Rice production in Ghana has become unsustainable due to the extremely nutrient-poor soils. It is caused by inadequate soil fertility management, including the inefficient application of fertilizers. A practical solution could be the biofertilizers, sp. B510. We performed field trials in Ghana and Japan to compare the effects of B510 colonization on selected Ghanaian rice varieties grown. The B510 inoculation significantly enhanced the rice cultivars' growth and yield. The phenotypic characteristics observed in rice varieties Exbaika, Ex-Boako, AgraRice, and Amankwatia were mainly short length and high tillering capacity. These features are attributed to the host plant ( Nipponbare), from which the strain B510 was isolated. Furthermore, species has been identified as the dominant colonizing bacterium of rice rhizosphere across a diverse range of agroecologies in all major rice-growing regions in Ghana. Our results suggest that the utilization of B510 as a bio-fertilizer presents a promising way to improve rice growth, enhance soil fertility, and sustain rice productivity in Ghana.
由于土壤养分极度贫瘠，加纳的水稻生产已难以为继。这是由土壤肥力管理不善造成的，包括肥料施用效率低下。一个切实可行的解决方案可能是生物肥料sp. B510。我们在加纳和日本进行了田间试验，以比较B510定殖对所选加纳水稻品种生长的影响。接种B510显著提高了水稻品种的生长和产量。在水稻品种Exbaika、Ex-Boako、AgraRice和Amankwatia中观察到的表型特征主要是株高较短和分蘖能力强。这些特征归因于分离出菌株B510的宿主植物（日本晴）。此外，该物种已被确定为加纳所有主要水稻种植区不同农业生态环境中水稻根际的优势定殖细菌。我们的结果表明，利用B510作为生物肥料是改善加纳水稻生长、提高土壤肥力和维持水稻生产力的一种有前景的方法。
