| Evaluation the effect of heat stress on winter and summer planting systems on quantitative and qualitative yield of potato cultivars in field conditions Abstract Potato is one of the most important crops in the world which currently is cultivated in many climates of the different parts of the world. In order to evaluate the response of different potato varieties to the planting date in Boshrooyeh area, two independent experiments were carried out using split plot desing in randomized complete block dising in February 2015. The first experiment was conducted using three sowing date, including: February 9, February 24, and March 11, 2016, as main plot and three potato vareties, including: Fontane, Picasso and Sante, as subplot. In the second experiment (summer crop), the same cultivars were cultivated at the sowing dates of August 11, August 27, and September 11, 2016. The results showed that, in both winter and summer planting dates, delaying in planting caused to decrease in tuber yield. In the winter crop, the highest yield was obtained from Sante in sowing date of February 9, and in summer crop, the highest yield was obtained from Fontane and Picasso in sowing date of August 11. The dry matter percentage of the tubers also decreased with delay in planting date, both in winter and summer planting dates.
