The effect of mulching with transparent or black plastic film on soil temperature and some features of the vegetative growth of plants was investigated in the greenhouse production of sweet pepper. Compared with the unmulched control, the temperature of the soil was on average 2°C higher under transparent and black plastic mulch at depths of 5 and 12 cm. The transparent film ensured higher temperatures of the soil during the day, while the loss of heat energy at night was to a greater degree prevented by the black mulch. The vegetative growth of plants measured by their height, number of leaves per plant, and the area and thickness of leaf blades, was distinctly more intensive in mulched stands, slightly better results being noted with the transparent film than with the black one.
