In this paper, the level of competitiveness and comparative advantages of broiler meat products from Malaysia and selected counties have been analysed. The level of competitive advantage was measured using four different indices: RXA, RTA, ln RXA, and RC for a period from 2009 to 2017. For each index, the existence of a correlation between them has been investigated to ascertain which of the four chicken meat products stand out with a definite competitive advantage. This research establishes the presence of the international trade market share with products from the Malaysian broiler industry. The results found that, in Malaysia, only HS020712 (whole chickens and capons, frozen) showed an increase in competitiveness over the period 2012 to 2017.

Abstract—Water erosion is the most important problems of the soil in the Jabel Nefusa area located in north west of Libya, therefore erosion station had been established in the Faculty of Veterinary and dryfarming research Station, University of the Al-japel Al-gharbi in Zentan. The length of the station is 72.6 feet, 6 feet width and the percentage of it's slope is 3%. The station were established to measure the mount of soil eroded and amount of surface water produced during the seasons 95/96 and 96/97 from each rain storms. The Monitoring shows that there was a difference between the two seasons in the number of rainstorms which made differences in the amount of surface runoff water and the amount of soil eroded between the two seasons. Although the slope is low (3%), the soil texture is sandy and the land ploughed twice during each season surface runoff and soil eroded were occured. The average amount of eroded soil was 3792 grams (gr) per season and the average amount of surface runoff water was 410 litter (L) per season. The amount of surface runoff water would be much greater from Jebel Nefusa upland with steep slopes and collecting of them will save a valuable amount of water which lost as a runoff while this area is in desperate of this water . The regression analysis of variance show strong correlation between rainfall depth and the other two depended variable (the amount of surface runoff water and the amount of eroded soil. It shows also strong correlation between amount of surface runoff water and amount of eroded soil. Key words: Rain, Surface runoff water, Soil, Water erosion, Soil erosion. arabic 13 English 61

Decreased wheat crop yields due to the presence of weeds, insufficiently effective herbicides, and the development of weed resistance to high-efficiency herbicides indicated the need to develop alternative ways to control weeds. Therefore, we sought a possible solution in examining the efficiency of different concentrations (1, 5, 10 and 20%) of aqueous extracts of Ambrosia artemisiifolia and Sorghum halepense in controlling certain weed species for wheat crops: Avena fatua, Bromus rigidus and Convolvulus arvensis. The efficacy of aqueous extracts through the content of total phenols and four polyphenolic acids (chlorogenic, p-coumaric, and sikimic) on the level of shikimic acid concentration in treated weeds was investigated. Statistical analysis of the data showed that the change all tested concentrations of aqueous extracts affect the change in the concentrations of sikimic acid , especially the 20% solution of A. artemisiifolia. Conducted research also showed that method of monitoring the content of shikimic acid is adequate for determining the herbicidal effect of plant aqueous extracts
