TABLE XVII — COMPARISON OF CORN VARIETIES FOR SILAGE — 

 GRANVILLE BRANCH STATION. 



*The varieties are ranked according to their food values. 



Several of tlie varieties have stood well in most of the tests. Among 

 these are Biggs' Seven-Ear, Weekley's Improved, Latham's Double, and 

 Southern Beauty. These varieties are also among the best grain pro- 



ducers grown in the State. 



SUMMARY 



During the past season corn variety tests were conducted on six of 

 the State Branch Experiment Stations. These stations are so dis- 

 tributed as to represent the more important soil types and climatic 

 conditions in the State. Among the forty-two varieties tested was a few 

 of the best varieties from neighboring States, several of the most popu- 

 lar varieties grown in the State, and a few varieties that are grown to 

 considerable extent in certain localities. The results of such tests should 

 furnish growers of that section with reliable information regarding the 

 yielding power of corns grown in the community. As a result of the 

 tests a fcAv growers have already discarded old mixed varieties for seed 

 of the better yielding uniform corns. 



The tables contain the detail results of the 1916 tests and compiled 

 results showing the average standing for the past three years. The 

 average results from three years testing should be of service in deter- 

 mining the best varieties for a section. Some of the old varieties such 

 as Marlboro, Biggs' Seven-Ear, "Weekley's Improved, and Cocke's Pro- 

 lific are still standing well in the tests. Among the promising varieties 

 which have only been tested a few years are Latham's Double, First 

 Generation Cross ITo. 182, and Jarvis Golden Prolific. 



The best variety of corn for silage is the one that produces the largest 

 quantity of digestible food per acre. Since the ears contain 63 per cent 

 of the digestible nutrients in silage it is important that an ensilage corn 

 produce a large quantity of ears as well as stalks and leaves.
