the maiib(u- o( cars par stalk. ISelcftin^ may go too far iu this directiou. 

 Since more than 50 per cent of the corn grown in the State is harvested 

 by hand, the extra hibor and waste necessary in the harvesting of a large 

 number of small ears and nubbins is very evident. The larger number 

 of ears arc usually accompanied by a large quantity of damaged grains. 



During the past season data has been secured on the number and 

 weight of good ears for each variety tested. Since the varieties hold 

 practically the same relation on each farm, the results from all of the 

 farms have been averaged and arranged in Table XL The varieties 

 are arranged according to percentages of nubbins by count. Biggs' 

 Seven-ear gave the highest percentage of nubbins and First Generation 

 Cross No. 182 the lowest. Xearly 43 per cent of the ears borne by 

 Biggs' Seven-ear were nubbins, and their weight amounted to 28.79 

 per cent of the total weight of ears. These results suggest some of the 

 advantages that may come from selecting our best two-eared varieties 

 for increase yield of grain per stalk, rather than increasing unduly the 

 number of ears per stalk. 



The question is often raised as to which is the best for ensilage, the 

 large one-eared corns or the prolific sorts. In answering this question 

 one should consider both the quantity and quality of material secured 

 from each. Although the large one-eared corns may produce a larger 

 quantity of ensilage the quality and food value is not so good as that 

 from the prolific varieties. The results of the variety tests furnish 

 some data for thi^ comparison. Although no weights were taken at the 

 ensilage stage, weights of the dried stover and ears should furnish a fair 

 comparison. Weights from four of the most prolific varieties and four 

 of the largest one-eared varieties are compared in Table XII. The four 

 prolific varieties gave an average yield of 2,6G9 pounds of dry stover 

 and 2,868 pounds of ears with a total yield of 5,537 pounds of dry 

 stover and ears. The four one-eared varieties produced an average of 

 2,425 pounds of dried stover and 2,247 pounds of ears, giving a total 

 weight of 4,672 pounds per acre. In these tests the prolific varieties have 

 produced a larger quantity of ears and stover. Eureka, one of the popu- 

 lar ensilage corns, produced 3,755 pounds of dry stover and 2,521 pounds 

 of ears, while Wcekley's Improved, a prolific variety, yielded 2,775 

 pounds of dry stover and 2,957 pounds of ears per acre. Though 

 Eureka produced more stover by 98Q pounds, Weekley's Improved 

 yielded more ears by 436 pounds per acre. Although the total yield from 

 Weeklcy's Improved is less than Eureka by 540 pounds per acre, its 

 food value is greater on account of its higher production of grain. 

 Other large varieties would no doubt yield more ensilage than the one- 

 eared varieties of this test. The larger corns, however, produce ensilage 

 of lower food value on account of their low yield of grain. In such 

 comparison one should consider the total food value rather than amount 

 of ensilage secured. The above results indicate that the prolific varie- 

 ties will produce a greater quantity of actual food per acre.
