Agricultural experts at Punjab Agricultural University (PAU) have advised growers to protect vegetables from frost as temperatures drop.
Satbir Singh Gosal, Vice-Chancellor of PAU, said various biotic and abiotic stresses severely affected vegetable production. In addition to frost, he said, summer vegetables such as cucurbits, chillies, tomatoes, and brinjal were highly affected by it.
Despite being sown in October and November, winter vegetables such as cabbage, cauliflower, onion, and garlic were not greatly affected.
According to Dr Tarsem Singh Dhillon, Head, Department of Vegetable Science, “Plant covers also protect plants from frost damage.”. Plant covers increase long-wave radiation at night and reduce convectional heat loss.
