GREEN CORN UNDER GLASS 



15 



out of doors. One of the earliest ; very dark green foliage, 5 

 feet high ; numerous suckers ; good-sized kernels, with small 

 cob ; good quality ; many ears under size. Yield averaged 

 almost one ear per stalk, running in size as shown in Fig. 5. 



No. 15, Fi7'st of All. — A new early to second early variety ; 

 ears good size and long ; cob rather large ; kernels medium 

 sized; stalk averaged 5I to 6 feet; quality fair. While one 

 of the heaviest yielders out of doors, it fell behind in the green- 

 house, producing at the rate of ei^ht- tenths ears per stalk. 



No. 26, Early Fordhook. — Not given a fair trial. Under 

 more favorable circumstances we believe it would do well. 



No. 10, Early Minnesota. — This variety was not as early 

 as most of the others, taking a longer time than Crosby's Early. 



From our experience with the above named varieties, I be- 

 lieve we can depend upon almost any variety that is desirable 

 out of doors, to be equally valuable under glass. Moreover, 

 if proper heat, moisture, and a rich soil be given, a crop will 

 mature in the greenhouse in a shorter time than in the garden. 

 In the forcing-house with the exception of light we can have 

 almost ideal conditions. With the use of the electric light, 

 even the cloudy weather of w^inter can be overcome to a degree. 



For other varieties of sweet corn, we w^ould ask the reader 

 to consult Bulletin No. 51. Two not in the test, which we 

 believe are worthy of consideration for growing under glass 

 are Early Beverly and Eastman's Early. Both were early 

 and desirable in the garden. 



If sweet corn proves to be a successful forcing-house crop, 

 doubtless as with the muskmelon, tomatoes, cucumbers, etc., 

 we can in a few years develop varieties that will be better 

 adapted for this purpose than any of our present ones. 



SUMMARY 



1. Sweet corn should be included in the list of vegetables 

 adapted for forcing under glass. 



2. The requisites for forcing corn under glass are practically 

 the same as those for forcing such plants as tomatoes, melons, 

 cucumbers, egg-plants, etc. ; a night temperature of not less 

 than 60° to 70°, and ten degrees or more higher during day. 

 Until pollen begins to fall the atmosphere of the house should 

 be kept moist ; the soil also should never become very dry.
