The cost-effectiveness of four production systems of a short-straw form of winter triticale (cv. Alekto) with different levels of nitrogen fertilization and fungicide treatment was determined. Based on the current prices of means of production, the total cost of winter triticale production was estimated at PLN 2200-2600, and direct costs accounted for 60-65% of total costs. Regardless of the applied production technology, the predominant cost items were mineral fertilizers (30-39%), followed by the costs of tractor and machine operation (approximately 26-30%), crop protection agents (approximately 11-19%) and labor (approximately 3%). The highest productivity (grain yield per 1 ha) and cost-effectiveness (income per 1 ha, unit production cost, profitability ratio) were noted in a production system where short-straw winter triticale was fertilized with nitrogen at 120 kg·ha^-1 N in two equal splits (BBCH 27 and 32) and subjected to two fungicide treatments (BBCH 31 and 39).
