Abstract
Drought stress accelerated growth by 3-5 days and decreased by 0.53-0.12 t/ha, relative to control conditions. As for a varieties early maturing varieties have low resistant to drought and low yield potential under favorable moisture condition than medium and late maturing varieties. The early maturing variety Halkhgol 1, medium maturing varieties Darkhan 72, Darkhan 74, late maturing variety Darkhan 144 have superior resistant to drought.
