FIELD CROPS. 



33 



were removed from alternate stalks iii each row. Two plats were not 

 detasseled. The variety used was Piasa Queen, a medium early yellow 

 eoru planted at distances of 16 in. by 3^ ft. On the plats from which 

 the tassels were removed on alternate rows the detasseled rows yielded 

 114.55 lbs. of corn, the rows with tassels entire 185.75 lbs. Where only 

 the first tassels were removed the yield per plat was 329.57 lbs. On the 

 l)lats from which the tassels were remov^ed from alternate stalks the 

 detasseled stalks yielded 71.77 lbs., and the stalks not detasseled 151.G1 

 lbs. On the plats not detasseled the yield per plat was 357.30 lbs. 

 "Owing- to the unfavorable weather at the critical period in the growth 

 of the crop there was scarcely pollen enough produced to fertilize the 

 ears, even had all the tassels remained, and removing them made the 

 evil worse." These results are opposed to those secured in 1892, when a 

 gain resulted from detasseling. 



Distance (pp. 138-142). — An experiment to determinethe best distance 

 between rows and between plants in the drill occupied 70 plats. The 

 largest yield of marketable corn resulted from planting at distances of 

 16 in. by 4 ft. 



Seed corn from different parts of the ear ( pp. 143, 144). — This experiment 

 in which " Dole ninety-day corn " was used occupied 15 plats. In 1893, 

 contrary to former results, the kernels from the tip of the ear gave the 

 largest yield of corn. Tlie following table gives the average yield of 

 corn for 3 years resulting from planting the kernels from the butt, tip, 

 and middle of the ear:

Methods of planting and cultivatinf/ (pp. 144-146). — This experiment 

 occupied 30 plats, and embraced (1) listing vs. surface planting and (2) 

 deep, shallow, and surface culture, and combined deep and shallow 

 culture. The variety was Farmer Favorite. For deep culture the two- 

 horse cultivator with 4 shovels was used, and for shallow culture the 

 Daisy spring-tooth cultivator with 8 small shovels. For surtace cul- 

 ture the plats were simply scraped with the Tower cultivator. Com- 

 bined deep and shallow culture consisted of deep culture for the first 

 and last cultivation and shallow culture for all others. The difierences 

 between the yields resulting from different methods of planting and of 

 cultivation were slight. The largest yield m 1893 was secured on the 

 listed plats cultivated deep. The largest average yield for 2 years was 

 from the surface-planted plats cultivated shallow.
