His discovery gave the key to the mystery,. J FIG. 42.—Double pots used in showing influence of Legume on non-legume. (After Lipman). -the non-legume was getting combined nitrogen from the legume. This was strikingly demonstrated by a very ingenious experiment conducted by Lipman. He grew non-leguminous plants in soil in a porous pot surrounded by earth in a larger glazed earthenware pot in which leguminous plants were growing and found that under* favorable conditions non-legumes associated with legumes may secure large amounts of nitrogen from the latter. This power of supplying nitrogen to non-legumes varies wth different legumes. At times it may appear as an increased yield, whereas at others it may appear as an increased proportion of nitrogen in the dry matter of the non-legume or both. The following table gives the per-.
