Interaction of molybdenum, phosphorus and potassium on yield in Vicia faba

  • M. Z. Xia (a1) and F. Q. Xiong (a2)


In pot and field experiments at Xichang, China, in 1984–85, (NH4)2MoO4 applied alone or with KH2PO4 to Vicia faba var. major increased total N, soluble sugar and chlorophyll contents and photosynthetic rate. The growth of root nodules and N fixation were stimulated, and more assimilate was distributed to seeds. Treatment with (NH4)2MoO4 combined with KH2PO4 gave the highest total N, soluble sugar and chlorophyll contents, the most root nodules, fruiting branches, fertile pods and seeds/plant and the highest 100-seed weight, and consequently produced the highest seed yield.
