Abstract
The purpose of the study was to determine the effects of distances between rows (62.5, 75 and 91 cm) and planting densities in a row (30 and 40 cm) on plant growth and development, viral and fungal infections and also the yields of two potato cultivars (Arkadia and Orlik), exhibiting different levels of resistance to diseases and different lengths of the growing season. The plant potatoes of the two cultivars under investigation were reproduced from the elite in 1999 until class A in 2001. The observations of growth, development and occurrence of viral and fungal diseases were carried out during the growing season. Potatoes were harvested at the stage of physiological maturity. After harvesting, the yield and its structure were determined. The results were analyzed statistically using the method of the analysis of variance. The significance of the impact of the factors under investigation were analyzed using an F test in the analysis of variance. The weather conditions in the years under investigation were different; the most favourable for plant development and yielding were those in 2001, while less favourable were the weather conditions in 1999 and 2000. Viral infections increased in subsequent years of reproduction; more infections were observed in the Orlik cultivar with narrow distances between the rows. The occurrence of potato blight was weather-dependent. The yields of potato tubers were higher with Arkadia cultivar and in 2001, but decreased with the increasing distances between the rows, due to a lower number of plants per ha. Higher planting density resulted in increased rates of planting potatoes, but lower rates of commercial potato tubers in the total yield.
