Both the total and productive tillers m2 were highest when the crop was sown on 1st November and lowest when sowing was done on 20th December. Heading and maturity were delayed in the plot sown earlier, grain spike1 were highest on 20th November and 1000 grain weight were highest upto the sowing date of 30th November. Seed rates had only significantly affected 1000 grain weight which reduced when the seed rate was increased to 99 kg ha1.]]>Ahmad, N.R. and R. Singh,1958111724Ashraf, M.,19681968Black, A.L. and F.H.
