Abstract
In the years 2005–2007 field experiments aimed at the evaluation of the effect of a cultivation system on yielding and seed value of five potato cultivars were carried out at the Research and Development Station in Pawłowice. The experimental factors were as follows: 1 — ecological system of cultivation (organic fertilization, mechanical weed control, protection against potato late blight using copper preparations) vs. conventional system of cultivation (organic and mineral fertilization, chemical control of weeds, aphids and potato late blight, 2 — potato cultivars (reproduced from BII in 2005): Felka, Karatop, Asterix, Pirol and Syrena. The experiment was set up in a split-plot design, in three replications. The level of plant infection with virus diseases was low in the first year of seed reproduction (2005), but it significantly increased in the second and third years. Mineral fertilization applied in the conventional cultivation system, particularly nitrogen fertilization, could contribute to the higher rates of plant infection with PVY and PLRV, but the degrees of virus infection mainly depended on genetic resistance of the cultivars. The yield of tubers considerably depended both on the cultivation system and on the cultivar features. Total tuber yield from plots with ecological system was lower by as much as 58.1% than that from plots with conventional cultivation system. The yield of seed potatoes was lower by 43.3%, respectively. Marked differences in yielding between particular cultivars were found. The yields obtained from the ecological cultivation plots, compared to those from the conventional cultivation plots, were characterized by the higher percentage of seed potatoes, lower reproduction coefficient and lower average tuber weight. The above results indicated that for ecological cultivation the most suitable potato cultivars are those showing a high level of resistance to viruses and exhibiting low to moderate fertilization requirements (e.g. Felka and Syrena).
