley yield <em>(</em><em>Hordeum vulgare L.)</em> var. Giza 2000 and its components in sandy soil. Afield experiment was conducted at Kantra Shark, north Sinai Governorate during 2017/2018 winter season using randomized complete block design with split split plot arrangements replicated three times. The main plots assigned to four mineral - N rates (0.0, 50, 75 and 100 kg N fed<sup>-1</sup>) as ammonium sulphate (205g N kg<sup>-1</sup>). The sub plots occupied by two commercial bio-fertilizer sources, Cyrialine and Microbine. The sub-sub plots dedicated to three bio-fertilizer rates (0.0,400,600 and 800 g fed<sup>-1</sup>). The results appeared that barley grain, straw and biological yields, harvest index(HI), grains protein content (%), N, P , K-uptake (kg fed<sup>-1</sup>) by grains or straw , total uptake (grains + straw) , agronomical and recovery (P and K) use efficiencies increased significantly with increasing N-fertilizer rate up to 100 kg fed-<sup>1</sup>.Agronomical, recovery nitrogen use efficiencies and physiological (N,P and K ) use efficiencies decreased significantly with increasing N-fertilizer rate. Cyrialine was superior to Microbine in its beneficial effect on most abovementioned traits. All studdedvegetative characters as well as chemical composition, nutrient uptake and nutrient use efficiency increased significantly with increasing bio-fertilizer rate. Generally, although the crop responsed to mineral N rates up to 100kg N fed<sup>-1</sup> under the studied soil (sandy), the combination application with bio-fertilizers was the best for all studied parameters and can save approximately 25 % of mineral N fertilizer at least as well as help in reducing mineral fertilizer pollution in growth media.

The soils of both wadies Qift and Zeidun are considered one of the promising parts of Eastern Desert, due to a wide area of arable land and the high potential of ground water. Additionally, the area is considered a good model for representing many of the landscape features, in the Eastern Desert. So this study aims to identify the different physiographic units including soil developed in this area by interpretation landsat ETM 8 image, as to determine soil suitability class that have closely relationships with physiographic characteristics. This technique plays an important role for utilizing these scanned promising areas. The area under consideration lies between latitudes (26<sup>o </sup>00ˉ) and (25<sup>o </sup>50ˉ) North and longitude (32<sup>o </sup>45ˉ) and (33<sup>o </sup>05ˉ) East and covered by Landsat TM8 image bands 2,4 and 7. The data obtained show that the studied area were identified physiographically, as:(1) Rubble Terraces (stony pediment soils), old alluvial terraces (high & low),young alluvial plain terraces (high & low) , fan and outwash plane, wadies (wadi bottom and wadi plain) and Miscellaneous land types (Rock land). According to the morphological features and analytical data, the soils developed on the main physiographic units are classified till the family level into: A: <em>Aridisols</em> , soil families are : 1-<em>Typic Calcigypsids</em>, sandy skeletal, mixed , hyper thermic, (old and young alluvial terraces(high & low) and wadi bottom soils.2- <em>Typic Calcigypsids,</em> loamy skeletal, mixed ,hyper thermic at the soils of old alluvial terraces (high) and wadi bottom soils. 3- <em>Lithic Haplocalcids,</em> loamy skeletal, mixed , hyper thermic, (Rubble terraces stony pediment). 4- <em>Typic Haplocalcids,</em> sandy skeletal, mixed, hyper thermic at old and young alluvial terraces (low) and wadi bottom soils. 5- <em>Typic Haplocalcids,</em> loamy skeletal (young high terraces) and wadi bottom. B: <em>Entisols</em> included: 1- <em>Typic </em><em>Torripsamments</em><em>,</em> sandy skeletal, mixed, hyper thermic young alluvial terraces (low), fan and outwash plain. 2- <em>Typic Torriorthents</em>, sandy, mixed, hyper thermic (wadi plain soils). The soil evaluation results of the studied soils revealed that the soils of wadi bottom and wadi plain soils currently marginally suitable lands (S<sub>3</sub>) and moderately suitable (S<sub>2</sub>). Fan and out wash plain and some soil of low young alluvial terraces currently are marginally suitable lands (S3). Whereas, Rubble terraces stony pediment soils, and some soil of old alluvial terraces, and high young alluvial terraces are currently not suitable (N1). In addition, the limiting factors for soil productivity are topography, soil texture effective, soil depth, CaCO<sub>3</sub> content, salinity and alkalinity. Potential suitability was identified after required land improvements and reveal that all the studied soils are placed between marginally and moderate suitable (S<sub>3 </sub>& S<sub>2</sub>). The limiting factors for soil productively are soil texture and soil depth.

The purpose of this research was to study the impact of N levels applied with proline as well as plant distance on the vegetative growth, chemical content, yield, yield components, and quality attributes of maize under different irrigation intervals. The research was undertaken at an experimental field of Agricultural Faculty, El-Mansoura University during 2018-2019. The results showed that application of 150% nitrogen fertilization from recommended dose in presence of 50 mg/l proline significantly increased growth parameters (plant length, fresh and dry weight of flag, leaves area), chlorophyll content, N, P, K and proline content of maize leaves as well as yield attributed (ear length, 1000-graine weight, grain yield and straw yield) and quality of grains (crude proline, fiber, total carbohydrates and oil%). All parameters under investigation recorded high significant values with plant spacing 15 cm. As for irrigation intervals the results revealed that 11 days' intervals were the most suitable for previous maize parameters. So, it could be recommended touse150 N-fertilization in presence of proline + 15 cm plant spacing and 11 days' irrigation intervals.

This research aims to study effects of some factors on design of rice straw-bales chopper to solve the operation problems such as un-continuous rice-straw feeding rate to a cutting unit, the feeding-platform height and the rice-straw cutting size. The experiments were conducted to determine the optimum operation factors to achieve the straw lengths desired for the animal feeding and compost. The studied factors were type of knives (free, fixed-curved and free fixed-curved), chopping-drum speeds of 1450, 1750, 2050 and 2350 rpm (34.16, 41.23, 48.3 and 55.37 m/s) and feeding-mechanism speeds of 0.26, 0.31, 0.35 and 0.42 m/s. The Experiments recorded that increasing chopping-drum speed from 1450 to 2350 rpm, decreased the mean straw cutting-length from 9.12 to 4.92, from 7.95 to 3.65 and from 7.31 to 3.31 cm using free, fixed-curved and free fixed-curved knives type respectively at all tested feeding-mechanism speeds. The maximum chopper productivity of 1.2 Mg/h was recorded by using chopping-drum speed of 2350 rpm and feeding-mechanism speed of 0.42 m/s, meanwhile, the minimum chopper productivity of 0.92 Mg/h was recorded by chopping-drum speed of 1450 rpm and feeding-mechanism speed of 0.26 m/s at all cutting-knives type. The results revealed that increasing chopping-drum speed from 1450 to 2350 rpm, increased the chopper power-requirement from 3.51 to 7.12, from 4.15 to 7.75, and from 4.78 to 8.23 kW, while, increasing chopping-drum speed from 1450 to 2350 rpm, the chopper specific-energy increased from 3.81 to 5.93, from 4.5 to 6.46 and from 5.19 to 6.86 kW.h/Mg by using free, fixed-curved and fixed-curved knives type respectively at all tested feeding-mechanism speeds.

This study was conducted during 2017 and 2018 seasons on 5-year old Superior grapevines in a farm located at Minia - Abokerkas western desert road, Egypt. The aim of this investigation was to study the effect of nitrogen sources: (Calcium nitrate15.5% N as a fast fertilizer and urea form 40% N as a slow fertilizer), with two nitrogen rates (40 and 70 N units) on the growth and yield of Superior grapevines. The results showed that, the leaf N content was significantly affected by nitrogen applications. The highest value of leaf N content was 2.68 - 8.83% with 70 units calcium nitrate (F-70) treatment after both seasons. Leaf P content ranged from 0.11 to 0.41% in both seasons. Leaf K content was un-significantly affected by either the tested N sources or their rates, comparing to control (C) treatment. Leaf K content ranged from 0.79 to 1.41 and 0.69 to 2.00 % in 2017 and 2018 seasons, respectively. Leaf area was significantly affected by fertilizer types or rates. The leaf area (average value) could be arranged in descending order F-70 > F-40 > S-40 > S-70 in both seasons, the highest yield was recorded under urea form 40 units (S-40) and (S-70) treatments. The highest values of total soluble solids, TSS/acid ratio, total sugars, reducing sugars and the lowest values of total acidity were obtained with (S-70) treatment in the second season. Soil nitrogen content, available potassium and available phosphorus was significantly increased by the tested sources rates of fertilizers after the second season compared to the first season. The utilizing of N fertilizers either as urea form or calcium nitrate elevated the amount of N, P and K in the soil compared to control.

The aim of the study was to evaluate the land capability and suitability for some crops through determining soil physical, chemical properties and fertility in some soils of East Nile Delta in Dakahlia Governorate by using ASLE program and GIS techniques. ASLE program was used for calculating land capability and suitability for some field crops, vegetables crops and fruit trees with a total of 15 crops. For this purpose, 15 soil samples were randomly distributed within the studied area at a depth of (0-30, 30-60 and 60-90cm), which were subjected to physical and chemical analyses. Results indicate that the studied area was classified into two soil classes (i) excellent-C1 and (ii) good-C2. While, the land capability was fit into two classes: I- C2 (good) and II- C3 (fair). Concerning land suitability, studied crops can be grown in these soils. These crops were classified according to land suitability of studied area into three classes: (i) S=very suitable (wheat, rice, maize, sugar beet, alfalfa, barley, faba bean, pea, cotton, potato, grape, and citrus), (ii) S3= moderately suitable (tomato) and S4= marginally suitable (onion and pepper). The suitable field crops could be arranged by preference as: sugar beet < wheat < rice < barley < maize < faba bean < cotton < alfalfa < onion. While vegetables crops arranged by preference as: pea < potato < tomato < pepper < onion. Meanwhile, grape was the optimum fruit trees followed by citrus.
