SUMMARY In pot and field experiments at Xichang, China, in 1984–85, (NH 4 ) 2 MoO 4 applied alone or with KH 2 PO 4 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 (NH 4 ) 2 MoO 4 combined with KH 2 PO 4 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.
