Heat stress due to high temperature is a serious threat to crop production worldwide. This investigation determined field performance of six cultivars from Egyptian clover, i.e., Helaly, Serw 1, Gemmiza 1, Giza 6, Sakha 4 and Fahl under Shandwel Agricultural Research Station Farm, Egypt at high temperature. The results showed that Giza 6 performed the best with total fresh yield (78.35 t ha-1) followed by Sakha 4 (74.7 t ha-1). In dry matter yield the cultivars Giza 6 (multi cut) and Helaly (multi cut) had highest values 11.28 and 11.57 t ha-1, respectively and significant differences among cultivars were recorded. The values of crude protein and crude fiber and ash content per cent differed in different cuts. Fahl cultivar showed no major effect of air and soil temperature and humidity.
