MAIZE. 



From experiments in planting maize, made at the Indiana Agri- 

 cultural Experiment Station (see Agr. Sci., Vol. Ill, p. 192), the 

 following results were deduced : 



Planting on May 1 gave a loss at harvest of 5.47 bushels per acre: 

 planting on May 21 gave a gain of 0.31 bushels per acre. 



Deep plowing in 1880 and 1888 gave an increase over shallow 

 plowing of 2.4 bushels per acre, and 0.1 bushel in 1888. 



Deep culture with a cultivator of 3 to 4 inches gave better results 

 than a shallow culture of from 2 to 3 inches. 



As to rate of planting or density of stand, two kernels every 

 28 inches apart and three kernels every 36 inches apart seem to give 

 the best results for hand planting. For machine planting, the best 

 results were given with stalks 12 and 14 inches apart.
