In a five year's test in Iowa, the results have been as follows : TABLE NO. 36 **SHOWING PER CENT OF BARREN STALKS AS AFFECTED BY THICKNESS OF PLANTING.

This has been found to be particularly true in dry years. The effect of barren stalks on yield is well shown in the following table .giving the results of an experiment conducted in Ohio* in SINGLE ROW COMBINED LISTER AND DRILL. Used in very dry soils in order to get the corn deep into the ground so as to obtain moisture. TABLE NO. 37 SHOWING RELATION OF BARREN STALKS TO YIELD Per cent of Barren Stalks yield per acre, bushels Per cent of Stand 75 76 74 . 74 71 74 From the above table it is seen that as the per cent of barren stalks increase the average yield of corn decreases. It should be stated how- ever, that planting too thick on a thin soil, or in a dry season, tends to increase the per cent of barren stalks.
