| Abstract:
The aim of the investigation was to evaluate the effect of drip irrigation and mulching with black polyethylene plastic on the yield and fruit quality of two tomato cultivars. Irrigation evidently increased total yield by 16 % and marketable yield by about 28 % in comparison to plots without irrigation. Mulching with black plastic also increased total yield by about 20 % and marketable yield by about 24%. Irrigation and mulching did not show any influence on the early yield of tomatoes. In the condition of irrigation and mulching the higher marketable yield was found for cv. Luca in comparison to cv. Radek. The drip irrigation gave an evident increase of fruit weight and fruit compression resistance in comparison to non-irrigated plants. Drip irrigation decreased the amount of carbohydrates, fiber and nitrates in tomato fruits. Mulching with black plastic increased compression resistance of tomato fruits. Irrigated plants of cv. Luca showed a lower content of vitamin C, organic acids, pH value, and worse color in comparison to fruits of cv. Radek. Interaction of irrigation, mulching and cultivar was evidently shown on the content of dietary fiber. Irrigation and mulching decreased content of soluble fiber in tomato fruits of both tested cultivars. | |
