*Injured by frost. 



seedings of June 16 and 28 gave the largest production of 

 grain. * In 1905 the June 28 planting was injured by frost and 

 in 1904 the July 14 planting was killed by frost, so that no seed 

 matured. This experiment shows that it would not be a safe 

 practice to plant New Era cow-peas for seed later than the 

 25th of June, and that the best results year after year will 

 probably be obtained by planting from the 25th of May to the 

 10th of June. For the largest production of hay the cow-peas 

 should be planted a week earlier. The early planting of the 

 peas usually causes a heavy growth of vine and a decreased 

 production of seed. It is a safe practice not to plant until 

 about two to three weeks after the regular corn-planting time. 



When planting cow-peas with corn for ensilage our experi- 

 ments at this Station indicate that the best time for planting 

 the combination crop is about the first week in June. If 

 planted earlier than this, when the soil is cold, the cow-peas 

 start slowly and are thus apt to be covered and destroyed by 

 the early cultivation of the corn, or the corn, starting more 

 rapidly, outgrows the cow-peas which make only a dwarf 

 growth. If, however, the ground is permitted to warm up
