Pre-basic Seed Multiplication and Evaluation of Improved Soybean Varieties on Seed Quality and Seed Yield at Gobu Sayo District of Western Oromia, Ethiopia

One of the most significant sources of vegetable oil in the global economy has been soybeans. An essential component of increasing crop yield and output is seed. Improving seed quality is one of the most cost-effective and efficient inputs for agricultural development because it can significantly boost the crop's potential output. The Bako Agricultural Research Center carried out the seed multiplication during the cropping seasons of 2024, 2025, and 2026. Five Soya bean varieties, Bilo, Gute, Korme, Dhidhesa and kata were multiplied. Seed rate was used 60 kg ha -1 and spacing was used 40 cm between rows. The maximum yield (1766.7kg/ ha), were recorded for Bilo varieties and the minimum yield (1126.6 kg/ ha) was recorded from kata variety. Bilo variety is maximum thousand seed weight because of large seed size when compere to other varieties. The average yield of soybean in the study area was 1401.44 kilo gram per hectare which showed very satisfactory in respect to average yield. Over all, on an average the cost of cultivation per hectare of soybean was found to be a 98700 per hectare. The overall gross return and net return was found to be 208114.94ETBirr and 109414.94ETBirr respectively and the overall Benefit cost ratio was observed 1.108.
