Early sowing of 15th July gave maximum emergence/m2 (12.11), plant height (152 cm), cobs/plant (1.300), grain yield (4419 kg ha1). Delayed sowing of 15th August decreased all the above mentioned parameters. Among the cultivars, Sarhad white had the highest emergence of seedlings/m2 (10.44), days to tasseling (61.00), days to maturity (124.1) grain yield (3354 kg ha1), while cultivar PS EV showed poor performance. Generally cultivar Sarhad White sowing on 15th July produced the best results among all others respectively.]]>Anonymous,19981998Cardoso, M.J. and C.M. Mundstock,1982146973Gill, M.S. and A.
