Cultivation
Citrullus lanatus (Thunb.) Matsum. & Nakai
Growing watermelons in protected ground requires strict vine pruning, artificial pollination, and maintenance of low air humidity, as the crop is sensitive to fungal diseases and light deficiency.
In the reference 112 varieties crop Watermelon, where this is mentioned in the description.
When growing watermelons in protected ground, it is necessary to strictly train plants into one or two stems with pinching of side shoots to prevent overcrowding. Due to the low attractiveness of flowers to insect pollinators in closed structures, artificial pollination or planting of pollinator varieties is mandatory, which is especially critical for triploid seedless hybrids that require a 1:3 planting scheme.
The greenhouse microclimate for this crop should maintain daytime temperatures of about 30°C and nighttime temperatures no lower than 18°C with air humidity not exceeding 60%, as excessive humidity triggers the development of anthracnose, powdery mildew, and olive spot. The high sensitivity of watermelons to light deficiency requires ensuring maximum insolation for proper fruit filling.
