The tomato is a universal favorite and in the United 

 States it is a regular and staple crop. It is a major forc- 

 ing crop. In most parts of the territory, it is grown out of 

 doors with the greatest ease. The soil should be rich but 

 not over-supplied with nitrogen, particularly if it becomes 

 available late in the season. It is commonly said that very 

 rich soil is not to be advised for the tomato. This is prob- 

 ably true as respects the heavy application of stable 

 manure; it usually gives up its fertility somewhat slowly 

 and tends to keep the plant in vigorous growth and to de- 

 lay fruiting. If, however, the soil has been made rich by 

 previous application of manure, or of available commercial 

 fertilizer early in spring, the best results may be expected. 

 Experiments at Cornell showed that a rather light single 

 application of nitrate of soda about the time the plants are 

 set, gives better results than twice that amount applied at 

 intervals as late as the middle of 

 August (page 382).

 from 1,000 to 1,200 pounds to the acre. Many farmers
