Optimum sowing date, seed rate and harvesting stage of barley as a
forage crop in the Gezira
Shadia. A. Salih , Mohammed A. M. Khair and Faisal, M. A. Elhag
Abstract:
An experiment was conducted in the Gezira Research Farm during the
winter seasons of 2001-02, 2002-03, 2003-04 and 2004-05 to determine the
optimum sowing date, seed rate and harvesting time of barley as a forage
crop. The treatments comprised four seed rates viz 48, 96, 144 and 192
kg/ha and five sowing dates viz 1 Nov, 15 Nov, 1 Dec, 15 Dec and 1 Jan.
For the assessment of the quality, the crop (1 Dec sowing) was sampled
fortnightly for the proximate analysis. The results showed that, the
highest dry matter yield (at milk stage) was obtained when the crop was
sown on 1 Dec in 2001-02, 15 Nov and 1 Dec in 2002-03, 1 Dec and 15 Dec
of each of 2003-04 and 2004-05 seasons. In addition, combined analysis
over the four years showed that 1 Dec was the optimum sowing date.
Regarding effects of the seed rate, no significant differences were
observed in 2002-03 season, while 48 kg/ha produced significantly lower
yield than the other three seed rates in the other seasons and in the
combined analysis. Hence, 96 kg/ha could be considered as the best
choice for planting barley as forage in winter. With respect to the
quality, harvesting the crop at the milk stage resulted in the highest
crude protein yield while the other quality attributes were not
drastically affected in comparison to their values at earlier stages.
