EFFECT OF CULTIVATION MEDIA, IRRIGATION WATER SOURSES AND ORGANIC MANURE LEVELES ON YIELD OF CUCUMBER AND TOMATO UNDER PROTECTED GREENHOUSES AT NORTH DELTA
This investigation was conducted in plastic greenhouses at Sakha Agricultural Research Station to study the effect of different cultivation media, irrigation water sources andorganic manure levels onfresh yieldof cucumber and tomato and NPK contents of leaves and C/N ratio of rice bales .Split-split plot design with four replicates was used. The obtained results could be summarized as follows:
1. Fresh yield of cucumber grown on rice straw bales was increased significantly compared to clay soil, while tomato fresh yield grown on clay soil was higher than that grown on rice straw bales.
2. Fresh yield of either cucumber or tomato was decreased significantly with irrigation by well water or blended fresh with well water compared to fresh water.
3. Addition 20 ton of organic manure /fed. gave the highest fresh yield of cucumber or tomato, while zero level leads to achieve the lowest yield.
4. N and P contents of cucumber leaves were higher under cultivation on clay soil than rice straw bales, while the K took the opposite trend. Concerning the irrigation water sources, the contents of these elements were higher with fresh water than blended and well water, as well as, addition 20 ton organic manure /fed led to achieve the highest values of NPK content of cucumber and tomato leaves compared to other levels...
5. The C/N ratio of rice straw bales is decreased after cucumber and tomato harvesting comparing to that before the experiment. Using fresh water or blended water gave the lowest value of C/N ratio with cucumber and tomato .The increase of O.M application level up to 20 ton/fed leads to decrease C/N ratio with both growing crops in both seasons .

RELATIONSHIP BETWEEN LANDFORMS AND SOIL CHARACTERISTICS IN BAHARIYA OASIS, EGYPT
Bahariya Oasis is a natural depression located in the western desert of Egypt. The whole region is under hot arid condition. The images and GIS capabilities were used to generate soil maps. Six landforms were identified and soils availability of groundwater in the depression initiated cultivation of date palms and the associated industrial and economic activities. Due to abundant groundwater, the lands there gave indications of promising agricultural expansion. Study of the landforms and soils associated with them can give a general survey of soil characteristics. Landsat occupying are studied. The landforms include; plains, depression floor with low, moderately high and high lands, Mesa and plateau, and pediplains. Studying their morphological, chemical and physical characteristics, the soils were classified under the following taxa; Haplogypsids, Haplosalids, Calcisalids, Gypsisalids, Calcigypsisalids, Torriorthents and Torripsamments. Calcium and gypsum accumulations are found in saline soils in most of the soils. In the low lands, drainage may have serious problems. The presence of groundwater and the problem of drainage are common in most of the depressions. The challenge is to be aware of the problem and to design a proper and appropriate soil and water management system.

DEVELOPMENT AND EVALUATION OF A FODDER BEET CHOPPING MACHINE
The objective of the present work is to develop and evaluate fodder beet chopping machine to obtain beet sizes suitable for small ruminants feeding and to avoid clogging during chopping process. Experiments were carried out at Sakha Agriculture Research Center during winter season of 2009 / 2010 using fodder beet crop (Monovert variety ) to assess the effect of rotor speeds, beet feed rates and beet moisture content on chopper performance (machine productivity, chopping sizes, power requirement and energy consumed and chopping cost ).
Results indicated that, the optimum operation condition was obtained at rotor speed of 350 rpm, beet feed rate of 9.9 Mg/h and beet moisture content of 84.15% (w.b). Whereas, the minimum values of energy consumed of 1.411 and 0.748 kW.h/Mg were obtained under these conditions for original and modified machine, respectively. Also, an acceptable beet sizes of 25 and 56 % for < 2 cm however, they were 23 and 21 % for > 2 – 4 cm for the two proposed machines. Meanwhile, machine productivity of 6.278 and 9.165 Mg/h were occurred under the same conditions. Moreover, the cost calculations indicated that the original chopping machine costs about 1.46 times the modified machine.

SOME PHYSICAL AND CHEMICAL PROPERTIES AND STATUS OF NUTRIENTS AS AFFECTED BY SLOPE POSITION IN MARSA-MATRUH
The current study aims to study some soil physical and chemical properties and available nutrient content in relation to soil erosion. Five soil profiles were dug in Wadi-Madwar in Marsa Matruh. The name of soil profiles were represented (South Wadi-Madwar, Soil stone, Bir Haiyub,Elshiyab cemeter and El Qasr ). Soil profiles along the main slope inside Wadi-Madwar reflect the effect of water erosion process on soil properties with slope 122-4mm. The results can be summarized as follows:- Particle size distribution and soil texture class for soil profiles revealed that silt and clay fractions were gradually increased down slope and soil texture of Wadi-Madwar were sand, sandy loam and loamy sand. Values of gravel percentage were decreased with down slope. The changes in pore size distribution due to soil erosion were identical and revealed that values of slowly drainable pores (SDP) in the soil profiles under investigation were very small. Water holding pores (WHP) and fine capillary pores (FCP) values were increased with increasing the slope length to the sea direction. Field capacity (FC) and wilting point (WP) values in the soil profiles under study increased with slope length toward the sea and Hydraulic conductivity (K) values decreased down slope toward the sea. Soil bulk density value in the deep layer was slightly higher than of the surface layer, at the same time, soil bulk density values were higher beside the mountain and decreased gradually with slope length towards the sea. Total porosity values decreased in all profiles beside the mountain and increased with down slope. Soil pH values of all soil profiles ranged between 8.1 and 8.9 and reflect the alkalinity of studied profiles. EC values were low and decreased with increasing soil depth and ranged between 3.1 and 6.9. Average content of calcium carbonate tends to increase with soil depth and at the down slope. Organic matter content tends to increase with soil depth and at the down slope. Cation exchange capacity (CEC) was mainly correlated with the soil fine fraction content and it was increased at down slope. The contents of available N, P, K, Fe, Mn, Zn and Cu increased towards the down slope area.

IMPACT OF ADDITION OF SOME SOIL AMENDMENTS ON AVAILABLE NUTRIENTS IN SOIL AND SESAME PRODUCTIVITY GROWN UNDER SALINE CONDITION
Two field experiments were conducted at Sahl El-Tina at North Sinai Governorate in private farm in two successive summer seasons of 2009 -2010. The study was conducted to check up the effect of applying gypsum, sulphur and compost on availability of nutrients in soil and sesame productivity grown under saline soil condition. The seeds of sesame were Cv. (Shandawil 3). Application rates for gypsum and compost were 0, 2 and 4 Mg fed-1 but it was 0, 0.2 and 0.4 Mg fed-1 for sulphur. Addition was performed 30 days before sowing . Basial fertilizers were applied at the recommended doses ; and were applied in 3 successive doses.
The results showed that the application of high rate of all amendments led to decrease EC and soil pH. Available macro and micronutrients in soil were elevated with increasing the rate of application of gypsum, compost and sulphur. Compost treatment at 4 Mg fed-1 gave the highest seed yield and oil contents of sesame; compared to the zero level of amendments. Elevating the application rates of the studied treatments heightened the uptake of macro and micronutrients in the seed of sesame. Again compost treatment superimposed the other studied treatments. Consequently,it may be recommended to utilize 4Mg fed-1 of compost to have good and higher quality of sesame yield grown on salt affected soil.

STATUS OF SOME MICRONUTRIENTS IN HE NORTHERN WEST OF NILE DELTA, EGYPT
This work aims to evaluate the relations between total as well as DTPA extractable Fe, Mn, Zn and Cu and each of soil texture, CaCO3, organic matter (OM) and CEC of soils adjacent to lakes of Idku and Maryut in the northern west of Nile delta. Thirteen soil profiles representing the main types of soils both areas were examined. The obtained results could be summarized as follows: Total Fe ranged between 20000 and 43000 mg kg-1 while available Fe varied from 1.8 and 22 mg kg-1. Contents of both forms decreased with depth. Total Mn ranged between 500 and 2800 mg kg-1 while available Mn varied from 3.0 to 35.4 mg kg-1. Total Zn ranged between 75 and 275 mg kg-1 while available Zn varied from 0.2 to 4.6 mg kg-1. Total Cu ranged between 37.5 and 225 mg kg-1 while available Cu varied from 1.0 to 32.2 mg kg-1. Significant negative correlations occurred between total content of each of the studied micronutrients (Fe, Mn, Zn and Cu) and each of soil pH, sand %, gypsum % and CaCO3 % and also between available Fe and soil pH; between available Mn and each of soil pH, ESP and sandy %; between available Zn and each of soil pH and ESP; between available Cu and each of soil pH and sand %. Significant positive correlations occurred between total contents of the micronutrients (Fe, Mn, Zn and Cu) and OM % as well as clay; between available micronutrients (Fe, Mn, Zn and Cu) and OM %, clay % and CEC. The data of the statistical measures showed that, the highest values of weighed mean (W) of total Fe, Mn and Cu were found in the soil profiles of sandy beaches, while, the highest values of W of Zn total were found in the soil profiles of recent Nile Alluvial. The trend (T) indicates that some of the soil profiles were highly symmetric distribution with respect to Fe, Mn, Zn and Cu. The calculated values of specific range (R) of the total content of all micronutrients under study revealed that, the studied soils were composed from homogenous materials. The soil fertility of the studies available micronutrients (Fe, Mn, Zn and Cu) seemed to be more than the critical levels.
