Abstract

                                The experiment on promising wheat varieties was conducted under three dates of sowing at the Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore on a clay loam soil for five years from 1982-1983 to 1986-1987 under rainfed conditions. The sowing of rainfed wheat during October 8th to 14th proved to be the optimum time of sowing for all the years. Among the varieties HI 617, NI 5439, AKW 65-1 proved better under early sowing (October 8th to 14th). Varieties PBN 22-28, DWR 59 and AKW 65-1 gave more grain yield under normal sowing (October 22nd to 28th). Under later sown conditions, (November 5th to 11th) varieties PBN 22-28, NI 5439, DWR 94 and MACS 1967 were better than others.
