68 HORTICULTURE BY IRRIGATION. 



Plant cucumbers on good soil and give them lots of water. They are 

 large yielders. 



ONIONS. 



Onr market gardeners report an occasional yield of this garden pro- 

 duct at the rate of a thousand bushels to the acre, but with an average of 

 from five to six hundred bushels. Onions are nearly always in good 

 demand with price not less than $1.25 per hundred pounds. 



No vegetable requires more careful treatment with regard to irriga- 

 tion. If not applied at the right time and in the right manner, injury is 

 sure to follow. In irrigating, water should never touch the plant, as it is 

 pretty certain to ruin it in any stage of growth. To avoid this it is best 

 to sow in ridges. 



Sow seed with drill from March 15th to April 1st. 



Plant two rows, six inches apart, on each ridge, with the ridges two 

 feet apart, using at the rate of four pounds of seed to the acre, on rich 

 ground. Give extra good cultivation. Scullions are numerous among 

 onions, some seasons probably the result of improper irrigation or poor 

 seed, or perhaps both. Good sets, as well as seed, can be grown in Colo- 

 rado. For sets, sow seed thickly, twenty-five or thirty pounds to the acre. 

 When up, and bulb begins to form, no more water should be given them. 

 This is a very important precaution, and one of the essentials of growing 

 good sets. After sets are grown plant them instead of the seed, and the 

 crop will not only be much surer, but will be ready for market nearly two 

 months in advance of seed-grown onions. 



The best variety for Colorado is the Eed Wethersfield and is really a 

 good onion, but its color is against it for market. Yellow Globe Danvers 

 is the best market variety for this section. 



PEAS. 



All of this family of vegetables thrive under irrigation and should 

 have plenty of moisture during the growing season particularly at the 

 period of blooming. 



The Little Gem and American Wonder are perhaps the best for a 

 summer crop ; the Champion of England for later. The latter is called 

 the best " hot weather " pea. 



Plant in drills three feet from row to row.
