A pot experiments was conducted at Dekrnis city, Dakahlia Governorate during the winter season of (2013/ 2014); to investigate the effect of some natural materials as a fertilizer and its effects on crops quality, yield and nutrients uptake of pea (Pisum sativum) variety of "master B".
Nine treatments were arranged in a complete randomized blocks, which were the simple possible combinations among four treatments of some natural materials and two rates of application as follows (phosphate rock (100 and 200 kg.fed<sup>-1</sup>), mineral sulfur ore (100 and 200 kg.fed<sup>-1</sup>), potassium rock (100 and 200 kg.fed<sup>-1</sup>) and feldspar (100 and 200 kg.fed<sup>-1</sup>).
Each treatment was replicated three times. Thus the total number of replicates were twenty seven included 3 replicates of control for the season.
<strong>The obtained results could be summarized as follows:</strong>
The mean values of yield (g.plant<sup>-1</sup>), weight of 100 seeds (g), N, P, K % and its uptakes (mg.plant<sup>-1</sup>) after 45 and 75 days from planting, N, P and K% and its uptake (mg.plant<sup>-1)</sup>by seeds of pea after harvest and seed quality as reducing sugar%, non-reducing sugar%, total sugar %, V.C (mg.100g<sup>-1</sup>) and protein % after harvesting were significantly increased with using these natural materials. After harvesting, the plants gave the highest values with adding sulfur ore.
The highest values of the mentioned parameters were obtained from 200 kg.fed<sup>-1</sup> compared to the 100 kg.fed<sup>-1</sup> and it had significant effect.
Under any level of fertilization with some natural materials, pea plants were superior with increasing the values of all aforementioned traits than those obtained from the untreated plants. The highest values of yield (g.plant<sup>-1</sup>), weight of 100 seeds (g), N, P, K % and its uptakes (mg.plant<sup>-1</sup>) after 45 and 75 days from planting, N, P and K% and its uptake (mg.plant <sup>-1</sup>)by seeds of pea after harvest and seed quality as reducing sugar%, non-reducing sugar%, total sugar %, V.C (mg.100g<sup>-1</sup>) and protein % after harvesting were connected with treatments receiving 200 kg.fed<sup>-1</sup> sulfur ore.

The integrated use of organic and inorganic fertilizers on the yield of potatoes was evaluated in a field experiment at newly reclaimed sandy soil at El-Kattaba Region El-Monofia Governorate-Egypt, during two successive years (growing seasons of winter 2011/2012 and 2012/2013). The organic sources used were farmyard manure, poultry manure and compost. These were integrated in different proportions with mineral nitrogenous fertilizer as ammonium nitrate to supply 120 kg Nfed<sup>-1</sup> N. All the organic fertilizers were applied at planting time and mineral fertilizer (ammonium nitrate) was applied as divided into 4 doses, the 1<sup>st</sup> dose was added after planting by 15 days and the other doses applied every 15 days. The results showed that integrated use in different proportion increased the plant height, number of stems, total chlorophyll, nitrogen concentration in potato tubers and protein content, but mineral nitrogen fertilizer individually gave higher values compared with the integrated organic and mineral nitrogen fertilizers. However, the maximum and minimum values of potato yield and nitrate content in potato tuber were obtained by application of poultry manure combined with mineral nitrogen fertilizer and organic nitrogen individually, respectively.Organic matter OF content in soil was increased in all treatments compared with sole mineral nitrogen fertilizer and contrary, the values of bulk density BD decreased generally. Therefore,the combined use of organic manure with inorganic fertilizer application was recognized as the most suitable way for ensuring high quantity and quality crop yield and reducing the harmful effects of using nitrogenous chemical fertilizers, but also for sustaining soil fertility status.

The present work introduces composite manufactured from grounded rice straw via addition urea-formaldehyde "UF" resin as a binding material. The different percentages of commercial urea-formaldehyde resin were used by weight as binder in manufacturing of the composite. The expansion percentage "E" (%), bulk density "Bd" (kg/m<sup>3</sup>) and thermal conductivity "k" (W/m.<sup>o</sup>C) of the manufactured composite affected by different content of binding material "Bm" UF resin (0, 20, 30, 40 and 50%), different formation pressure "FP" of (5.7, 12.4 and 18.5 MPa) and elapsed time (days) after releasing formation pressure. The results showed that expansion percentage "E" (%) increased with increasing of formation pressure "FP" and elapsed time (days) at different binding material "Bm" (%). The bulk density "Bd" (kg/m<sup>3</sup>) was higher at binding material percentages "Bm" of 50 % under formation pressures of 18.5 MPa, after 0, 7 and 14 days. The bulk density “Bd” (kg/m<sup>3</sup>) was lower at binding material percentages "Bm" of 0 % (control) under formation pressures of 5.7 MPa, after 0, 7 and 14 days. The thermal conductivity "k"(W/m.<sup>o</sup>C) decreased with increasing formation pressure "FP" and binding material percentage.

The present study was conducted to improve the managing of the irrigation regime to develop agriculture to be more efficient and sustainable. As the main scope of the study was to investigate the overall effect of deficit irrigation and planting methods on wheat yield and some water relations in North Nile Delta. Wheat was grown in an experimental field at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate(31° 05’ N latitude and 30° 56’ E longitude), Egypt. The treatments were arranged in a split-split plot design with four replicates. The main treatments were three planting methods of basin, furrow and bed. The sub-treatments were four levels of N fertilizer i. e. 60, 75, 90 and 105 kg nitrogen fed.<sup>-1</sup> . The sub-sub treatments were assigned by three levels of soil moisture depletion namely: 45, 60 and 75 % depletion of available water(AW). <strong>The main results in this study can be summarized as follows: </strong>
1- The highest and lowest average values of the wheat grain yield(2791 and 2698 kg fed.<sup>-1</sup>), water productivity WP (2.12 and 1.95 kg m<sup>-3</sup>) and irrigation water productivity IWP(1.45 and 1.17 kg m<sup>-3</sup>) were achieved with the bed and flat planting methods, respectively during the 1<sup>st</sup> growing season. The bed planting method increased water productivity(WP) and irrigation water productivity (IWP) by 8.71 and 23.9%, respectively compared to the basin planting method for the soil moisture depletion of 45% during the1<sup>st</sup> growing season. The 2<sup>nd</sup> growing season had the same previous trend
2- The bed planting method accomplished the lowest average values of irrigation water applied(1973 and 1983 m<sup>3</sup>fed.<sup>-1</sup>) and water consumptive use (1332 and 1335 m<sup>3</sup>fed.<sup>-1</sup>) while, the highest average values of irrigation water applied(2395 and 2409 m<sup>3</sup>fed.<sup>-1</sup>) and water consumptive use (1437 and 1442 m<sup>3</sup>fed.<sup>-1</sup>) were given with the basin planting method for soil moisture depletion of 45% in the two growing seasons. Using the bed planting method saved about 17.6% of irrigation water applied compared to the basin planting method.
3- The soil moisture depletion of 45% recorded the highest average values of wheat grain yield(2942 and 2969 kg fed.<sup>-1</sup>), WP (2.13 and 2.14 kg m<sup>-3</sup>) and IWP(1.36 and 1.36 kg m<sup>-3</sup>) while, the soil moisture depletion of 75% attained the lowest average values of wheat grain yield(2551 and 2574 kg fed.<sup>-1</sup>), WP (1.93 and 1.94 kg m<sup>-3</sup>) and IWP(1.25 and 1.28 kg m<sup>-3</sup>) during the 1<sup>st</sup> and 2<sup>nd</sup> growing seasons, respectively. However, deficit irrigation (irrigating the wheat crop at depletion 45% of available water) increased wheat grain yield, water productivity and irrigation water productivity by 15.3, 10.4 and 8.8% compared to irrigating the wheat crop at depletion 75% of available water.
4- Application of 90 kg N fed.<sup>-1 </sup>for wheat crop achieved the highest average values of wheat grain yield(3136 kg fed.<sup>-1</sup>), WP (2.28 kg m<sup>-3</sup>) and IWP(1.46 kg m<sup>-3</sup>) for 1<sup>st</sup> growing season. Application of 90 kg N fed.<sup>-1 </sup>for wheat crop achieved the highest average values of wheat grain yield(3136 kg fed.<sup>-1</sup>), WP (2.28 kg m<sup>-3</sup>) and IWP(1.46 kg m<sup>-3</sup>) for 1<sup>st</sup> growing season, whereas the minimum average values of wheat grain yield in the two growing seasons were obtained with the lower applications of N fertilizer level (60 and 75 kg fed.<sup>-1</sup>).
5- It is recommended to use the bed planting method and application of 90 kg N fed.<sup>-1 in addition to irrigation of the wheat crop at depletion 45% of available water</sup> to obtain the highest values of wheat grain yield, water productivity (WP) and irrigation water productivity (IWP) in addition to save about 16.9 % of irrigation water applied.

This investigation was mainly carried out to develop and evaluate a stationary environmental cab with effective control techniques. Optical particle counters were used to measure the particulate matter that is 2.5 micrometers (PM<sub>2.5</sub>) aerosol number concentration, mg/m<sup>3</sup> inside and outside the cab. The ratio of the two measurements (i.e., protection factor = outside concentration / inside concentration) was used to calculate how efficient the tractor cab was at removing aerosols, then Inverted these protection factors termed aerosol penetration. Testing was conducted to evaluate compliance with American Society of Agricultural Engineers Standard S525 [ASAE, 1997], and air quality measurement, (Temperature,°C and humidity,%). In the stationary test, the tractor’s cab is isolated by glass wool and placed in a 25m<sup>3</sup> volume of enclosed testing chamber. Aerosol, generated by burning incense sticks. Experiments were done under four parameters namely three different modes of aeration and filtration systems in insulated cab included, (fresh air mode, re-circulation mode and evaporative cooling mode), four different fan air speed of (1.8, 2.1, 2.5 and 3 m/sec.), two different cab position are used (In-cab and out-cab) and sixty levels of times (1, 2, 3, 4, …and 60 seconds) for each run of optical particle counter) & (Seven levels of 0, 5, 10, 15, 20, 25 and 30 minutes for each reading of air quality measurement. The obtained results showed that the best results of PM<sub>2.5</sub> concentration for inside cab, was 3.3 mg/m<sup>3</sup>, the maximum values of Protection factors of filter inside cab was record 87, while aerosol penetration through filter inside cab, was record (1 / 87) = 0.0115, and the efficiency of filter with cab was 98.97%, obtained with fresh air mode in-cab at fan air speed of 1.8 m/sec., although getting the best result of the differences in temperatures in-cab, 7 °C, when using the cooling system evaporative, they recorded an increase of undesirable values humidity differences, (DRH), 11.7 %, with increasing the speed of the air fan because of the increasing saturation of the air spray of water used in the system.

A lysimeter experiment was carried out in the year 2012 at Sakha Research Farm Kafr El-Shaikh Governorate. The experiment aimed to study the effect of integrated use of ammonium sulphate (AS-N) and aqueous rice straw extract (RSE-N) as nitrogen sources on the yield (quantity and quality) of jew<sup>,</sup>s mallow and spinach crops in addition the quality of leached drainage water. Ammonium sulphate (AS-N) and (RSE-N) were combined in away to supply the recommended N-dose for experimental crops from both sources in (0:0) T1; (100:0) T2; (75:25) T3; (50:50) T4; (25:75) T5 and (0:100) T6 ratios arranged in a (RCB) design with three replicates. The results indicated that the highest jew<sup>,</sup>s mallow fresh yield (1583 g lysimeter<sup>-1</sup>) was recorded with (AS-N 50%) + (RSE-N 50%) treatment, while the highest spinach fresh yield (1405.66 g/liyzimeter) was obtained under T2 (100:0). On the other hand, the level of nitrate either in crop leaves or drainage water was greater in treatment with T2 (100:0) ratio. Nitrate content (NO3-N) mg kg<sup>-1 in jew,</sup>s mallow leaves reached 1.39 > 1.20 >1.16 >1.15 > 1.11 fold for treatments (100:0 AS-N), (75% AS-N +25% RSE-N), (100% RSE-N), 25% AS-N +75% RSE-N), and (50% AS-N + 50% RSE-N), respectively, compared to that under control T1 (0:0). For spinach leaves reached 4.15 > 2.57 > 2.43 > 2.09 > 1.77 fold for treatments (100:0 AS-N), (75% AS-N +25% RSE-N), 25% AS-N +75% RSE-N), (100% RSE-N) and (50% AS-N + 50% RSE-N), respectively. Under all fertilizer treatments, the content of nitrate in plant leaves or drainage water were lower than the published maximum permissible level to cause humans health hazard.

Two field experiments were conducted in Galbana village, North Sinai Governorate during two winter seasons 2011/2012 and 2012/ 2013, to evaluate the environmental effect of mineral nitrogen fertilizer rate, compost and bio-fertilizer on some soil properties and sugar beet productivity under newly reclaimed saline soil.Theseeds of sugar beet (<em>Beta vulgaris</em>) variety Loilwere inoculated with <em>Rhizobium radiobacter</em> strain (salt tolerant PGPR). Results indicated that the soil pH was not significant as affected by bio-fertilizer or compost alone or in combination with different rates of mineral nitrogen fertilizer. The soil salinity decreased with increasing rate of mineral nitrogen combined with bio-fertilizer or compost. The relative increases of soil available N content in soil due to mineral nitrogen fertilizer; compost and bio-fertilizer after sugar beet cultivation, followed the descending order: bio-fertilizer> compost > mineral N as compared with initial soil for available N content. The relative increases in both P and K followed the descending order: compost > bio-fertilizer > mineral N fertilizer as compared with soil initial contents of P and K. The available micronutrients ie Fe, Mn, and Zn in soil were not significantly affected by the different fertilization treatments in both the first and second seasons. Also, available Fe was not significantly affected with rate of the used fertilizers whereas the effects of different rates on the available contents of both Mn and Zn were significant in the second season, however in the first one such rates were of significant effect of Zn only. The interactions among bio-fertilizer, compost and mineral nitrogen rates were of significant effects on Mn content in soil in both seasons whereas such an effect was significant on Fe in both seasons and Mn in the first one. The highest mean values of fresh and dry root yield, sugar yield, total soluble solids (TSS), purity and sucrose were achieved due to treating soil with bio-fertilizer together with the mineral nitrogen fertilizer. The highest values of N (1.14 %) concentration in root was observed at soil treated with compost plus 100 kg mineral N fertilizer, while the maximum values of P and K concentration (0.28 % for P and 1.29 % for K ) was observed as affected by bio-fertilizer plus 100 kg mineral N, respectively. On the other hand, the effect of all treatments tested on Fe, Mn and Zn concentration in root of sugar beet was non significant. As a conclusion, bio-fertilizer and compost application in sugar beet could increase characteristics of sugar beet root and reduced consumption of mineral nitrogen fertilizer and successfully reduced the hazard effect of soil salinity condition.
