Abstract:
A field experiment was conducted in Jebel Marra (Sudan) for two seasons,
2001-02 and 2002-03, on farmer’s fields to investigate the effect of
four sowing dates; early July, mid-July, early August and mid-August and
two sites: Trongtonga at 2800 m and Gorlambang at 2300 m above sea level
(a.s.l.) on the growth and yield of wheat. The experiment was carried
out under rainfed conditions using three cultivars; namely, Debeira, El
Nelein and a local cultivar (Donki). The results showed that the early
sowing (July) produced higher grain and biomass yields, higher number of
spikes/ unit area, more spikelets/spike and more seeds/spike compared to
late sowing. Generally, the crop at the higher elevation site had
greater biomass, higher grain yield and yield components. At low
elevation the three cultivars reached anthesis and matured earlier than
at higher elevation. El Nelein was the earliest to reach anthesis and
produced the highest grain and biomass yields. The local cultivar (Donki)
was the latest to flower and gave the lowest yield and yield components.
