Influence of Different Sowing Dates on the Phenology and Accumulated Heat Units in Wheat

S.A. Haider, M.Z. Alam, M.F. Alam and N.K. Paul    

Abstract: A field investigation was carried out to study the influence of sowing dates on phenology and accumulated heat units of four cultivars of bread wheat (Triticum aestivum L.) at different phenological stages over two growing seasons. There were two sowing dates: early and late. The late sown plants had significantly shorter phenological stages and lower growing day degree than the early sown plants in all the four cultivars. Cultivars Akbar was found to be early and C 306 was found to be late maturing. Akbar had the lowest and C 306 had the highest growing degree days during all the phenological stages under each irrigation regimes. Heliothermal units also showed more or less the same trends. The phenothermal indices and heat use efficiency were found to be higher in the early sown plants than the late sown plants.
