responsibility to assess the quality of each wheat genotype from grinding up to the end of the
baking process. Subsequently, the FRG met as a group to assess the palatability of each product.
Numeric scores were used to record the qualitative data arising from the FRG assessments.
The agronomic data were analyzed separately for each site, and were also subjected to a
combined analysis of variance across the four sites.
Economic analysis of the crop management packages was conducted in accordance with
CIMMYT's partial budget methodology (CIMMYT, 1988). Nutrient prices used were 2.53 and
2.19 Ethiopian Birr (EB)/kg of DAP and urea, respectively. Daily wages were set at 3.50
EB/work-day. Grain was valued at 1.67 EB/kg for threshing and 1.72 EB/kg for planting.
Labor estimates for the various operations were 0.4 work-days/ha for fertilizer application,
7.0 work-days/ha for herbicide application, 13 work-days/ha for hand weeding, and 20.0
work-days/ha for harvesting.
RESULTS AND DISCUSSION
Agronomic Analysis
Grain yield data obtained by the four individual FRGs are presented in Table 1. The grand
mean grain yield across the four FRGs was 1975 kg/ha, while individual site means ranged
from 1614 to 2434 kg/ha. At each site, the highest grain yield was obtained from the
researcher-managed plots since the farmer-managed plots received a lower level of urea
fertilizer and sub-optimal weed control. However, the Ata Seifatra FRG practiced more
thorough hand weeding relative to the other FRGs; as a consequence, the grain yields
obtained under both FM and RM were quite high and similar at this location. The lowest
grain yields were obtained at the Aba Aregay site due to unreliable rainfall during the 1999
growmg season.
The analysis of variance (ANOYA) of grain yields at individual sites (Table 2) indicated an
absence of significant d~fferences among the five genotypes tested, except at the Aba Aregay
site (P
