    Abstract: Plant breeders' ultimate goal in a crop improvement program is to generate varieties with high yield potential in order to sustain high agricultural productivity. In addition to great yield potential, a new cultivar should have stable performance and extensive adaptation over a wide range of settings in addition to great yield potential. The presen...

    Abstract: Soybean is an important crop in hot sub-moist agro-ecological zone of western Ethiopia. However, the yield of the crop is limited due to lack of recommendation on appropriate plant density for the varieties. Therefore, the experiment was conducted to determine the effect of inter and intra row spacing on growth, yield components and yield of soybea... Show More
