Abstract
A field experiment was conducted on the pattern of dry matter accumulation in wheat genotypes as influenced by sowing dates during rabi 2000-2001 at Agriculture College Farm, Raichur. The results showed that at harvest, significantly higher dry matter accumulation (337 g m-1 row length) was recorded with wheat sown during first fortnight of November and it decreased in order with each delay in sowing viz., second fortnight of November (306.71 g m-1 row length), first fortnight of December (232.39 g m-1 row length) and second fortnight of December (179.80 g m-1 row length). Significantly higher dry matter accumulation in leaves (97.97 g m-1 row length), stems (80.78 g m-1 row length) and ear heads (158.57 g m-1 row length) were recorded with early sowing (First fortnight of November) when compared to rest of the dates of sowing at harvest. Among the genotypes, DWR-195 accumulated signfficantly higher dry matter in leaves (80.92 g m-1 row length), stems (74.77 g m-1 row length) and ear heads (132.90 g m-1 row length) when compared to rest of the genotypes.
