Demonstration and Popularization of Improved Oat Varieties/Accessions at the Highland of Guji Zone High Land, Ethiopia

Tamrat Dinkale


This experiment was conducted with the objectives of to demonstrating and popularizing recommend improved Oat accessions/varieties to the area and to assess farmers preference for the improved Oat cultivars as a feed for livestock production in Guji Zone high land parts. The experiment was laid out in simple plot with size of 10 X10 m under four kebele's of eight farmers two each kebele's of Bore and Ana Sora districts. The materials used for this experiment was CI-8251, CI-8235, 79Ab384 (TX) 80SA95, Lampton, SRCPX80Ab2291and SRCPX80Ab2806 oat accessions. Data was recorded for plant height, maturity date, 50% flowering date, seed yield, diseases reaction, lodging, green fodder yield and farmers preferences. The varieties differed in yield and yield related parameters. Accession CI-8251 produced significantly higher green forage yield (73.13 ton/ha) followed by SRCPX80Ab2806 and 79Ab384 (TX) 80SA95 which was 64.05 and 61.65 ton/ha respectively, the variety lampton recorded lowest green forage yield (55.0 ton/ha) might be due to high lodging and diseases. The highest seed yield (31.34qt/ha) was obtained from SRCPX80Ab2806 accession followed by 79Ab384 (TX) 80SA95 and CI-8235 (31.15qt/ha and 30.65qt/ha) respectively while lampton variety gives only 22.94qt/ha was the lowest yield. The tallest plants (184.5 cm) recorded from Lampton followed by CI-8251 (175.5 cm) and 79Ab384 (TX) 80SA95 (161.25 cm) and minimum (147.75, 154.75cm) from SRCPX80Ab2806 and SRCPX80Ab2291 respectively. Based on their own evaluation criteria, farmers grouped SRCPX80Ab2806 and 79Ab384 (TX) 80SA95 in the first rank; CI-8251 in the second; SRCPX80Ab2291 in the third; CI-8235 and lampton ranked as last. Lampton variety was the most susceptible and have low resistance to disease and no diseases was recorded from accession CI-8251. Low diseases was recorded from 79Ab384 (TX) 80SA95 and SRCPX80Ab 22 91, but resistance to disease and give good yield and yield components. Hence accessions SRCPX80Ab2806, CI-8251 and 79Ab384 (TX) 80SA95 proved its superiority over all the other varieties included in the experiment and could popularized with the same agro-ecology of the zone and other parts of the country.
