The number of tillers per hill was decreased significantly different under moistures stress at various growth stages except at flowering stage (Rahman et al., 2002). The biomass production was effectively reduced due to decease of photosynthesis rate and dry matter accumulation by 31 37% in experiment conducted (Lilley and Fr 1994c). The biomass reduction and furthermore caused to reduce mean of grain yield 21 percent by effect drought stress at vegetative stage (Sarvestani et al., 2008).
