In a(bliti(»n lo exiKM'iniental plots we plant every year 

 considerable areas of cowpeas, both broadcast and in 

 drills. In decidinjr on the best method of planting in this 

 ^^<;en(U'al crop" we are *;overn(Ml by the price and avail- 

 able supply of seed and labor. We nse four to six pecks 

 of seed sown broadcast and two or three pecks in drills. 

 In sowino- broadcast we seldom plow in the seed, as in 

 the above-described experment, bnt sow them on .the 

 plowed land and cover seed and fertilizer with disc har- 

 ]-ow or with one-horse cultivator. 



In planting- in drills we open the drills in plowed or 

 implowed ground, and are careful either to apply the 

 fertilizer in the covering furrow or else to mix it with 

 (the soil before the seed are dropped. 



AVhere the ground has been plowed, the combined grain 

 drill and fertilizer distributor would doubtless be sat- 

 isfactory, stopping most of the tubes if it is desired to 

 drill the seed in rows wide enough for cultivation. 



Our observations lead to the belief that in unfavorable 

 seasons drilling and cultivation gives the largest yield 

 of hay (and always of seed) and that in seasons of 

 abundance of rainfall broadcast planting affords the 

 greater amount of hay, but not of seed. 



Varieties. 



During each of the past six years one or more tests 

 of varieties of cowpeas have been undertaken. Some of 

 these tests have been vitiated by agencies that need 

 not be stated here, and only those are^here reported 

 ^vhich have been free from inequalities and errors.
