Abstract: The analysis of friction head-loss spatial distribution along center pivot lateral lines represents an important step when evaluating energy-use efficiency of center pivot irrigation systems. This work compares head-loss ...

Abstract: Long-term and continuous crop evapotranspiration (ETc) and the crop coefficient (Kc) of jatropha (Jatropha curcas L.), which are needed to determine irrigation requirements, are lacking. The objective of this study was to ...
