Journal Title: Plant varieties studying and protection - Year 2015, Vol 0, Issue 3
Abstract
Purpose. Determination of optimum dozes of foliar feeding for each cultivar that will provide the highest output of standard rootstocks. Methods. Field, analytical and statistical ones. Results. The author presents the results of study of the hazelnut plant foliar feeding in the mother plantation for vegetative propagation with applying different carbamide concentration combined with 0.1% potassium sulfate (1.50.4 m) in case of horizontal method of growing. Biometric indices of hazelnut layers were analyzed; the influence of each factor on their height and diameter was determined. The rootstocks output per 1 linear meter for each cultivar as well as optimum foliar feeding doze was defined (0.5% carbamide with 0.1% potassium sulfate). Conclusions. The highest output of standard rootstocks in the mother plantation for horizontal vegetative propagation was achieved when applying the foliar feeding with 0.5% carbamide combined with 0.1% potassium sulfate, particularly (thousand rootstocks per 1 ha) for the cultivars: ‘Sviatkovyi’ – 66.7, ‘Dolynskyi’ – 62.1 and ‘Darunok Yunnatam’ – 50.7. For ‘Koronchatyi’ cultivar, the use of 3% carbamide was the most efficient.
