Abstract
The paper presents the results of the research carried out in the years 2004–2007, which aimed to assess the influence of undersown crops on yielding and profitability of table potato cultivation. The following combinations of undersown crops fertilization were applied: control object (without undersown crops fertilization), farmyard manure, birdsfoot trefoil, birdsfoot trefoil + Italian ryegrass, Italian ryegrass. Table potatoes were cultivated in the first year after soil fertilization the table with undersown crops. During harvest the total yield and trade yield were evaluated. Cultivation of table potatoes under conditions of differentiated fertilization has been assesses from the economic point of view. The results obtained indicated that applying of a mixture of birdsfoot trefoil and Italian ryegrass or birdsfoot trefoil alone could substitute for fertilization with farmyard manure in table potato cultivation. Direct production costs for potatoes fertilized with undersown crops were significantly lower than those for potatoes fertilized with farmyard manure. The most profitable was cultivation of potato fertilized with a mixture of birdsfoot trefoil and Italian ryegrass or with birdsfoot trefoil alone.
