- Intervention effect P additions significantly increased yam bean growth and tuber production.
- Intervention effect Ca and K combined with P increased yam bean growth and tuber production.
- Association Nodule weight and nitrogenase activity responded to soil treatments similarly to tuber and aboveground growth.
- Intervention effect P, Ca and P + Ca significantly increased tuber epidermal ureide content.
- Intervention effect Tuber epidermal ureide content rose quadratically with K additions combined with P and Ca treatments.
- Association A multiple regression of nitrogenase on top, tuber and nodule weight and ureide yielded R2 of 0.88.
- Intervention effect Soil treatments did not significantly affect tuber nonstructural carbohydrate percentage.
- Intervention effect P treatments significantly increased total tuber nitrogen content.
- Intervention effect Nodule cytosol nutrient elements generally increased with addition of the corresponding soil element.
- Intervention effect Nodule potassium content rose quadratically with increasing potassium additions.
- Recommendation Adequate soil P, Ca and K favored tuber growth and nitrogen fixation, with P first limiting high tuber yields.
