Abstract A field experiment was conducted during the 2014-2015 and 2015-2016 agricultural seasons at the Field Crops Research Unit, Research Station of the Faculty of Agriculture, University of Tripoli, with the aim of identify the important selection criteria of yield under rain-fed conditions for a set of genotypes derived from the International Center for Agricultural Research in the Dry Areas (ICARDA). In this experiment, eight genotypes were used and they were compared to the standard durum wheat variety “Karim”. Results showed significant differences in yield (grain weight per square meter) between the two seasons, where the average yield in the first season was 235g per square meter, which is almost double of the yield achieved in the second season, which did not exceed 110g per square meter. In addition, the genotypes differed from each significantly in yield as an average of the two seasons. The only yield component in which the genotypes showed significant interaction wi.
Efficiency of biological and, chemical control of black scurf disease caused by Rhizoctonia solani Kühn and their effects on productivity of potato crop in Libya
Black scurf disease on potatoes Solanum tuberosum L. caused by Rhizoctonia solani Kühn was considered as destructive disease due to its effect on tuber quality by producing dark brown to black coloured hard masses of sclerotia, irregularly shaped and superficial, varying from small, flat, barely detectable blotches to large and raised lumps adhering tightly to the tuber skin. Five field experiments were conducted on Jafara plan research station at Zahra area which is far with 65 km from Tripoli /Libya during spring 2006 up to spring 2008 seasons. The objectives of this research were to control the black scurf disease by using biological products (Biocont-T), prepared suspension of Trichoderma harizianum and selected fungicides Rizolex (Tolclofos-methyl (%50, Rovral (Iprodione 50%), Miltox special (Zineb 37%+Copper 20%), Remalten (Cymoxanil 64%+Mancozeb 8%), Tachigreen (Hymexazol 30%) and their effects on productivity of potato crop through tuber dressing and soil treatment before plan.

Pediatric infant formula (PIF) is the used food to replace the breast milk. PIF is implicated with outbreaks around the world as it is not a sterile product. It is recommended by WHO to prepare the formula at 70°c. In this study, PIF tins were collected from the local market. Microbial flora was counted and identified, ingredients were compared to the Libyan standards and preparation method was assessed whether they fit Libyan codes and FAO/WHO recommendations. Antibiotic sensibility test was applied for all isolates. The ingredients were similar in each level, However, different brands recommended different temperatures to add the powdered formula in. some pathogens were isolated such as Cronobacter sakazakii, Staphylococcus aureus, Staphylococcus epidermidis, E. coli, Enterobacter cloacae, Citrobacter spp. and Klebsiella Spp. which responsible for diseases worldwide. This study, insists that mothers should be informed about the risk could be caused when PIF is un-correctly prepared,.
