Root Yield and Quality of Sugar Beet Under Drip and Sprinkler Irrigation with Foliar Application of Micronutrients
Journal Title: ÇOMÜ Ziraat Fakültesi Dergisi - Year 2018, Vol 6, Issue 1
Abstract
This field study was conducted to determine the effects of different irrigation methods on the yield and quality of sugar beet (Beta vulgaris L. cv.esperanza) in Altıntas-Kutahya, Turkey during 2016 growing season. The experimental design was randomized complete block design with three replications. In two irrigation methods; sprinkler and drip irrigation, full water requirement of sugar beet was meet throughout the whole growing season. In sub-plots, irrigation programs were applied together with foliar application with a mixture of humic acid (humic and fulvic acid 15%, water soluble K2O(0.03%) 2 L ha-1, 20-20-20+TE 2.5 L ha-1 and micronutrients (0.8%B, 1.5%Cu, %5 Fe, %3 Mn, 0.2% Mo, 4% Zn) 0.5 kg ha-1. The irrigation methods has significant effects on root and sugar yield. In drip irrigation system, the amount of irrigation water and evapotranspiration were almost 11% lower than the sprinkler irrigation. Water use efficiency in drip irrigation method increased up to 15.2 kg m-3 by saving water in the root zone of sugar beet. Results also indicated that drip irrigation with foliar application of micronutrients had a significant effect on the root and sugar yield. Generally, it could be recommended that drip irrigation was an effective method in sugar beet production for more root and sugar yield and also saving water. The results presented have important implications for maintaining plant quality and yield, and show the need to adjust the irrigation schedule to avoid yield loss.
