ASSESSMENT OF YIELD AND QUALITY OF SPRING BARLEY DEPENDING OF FOLIAR FERTILIZATION

Barley is the fourth most important cereal in the world, right behind maize, wheat and rice, but before sorghum, oat and rye. In Republic of Macedonia, barley is sown on a quarter of the entire cereal production area. On the National variety list, there is only one registered variety of spring barley -Makedo. Barley grain yield can vary from year to year. It is highly dependent on of the climate conditions, as well as the agronomic measures applied during the vegetation period. One of the most important measures is the fertilization of the crops. Starting from the fact that the use of chelate fertilizer solutions, using the spray-on foliar method is in the early development phase, an experiment was conducted using spring barley Makedo variety, and three types of chelate fertilizer solutions (Agrosal N12P5K7+МЕ, Agrosal NH4NO3 50% and Agrosal N31P0K0+ME), applied in 6 different concentrations (0.5, 1, 3, 5, 10 and 15 percent).The average grain yield was 1 347 kgha-1, the best results of this trait were registered at the crops treated with Agrosal N12P5K7+МЕ in a 1 percent solution, while the lowest yield was measured on the crops treated with Agrosal N31P0K0+ME in the concentration of 0.5 percent. The quality highly varied depending of the different applied treatments. Highest protein content was registered on the crops treated with Agrosal N31P0K0+ME in a 10 percent solution, whilst the lowest on the crops treated with Agrosal N12P5K7+МЕ, in a 0.5 percent solution.
