The Influence of Foliar Nutrition of Apple Trees with Silicon on Growth and Yield as Well as Mineral Content in Leaves and Fruits

The technology of producing fruits containing an increased amount elements essential for the health human body, including silicon, has become very important in recent years. Due to popularity apple tree cultivation Europe, appropriate research been undertaken. aim experiment was determine advisability foliar silicon nutrition cultivation. Apple cultivars ‘Gala Schniga’, ‘Ligol’ and ‘Topaz’ were studied treated with three different doses (100, 200, 300 mg SiO2·L−1). treatments performed five times during growth third year from early June late July. Foliar application did not improve evaluated parameters. It significantly influenced, highest analysed concentration, a better fruit yield (12%), higher coefficient, depending on 16 18%, quality (weight size) more extensive red blush. considered differed trees grew strongest yielded best. coefficient found Topaz’ cultivar. had biggest blush Schniga’ sugar content. Macro- micro-nutrient nutritional status no better, except iron copper leaves, at some concentrations applied also zinc fruit.
