This work was conducted to investigate the effect of foliar sprays of kaolin and Calcium Carbonate (5%) on vegetative growth, blooming, fruiting aspects and characteristices, fruit physical and chemical contents of “Aggizi Shamy” and “Picual” olive cvs. throughout two successive seasons (2011and 2012 seasons). Trees were 15-year-old and planted at 6X6 m. apart in a sandy soil in a private orchard at AL-Khatatba, Minufiya Governorate. The study aims at improving growth and productivity of olive trees. Data revealed that kaoline on mid Jan. increased significantly the number of leaves of Aggezi Shamy in both seasons, whereas kaolin added on mid Dec., Jan, and Feb. gave the same effect on Picual cv. . As for the leaf area of Aggezi cv. was influenced significantly by kaolin on mid Feb. in both growing seasons, while as the same treatment on mid Dec. increased leaf area significantly in picual cv.. Concerning the internode length kaolin on mid Dec. gave the highest significant values compared to the control and other treatments in both cultivars in both seasons. Calcium carbonate in mid dec. and kaolin in mid Feb increased significantly the sex ratio values of both Aggezi and Piculal cvs. in both seasons, respectively. Kaolin in mid Dec. increased significantly number of fruit set (%), number of fruit per meter and yield (Kg/tree) of Aggezi and Picual cvs. in both seasons. Kaolin in mid Dec. gave the highest significant values in fruit length and width of Aggezi and Picual cvs. during the two growing seasons. Although fruit weight (g) of Picual cv. was affected significantly by kaolin on mid Feb. in both seasons, Aggezi cv. Affected by kaolin on mid Jan. and Kaolin in mid Feb in 2011 and 2012 seasons, respectively. As for flesh/fruit weight percentage, kaolin on mid Feb. surpassed other treatments in both cultivars.Calcium carbonate on mid Feb. increased oil percentage on dry weight basis of Aggezi cv. in both seasons, whereas the same treatment affected significantly Picual cv. during the second season only.

Two field experiments were conducted at the exp. Res. Stat. Fac. of Agric., Cairo Univ, Giza, Egypt during 2011and 2012seasons to investigate the effect of seed inculcation with Rizobactrein and/or organic fertilizer(Compost) computed with control treatment under two level of nitrogen fertilizer on growth, yield productivity, Seed quality ,fiber properties and same chemical constituents of cotton. Results showed, that fertilizer treatment under study had a significant effect on all studied traits where as the best treatment was use of Rhizobactrein + Compost and75% N which give the best result in plant height, No. of sympodial branches, No. of open bolls/plant, boll weight, seed index, seed cotton yield per plant and per fedden, lint percentage and Earliness percentage. Oil and protein percentage significantly affected by fertilizer treatment whereas Rhizobactrein + Compost and75% N application give the highest values of oil and protein percentage. Fiber length,fiber strength and micronaire reading didn't significantly differ as affected by fertilizer treatment in both seasons. Use of Rhizobactrein + Compost and 75% N increased chlorophyll a & b and total, total soluble suger, carotenoid and Net income/ fed. From the present study it could be concluded that, use of biofertilizer, Rhizabactrein (200g/30kg seed/fed), and compost with 75% N produce high growth and yield components.

Two field experiments were carried out on rosemary plants (Rosmarinus officinalis L.) at the experimental Baramoon Research Farm, Dakahlya Governorate, Egypt, during two successive seasons, 2010-2011 and 2011-2012, , to study the effect of different sources of organic manure (FYM) mixed of poultry and cattle manures, humic acid, biofertilization nitrogen fixing bacteria (microbein) and phosphate dissolving bacteria (phosphorein), as well as active dry yeast on vegetative growth, herb yield, essential oil production and chemical composition of plants.
The results clear that in both seasons, all fertilizer treatments achieved significantly better growth and yield than the untreated plants (control) which received recommend dose of NPK.. Treatments included that plant biomass responded linearly to (FYM) application and most values of all measurements were realized at the rate of 30 m3/fed. than obtained at both 20, 10 m3/fed. in comparison with those of control plants in both seasons, respectively. Also, it is evident that the application of (FYM) at rates of 10, 20 and 30 m3/fed., interacted with combinations of both (phosphorein + microbein), (phosphorein + yeast) and (phosphorein + humic acid) improved significant increments in the all growth characters compared with control plants, and the highest one was realized with combination of (FYM) at rate of 30 m3/fed. + phosphorein + humic acid.
These findings clearly indicate that phosphorein, humic acid and 30 m3/fed. of (FYM) could be used as traditional fertilizers instead of chemical ones and may consequently minimized pollution of agricultural environments.

Two field trials were carried out through two years, i.e. 2009/2010 and 2010/2011 winter seasons at Shandaweel Agriculture Research Station, Sohag Governorate (Upper Egypt). The aim of this study to investigate intercropping three field crops (wheat, faba bean and onion) in three plant densities as a companion crops with tomato, aiming to protect it from cold and frost, as well as, wind. A split plot design with three replications was used in both seasons. Keeping the three field crops in the main plot and plant densities (one, two and three rows) in the sub plots. The obtained results indicated that the intercropping tomato plants with the mentioned crops resulted in protective producer against the low cold temperature and wind which led to decrease percentage of injured plants and flowers as compared with the solid planting. The yield and yield components of tomato were decreased under intercropping condition. The reduction was estimated 15.5% for fruit set percentage, 25.3% for average fruit weight, 14.5% for number of tomato fruits/plant and 15.8% for yield/fed as compared with solid planting. Intercropping tomato with wheat recorded the lowest values of injured and dead plants percentage. The reduction in yield and yield components was lesser than with onion. The results also show clearly that the high plant density (three rows) had more protective against cold temperature which led to earliness flowering and reduced the percentages of both injured and dead plants as compared with low density. The reduction in yield and yield components of tomato under high density were higher as compared with low density. Intercropped crops (wheat, faba bean and onion) were affected by plant density under intercropping condition. The yield components of the three crops were increased especially under low density (one row) which had wide distance between plants as compared with solid planting. However, the seed and bulb yield/fed were more decreased especially under low density (7.4% for wheat, 57.0% for faba bean and 70.1% for onion). The highest values of land equivalent ratio (1.48), monetary advantage index (12292.2) and net return (32738.0 L.E/fed) were observed when intercropping with onion. In general, under intercropping, the damage of tomato fruits was decreased and marketable yield was increased. These could be attributed to plant height and plant density of intercropped crops. This density must be low (1-2 rows) in tall crops, wheat and faba bean; and the opposite in short crop (onion).

Two field experiments were conducted during 2010/2011 and 2011/2012 winter growing seasons in the Experimental Farm of Faculty of Agriculture, Cairo University at Giza, Egypt. The aim of this investigation was to study the response of two wheat cultivars via, Sakha 69 and Gemmiza 10 to five fertilizer treatments (1) 100% NPK recommended dose, as a contro (2) 50% NPK + microbin, (3) 50% NPK + phosphorin, (4) 50% NPK + potassiomage, (5) 50% NPK + microbin + phosphorin + potassiomage .The recommended quantities of NPK fertilizer (R. Q. F.) which are ( 75 kg N/fed, 100 kg P2O5/fed and 24 kg K2O/fed). Data obtained clearly revealed that:
Varieties and bio chemical fertilizers had a significant effect on most of traits under study where Gemmiza 10 variety was superior in plant height, weight of 1000-grain, No. of tillers/m2, spike length, grains weight/spike, No. of grains/spike in both seasons and No. of spike/m2 and weight of spike (first season). Use of 50 % NKP + microbin + phosphorin + potassiomage was superior in plant height, 1000-grain weight, No. of tillers/m2, spike length, No. of grains/spike, weight of grains/spike, No. of spikes/m2, biological and grain yields /fed in both seasons and harvest index in only the first season.
The interaction between varieties and fertilizer treatments significantly affected most of characters. Gemmiza 10 with 50 % NPK + microbin + phosphorin potassiomage + was superior in plant height, spike length, No. of spikes/m2, No. of grains/spike and No. of tillers/m2. Use of 50 % NPK + potassiomage with Sakha 69 or Gemmaiza 10 gave the highest average of harvest index while use of 100 % NPK with Sakha 69 or Gemmiza 10 gave the highest in straw yield (first season). Use of 50 % NPK + microbin + phosphorin + potassiomage with Gemmiza 10 gave the highest averages of grain yield and biological yield/fed. The shoot and wheat grain contents from mainly N,P and K as well as total sugars, total free amino acids,proteins and total indols were also increased due to this mineral and biofertilization treatments in both wheat cultivars.

Two field experiments were carried out at the Experimental Farm of Sakha Agricultural Research Station, Agricultural Research Center (ARC), Egypt during 2010/2011 and 2011/2012 seasons to study the effect of number of irrigations (one, two and three), planting methods (bed, drilling and broadcasting) and nitrogen levels (67%, 100% and 133% of recommended rate i.e. 75 Kg N/fed) as well as their interaction on yield and its components of wheat Sids 12 cultivar. Each location was performed in separate experiment; every experiment was layout in strip-split plot design with three replications.
The obtained results showed that wheat yield and its components were significantly affected all main factors (number of irrigations, planting methods and nitrogen levels) in both seasons.
The highest values of yield and its components were obtained by applying the treatment of three irrigations after Mohayah irrigation as compared with other irrigation treatments (one or two irrigations) in both seasons.
The highest value of all studied characters were resulted from planting wheat by using broadcasting and bed methods as compared with drilling method in both seasons.
Mineral fertilizing with 100 % of the recommended rate i.e. 75 Kg N/fed gave the highest grain and straw yields and its components of wheat as compared with 67 or 133 % of the recommended rate.
Generally, it can be concluded that planting wheat by using broadcasting method and giving three irrigations after Mohayah irrigation besides fertilizing with 75 kg N/fed in order to maximizing its productivity under the environmental conditions of North and Middle Delta Soils.
