Photothermal and nodulation effects of soybean crops. Photothermal effect: As soybean is a short-day and thermophilic plant, the robust growth and high yield of this crop can only be achieved under suitable photothermal conditions. In Africa, the too short daylength and heat waves can hasten soybean flowering and maturation, leading to low dry matter accumulation and grain yield compared with that in countries with optimal photothermal environments for soybean growth, such as Brazil, the United States, Argentina, and China. Nodulation effect: African soils lack compatible rhizobia for the effective nodulation of soybean plants for optimal grain yield. Therefore, inoculants are required to induce nodulation and N2 fixation for increased growth and yield, presenting challenges related to transport logistics and inoculation skills, among others.
