The experiment aimed at studying the influence of different microelements (copper, zinc and mangenese) fertilization technique of soil and foliar application on the production profitability including the cost and yield value in spring triticale cv. Maja cultivated in North-East Poland. With regard to the experiment fertilization techniques, the costs of machines and tractors employment and working capacity and, work and materials were assessed. On the basis of the obtaining effects yield value, immediate surplus, production cost of 1 ton of grain and index of profitability were calculated. The total cost of spring triticale cv. Maja production was from 1203.1 to 1315.2 zł∙ha-1. Generally, the higher cost was with the higher material expenditure and the lower production effectiveness (grain yield) with Florovit foliar fertilization and copper together with zinc and manganese, independently of the application technique. The lover cost of one ton of grain (199.3 zł) and the high production profitability index (215.8%) were obtained with 10 kg∙ha-1 manganese soil fertilization applied together with nitrogen at the dose of 120 kg∙ha-1.
