Watering systems and water use in ornamental nurseries in Poland according to survey investigations

Ornamental nursery in Poland has been developing vary well in the resent years. It is the most success sector within floriculture or even in horticulture at all. Area of production grew up to 6747 ha and the value of production in 2011 was animated on 1 billion PLN. Irrigation is one of the most important factors with great importance on production. Therefore it is important to optimize the ways of using water resources in the process of nursery development. It should be related to not only modern and economical irrigation systems but also with the introduction of rational criteria of irrigation plants grown in the field and containers. Optimizing of watering plants in nursery, using the systems that save water and money should be more important since then. The aim of the study based on questionnaire and authors on visits in the nurseries was to estimate watering systems in nurseries, source of water and amount of water used for irrigation according to holding size, localization and association in producers organizations. In the study 612 holdings were examined mostly by the e-mail survey, but some of them also by authors own visits what was very valuable for this research. Area of ...

INFLUENCE OF GEOCOMPOSITE APPLICATION ON SELECTED BIOMETRIC FEATURES OF ROSA 'WHITE MEIDILAND' AND BERBERIS THUNBERGII 'GREEN CARPET' IN THE CONTAINER NURSERY PRODUCTION

An innovative technology of superabsorbent application in a form of agrotextile filled with polymer, called geocomposite, is a solution that allows preserving the beneficial effect of using superabsorbents with simultaneous reduction of their negative influence on soil environment. Research was carried out in 2012-2014 on one year old cuttings of Rosa 'White Meidiland' and Berberis thunbergii 'Green Carpet' in unheated foil tunnel at the Research Station belonging to the Department of Horticulture at Wrocław University of Environmental and Life Sciences. First factor was the use of geocomposite, while the second was fertilization with full (3 g) and half (1.5 g) dose of Osmocote Plus 3-4M and 3 g of YaraMila Complex fertilizer. The aim of this study was to assess the influence of geocomposite application with the use of fertilizers on selected biometric features and fresh weight of plants. Geocomposite had the positive influence on tested shoots and roots biometric features of Rosa ‘White Meidiland' and Berberis thunbergii 'Green Carpet', on the fresh weight of roots and total of both species, as well as on their root:shoot ratio. In both species there was a tendency to obtain the highest values with 1.5 g Osmocote fertilization. ...
