Cultivation
Valerianella locusta (L.) Laterr.
Growing corn salad in protected environments requires maintaining a cool temperature regime and intensive ventilation to prevent leaf coarsening and powdery mildew infection.
In the reference 30 varieties crop Corn salad, where this is mentioned in the description.
Corn salad is a cold-hardy crop for which a greenhouse serves not as a heat source, but as protection from precipitation and extreme temperatures. Optimal growth of the leaf rosette is possible at temperatures below +18 °C; exceeding this threshold causes a "greenhouse effect," leading to rapid bolting and loss of marketable quality.
The primary requirement for protected cultivation of this crop is ensuring active air exchange, as stagnant air triggers powdery mildew infections. During the winter period, greenhouses are used to maintain frost-free conditions, allowing for harvests with minimal heating costs, given the plant's high frost resistance.
The specifics of care in protected environments are complicated by the high sensitivity of corn salad to physical impact, which necessitates gentle handling when performing agrotechnical operations in dense plantings.
