Climate change affects the species composition of agricultural crops. As a result, crops that were not previously cultivated, such as broccoli, tomatoes, and others, are now being grown in fields. The research was carried out on the farmlands of the Gugark community in Lori Province and Archis village in the Noyemberyan Region of Tavush Province. At the beginning of the growing season, seeds of five crop species were sown: cucumber (Cucumis sativus L.), tomato (Lycopersicon esculentum Mill.), potato (Solanum tuberosum L.), bean (Phaseolus L.), and maize (Zea mays L.). The height of seedlings grown from the seeds was measured over a one-month period of growth and development. The height of potato plants grown in Lori Province was 1.18 times higher than those grown in Tavush Province, for tomatoes it was 1.4 times higher, and for maize – 1.3 times higher. The heights of cucumber and bean plants were the same in both provinces. In Tavush, crop sowing is organized earlier, and for some crops, a second sowing can even be done, unlike in Lori Province. The results of the study will make it possible to properly plan crop sowing in both regions to avoid spring frosts, enable second sowing of crops, and achieve higher yields.
