ABSTRACT
The study was conducted at the Natore City College, Natore, Bangldesh during November 2009 to March 2010 to study different sowing time and irrigation on the growth, development and yield of wheat cultivar, “Shotabdi”. In Bangladesh, the rainfall during the rabi season is characteristically scanty and uncertain. As such wheat gives poor yield under non-irrigated condition. Moreover irrigation facilities are not so extensive to ensure abundant irrigation water through out the country. In sufficient water affects the germination of seed and uptake of nutrient from soil. Nutrients from soil reach the root surface by mass flow and diffusion process which are related to moisture content of the soil. Moreover an irrigation facility is associated with soil water. Six growth phases germination and emergence, tillering, stem elongation, heading, flowering, grain formation and ripening and twelve growth stages germination and emergence, seedling, crown root initiation, tillering, jointing, shooting, booting, heading, flowering, milk, dough and ripe were identified from germination to maturity based on physio-morphological observation. Almost all the growth phases and stages except germination and emergence and seedling stages were influence by sowing time.
Keywords: Emergence, Shooting, Crown root, Initiation, Grain formation and Dough.
