The ultimate goal of this study is to find out the most suitable combinations of adjacent crops that reduce house sparrows damage. The experiments were established using single and double combinations of four wintery crops. Namely, soft wheat, hard wheat, sunflower, and barley. The double cultivations were designed by growing varying crops nearby a fixed one crop as follows 1- (soft wheat alone), (soft wheat- near sunflower), ( soft wheat near – barley), and (soft wheat near – hard wheat) 2- (barley alone),(barley- near soft wheat), (barley near - hard wheat), and (barely- near sunflower) 3-(hard wheat alone),( hard wheat- near barley), (hard wheat near – sunflower), and ( hard wheat near – soft wheat). The experimental results revealed the following; the damage percentage of house sparrows to soft wheat was 25.9 %, but when grown nearby sunflower, barley, and hard wheat the soft wheat damage reached 5.9 %, 25.9 %, and 33.3 %, respectively. In single cultivation of barley, house sparrows damage was 8.2 %, but when grown nearby soft wheat, hard wheat and sunflower, the barley damage reached 13.5 %, 1.7 % and 1.2 %, respectively. Single cultivation of hard wheat house sparrows damage was 0.0 %, while when grown adjacent to barley, sunflower, and soft wheat, the hard wheat damage reached 0.0 %,0.0 % 3.8 %, respectively. In single cultivation of sunflower, house sparrows damage was 20.2 %, while when grown nearby, barley, soft wheat , and hard wheat, the sunflower damage reached 9.5 %, 10.2 % and 36.3 %, respectively. Results obtaine from this study revealed the following: 1- sunflower could be grown nearby barley and / or soft wheat, but away from hard wheat; 2- barley could be grown nearby sunflower and /or soft wheat, but away from hard wheat; 3- soft wheat could be grown nearby sunflower, but away from hard wheat; 4- hard wheat could be grown nearby barley or sunflower, but away from soft wheat. These concomitant cultivations can be successfully practiced be small growers to protect their main crops from house sparrows attack naturally and effectively without using any pest control compounds and without any extra costs as well.

The traditional feed industry is based on concentrated raw feed materials and may be rich in energy or protein. The feed is a homogeneous mix of raw feed materials with some mineral salts and may be supplemented by some food additives such as vitamins, antibiotics, urea, antioxidants etc. In a soft or treated with steam and molasses and pressed into cubes, cylinders, granules or other forms. In view of the State's attention to livestock, in addition to increasing the demand for animal products for higher living standards and increased awareness of food, the feed industry is expected to rise in the next few years. The problem of the study is limited to the impact of the agricultural production market in Egypt on many local and international economic variables, which causes fluctuations in the supply and demand of these products in the local market and foreign markets. Egypt suffers from a deficit in its trade balance of agricultural inputs. In this deficit,  as well as the decrease in the amount of concentrated fodder, mainly maize and the quantity produced from processed fodder, which also depends mainly on maize, especially poultry feed, which forms yellow maize 75% of the ingredients and therefore. The burden on the trade balance increases, especially as the dollar rises. Therefore, the study aimed to identify the economic indicators of the processed animal feed and poultry in Egypt. The study is based on the use of descriptive statistical methods (statistical measures) and quantification of averages and percentages as well as the work of the model of the variables studied and forecasting. The current model consists of four equations. The first is the formula of local production of processed feeds. Processed, the third equation is the formula of imports of processed feeds, the fourth equation is processed feed exports.

During summer seasons of 2015 and 2017, a field experiment was conducted at the Research and Experimental Station (30°19′ N, 31°16′ E), Faculty of Agriculture, Ain Shams University at Shalakan, Kalubia Governorate, Egypt, to investi-gate the effects of combinations between hydroxyl apatite nanoparticles (0, 3, and 6 kg/fad) and cal-cium carbonate nanoparticles (0, 500g/fad) as nano-fertilizers under irrigaton intervals, (irrigation every 2 or 3 weeks whereas irrigation every 2 weeks as a recommended practice) on growth of soybean plants. Irrigation intervals had statistically significant effect on plant height (cm), number of branches per plant, number of leaves per plant, leaf area index, number of pods per plant, number of root nodules per plant, root dry weight per plant, stem dry weight per plant, leaves dry weight per plant and pods dry weight per plant. These results were fairly true in the two studied seasons 2015, 2017 and combined result. plant height, numbers of branches per plant, numbers of leaves per plant, leaf area index, number of nodules per plant and number of pods per plant of soybean plants which treated with 500 g/fed surpassed untreated plants in the two studied seasons 2015, 2017 and com-bined. Soybean plants treated with 6 kg hydroxyl apatite nanoparticles per feddan out-numbered other plants in its numbers of leaves per plant, leaf area index, number of root nodules per plant and number of pods per plant in the two growing sea-sons 2015, 2017 and combined data. Results showed that normal irrigation x 500g/fed calcium carbonate nanoparticles x 6kg/fed hydroxyl apatite nanoparticles was the effective combination for producing the highest values of plant height (cm), number of branches per plant, number of leaves per plant, leaf area index, number of pods per plant, number of root nodules per plant, root dry weight per plant (g), stem dry weight per plant (g), leaves dry weight per plant (g) and pods dry weight per plant (g). There weren’t significant results be-tween plants treated with nano-mineral fertilizers under irrigation every 3 week and plants untreated but irrigated every 2 week in all growth traits, which reflect appositive result of this chemical substance in mitigation harmful effect of water shortage in season 2015, 2017 and combined data.

The purpose of this study is to improve texture, flavor and overall quality of low-fat white soft cheese. Using sodium caseinate (SC) and / or butter milk powder (BMP) in different ratios. Buffalo’s milk was divided into two portions. The first portion was standardized to 3% fat and served as a control (1). The second portion was standardized to 1% fat and sub divided into five parts, the first part was served as control (2), the second part fortified with 2% SC (T1), the third part fortified with 2% BMP (T2), forth part fortified with 1% SC + 1% BMP (T3) and fifth part fortified with 0.5% SC + 1.5% BMP (T4). All cheese treatments stored in salted whey (5% NaCl) at 5±2°C up to 3 months. The results indicated that, control (2) had obviously lower moisture content than control (1). Addition of sodium caseinate and / or butter milk powder to cheese milk led to an increase in moisture content of resultant cheese compared to control (2). A slight increase was observed in total nitrogen % of low-fat all soft cheese treatments versus control (2) being more obvious in T2 and T3. Low-fat soft cheese treatments were characterized by higher soluble nitrogen % than control (2). Moreover, the results showed also that, replacing of milk fat with SC + BMP caused a decrease in hardness, adhesiveness, springiness, chewiness and gumminess in fresh cheese compared to control (2). Sensory properties of Low-fat soft cheese were highly improved by adding SC + BMP to cheese milk as a fat replacer. Low-fat soft cheese was most preferable in T3 with adding SC + BMP (1:1), those improved the compositional as well as the organoleptical properties, especially its body and texture of low fat brined soft cheese after 90 days of cold storage.

Due to deleterious impacts of broomrapes against the host plants, its combating is ‎essential for sustaining crop productivity. Thus, two–year field trail was conducted at ‎El Nubaria experimental farm, National Research Centre, Egypt, on two faba bean ‎genotypes (Misr–3 and Sakha–1) to investigate the importance of butyl–iso–butyl ‎phthalate as an activator for broomrape germination in comparison to glyphosate and ‎unweeded. Findings revealed that glyphosate in 2015/16 and 2016/17 seasons in ‎addition to butyl–iso–butyl phthalate in 2016/17 season caused significant reductions ‎in broomrape biomass and numbers of broomrape–infected faba bean plants plot−1 ‎compared to the unweeded. Plots of Misr–3 genotype treated with butyl–iso–butyl ‎phthalate in both season as well as plots of Misr–3 or Sakha–1 sprayed by glyphosate ‎in the first season achieved the maximum seed yield of faba bean. Since butyl–iso–‎butyl phthalate exhibits suicidal germination of broomrape seeds, it can be exploited ‎as an effective and helpful tool in integrated management programs of broomrape in ‎faba bean fields. ‎ Due to deleterious impacts of broomrapes against the host plants, its combating is ‎essential for sustaining crop productivity.

Twenty-one new promising lines in addition to four standard cultivars of snap bean (Phaseolus vulgaris L.) were evaluated under eight environmental conditions (four sowing dates in two seasons of 2015/2016 and 2016/2017). A randomized complete block design (RCBD) with three replicates was used for each sowing date at Barrage Horticulture Research Station (BHRS), Qalubia Governorate, Horticulture Research Institute (HRI), Agricultural Research Center (ARC), Egypt. Data were recorded for some traits i.e., number of days to flowering, pod length, pod diameter, fiber content, total green yield and rust disease severity. The results showed that the linear response of environments was highly significant for all studied characters, indicating the differences between environmental conditions and their considerable influence on these traits. Mean squares of genotypes (G) were highly significant for all studied traits, suggesting the presence of wide range of differences between studied genotypes concerning all investigated traits. Mean squares of the other main sources of variation, i.e., years (Y) and sowing dates (D) were also highly significant for all traits except year for total green yield/feddan trait. The mean square due to environment + (Genotypes × Environment) was significant for all studied traits, indicating that there was a considerable interaction of genotypes with environmental condition in different eight environments. Significance of Genotypes × Environment (linear), reveals that genotypes differed in their considerably across different environments. The linear response of environments was highly significant for total green yield trait, indicating that genotypes differed in their regression on the environmental index. The results of stability analysis conclude that the six new lines G1, G2, G3, G7, G10 and G18, were the most stable genotypes, which gave the maximum total green yield overall the eight studied environments and were adapted to environments for total green yield. It is evident that these genotypes could be used as stress tolerant genotypes under stressed environments.

Abstract: The present study was carried out from November (2015) - October (2017) to determine the toxicological effects of pesticides exposure on agricultural application workers. Blood samples of the investigated workers were collected from Giza, Qalyubiyah and El-Buhayrah Governorates, Egypt. Thirty male individuals represented pesticide application workers were involved from the three governorates. Also, 25 male individuals (aged 18-55 years) were selected randomly from Cairo Governorate to represent the unexposed (control) group. Ten ml of blood sample per individual was collected and serological analysis for hematological (RBCs, TLC, Hb, PCV, MCV, MCH, MCHC), biochemical (ALT, AST, total protein, urea, creatinine and uric acid) and oxidative stress (GSH.R, MDA and AChE) parameters were carried out. Results: About 53% of workers involved was with an average level of education, between 18 and 35 years of age (57%), working in their field for 6 to 10 years (40%), about eight hours a day for six days a week on average (67%). Hb, MCH, MCHC, ALT, AST, AlP, TP, urea, creatinine and MDA were increased significantly by 5.58, 9.23, 3.75, 55.49, 42.44, 30.07, 6.83, 49.33, 25.48, and 133.02% respectively. While the levels of Alb, GSH.R and AChE activity were significantly decreased by 14.51, 8.33 and 21.04% respectively. a significant positive correlation between exposure duration and ALT, AST, creatinine, urea and MDA. While, there were significant negative correlations between exposure duration and total protein, alkaline phosphatase, AChE Activity, GSH.R, RBCs, Hb, PCV, MCV and MCH. Conclusions: Increasing of pesticide application workers vital parameters gives an indication of the occurrence of various health consequences due to chronic exposure to pesticides. These results can be explained by the fact that the negligence of workers in following occupational safety and health measures from wearing protective tasks, not smoking, drinking and eating during the application of pesticides, resulting from the low awareness of workers about the risks of the materials dealt with and the decrease in their educational and cultural level increases the chances of exposure to the pesticide. On the health of the worker.

Pot experiments were carried out using sand (collected from Ismailia ARS), in the greenhouse to study the effect of biochar application, on K and P release from their natural bearing minerals i.e.,K- feldspar and rock phosphate and\or bentonite on some growth of maize plants parameters, their P and k uptake and the soil available P and K. sixty three pots ever filled with sand(10 kg each biochar was added to all pots expect control at rates 0,1.5 , 3 ton per fed. The studied mineral are K feldspar and rock phosphate as source of K and P respectively. Bentonite was also studied because it is the most common mineral used for reclamation of sandy soil .Each mineral was added at rate of 0,1.5, 3 ton / fed the pots are as follow : biochar alone , biochar + K feldspar and biochar +bentonite and biochar and rock phosphate . maize was planted as the common way in which maize seed 6 grains for each pot inoculated with P and K solubilizing bacteria were planted . the usual N fertilizer (NH4 )2SO4 200kg /fed and irrigated as needed . Maize grow parameter i.e plant height and dry weight of maize plant were measured after 2 months of plantation . K and P as well as their uptake were measure. Results revealed that, the use of biochar at 3 tons fed-1 in combination with 3 tons of any of feldspar, bentonite or rock phosphate enhanced significantly growth parameters of maize plants compared to the control treatments .The highest values plant length and dry matter were were 89.00 cm, 11.4 g pot-1 against 36.6 cm and 2.8 g pot-1 for the control treatments., same treatments increased significantly P and K uptake of maize plants and the soil available p and K compared to the control treatments. The highest significant values in P uptake were 22.5, 18.3 & 16.7 mg plant-1 for the treatments (3 tons fed-1)of biochar with either 3ton rock phosphate ,3ton bentonite or 3 ton K-feldspar .while K uptake were 63.9, 61.8 & 60.1 mg plant -1 for biochar ( 3 tons fed-1 )with bentonite (3 tons fed-1 ), feldspar (3 tons fed-1 ) and bentonite (1.5 tons fed-1 ). Regarding available P the highest obtained values were 49.3 mg Kg -1 for 3 ton biochar + 3ton rock phosphate , 24.1 mg Kg -1 for 3 ton biochar + 1.5 ton bentonite and 24.0 mg/ kg-1 for 3 ton biochar + 1.5 ton K- feldspar. Increase either K- feldspar or bentonite to 3 ton had negative effect on available p .

The present study was suggested as an attempt to investigate the effects of Pink Pigmented Facultative Methylotrophic Bacteria (PPFM) dipping and foliar spray on vegetative growth and yield of eggplant (Solanum melongena L.). Field experiments were carried out during the summer seasons of 2014 and 2015 at the Experimental Farm, Faculty of Agriculture, Ain Shams University. The vegetative growth of eggplant responded positively to dipping seedlings in PPFM which gave the highest values of growth parameters, i.e. number of leaves per plant, leaf area, nitrogen & potassium concentration in leaf and total protein in fruit, in the two seasons as compared with control (dipping in water). The application of PPFM as foliar spray, increased significantly plant growth (plant length, leaf number, potassium concentration in leaf, vitamin "C" in fruit and total yield per plant) in the two seasons as compared with the other studied foliar application treatments. The interaction between dipping seedlings in PPFM and PPFM foliar spray with all concentrations gave synergistic effects on growth parameters and yield components of eggplant, during the two growing seasons as compared with either individual foliar application or control plants.

The experiments were conducted to evaluate the effect of mycorrhizae (Glomus sp. and Gigspora sp.) application on the vegetative growth and yield of tomato plants (Alisa cultivar), and its relevance to the mineral fertilizers requirements as NPK during the seasons of 2015/2016 and 2016/2017. The experiments were conducted at Baloza Research Station, Desert Research Center, North Sinai Governorate, Egypt. The experimental design was a randomized complete block design with three replicates, every replicate included 4 treatments (75 and100% of the recommended mineral fertilizer only or combined with the mycorrhizae treatment). The results showed that mycorrhizae application significantly increased the vegetative growth characters of tomato plant such as plant height, number of shoots, number of leaves, stem diameter, fresh and dry weights and yield. There were no significant differences in the vegetative growth characteristics of tomato plants receiving 75% of mineral fertilizers in addition to mycorrhizae application as compared with plants receiving 100% of mineral fertilizers only, except for the fresh weight of plants. The plants were received 100% of the recommended mineral fertilizers combined with mycorrhizae treatment gave the highest values of vegetative growth characters and yield. Therefore, we recommended that, using of mycorrhizae could be affective to maximize the utilization of mineral fertilizers, in addition, the mycorrhizea is ecofriendly, economically and consid ered as one of the most important bio-fertilizer resources.
