Abstract
Observation of yields of tef tested in national yield
trials (NYT) at different sites and at different times have
given variable results. It ~/aS assumed that differences in
the tef yields ~Iere probably due to environmental factors.
Therefore, eleven cultivars (of 1980-81 in the NYT)
were seeded on six different soils, collected from different
places, in plastic pots ",ith a capacity of 2 kilograms in a
randomized complete design in two blocks and qrown in a areen
house where environmental conditions such as humidity, sunshine
hours, temperature, were identical for all the treatments.
The pots containing the plants were watered as
required with distilled water until the olants achieved
physiological maturity.
During the growth period, various parameters such as
height, tiller number, days to heading were recorded and
quantified. After harvest dry weight and seed weight of
cultivars \~ere measured. The data obtained were subjected
to various statistical analyses.
The results indicated that. the tested tef cultivars
adapted better in soils dominated by silt along with aC'equate
quantities of available nitrogen and potassium.
