Other claims from this paper (8)

Intervention effect In the dry season, nitrogen fertilization plus inoculation increased shoot dry weight over inoculation alone.
Intervention effect In the dry season, nitrogen fertilization plus inoculation increased pod number over inoculation alone.
Intervention effect In the dry season, nitrogen fertilization plus inoculation increased yield over inoculation alone.
Intervention effect In the rainy season, combined nitrogen fertilization and inoculation did not increase shoot dry weight over inoculation alone.
Intervention effect Inoculation alone produced a greater number of nodules.
Intervention effect Nitrogen fertilization did not affect nodule weight in either season.
Recommendation Authors recommend sowing nitrogen fertilization with inoculation to improve dry season yield.
Recommendation Authors recommend inoculation without nitrogen fertilization for high rainy season yield at lower cost.
