FORCING DWARF TOMATOES UNDER GEASS 



In order to compare the dwarfs with the standard or tall 

 varieties, the following extract is taken from a summary of 

 extended experiments made by IMunson :* 



"Some varieties seem specially adapted for culture under glass, 

 while others fail to give satisfactory results. Why this is so we do 

 not know ; but for the purpose of determining the most promising, 

 we have grown several of the best known varieties for several seasons. 

 Naturally, as the days grow longer in April and May the fruit will 

 be of larger size and the product per plant will be greater than in the 

 case with the first crop in January and February. The figures given 

 below represent the average results obtained, including both crops, 

 for several seasons. Several other varieties — including Ignotum, 

 Perfection, Peach, Prelude, Dwarf Champion, etc — have been grown,, 

 but those named in the table have proved most satisfactory : '''

The foregoing data come from one who has made repeated 

 experiments, not only with varieties, but methods of culture, 

 selection of seeds, soils, fertilizers, etc. ; hence it can be 

 relied upon. These results, if anything, are high as it is 

 claimed by the writer that without bottom heat and upon 

 ordinary greenhouse beds a much less yield is produced. The 

 latter condition more nearly represents those of our own. 

 The above yields were from boxes with bottom heat and 

 trained to one stem. 



Comparatively speaking, therefore, our crop with the dwarfs
