Comparison of Two Lateral Move Irrigation Machines Commonly Used in Turkey in Respect of Water Uniformity Coefficient

Abstract

Abstract Aims: The purpose of this paper is to define some criteria such as uniformity coefficient, features of machines, which is used commonly in Thrace region for field crops to be used in system design. In this study, the water distribution tests were performed standards and the Christiansen’s uniformity coefficient (CU) was determined in order to control the uniformity of the water distribution throughout the wings. Methods and Results: Within the scope of the test, 6 mm nozzle diameter, 30, 40, and 50 m h-1 operating speed were used. The wind velocity and prevailing direction is the factor that causes negative influence on water application. Therefore, they were taken into consideration the wind velocity from 0.5 m s-1 to 2 m s-1. The performance test was applied on two different types of irrigation movement machines that have different wing lengths, where 11 and 17 collectors were placed on the left and the right side of the wings. The amount of water collected in the collectors was measured and CU was calculated. As a result, water uniformity coefficients values were varied between 74.72-86.50%. Conclusions: It is advantageous that the wing height and length of one of the machines can be adjustable, it is advantageous that the flow and speed control of the other one's can be done with electronic panel. So, these machines should be tested and developed by crop cultivation. Significance and Impact of the Study: The importance of the study is to improve the system performance, to ensure uniform water distribution on the field surface, to improve the water application efficiency and to develop recommendations for machine manufacturers and users in parallel to increase production capacity.
