Knowledge about the effect of genotypic variation and sowing date on dry
matter accumulation, remobilization and partitioning in winter barley is
important for crop management. Therefore, in field studies, six winter barley
genotypes of various origin and maturity groups were studied across four
sowing dates. In general, grain yield and dry matter content decreased with
delayed sowing, after mid-October, and average grain yield in late October
and November sowing was lower 14.2% and 16.9%, respectively, compared to the
yield in the optimal sowing date. Among the tested genotypes, high grain
yield and dry matter content was obtained from late and medium early barley
genotypes. Delayed sowing dates, on average, reduced dry matter
remobilization and contribution of vegetative dry matter to grain yield. In
years characterized by high spring precipitation, late September and early
October sowing of medium early and late barley genotypes enable increased
accumulation and remobilization of dry matter and obtainment of high grain
yield.
