ADAPTABILITY STUDY OF OAT (Avena sativa) GENOTYPES FOR THEIR AGRONOMIC PERFORMANCE AND NUTRITIVE ...

Under the Bore Agricultural Research Centre Adola sub-site, a study was done to identify adaptive, high biomass, dry matter, and grain yielder Oat variety/accessions. Jasari, 5453, and 6710 accessions were the three Oat varieties/accessions that were examined. Three replications of a randomised complete block design (RCBD) were used. Days to 50% flowering, days to maturity, logging, and grain output were all substantially different across treatments (P0.05), according to the results. Jasari (62.8 days) was the early flowering variety, and 5453 was the late flowering variety (72.8 days). Jasari (10.8 days) was an early maturing variety, while 5453 was a late maturing variety (114 days). The highest logging was found in 5453 accessions (42.4%), while the lowest was found in the Jasari variety (24.1 percent ). The highest grain yield (49.3 qt/ha) was achieved from 6710 accessions, while the lowest grain yield (33.3 qt/ha) was obtained from the Jasari variety. Plant height and fresh biomass output were not statistically different between treatments (P>0.05), although the treatments had a numerically high yielder value. From 5453 accessions, the tallest plant height was measured (163 cm). The Jasari variety had the shortest plant height (159 cm), while a variety of 5453 had the maximum biomass output of 2.2 t/ha, followed by 2 t/ha 6710 accessions. The Jasari cultivar has the lowest biomass output of 1.8 t/ha. In terms of chemical composition, the 5453 accession had the highest levels of acid detergent fibre (NDF), neutral detergent fibre (NDF), and DM, and the lowest levels of acid detergent lignin (ADL). The 6710 accession had the highest levels of acid detergent lignin (ADL) and total ash (TASH) and the lowest levels of crude protein (CP), dry matter (DM), acid detergent fibre (NDF), and organic matter (OM) content. The Jasari variety had the highest levels of crude protein (CP), organic matter (OM), and acid detergent lignin (ADL) and the lowest levels of acid detergent fibre (NDF) and total ash (TASH) of all the The results show that 5453 accessions of oat were well adapted and productive in terms of plant height, biomass yield, and seed yield, indicating that they may be able to fill the gap in the community's low quality and quantity ruminant feed supply. As a result, it's feasible to conclude that oat types, notably 5453 accessions, were employed as a protein supplement for Guji's midland, which was suffering from poor quality roughage, low protein, and digestible crop leftovers, which were the main animal feed sources, especially in Guji. Good CP and OM 5453 accessions are recommended for further promotion in the East Guji zone's midland based on their adaptability, plant height, biomass yield, and seed yield.
