The research was conducted in the years 2007 -2009. The trial was set up as split -plot with four replication. Experience related to the impact of mulching - the use black synthetic mulches (polyethylene film, polypropylene fabric and polypropylene nonwoven) on the yield and fruit biometric features and the content of selected nutrients in the cultivation of two cultivars peppers: 'Denis F1' and 'King Arthur F1'. Seedlings planted permanently in place in mid-June at a spacing of 50 to 50 cm. Harvesting were made gradually as of fruit ripening. Based on the of the obtained results it was found that the yield of peppers depended on the weather conditions and was variated in the years of experience. Higher yields fruits collected from the 'Denis F1' especially grown on leaf litter of black polyethylene film. The longest fruits were collected from plants mulched nonwoven polypropylene. Thicker pericarp had a variety of ‘King Arthur F1' mulching with polyethylene film. Mulching the soil favored the accumulation of L-ascorbic acid, total and reducing sugars in the fruits of peppers.The results showed that all types of mulches have contributed to a reduction in dry matter content in fruits compared to the control ...
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 after sowing the field was covered by covers, which were left on the plants for 3 weeks. After removing the covers the height of plants was measured. Broad bean was harvested at the stage of milk maturity of seeds. The height of broad bean plants and the number of pods per plant were determined prior to the harvest. During the harvest the weight of pods and the yield of fresh seeds were determined and productivity of seeds was calculated from the weight of pods. Biometric parameters of pods and seeds i.e. length of pods, the number of seeds per pod and length, width and thickness of seeds were measured. It was found that the broad bean covering contributed to increase in the height of plant and yield as well as improvement of the ...
