It was noted in the early season during a wet 

 and rather cool period that the plants on this plat

EFFECT OF S CRAP III G 

 Plat 2 was not cultivated after planting but 

 the weeds were prevented from growing by cutting them 

 off at the surface of the ground, taking care to leave 

 no mulch. The yield of corn fodder, dry matter, was 157 

 pounds less than normal as calculated from checks.
