This paper describes approaches to evaluation of production according to production focus. For this purpose, appropriate assembly plants in given soil and climatic conditions, especially from an agronomic point of view and from the point of view of environmental protection are used. The achievable profit in terms of specific production focus differs by up to CZK 1,500 per hectare. The work includes analysis of agricultural land revenues in terms of the focus on the production of cereals, oilseeds and livestock. It analyzes value of returns on agricultural land using BPEJ. Main basis is certified methodology of calculation of the gross annual rent effect, for specific values of inputs of nutrients, plant protection products and technology costs. The model adjusts returns and costs of agricultural crops according to the current price and cost developments. The paper also evaluates the loss of gross annual rent effect due to incorrect sequencing of crops, especially on the basis of reduced revenues. Observed decline in gross annual rent effect due to improper crop rotation sequence may be up to 1900 CZK per hectare. With respect to the protection of the environment functions for nitrogen doses 50, 90, 100, 110 % are evaluated for given soil and climatic conditions. The impact of 50 % dose reduction of nitrogen is in the case of winter wheat on average 600 CZK per hectare. Own choice of production structure affects economic results especially in warmer climatic regions and while intensive production is used.
