STUDIES REGARDING DYNAMICS OF WATER AND NUTRIENTS ABSORPTION IN WINTER BARLEY AND WHEAT

Experience regarding the dynamics of water and nutrient absorption in plants of barley and winter wheat was made in agriculture year 2012 - 2013, in North Baragan Plain on a typical chernozem soil using different doses of fertilizers. Humidity and nitrogen, phosphorus and potassium elements were determined in different phases of vegetation, in the soil and in plants. We determined dry matter accumulation in plant and plant density also, in order to chase their accumulation dynamics in barley and wheat plants. Based on the results, it could make correlations between soil quality indices and content of macro-elements in plants, in order to apply the correct doses of fertilizer to prevent pollution and achieve higher yields possible.
