Adaptation Evaluation of Released Irrigated Rice (<i>Oryza sativa L.</i>) Varieties in Tendaho Sugar Factory, Afar Regional State of Ethiopia

: Field experiment on adaptation evaluation of five irrigated rice varieties was conducted using Randomized Complete Block Design replicating three times with surface irrigation. This study was executed for the objective of assessing the adaptation capacity of the varieties to isolate the high yielding and heat tolerant varieties in the study area to produce at commercial level for additional income of the factory using freely available resources, like labor and free land not covered by sugarcane. Necessary data were collected at their right stage following their suitable data collection procedures. All collected data were analyzed using SAS software and mean comparisons among treatment means were made by LSD (5%). Significant variation (p<0.05) among the tested varieties were reported owing to their DH, DM, ET, PH, NSLSP, NKPP , GY and TKW characters. However, the varieties didn’t vary significantly (P<0.05) due to their EMD, PL and AGBM traits. Likewise, the yield in the tested varieties shown positively significant correlation (P<0.05) with all yield traits except DH and DM which shown negatively significant correlation (P<0.05). In this trial, highest grain yield of 22.5 Qt/ha was noted from Edget variety. Hibir and Adet varieties also gave statistically similar yield with 19.8 and 19.4 Qt/ha respectively. Therefore, Edget rice variety with highest net profit is recommended for commercial production. However, if any inconvenient condition is faced with this variety, Hibir and Adet varieties can be used as an additional option for commercial production of rice in the study area.
