The Effect Of Mash Enzymation On Juice Yield And Chemical Compositionof Sour Cherry Juice, Feryal Karadeni̇z, Azi̇z Ekşi̇
Turkish Journal of Agriculture and Forestry
The effect of mash enzymation on juice yield and chemical composition of sourcherry juice was investigated. The increase in juice yield due to mash enzymation was found between 6.25 and 9.0%, in sourcherry juice prepared from Kütahya variety. PH value, titratable acidity, formol number, anthocyanin, total phenolic, glucose, fructose, sucrose, citric acid, malic acid and mineral contents were also determined in sourcherry juices. According to the results, mash enzymation did not show significant effect on the chemical composition of sourcherry juice.

A State-Dependent Model Of Forest Floor Development, Ertuğrul Bi̇lgi̇li̇
A State-Dependent Model Of Forest Floor Development, Ertuğrul Bi̇lgi̇li̇
Turkish Journal of Agriculture and Forestry
A state-dependent, dynamic forest floor development model is presented. The model considers litterfall as input. The decomposition of the litter was modelled as influenced by the quality of litter and miccroclimatic conditions (temperature and moisture). Microclimatic conditions were determined based on weather data and stand structure. The predictions of the model compared with an independent data set suggested that the model functions realistically under a range of weather and stand conditions. The resulting model should be valuable in the prediction of fire behavior.

Issues Related To Marketing And Extension For Sustainable Agricultural Production In Turkey, Sedef Akgüngör, Taner Kumuk
Turkish Journal of Agriculture and Forestry
Sustainable agriculture, although a difficult term to define operationally, includes the practice of low input agricultural production technologies. An important condition to adopt these technologies is the access to markets for low input agricultural products. Ability to market these products at profitable prices would provide incentives for farmers to adopt the necessary methods. Contract farming is considered to be an effective means to introduce new production technologies to the farmers by providing assurance on prices and markets for agricultural products. Public extension agencies in developing countries may therefore be concerned to direct their efforts to introduce contract farming models to …
