Abstract


An experiment was conducted in the Gezira Research Farm during the winter seasons of 2001/02 and 2002/03 to study the effect of seed rate and sowing date on growth, development, plant population and forage dry matter of barley.  Four seed rates, viz, 48, 96, 144 and 192 kg/ha and five sowing dates, viz, 1st  Nov., 15th  Nov., 1st  Dec. and 15th  Dec. in 2001 and 2002 and 1st  Jan. in 2002 and 2003 were studied .The results showed that, on average, the highest dry matter of fodder yield (at milk stage) was obtained when the crop was sown on 1st  Dec. in 2001and 15th Nov. and 1st  Dec. in 2002. No significant differences were obtained between the seed rates in 2002/03 season. In 2001/02 season, however, 96, 144 and 192 kg/ha invariably outyielded 48 kg/ha. Hence, the third week of Nov. could be considered as the optimum sowing date, and 96 kg/ha could be considered as the best seed rate  for planting barley as forage  in winter.
