ABSTRACT: Field experiment was carried out during autumn season of 2012 at the experimental farm, Crop Research Station, beyond to Research Office of Agricultural, Abu-Ghraib/ Baghdad - Iraq. The layout of the experiment was split plot in Randomize Complete Blok Design with three replications. The objective was to study the effect of irrigation intervals and organic fertilizer levels on some growth characteristics, yield and water use efficiency of maize (synthetic cultivar 5018).The irrigation intervals (irrigation every 4 days, 7 days and 10 days) were in main plots while organic fertilizer Top10 levels (0, 3 g L-1 and 5 g L-1) foliar application after 40 and 60 days from planting were in sub plots.

ABSTRACT: This study was conducted in the plant protection department / College of Agriculture / University of Baghdad to evaluate the efficiency of physical agents (ozone, ultraviolet radiation , and microwave oven) on inhibiting Aspergillus flavus growth and destroying the mycotoxin that produced in corn seeds . An isolate af A.flavus producing Aflatoxin B1 was obtained from plant protection deptment college of Agriculture University of Baghdad .the results showed that hight significant reduction in A. flavus growth between treated and non-treated cultures for all the agents used was observed .

ABSTRACT: To estimate the fermentation quality in various treatment combinations after ensiling and to assess feasibility of preparation of silage from hybrid napier. Hybrid Napier (Jaywant), Maize (African Tall) and Lucerne (RL-88) were grown in forage production farm of Research Cum Development Project, MPKV, Rahuri. Hybrid napier grass and lucerne were harvested as first cut at 60 and 40 days after sowing, respectively while maize was harvested at 50% flowering stage.

ABSTRACT: Density is one of the crucial factors for White leg shrimp Littopenaeus vannamei in determining the survival and growth. Five ponds were selected with 0.5hac each in low saline water. They were stocked with 20,30,40,50 and 60pcs/m². The survival (%) and AVG was observed as 84.5; 83.5; 82.5; 79.5; 69.12 and 28.42g, 27.52g, 26.4g, 25.2g and 19.5g in ponds P1, P2, P3, P4 and P5, respectively. Fortnight sampling was taken at 7am.

Key words: L.vannamei, pH, salinity, temperature, density, survival and growth .
