THE EFFECT OF FERTILIZATION ON NODULATION, GRASS YIELDS AND QUALITY CHARACTERISTICS

Abstract

This study was carried out in Harran University in 2017-18 Harran University Faculty of Agriculture in Eyübiye Campus in order to determine the effect of nitrogen fertilization on some nodules, weed yield and quality characteristics of some winter legumes in ecological conditions of Harran plain in Şanlıurfa province. . In the study, the main parcels were leguminous crops (common vetch, Hungarian vetch and fodder peas), while sub-parcels produced nitrogen doses (0, 5, 10, 15 kg/da). According to the findings of the research, the first flowering day number character, at the earliest 103.00 days, with the common vetch 5,10 and 15 kg/da nitrogen dose and 10 and 15 kg/da nitrogen dose of Hungarian vetch, 50 % the number of days of flowering with the earliest 107.00 days. peas 5,10 and 15 kg/da of nitrogen dose, the highest value of the height of the plant height of 15 kg/ha of the feed peas 73.60 cm, the highest number of branches per plant 15 kg/da of the number of branches in the nitrogen dose18.60, the green grass yield character the highest value of 2496.60 kg/da of Hungarian vetch 10 kg/da of nitrogen dose, the highest dry grass yield of 546.40 kg/da with 10 kg/da of Hungarian vetch nitrogen dose, the highest protein in dry grass with 32.62 % of the common vetch 15 kg and nitrogen. In the case of autumn planting in Şanlıurfa and similar ecologies, it can be suggested that Hungarian vetch provides higher green grass and hay yield than feed peas and common vetch and 15 kg/da nitrogen dose of common vetch is considered when considering weed quality
