TYPES OF CORN BEST SUITED TO MASSA- 

 CHUSETTS.' 



p. H. SMITH AND J. B. LINDSEY. 



Since 1903 experiments have been in progress with corn to 

 determine those types best suited to Massachusetts conditions. 

 The total yield of dry matter per acre, digestibility, relative 

 proportions, in some cases the composition of the various parts 

 of the plant (stalk, leaf, ear and husk), and the relation of 

 stage of development to the relative proportion of different 

 parts as affecting the food value, have been carefully studied. 

 The following varieties have been tested: Twitchell's Early 

 Flint, Sanford White, Longfellow, Pride of the North, Rust- 

 ler Dent, Leaming, Brewer's, Early Mastodon, Klondike, Red 

 Cob Silage, White Cap Yellow, Wing's Improved White Cap, 

 and Eureka. 



The results of the study may be summarized under the fol- 

 lowing headings : — 



1. The stalks and ears form substantially TO per cent, of 

 the entire maize plant; most varieties showed about 20 per 

 cent, leaves and 10 per cent, husks. 



2. The Twitchell, a small early maturing variety, showed 

 an exceptionally large proportion of ears (55 per cent.)? 

 but it is not economical for Massachusetts conditions. The 

 medium dent and flint varieties (Pride of the North, Rust- 

 ler, Longfellow, Sanford White) averaged 33 per cent, of 

 stalk and 37 per cent, of ears, and are quite well suited for 

 grain, and serve fairly well for silage. The larger medium 

 dent varieties that in an average season bring their ears to 

 the milk stage, yield about 45 per cent, stalk and 26 per cent, 

 ears, and are rather preferable for silage purposes (Teaming,
