Problem Identification And Priority Setting In Agricultural Research: The Case Of The Eastern Margin Of Central Anatolia, Vedat Uzunlu, Ahmet Bayaner, Surendra P. S. Beniwal
Turkish Journal of Agriculture and Forestry
Since the resources available to research institutes are scarce, and experimentation is the most costly phase of a research program, researchers must make sure that the possible solutions to identified problems have a high chance of success. Consequently, problems should be carefully prioritized for experimentation. Factors limiting increased productivity in crop production in the Eastern Margin of Central Anatolia (EMCA) along with agro-ecological factors, apart from political concern, are agronomic constraints. Limiting factors in livestock production are insufficient feed supply, poor conditions of natural grazing areas, and housing of animals. Increasing the adoption rate of the recommended production practices among …

Turkish Journal of Agriculture and Forestry
Palm kernel oil was hydrogenated discontinuously for a period of 100 min at 165°C and 2,5 atm in the presence of nickel catalyst (%0,18). The changes in iodine number, fatty acid composition, trans fatty acid content and solid fat content during the hydrogenation were investigated for samples taken at 10 min intervals. According to the findings, while iodine number was gradually decreased during the reaction, trans fatty acid content increased significantly. Reaction conditions had increased effect on stearic acid formation from monoens. Trans fatty acid and total saturated fatty acid amounts increased proportionally with increase in SFC values.

Investigation Of Optimum Tillage Depth For Sunflower In Crop Rotation Under Central Anatolian Conditions, Yaşar Murat Çeli̇k, İlhami̇ Ünver
Turkish Journal of Agriculture and Forestry
Optimum tillage depth for sunflower after wheat was studied on Brown soils at two locations in Central Anatolia. The experiments were constituted as split randomized blocks with three replications, the treatments were 9-11, 14-16, 19-21 and 24-26 cm tillage depths. Weeds were permitted for growing in the half of every plot in order to test their adverse effect on sunflower yield. Optimum tillage depth under the research conditions was 14-16 cm from the points of economy and yield. Weed infestation significantly decreased the sunflower yield.

The Acidity Of Important Beech And Oak Species, Mualla Balaban, Güneş Uçar, Ethem Uğur
Turkish Journal of Agriculture and Forestry
The corrosion of metals in contact with wood, discoloration of wood itself, undesirable effects on wood preservatives and the curing of the synthetic resins especially glues in fiberboards, particleboards and some other effects could be traced back to the acidity of wood. Thus, this phenomenon is of a great importance in the wood utilization. In this study, two important industrial wood species , Quercus frainetto and Fagus sylvatica grown in Belgrad Forest in Turkey were investigated with respect to free, bound and total acidity of wood. Cold and hot water extracts were taken to determine the free and bound acidity …
