Abstract:Low P availability is a vital constraint for nodulation and efficient N2 fixation of legume, including soybean. To elucidate the mechanisms involved in nodule adaption to low P availability under legume/cereal intercropping systems, two experiments consisting of three cropping patterns (monocropped soybean, monocropped maize, soybean/maize intercropping) were studied under both sufficient-and deficient-P levels. Our results demonstrated that intercropped soybean with maize showed a higher nodulation and N2 fix… Show more
