The aim of the study was to evaluate the effect of HPS and LED assimilation lighting and LED interlighting on the yielding and as cucumber fruit quality in autumn cultivation cycle. The possibilities of increasing the density of plants due to the use of LED technology were also assessed. The study was conducted in three compartments: I with HPS top light only; II with top light HPS + 2 line LED interlight,...
Endive plants were hydroponically grown in greenhouse control conditions. The aim of this investigation was to assess the biological quality of endive cultivated in three different growing media. Organic media: coconut fiber and wood fiber, were compared to rockwool, commonly used as a standard horticultural medium in greenhouse vegetable production. Three crispum leaf endive cultivars: ‘Galanti’,...
Endive is a leaf vegetable, not commonly known in Poland, although popular in Western and Southern Europe. It deserves attention because of its high nutritive value and bitter taste caused by sesquiterpene lactones. In the experiments carried out in the years 2008–2009 the effect of mineral-organic fertilizers (Goëmar Goteo, Aminoplant) on the yield and quality of curly endive (‘Cigal’) and escarole...
The most popular and efficient growing medium in soilless crop are rockwool but researches try to introduce as well other growing media to horticultural practice. Nowadays cherry tomato is a widespread typ grown under greenhouse conditions and grafting can be a resource let to obtain cultivars with a higher fruit yielding. Two tomato cultivars: typical cherry ones as ‘Dasher’ with red skin and ‘Organza‘...
The cucumber crop size depends not only on the cultivar and agrotechnical conditions but also on proper pollination of flowers. The aim of the work was the investigation of the efficiency of bumblebees used in the cultivation of cucumber on the yield, physical parameters and chemical traits of fruits. The investigations were performed on two cucumber cultivars Pavlina F₁ and Natasia F₁ obtained from...
In the intensive tomato production under covers, the soilless cultivation dominates. The objective of this study was to assess some quality traits of cherry tomato and middle fruit size tomato, concerning their chemical composition and sensory attributes as well as their correlation to growing medium and harvest time. Cherry tomato (Dasher F1 and Organza F1) and middle fruit size tomato (Admiro F1...
Four tomato cultivars Macarena F₁, Faustine F₁, Cathy F₁ and Fanny F₁ were used in the study. Transplants were grown in a greenhouse. Seeds were sown at the end of March. The plants were grafted on Maxifort F₁ rootstock on April 5, 6 and 21 in the years 2006, 2007, 2008 without the use of biostimulators. In the case of the other combinations each year the following treatments with biostimulators were...
