Effect of Weeds on Yield and Quality of Produco. 



Th« Minnesota Station (Bui, 68, 588) "in 1898 planted corn 



in drills ia two plats in a similar manner, the plats being 



run In duplicate. On one plat the corn was cultivated 



thoroughly, no wetds being allowed to grow, and a loose 



mulch of earth two or three inches deep was mainteined 



throughout the early part of the summer. The other plat 



received but slight cultivation, the waeds being allowed 



to grow freely until July 21, when they were reaioved by hand 



and the soil cultivated." The weeds grown were mostly 



• 

 pigeon grass, and were mature whan harvested. The results 



are shown in Table I.

A yield of 3540 pounds of weeds reduced the yield 

 of com fodder (stover and ear eorn) 5773 pounds or 45 per 

 cent I the reduetlon in the yield of ear corn was 2232 

 pjmnds or 46 per cent. The percentage of ear corn was 

 nearly the same in both cases. The rate of reduction in 

 yield due to weeds was 1.69 pounds corn fodder for each
