lO GREEN CORN UNDER GLASS 



doing ; for should the plant become root-bound, it will be 

 stunted. They should be shifted from smaller to larger pots 

 should occasion require it. A corn plant, if left in a four-inch 

 pot, will tassel out when two feet or so tall. Only plants that 

 have made a healthy growth from the first are likely to give 

 satisfactory results. 



Distance to Plant. — As space under glass is valuable, it 

 follows that all of it must be utilized as far as possible. The 

 usual distance out of doors for average sweet corn is in rows 

 three feet apart, and the plants nine inches apart in the row. 

 An experiment was undertaken at the time of planting to 

 determine the most economical distance for planting in the 

 forcing-house. Six plots were planted as follows : In plots i 

 and 2, the rows were iS inches apart ; in plots 3 and 4, rows 2 

 feet apart ; in 4 and 5, rows 3 feet apart. All of the plants 

 were nine inches apart in the row. At maturity it was found 

 that from plots i and 2, the plants averaged one ear per stalk ; 

 from 3 the average was .9 ears per stalk ; from 4, one ear ; and 

 from 5 and 6 only .8 ears. Not only were there more ears 

 from those plots with rows 18 inches apart, but they were 

 equally as large and well filled. The silk formed on almost 

 every plant for a second ear but with no results excepting in 

 two instances. 



A plot was also planted with the rows only one foot apart, 

 and plants six inches apart in the row. This resulted in either 

 no ears at all or a mere nubbin. The cut on the cover of the 

 bulletin shows the twelve best ears out of the whole plot, only 

 four of which approached edible size. The forcing-house runs 

 nearly north and south, and the rows were made crosswise, or 

 nearly east and west. 



Ti-aining. — The only training thought necessary was to 

 check the suckers which seem to start out very early in some 

 of the varieties. These were easily pinched ofi^or cut out, thus 

 throwing the strength to the main stalk. We also found that 

 it is unnecessary to allow all the tassels to remain on in order 

 to secure sufficient pollen ; one-half could easily be dispensed 

 with. In so doing more strength would be thrown to the ear. 



Pollinating. — Sweet corn grown under glass readily polli- 

 nates itself; the only thing necessary is that the atmosphere be
