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 ...
A field experiment was carried out from 2007-2009 at the University of Natural Sciences and Humanities greenhouse complex in Siedlce. The trial was set up as randomized blocks with three replications. In the experiment was investigated the effect of method of AgroHydroGel application (control, AgroHydroGel applied under seedlings, AgroHydroGel applied under plants in the field, half of the AgroHydroGel rate applied under seedlings, the other half under plants in the field) and cultivar (‘Gabi', ‘Delikates Biała', ‘Wiedeńska Biała') on the yield level and quality of kohlrabi grown in the field under the weather conditions of central-eastern Poland. Kohlrabi seedlings were grown in a non-heated greenhouse. The seeds each cultivars were sown in late March to seedling containers with peat substrate amended with AgroHydroGel or peat substrate only. The kohlrabi was harvested two times at 7-10 days intervals, at a minimum bulb diameter of 3 cm. The beginning of harvest was after 50-51 days from the planting of seedlings. There was found that weather conditions in the study years had significant influence on the yield level, average weight and bulb diameter as well as on the nutrient contents in the kohlrabi bulb. The most favourable on the increase of yield of ...
The experiment carried out over 2010-2012 at the experimental field of Crimean Agrotechnological University in Simferopol, Ukraine (44°56'N, 34°06'E). It was investigated the effect of cultivation method (cultivation from seedlings and direct sowing to the ground) and the date of seeds sowing - direct to the ground (first 10-days of March, second 10-days of March, first 10-days of April) - for seedlings (second 10-days of February, first 10-days of March, second 10-days of March); distance between the plants in rows (20, 25 and 30 cm) on the morphological features and yield of leek ‘Sizokrył'. Leeks were grown in double rows spaced by 40 cm. Plants grown from seedlings were characterized by the better biometrics features than grown from seed sowing directly into the ground. Delaying the sowing date of seeds by 10 days at seedlings production (compared to control date i.e. first 10-days of March) influenced the most favourable on the biometrics features of the yield. In the leek cultivation from direct sowing to the ground the earliest date caused achieve the plants with the best parameters. Leeks cultivation in the distance of 25 cm in rows contributed to achieve plants with significantly the highest stalk diameter and the highest ...
