The carry-over effects of bioproducts and soil conditioners used in the nursery production on the growth and fruiting of young apple trees of two scab-resistant cultivars ‘Topaz’ and ‘Ariwa’ grown in a commercial orchard were studied. The trees were planted in the spring 2013 and for two consecutive years were not fertilized. In both years a trunk cross-sectional area, the number of shoots and their...
In the years 2005-2013 experiments concerning yielding of potato under organic system in two places of different soil-climatic conditions were conducted. During 9 years in 3-year cycles, 22 cultivars from different group of maturity were tested. It was stated that the yield depended mostly on climatic conditions in years of investigation and cultivars. The place of growing had no statistical influence...
The aim of the study was to evaluate the yielding, yield components and the level of weed infestation of four cereal species which were grown with undersown serradella, or without undersown crop, in organic farms. A field experiment was conducted in the years 2011-2013, in a split-plot design, with four replications. The experiment involved two factors. The first factor included four species of cereals:...
