Abstract: Observation of yields of tef tested in national yield trials (NYT) at different sites and at different times have given variable results. It was assumed that differences in the tef yields were 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 with a capacity of 2 kilograms in a randomized complete design in two blocks and grown in a green house where environmental conditions such as humidity, sun¬shine hours, temperature9 were identical for all the treat¬ments. The pots containing the plants were watered as required with distilled water until the plants 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 were 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 adequate quantities of available nitrogen and potassium.
