Mineralsare the most important compounds for human nutrition that are sup-plied by vegetables. The content of mineral in vegetables depends on the species and the cultivar, but it is subject to changes under the influence of environmental conditions and agricultural factors. This study examined the effect of sowing date (5, 15 and 25 May) and plant spacing (1 × 0.6 m, 1 × 0.8 m and 1 × 1 m) on selected bionutrient contents (P, K, Ca, Mg and Fe) in the fruits of two spaghetti squash cultivars, ‘Makaronowa Warszawska’ and ‘Pyza’, originating from Poland. A field experiment was carried out in central-eastern Poland on loamy sand soil. Fully-mature spaghetti squash fruits were har-vested from the beginning of September to the beginning of October. The sowing date of the spaghetti squash did not affect the dry matter content, K, Ca or Mg in fruits. The P content was the highest for plants sown on 25 May. In contrast, the highest Fe content was found for plants sown on 5 May. The dry matter content was highest in the fruits of plants sown with 1 × 1 m. The increase in the distance between plants in a row from 0.6 to 0.8 or 1 m resulted in a decrease in Fe content only for plants sown on 15 May. Plant spacing did not have a significant effect on the remaining bionutrient content in the spaghetti squash fruits. The content of dry matter, P, K, Ca, Mg and Fe in the fruits of both cultivars did not differ significantly, although ‘Pyza’ tended to accumulate the most Ca and had lower K and Fe levels.

Potato is an important nutrient source in human nutrition. Potato tuber quality is affected by a cultivar, environmental conditions and agricultural practices. The study examined the effect of dose (0.2 dm3 ha–1 and 0.4 dm3 ha–1) and date of Tytanit® application (a single foliar application at the leaf development stage – BBCH 14–16 or at the tuber formation stage – BBCH 41–43, and a double foliar application at the BBCH 14–16 and BBCH 41–43 stages) on the tuber quality of very early potato cultivars (‘Lord’ and ‘Miłek’). Potatoes were harvested 75 days after planting (the end of June). Tytanit® (8.5 g Ti in 1 dm3) did not affect the content of dry matter, starch, monosaccharides, protein, L-ascorbic acid or nitrates in potato tubers. The very early potato cultivars responded differently to the Tytanit® applied. This growth stimulant caused an increase in total sugars content in the tubers of ‘Miłek’ and had a greater effect on the discoloration of tuber flesh after cooking of this cultivar. The contents of dry matter, starch, total sugars and protein in ‘Miłek’ tubers were higher than in ‘Lord’ tubers, while the content of monosaccharides, L-ascorbic acid and nitrates in tubers of both cultivars did not differ significantly.

The use of synthetic materials for mulching is a very common practice for vegetable crops. Soil mulching influences the microclimate around plants and soil environmental conditions. Mulching with black materials is particularly recommended for thermophilic species, especially those requiring high soil temperature. An experimet was established to evaluate an effect of soil mulching with synthetic materials (black polyethylene film, black polypropylene nonwoven 50 g∙m, black fabric 94 g∙m-2) on the fruit quality and nutritive value of two melon cultivars (‘Seledyn’, ‘Yupi’) cultivated in the field under the climatic conditions of central-eastern Poland. The greatest numbers of fruit per 1 m2 and marketable fruit were harvested in the year 2007 which was most favourable for melon growing compared with the remaining study years. The number of the fruits which were either unripe or showed symptoms of decay did not differ significantly in individual study years. ‘Yupi’ was characterised by a significantly higher total number of fruit and number of marketable fruit than ‘Seledyn’. ‘Yupi’ fruits were less affected by decay than ‘Seledyn’ which, however, produced significant less unripe fruit. ‘Yupi’ fruits had significantly more dry matter, total sugars, monosaccharides and vitamin C as compared to ‘Seledyn’. In both the cultivars examined, higher nutrient contents were determined in the fruit grown using black film mulching.
