Content of mobile forms of micro-elements in soil is a base for the development of the technologies of fertilizer application in definite conditions. Insufficient content of mobile forms of fertilizers in soil often appear a limiting factor for crop yield formation and agricultural production quality. Boron positively influences on photosynthesis, protein and nuclear exchange, crop formation and yield level of the seed; intensifies growth of pollen tubes and increases number of flowers and fruits. Tubercular plants require boron for normal development of tubers. Molybdenum is another element, necessary for normal bio-and photosynthesis, formation of amino acids and proteins. Deficit of molybdenum leads to accumulation of nitrates, declining crop yield and quality of agricultural production. Therefore, creation of new forms of micro-fertilizers with necessary trace elements, such as boron, molybdenum, magnesium and others, appears a serious problem of agriculture. Evaluation of agronomic and economic efficiency of the influence of new forms of micro-fertilizers on crop yield and quality of seeds of pea (Pisum Sativum) is presented. Application of fertilizers with different trace elements (boron, molybdenum, cuprum and others) in their content is analyzed. Economic efficiency of each grade of new micro-fertilizer is evaluated. The following conclusions are made: application of micro-fertilizer Elegum B increases productivity of peas on the background N30P60K90 in average 2009-2010 on 4.7 c/ha; application of Vitamar – on 4.8 c/ha; utilization of Basroliar 36 Extra increases crop yield on 4.7 c/ha and application of Ekolist rises crop yield of grain legumes on 5.3 c/ha.
