High costs of manual pruning and lack of skilled workers incline fruit growers to mechanical pruning. Mechanical pruning gives good results in the case of trees that do not require selective pruning, like citrus trees. This pruning method is also acceptable if the fruit is produced for industrial purposes. Twelve-year-old ‘Pinova’ apple trees grafted on dwarf M.9 rootstocks, spaced at 4 × 1.5 m, trained...
Hail nets are necessary protection in some fruit growing regions. Several trials showed that the net color may influence tree growth and fruiting. The influence of hail nets on orchard light microclimate, growth, flowering and fruiting of apple trees was examined in field experiment in the years 2004–2010. ‘Šampion’ and ‘Rubinstar’ apple trees grafted on M.9, were planted in spring 2004. After planting,...
Drought is one of the most common limiting environmental factors affecting plant growth and productivity. Strawberry is a plant of large demand for water along with a high susceptibility to drought. In the present study, the response of three strawberry cul-tivars (‘Elsanta’, ‘Honeoye’, ‘Grandarosa’) grown under greenhouse conditions to water deficiency was examined by evaluating the yield and morphological...
Strawberry is propagated vegetatively. Nowadays, traditional bare-root transplants are often replaced with plantlets (plug plants) produced from runner tips. The nutrient level and type of growing medium may influence the quality of planting material. Phosphorus and potassium are important elements for plant metabolism. Insufficient supply of plants with these elements negatively influences the rooting...
Celem badań była ocena wpływu sposobu nawożenia na zawartość azotu w liściach jabłoni. Doświadczenie prowadzono w latach 1993-1999 w SZD w Dąbrowice. Jednoroczne okulanty jabłoni odmian Jonagold i Gala szczepione na podkładce M9 posadzono wiosną 1993 r. w rozstawie 3,5×1,25 m, (2286 drzew na ha). W doświadczeniu zastosowano dwa sposoby nawożenia: posypowy oraz fertygację przy użyciu dwu rodzajów nawozów:...
