36 FORCING POLE BEANS UNDER GLASS 



have been made a success, surely the best pole varieties, being 

 more productive, cannot help from becoming a profitable 

 crop under similar conditions. 



SUMMARY. 



1. Pole beans should be included in the list of vegetables 

 adapted for forcing under glass. 



2. The requisites for forcing pole beans under glass are 

 practically the same as for bush beans, sweet corn, melons, 

 cucumbers, etc. ; a night temperature of not less than 60° with 

 10° or more higher during the day. The house should be kept 

 moist, and the soil likewise should never become very dry. 



3. The house adapted for forcing pole beans should have 

 considerable space above the beds, ranging about eight feet. 



4. Pole beans thrive well in almost any good fertile green- 

 house soil. In this respect they resemble corn. 



5. The time from germination until maturity varies with 

 different varieties. The range for those tested was from 54 to 

 62 days. 



6. Much time is saved by starting the seed in pots, precau- 

 tion being taken not to allow the plant to become pot bound 

 before transplanting. The plants should be in their permanent 

 positions before they begin to run. 



7. The varieties that were found to do well when tested were 

 Mastiff Golden Pod, Early Golden Cluster and Golden Cham- 

 pion, named in order of productiveness. 



8. A cord trellis is preferable to the ordinary bean pole for 

 training up the plants. They are more evenly distributed by 

 the use of the cord and, too, the shade from the pole is avoided. 



9. Practically no trouble from insects or fungus attended the 

 growing of this crop. One variety developed a slight ten- 

 dency to pod rot at the last picking. Red spider and mite, 

 which have been reported as troublesome in forcing dwarf 

 beans, are kept in check by maintaining a moist atmosphere. 



10. Where bush beans can be made a success as a main 

 crop, with a house adapted for them, pole beans we believe, 

 will be found much more productive, area for area, and hence 

 more profitable.
