Abstract

                                The experiment onpromising wheat varieties was conducted under three levels of irrigation at the Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore for four years (1982-1983 to 1986-1987). Adequate irrigations at six growth stages viz., crown root initiation (CRI), late tillering, late jointing, flowering, milk and dough stages produced maximum grain yield. Among the different varieties HD 2189, DWR 39, NI 8811, HD 4502, NI 5439, HD 2380 and NI 8841, proved better than others under adequate irrigations, whereas, DWR 39, HD 4502 and NI 5439 performed better with two irrigations viz., at CRI and boot stage.
