The report examines the theoretical and practical the scientific achievements in the development and introduction of modern technologies for high maize production for the needs of animal husbandry and industry. identified were problems to be addressed in order to realize maximum productivity in terms of agriculture stable. As a result of targeted research work in recent years the parameters have been optimized of the main technological units according to the sowing terms, agro ecologic region farming and the directions of its use. Identified were the most appropriate predecessors, time and depth for the basic pre-sowing, vegetation and soil tillage. the consumption of fixed amount of nitrogen, phosphorus and potassium contributing the formation of 100 kg of grain has been determined as well as the quantity of leaf-stem mass as a basis for determination of differentiated rates of fertilizing. Inclusive systems have been developed to combat weeds and pests and also the opportunities for the combined application of mechanical and chemical means to combat them. Critical periods are established in terms of factors water and dependence between yield and water.
