ANTIFUNGAL activities of cyanobacterial filtrate, compost tea, H 2 O 2 , garlic oil, barnyardgrass root exudates and Premis fungicide were tested against Cephalosporium maydis, the pathogenic fungus of late wilt disease of maize plants. In vitro and two field trials were carried out during 2015 and 2016 growing seasons under disease nursery conditions. In vitro, cyanobacterial filtrate and 30% premis fungicide were the superior treatments, by them linear growth of C. maydis were prevented totally and fulfillment inhibitions (100 %) were resultedwith lowest IC 50 values. Cyanobacterial filtrate and 3% H 2 O 2 were more effective in developing grain germination. Disease incidence showed better efficacy due to use 30 % Premis fungicide followed by 3 % H 2 O 2 with massive disease reductions reached 83.21 and 75.37 %, respectively during 2015 season. Effectiveness of the 3 % H 2 O 2 dose was extended to the 2016 season with 5.11 % disease incidence and 73.39 % disease reduction. For grain productivity, remarkable enhancements in the weights of both 10 ears and 1000 grains due to all treatments compared to control were recorded in both seasons. Due to their antifungal activities, qualitative analysis of Cyanobacterial filtrate and barnyardgrass root exudates was assayed on Gas chromatography mass-spectrum (GC-MS). Malonic acid, 2,3-Butandiol, Hexestrol, 12-Crown-4-ether and cis-Vaccenic acid were the major compounds extracted from the cultured blue-green algae. Whereas, Nadolol, Quinine, α-Methylionol, Phyllocladene, alcohols, acids, phenols and 2,6-dihydroxy benzoic acid were the most abundant antimicrobial agents in the barnyardgrass root exudates.

The aims of this investigation were (1) to study the influence of mixing various levels of coconut milk to cow milk on the chemical composition, sensory evaluation and rheological properties, (2) to determine the activity of classic yoghurt and ABT cultures in the previously mentioned milk. Acidity, E h , total nitrogen and ash levels of cow milk were slightly higher than those of coconut milk. On the contrary, total solids and fat values highly raised in the coconut milk than in the cow milk. Coconut milk obtained the greatest scores for color, appearance, body and texture; and the lowest scores of flavour. Increasing of acidity and E h values within fermentation was lower in coconut milk than in cow milk. Incorporation of coconut milk with cow milk reduced the development of acidity and E h in mixed milk. Blinding of different levels of coconut milk with cow milk lowered the curd tension values. Syneresis values of cow and coconut milk mixtures were higher than that of cow milk only.

Applicability of salt-tolerant bacterial isolates (F1 and E1) of Rhizobium leguminosarum biovar viciae was compared with the mineral Nitrogen fertilization on faba bean plants, under saline field conditions. Higher magnitudes of shoot length, dry weight of shoots and roots than control and N-fertilized plants were achieved. Results were more pronounced due to use dual combinations of F1 or E1 with 25 % N-supply. Parameters of N2-fixation, seed yield and its crude proteins of both faba bean cultivars (Nubaria 1 and Sakha 1) were also, enhanced due to superiority of the dual treatments. So, utilization of salt-tolerant rhizobial isolates could be attributed to overcome the harmfull effect of soil salinity on growth, nodulation and seed productivity of faba bean plants. On the other hand, the largest diameter of inhibition zone reached 4.20 cm which representing 46.67 % growth inhibition of Rhizobium which was achieved via 1 g L-1 of Vitavax under laboratory conditions. Slope fitting data of the experimental values showed constant inhibitory effect of Ground-up, Malathion and Vydate with increasing their concentrations against Rhizobia. For Vitavax, sharp ascending slope was resulted; indicating induction of further inhibition with additional dose would be expected.
