Abstract:
This trial consisted of/mainly, the better varieties tested by the Debre
Zeit experiment station for several years. The differences between the
varieties are not very striking (Table 2). This is thought to be due to
lack of fertilizers (the top-dressing with phosphate did not give good
results). Varieties such as 8156, Penjamo 62, ana Sonora 63 which give
high yields on fertilized soil, uia not perform better than Kentana
?rontana X Mayo 48 when tested on poor soil. This emphasizes the need for
fertilizing experimental plots inorder to reveal the real potential of
outstanding varieties.
There was no significant difference in the yields of the first 6 varieties.
Prom this trial and previous observations. Catcher, Fanfare, No. 43?
Setakuri, and Prins do not appear to be promising varieties for the
Kulumsa area. Although Salmayo has done well in previous trials, it was
found to be very easily damaged by dry wind.
