BULLETIN 1127, U. S. M'.l'AKTMENT OF AGRICULTURE. 



seeding of varieties which have a lon<r growing period. The long- 

 grain varieties, which are late in maturing, show a greater tendency 

 to -hatter their grain than the short-gram rices that ripen at the 

 same time. The early-maturing varieties, which as a rule have long 

 grains, seldom shatter unless left standing too long after the irriga- 

 tion water has heen drained from the field. When maturity occurs 

 in late autumn there always is greater shattering, regardless of the 

 variety of rice. The agronomic characters, including yield, of the 

 11 varieties here described are given in Table 2. 



Table 2. — Average agronomic data and annual and average yields of seven new 

 and four long-established varieties of rice grown on tenth-acre plats at the 

 Rice Experiment Station, Crowley, La., during periods of varying length in 

 the 9-year period from 1913 to 1921, inclusive.
