Boron Content of Cultivated Soils in Central-Southern Anatolia and its Relationship with Soil Properties and Irrigation Water Quality

Boron toxicity may occur in semi-arid regions due to high levels of B in soils, in the ground water, in fertilisers or in irrigation water (U.S. Salinity Lab. Staff, 1954; Nable et al., 1997).

Analysis of Energy Use and Input Costs for Irrigation in Field Crop Production: A Case Study for the Konya Plain of Turkey

The objective of this study was to determine the energy use and input costs for irrigation in field crop production of winter wheat, maize, sugar beet, dry bean, potato, and carrot. For this purpose, irrigation data for the production of six field crops were collected through a survey of 72 farms. According to the results, the carrot crop used the highest amount of energy for irrigation with a value of 47,655 MJ/ha, and winter wheat used the least at 13,167 MJ/ha. Energy efficiency of irrigation for carrot, sugar beet, dry bean, potato, maize, and winter wheat were estimated to be 3.19, 6.04, 1.11, 2.69, 6.41, and 3.95, respectively. The most important cost item for irrigation was the diesel energy cost. The farms that used electricity for irrigation were more successful in terms of economic performance. It was concluded that excess water and energy use for the irrigation process should be reduced to increase the efficiency of energy use for the production of field crops in arid and semi-arid areas.

Research on Drip Irrigation System Performance under Greenhouse Conditions

This study was conducted to evaluate trickle irrigation system performance under greenhouse conditions in Antalya Province of Turkey. For this purpose, uniformity coefficient (UC) by graphical method as well as emission uniformity (EU) was researched. The UC varied from 56% (unacceptable) to 90 % (perfect) and EU varied from 41% (poor) or (unacceptable) to 92% (perfect or good). The main problems detected were poor system design and clogging within systems. This fact is produced by different reasons, standing out the low efficiency distribution networks, insufficiency in maintenance and repair works and friction losses.
