Abstract:

This study was carried out in the 1860 m scale of Erzurum conditions, with the aim of determining the effectiveness and effects of nitrogen fertilizer applications in different doses on the gene thin (Panicum italicum L.) on some properties. The field test in 2013 and 2014 was established in four repetitive forms according to the success-related full blocks test pattern. The study used 5 different nitrogen doses (0, 3, 6, 9 and 12 kg of N and -1). In the ginseng, plant length, dry substance yield, raw protein ratio and yield, herbal ADF and NDF ratio, biological yield, seed yield and harvest index values are determined. The results obtained from the study can be summarized as below. Nitrogen doses have significantly influenced the performance and other parameters studied except the ADF and NDF rates in the ginseng. The length of the plant, the productivity of the dry substance, the raw protein ratio, the raw protein productivity, the biological productivity, the seed productivity and the harvest index have increased to a certain level with the application of nitrogen. The plant length, dry substance productivity, raw protein productivity and seed productivity have shown significant changes over the years. According to the two-year results, it is recommended to be fertilized in doses of 6 kg N to -1 for the grass production in the Erzurum conditions, and 3 kg N to -1 for the seed production.
