Distribution of tractor available workdays over the southeastern Anatolia project (GAP) area

摘要

Determination of available workdays of a tractor for field operations is very significant in design, development, and selection of efficient machinery systems for agricultural operations. Available workdays vary and generally based on average daily temperature and amount of precipitation. In this study, an excel program was developed to determine the available workdays of a tractor in field operations. Available workdays of a tractor over the Southeastern Anatolia Project (Turkish:?Güneydo?u Anadolu Projesi, GAP) region, opened for irrigation in 1995, were calculated with this software by using the meteorological data of the region. Results indicated significant changes in available workdays from east-to-west and north-to-south. Considering the 15 days period, maximum number of work days corresponds only 33% of the total period in April.
