Abstract
Nitrogen fertilisation is one of the most effective yield-increasing factors but also one of the most critical items of cereal production costs. The aim of the present study was an attempt at defining the optimum nitrogen fertilisation rate for winter barley, factoring in the production, economic and energy effectiveness. The highest yield, profit and profitability ratio was obtained at the nitrogen rate of 90 kg N·ha-1, while the most favourable value of energy effectiveness – at 60 kg N·ha-1.
