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.

Irrigation Performance of Ilgın Plain Irrigation Association

Water, increasing interests day by day for all living creatures, is essential source. Large partion of water supply has been used in agriculture. Irrigation organizations having the rights to comment on irrigation management have very important role to play in agricultural water management. This study focused onassessment of irrigation performance of Ilgin Plain Pump Irrigation Association. The 13 performance indicators were reseched between years of 2007 and 2015. Following results were obtained from the study:annual irrigation water delivery per unit command area as 1727 – 6334 m 3 ha -1 , annual relative water supply as 0.49 – 1.71, cost recovery ratio as 64.19%, Maintenance cost to revenue ratio 14.95 – 74.30%, Revenue collection performance as 83.54 – 146.97%, Total annual gross agricultural production as 1.19-1.596 tonnes, Output per unit irrigated area as 3145.9 – 9713.1 TL ha -1 , Output per unit irrigation supply as 0.9287 – 3.0087 TL m -3 .

Economical Analysis of Sprinkler and Drip Irrigated-Dry Bean Production

The present study was conducted in 2016 to compare sprinkler and drip irrigation methods with regard to economic aspects. Fixed sprinkler irrigation and drip irrigation were applied in dry bean farming. Full irrigation was practiced. Methods were compared with regard to production costs and gross –net incomes. Current findings revealed that there were not significant differences between sprinkler and drip irrigation in dry bean farming with regard to irrigation costs, total production costs and incomes

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.
