A com-plete fertilizer at the second stage produced larger spikes than oneapplied at planting. The peculiar thing is that where no fertilizationwas given the average length of spikes was greater than where acomplete fertilizer was added when the grain was planted. (SeeFig. 29.) The later applications of a high nitrogen fertilizer to the low mois-ture soil have not proven beneficial as compared with this form ofnitrogen applied at time of planting, the length of spikes being re-duced.
