Nitrogen Uptake and Nitrogen Harvest Index in Wheat

Abstract

This research was carried out in the experimental field of The Field Crops Department, Faculty of Agriculture,Ankara University. Four wheat cultivars [two durum wheat Çakmak-79, Kunduru-1149 , and two bread wheat Gerek-79, Gün-91 ] were studied for nitrogen uptake and nitrogen harvest index in two years 1995-1997 . According to results obtained, significant differences among the wheat cultivars in total nitrogen, nitrogen content in grains and nitrogen harvest index occurred in the second year. Significant differences among the wheat cultivars in nitrogen contents and concentrations were also found in chaff rachis plus glumes and awns , leaves and the culm. Nitrogen concentrations in wheat cultivars in the first year were obtained 2.04-2.38 ' /0 in grains 0.34-0.53 % in chaff, 0.76-1.01 % in leaves, and 0.30-0.47 % in the culm; while nitrogen concentrations in the second year were found as 2.29-2.61 %, 0.63-0.75 %, 0.66- 0.84 %, and 0.45-0.68 % in grains, chaff, leaves, and the culm respectively.
