Effects of Applying Molybdenum to Soybean and Intercropped Maize on the Increase of Nitiogen and Yield

Molybdenum is an essential element consisting of nitrogenase enzyme complex. In our country there are many kinds of soil in which the content of available molybdenum is very low and som field trails have shown applying Mo fertilizer to be able to increase the yields of legume crops obviously. It has been indicated from some research results recently that the nitrogen fixed by legume crops can be absorbed by the intercroppedg crops,such as maize,sorghum etc. study on application of molybdenum to the intercropping system of soybean and maize has been reported in this paper,which demonstrated that applying Mo not only increased the nitrogen fixed and the yield of soybean,but also the content of nitrogen and the yield of maize in the intercropping system.For this reason, it has a great significance in crop yield increase to popularize this measure.
