56 Progressive Agriculture 



Mr. Haun, at Haxton, Colorado, planted a 

 part of his corn May 4, 1915, and the rest of it 

 June first, with a similar experience, that of having 

 his later planting grow tallest and rankest and 

 maturing corn at about the same date as the 

 early planted. 



Mr. Forrest of Brush, Colorado, planted part 

 of his corn May 7, 1915 and the balance June 10, 

 all in the same field, with same seed, an early 

 maturing and acclimated variety. Four men were 

 selected to estimate the crop of the two plantings 

 on September twenty-fourth. They agreed that 

 the late planting had produced more than three 

 times as much fodder and more than two times 

 as much corn ; that the late planting was less than 

 one week behind in maturing although planted 

 five weeks later; and that the early planted field 

 was badly smutted while the later planting 

 practically had no smut. 



Similar conditions were reported as to the ab- 

 sence of smut in a number of other late planted 

 fields. Thus it would seem that the earlier planted 

 being more or less stunted and consequently less 

 vigorous and weaker was more susceptible to 

 disease than the late. This smut problem is a 

 question that is worthy of your careful considera- 

 tion, for it is very common some years in the 

 central west to find the majority of corn fields 

 developing much smut. The situation we have 

 just referred to indicates that a more vigorous, 

 healthy plant, the same as man or animal, has 

 greater ability to ward off or resist disease. We 

 have a number of letters from farmers expressing
