To determine the optimum time to plant, White Wonder corn 

 was seeded on six dates, as shown in Table LXXV, ranging from 

 March 29 to August 15. A perfect stand was secured in the March 

 planted plot, the soil being moist to within an inch of the surface. 

 In April and May the corn was planted three and one-half inches 

 deep. In June and July a heavy sub-mulch crust was formed, 

 which was broken with a 6-inch pony plow so that the seed might 

 be planted in moist soil. The resulting stand was poor. A shower, 

 occurring just after the July planting, formed a crust on the sur- 

 face of the soil, which prevented many plants from coming up. 

 The August planting was too late to allow the corn to mature. 

 Table LXXV indicates the desirability of early planting in spite of 

 the drought usually encountered in May and June. 



To determine the optimum rate of seeding, six plots of Mixed
