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.

“…The highest share of marketable yield in the total yield in these objects was also recorded. The beneficial effect of using black mulches on the yield of vegetable crops has also been confirmed by Braun et al (2019), Bucki et al (2018), Haapala et al (2015), Franczuk et al (2015), Belel (2012), Kosson et al (2012), and Dobrzański and Anyszka (2006).…”

“…Similar results in other crops have also been obtained by some other researchers. Franczuk et al (2015) obtained a significantly lower dry matter content in pepper fruits mulched with black polypropylene and black polyethylene foil as did Adamczewska-Sowińska and Kołota (2010) in eggplant mulched with black polyethylene film. However, many authors consider that mulching the soil with black polypropylene does not affect the dry matter content of some vegetable crops, e.g., peppers (Adamczewska-Sowińska and Kołota 2010), ground cucumbers (Spiżewski et al 2010) eggplants (Adamczewska-Sowińska and Kolota 2010), and carrots (Anyszka and Elkner 2007).…”

“…Some re searchers report no observed effect of mulching with black polyethylene foil and black polypropylene on vitamin C content, in comparison to crops without mulching, in such vegetables as eggplant fruits (Adamczewska-Sowińska and Kolota 2010) or tomato fruits mulched with black polypropylene (Majkowska-Gadomska and Arcichowska 2010). Franczuk et al (2015) indicated the beneficial effect of mulching, especially with black polypropylene on vitamin C content in sweet pepper fruits. Klieber and Franklin (2000), analyzing changes in vitamin C content during Chinese cabbage storage at 5°C, noted a reduction of vitamin C content in the leaves at an average of 13%, while in outer, greener leaves of cabbage the vitamin C content was higher and in the leaves inside the cabbage heads it was lower.…”
