Effects of Nitrogen Fertilization Methods on Macro and Micro-Nutrients in Wheat Leaf

Abstract

The aims of this study were to compare the Nitrogen-fertilization methods; Anhydrous ammonia method (M-1), traditional method (M-2), and control method (M-3) and to study the effects on leaf macro-and micro nutrients in the winter wheat plants. The research has been conducted in the ecological conditions of Tekirdag during the 2014-2015 and 2015-2016 growing seasons. The experiment has been arranged in a randomized complete block design with three replications. Leaves collected during three different developmental stages (I-II-III periods) of wheat have been tested for macro and micro-nutrient analysis. Results showed that M-1 method has a positive effect on leaf macro and micro nutrients. The highest leaf N content (3.45%, 3.68%) has been detected in the application of anhydrous ammonia in both year.
