The increased cultivation of highbush blueberry in Poland has been paralleled with enhanced damage to this crop by different pests and diseases, including soft scales. We have carried out trials to assess methods for controlling soft scales of the genus Parthenolecanium in highbush blueberry grown in open fields or under a plastic tunnel, with an approach based on integrated pest management (IPM)...
Wizualizacja danych jest niezwykle istotnym elementem analizy i prezentacji danych. W naukach rolniczych do wizualizacji danych (w tym danych złożonych) najczęściej stosowane są wykresy kolumnowe, czasami też punktowe i kołowe, rzadko jednak stosowane są bardziej zaawansowane typy wykresów i techniki (jak wykresy trójkątne), oferujące niekiedy bogate możliwości interpretacyjne. W pracy przedstawiono...
Soil and some plant products are still found to be contaminated by DDT residues or metabolites 30 years after its total ban. In order to ensure high quality of organic products and their compliance with the EU rules, following a monitoring carried out to assess DDT and its metabolites residues level in different soils, we started a research program to test some methods of soil remediation, using fungal...
Pests living in the soil cause great damage to horticultural crops every year, particularly those managed by organic farming methods. The most damaging pests are larvae of the genera Melolontha. The purpose of the research was to develop and evaluate the efficacy of a variety of non-chemical methods to reduce the damage caused by the grubs on organic strawberry plantations. The used mechanical methods...
The experiment was carried out in 2007-2009, in the central-eastern Poland. The investigated factors were kind of covers: the control without covering, perforated foil with 100 holes per 1m2 and polypropylene fibre weighing 17·g·m-2, and broad beans cultivars - ‘White Windsor’, ‘Bizon’ and ‘Bachus’. Broad bean seeds were sown at the beginning of the second decade of April, at 50 × 10 cm spacing. Directly...
Badania przeprowadzono w latach 2007–2009. Doświadczenie założono w czterech powtórzeniach w układzie split–plot. Badano wpływ stosowania czarnych ściółek syntetycznych (folia polietylenowa, włóknina polipropylenowa i tkanina polipropylenowa) na plonowanie, długość owoców, grubość perykarpu oraz zawartość wybranych składników odżywczych w owocach dwóch odmian papryki słodkiej: ‘Denis F1’ i ‘King Arthur...
