Comments on the table-——As in previous years, the gain from 
spraying in this:experiment was smaller than in the experiment 
at Geneva. On the average, five sprayings gave more than 
twice the gain from three sprayings. In each section both of 
the sprayed rows outyielded the unsprayed row and the row 
sprayed five times outyielded the row sprayed three times.
