Opis:
Melon is a little popular vegetable to grow in Poland, due to high climatic requirements. Ensuring appropriate thermal conditions for plants growth is possible with relatively late planting seedlings. However, late planting does not guarantee high yield of good quality fruit. The factor enabling the earlier planting seedlings and improving the conditions of growth is the use of flat covers. The field experiment was conducted in 2008–2010 in central-eastern Poland. The effect of planting seedlings of melon ‘Malaga F1’ (15 May, 25 May and 4 June) and the length of polypropylene fibre 17 g·m-2 covering (by 4 and 8 weeks from planting, until harvest, control without covering) on the yield and economic efficiency of melon cultivation in the field was investigated. Most preferably the yield level and profitability of melon cultivation were influenced by planting seedlings on the 15 May and covering by 4 weeks. However, earlier planting decreased the share of marketable fruits in the total number of fruits. The highest share in the costs structure of melon cultivation had the costs of human labour.

Opis:
Melon is a species of high nutritional value, valuable medicinal properties as well as taste properties which are increasingly appreciated by consumers. It is sensitive not only to frost but also to temperatures below 10°C, which cause physiological disorders. Adequate thermal conditions for this plant’s growth can be ensured by an appropriately late planting of seedlings. However, a late planting date does not guarantee a high yield of good quality fruit. Earlier planting of seedlings and improved growth conditions can be achieved through the use of flat covers. The effect of different planting dates of seedlings (15th and 25th of May and 4th of June) and the time when polypropylene fiber covers were removed (4 and 8 weeks after the planting of seedlings, before fruit harvest and control without covering) on the yield quality and selected nutritive value components of melon fruits was investigated. The experiment was conducted in 2008-2010, in central-eastern Poland (51°53′N, 22°27′E). Fruits from plants planted on 15th of May were characterized by the highest yield and weight of marketable fruits, the highest content of dry matter and total sugars, as well as the highest flesh thickness, but the lowest flesh firmness. However, the planting date had no influence on the content of monosaccharides, ascorbic acid and iron or on the acidity of melon flesh. Higher yields were obtained from the covered plants, however the duration of covering had no significant effect on the yield. Fruits from plants covered for 8 weeks or until harvest were characterized by thick flesh and higher weight as compared to ones harvested from plants covered for 4 weeks and uncovered. Covering had no influence on the content of investigated components of the nutritive value of melon fruits.

Opis:
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 biometric parameters of pods and seeds compared to the control object without covering. The highest yield of pods and seeds was produced by ‘Bizon’ cv. Plants covered by polypropylene fibre yielded best. The seeds of grown cultivars were characterized by similar parameters. Polypropylene fibre covering favoured formation of pods and seeds in the pods but did not cause changes in the seed parameters.
