The objective of the present work was to develop and evaluate aeration machine for turfgrass to make under Egyptian condition. The aeration machine was evaluated versus two holes density (24 and 48 hole/m2), two hollow tine diameters (2.5 and 3 cm), three average depths of aeration (4, 6 and 8 cm) and four forward speeds (2, 2.7, 3.6 and 4 km/h). After 7 days from aeration operation the results showed that the lower bulk density and penetration resistance values was 0.960 g/cm3 and 154 kPa, respectively opposite it the higher porosity and void ratio values were 65.09% and 1.865, respectively at 48 hole/m2 holes density, 3 cm tine diameter, 8 cm depth of hole and forward speed 2 km/h comparing with control 1.271 g/cm3, 337 kPa, 53.79% and 1.164 for density, penetration resistance, porosity and void ratio, respectively. The higher actual field capacity was (0.941 fed/h) at 24 hole/m2 holes density, 2.5 cm tine diameter, 4 cm depth of hole and forward speed 4 km/h. The lower energy required was 16.223 kw.h/fed, at 24 hole/m2 holes density, 2.5 cm tine diameter, 4 cm depth of hole and forward speed 4 km/h.

This study include 32 species all belonging to the genus Euphorbia ( Euphorbiaceae) .These samples collected from different floristic regions in Egypt. The anatomical studies occur on the stems of the plant samples and the characters are recorded comparatively for each species. The observations showed that the stems are mostly angled, the epidermis is often simple with one layer, the cortical layers of many species contained storage parenchyma, cells like palisade tissue. Transfer tissue, air cavities and idioblast also calcium oxalate observed in the cortex. The pith is solid in most samples and hollow in a few species.

This research was carried out to study the potential use of by-products of biogas production, i.e. biogas slurry (BS) generated from cattle dung, as nutrient sources in agriculture. The pot trials were conducted under green house conditions on the growth, yield of snap bean and their chemical composition. Some soil enzymes, i.e, nitrogenase and dehydrogenase were determined, also available P. Snap bean was fertilized with various sources of phosphate fertilizers, calcium superphosphate or rock phosphate at the rate of 30 kg P2O5/fed combined with BS.
Results showed that vegetative growth parameters significantly increased by using BS and RP or SP for two used varieties, applying of 10 m3BS + 30kg P2O5/fed as SP gave the maximum values of vegetative growth parameters for Paulista variety. For other variety, Xera, 10 m3BS + 30kg P2O5/fed as SP led to the highest plant height. While 2.5 m3BS + 30kg P2O5/fed as RP gave the highest values of plant dry weight and No of branches. With respect to yield and its components, pods weight /plant and pod length of Xera cultivar significantly increased over control, also pods weight /plant for another cultivar significantly increased over control as a result of using BS and various sources of P fertilizer
Regarding the leaves chemical composition, using Bs combined with RP or SP caused significant increase of N, P, K as macronutrients, where 10 m3BS + 30kg P2O5/fed as RP gave its highest values for two used varieties. Micronutrients Fe, Mn, Zn and Cu significantly increased over control. Applying of rock phosphate (RP) with BS was more effective on most of these nutrients than super phosphate (SP) + BS for the two cultivars used.
For the pod chemical composition which significantly increased, N,.K and total protein of Xera variety reached to the maximum values by using SP + 10 m3BS. While the highest value of T.P% obtained by RP +10 m3BS. Fe, Mn and Zn concentration (ppm) enhanced by using RP +10 m3BS. For Paulista cultivar, T.N, T. protein and Fe increased up to the greatest values by RP +10 m3BS, while T.P and Mn reached to the maximum values by using SP +10 m3BS.
With regard to biological activity and available phosphorus, data showed significant increases by the treatment under this study. Clearly applying RP along with 10 m3BS gave the highest values of dehydrogenase, nitrogenase enzyme activity and total count of bacterial more than those obtained by SP +10 m3BS, while the best results for available P were obtained by SP +10 m3BS. Accordingly, this study ensured that the use of rock phosphate with biogas slurry may be recommended as a substitute for super phosphate with biogas slurry in snap bean production.

This study was carried out during two successive seasons 2014 and 2015 for evaluating the effect of inoculation with Bradyrhizobium sp, Bacillus megaterium, Bacillus circulans, Glomus macrocarpum instead a part of chemical fertilization in the presence of biocontrol agent i.e., Pseudomonas fluorescens on some microbial enzymes activity, growth characteristics, some biological constituent as well as yield and its components for optimal nutrition and some attributes of cowpeas. Obtained data showed significant increases of dehydrogenase (DH), nitrogenase and phosphatase activity in both seasons using of the combination of biofertilization and chemical nitrogen fertilization. Moreover, the values of NH4-N, NO3-N, available-P and soluble-K were the highest records with dual application of biofertilizers and half dose of chemical fertilization. Concerning, vegetative growth parameters and total yield, NPK-microbial inoculants combined with NPK-mineral fertilizers had the highest values. The results of this study suggest that, it may be replaced the mineral fertilizers by biofertilizers, even partially, to produce a better food and such integrated nutrient management program should be followed to produce the highest yield of cowpea.

Papilionoideae (Faboideae)isthe largest subfamily inthe family Leguminosae. The study occure on some trifoliate species belonging to this subfamily .The investigations include the morphological characters of the vesgetative organs(stems and leaves) beside the micromorphological features obtained from the examinations of the leaflets epidermis (cell walls shape,trichomes forms, stomatal types and the precense or absence of oxalate crystals) .Also the study includes floral aspects and the type and shapes of fruits and seeds.

This study is conducted on 8 genera belonging to Lamiaceae. The samples are collected from different areas in Egypt. The study is done on the morphological characters of roots, stems, leaves or leaflets, flowers, inflorescences and fruits. Also the anatomical characters of roots, stems and leaves are studied. The results are recorded in the form of comparison among the examined plants. Most of the examined plants are herbs as inMoluccellalaevis butVitexagnus – castusisshrub and Tectoniagrandisis tree. The aerial stems are present in all examined plants, while the rhizomatous subterranean stems are present in Menthapiprata. The anatomical study shows that theoutline shape of cross section is 4- angular in all stems of the examined plants except Teucriumpoliumis rounded
