He said the persistent severe winter weather conditions can create many problems for crop plants jeopardising their health and even their lives. The frost can significantly damage different parts of the plants resulting in low agricultural productivity.
He said normally the off season tunnel crops grown are cucumber, tomatoes, summer squashes, pepper and sweat pepper. Tunnel farming is gaining popularity, and being practiced in many areas of Punjab like, Faisalabad, Mamokanjan, Gujranwala, Okara, Sahiwal.
Experts say that during foggy seasons the plant leaves remain wet for longer period and there are more chances for dissemination of diseases. The optimum temperature range for tunnels production should not be less than 10c in coldest months of December and January.
Dr Ali said mango trees are amongst the most cold sensitive fruit plants . Low temperatures cause far more damage to leaves and twigs of the plant than high temperatures.
However, he said other winter crops including wheat, grams, mustards etc are in good condition so far. Wheat has been over 16.4 million acreage which is 2.6 percent more than previsions year in the province.
