Effect of synthetic mulches on melon (Cucumis melo L.) yielding

Effect of synthetic mulches on melon (Cucumis melo L.) yielding

A field experiment was carried out in 2006-2008. The study examined the effect of soil mulching with synthetic materials (black polyethylene film, black polypropylene nonwoven 50 g m-2, and black polypropylene fabric 94 g m-2) on the fruit yield and quality of two melon cultivars (‘Seledyn’ and ‘Yupi’) grown in the field under the climatic conditions of central-eastern Poland. Specimens grown without mulching served as the control. The climatic conditions during the study years had a significant influence on the level of total, marketable and early yield of melon. The highest melon yield was obtained in 2007, which was characterised by the most favourable weather conditions for melon cultivation. The comparison of the cultivars showed that ‘Seledyn’ was better adapted to the climatic conditions of Poland. From cultivation, this cultivar achieved significantly higher early and total fruit yield compared with ‘Yupi’. ‘Seledyn’ was also characterised by a higher share of early yield of the total yield, a higher number of fruit in the early yield and a higher mean fruit weight. In turn, ‘Yupi’ produced a significantly higher share of marketable yield of the total yield and a higher number of marketable fruit.

The Effect of Covers Application in the Broad Bean (Vicia faba ssp. Major) Cultivation

Abstract

The experiment was carried out in 2007–2009. The investigated factors were: the kind of covers – without covering (control object), perforated foil with 100 holes per 1m2, polypropylene fibre weighing 17 g m−2 and broad beans cultivars – ‘Windsor Biały’, ‘Bizon’ and ‘Bachus’. Broad bean seeds were sown at the beginning of the second 10-days of April, at a spacing of 50 × 10 cm. Directly after, sowing field was covered by covers, which were left for 3 weeks. Broad bean was harvested in the stage of milky maturity of seeds. Before the harvest, the number of pods per plant was determined. During the harvest, the weight of pods and the yield of fresh seed were determined and productivity of seed from the weight of pods was calculated. Biometric parameters of pods and seeds i.e. length of pods, the number of seeds in the pod and length, width and thickness of seed was performed. It was found that the broad bean covering contributed to increase yield and improvement of the biometric parameters of pods and seeds compared to the control object without covering. The highest yield of pods and seeds produced cv ‘Bizon’. The best yield was obtained from plants covered by polypropylene fibre. The seeds of cultivated 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 seeds parameters.
