Agricultural mechanization is considered one of the most important agricultural technological methods for making fundamental changes in the agricultural sector. Therefore, Egypt has worked on two main axes: horizontal and vertical expansion, using modern agricultural technology, which is one of the important tools of development in the agricultural sector because it has a positive impact on vertical expansion. The study aimed to review the current state of agricultural mechanization at Egypt level and the governorate of Sharkia governorate to find out the availability of modern agricultural machinery and equipment and study the relations of substitution and complementarity between these machines and each other and the relationship of these machines to the crop area and productivity of wheat in Egypt. The most important results were: The number is increasing of tractors, ploughs, shooters, seeders irrigation machines, hoe machines, pesticides sprayers, harvesters, threshing machines in Egypt and Sharkia governorate, The increase in the number of prisons in Egypt and the decrease in the Sharkia of seed dill, and the decrease in the number of transplanters in Egypt and Sharkia governorate. The relationships between agricultural machinery (tractors, ploughs, irrigation machines, hoe machines, pesticides sprayers, harvesters, and, threshing machines) are both linear and statistically significant. This means that there is a complementarity between these machines and each other, As well as relations between the agricultural machinery and the seeders, seed drill and transplanters where the relationship either be positive but they are significantly less than the equivalent of other machines are either positive or negative, but not statistically significant and therefore it has nothing to do with the other. There is no statistically significant relationship between the productivity of wheat in Egypt and Sharkia governorate and the machinery (tractors, ploughs, seed drill, hoe machines, harvesters, threshing machines). Decreased total average area per tractor for wheat crop in Egypt and Sharkia governorate. There was no statistically significant relationship between the average crop area for each tractor and the production of wheat crop in Egypt. In Sharkia governorate, the relationship is inverse and statistically significant. There is a statistically significant correlation between the average area per tractor for wheat yield in Egypt and the average area per tractor for wheat crop in Sharkia governorate. There was no statistically significant correlation between the number of tractors and the productivity and the average yield area per tractor for wheat yield for both Egypt and Sharkia governorate. The agricultural mechanization is still in its early stages, economic relations either do not exist or take different signals. The statistical significance of the development of the number of machines at Egypt level or the Sharkia governorate for the first strategic crop in Egypt is not proven. Hence, agricultural mechanization in its broad sense is the use of modern technology in increasing production Which has not yet been achieved and hopes and efforts are required to pursue better policies to achieve the desired goals

Two hundred multiparous Holstein dairy cows post-partum were randomly assigned into two groups. The first group (control, n=100) was fed total mixed ration (TMR) without a supplement of liquid probiotic enzymes. The second group (treatment, n=100) was fed TMR supplemented with a commercial probiotic (ZAD) prepared by Bactizad company, Cairo, Egypt. at the rate of 10 ml/head/day. According to the guide of the manufacture for 12 weeks ZAD was added and mixed to the TMR at the time of feeding once per day. Each group was placed in a shaded pen equipped with free stalls. Results obtained showed that Milk yield increased significantly from 39.57 kg/day for control group up to 41.73 kg/day for treated with ZAD group. Fat and protein milk percentage tended to be improved due to treated with ZAD but the difference was not significant. Lactose percentage was affected positively and significantly by treated of ZAD, lactose percentage was 4.79 for control group and 4.83 for ZAD group. Serum total protein increased significantly from 11.52 (g/dl) for control group up to 11.85(g/dl) for treated ZAD group. Albumin was significantly higher in control group. Results indicated that blood urea concentration in treated group being 34.77 (mg/dl) and for the control group 33.91 (mg/dl), was significantly higher. Alkaline phosphates increased significantly in treated group from 21.105 U/l for control group up to 26.92 U/l for treated group. Cholesterol concentration was reduced significantly due to treatment from 240.98 mg/dl in control cows to 190.13 mg/dl in treated cows. Triglycerides concentration declined significantly due to treatment of probiotic ZAD. In control cows triglycerides concentration was 27.871 (mg/dl) and treated cows was 20.9781 (mg/dl). T3 concentration increased significantly as a response to treatment by probiotic ZAD. T3 concentration was 117.29 ng/dl in treated group and 62.38 mg/dl in control group.

This research is aimed at investigating the evolution of the food gap of faba beans and its underpinning factors. Faba beans constitute the most basic foodstuff Egyptian diet. Among all legumes the beans crop occupies the largest acreage and provides the beans crop occupies the largest acreage and provides the largest volume of production. However, domestic production of faba beans is increasing falling short of its ability to meet the domestic consumption requirements. That is the food gap of faba beans is widening year after year. In fact the gap increased substantially from 73 thousand tons in year 2000 to about 650 thousand tons in 2016. By an increase of about 891%, this research is intended to study the evolution of the food gap of faba bean in Egypt During the period (2000-2016).

The present work is aimed to isolate, purify, identify a newly isolate Rhizobium fabae from different regions in Egypt then, produce and optimize Poly-β-Hydroxybutyrate polymer (PHB) production by the selected isolate Rhizobium fabae F44 using a statistical approach of response surface methodology (RSM). Rhizobium fabae F44 isolate was picked up from Sharkia Governorate in Egypt and then identified by the 16SrRNA gene as Rhizobium fabae. Eleven different variables which affect the production of PHB polymer were screened by Plackett–Burman statistical design approach. Maximization of PHB production was adjusted by the terms of The Face Central Composite Design (FCCD) of RSM and assessed at three coded levels (–1, 0, +1). One way Anova was used to statistically analyze all obtained results in relation to post hoc multiple comparison analysis performed by Tukey’s HSD. Appulses of nutritional and physical factors (two carbon sources, two nitrogen sources, mineral salts, pH, temperature, incubation time, inoculum size and agitation rate) were studied using Plackett-Burman design method. 58 isolates were obtained from the different 9 governorates with 100 % infection plant technique. The 16SrRNA showed a similarity of 99.56 (%) to Rhizobium fabae F44. Out of all tested significant media components, sucrose, yeast extract, agitation rate had the highest significant effects on the response as for PHB production, with confidence level > 98% and were further optimized using FCCD. Predicted Maximum PHB production was observed as (78.51%) which in near the mid-point (0) values (concentrations) of sucrose which reached (25 g/l) and yeast extract of (0.5 g/l) for 48 hrs. at 150 rpm agitation rate. The observed experimental value reached 87.5u/ml was very close result to the predicted one validating the model. So, Response Surface Methodology is an effective statistical approach which can substitute the use of one variable at a time approach due to its adequacy and efficiency to optimize PHB production by Rhizobium fabae F44.
