310 Annual Report Agricultural Experiment Station 



Horticultural Station and on the University grounds at Tucson, 

 with a view to stimulating a greater interest in home gardening as 

 a means of increasing the food supply. With good cultivation and 

 ample irrigation, tomato, eggplant, pepper, okra, carrot, and the 

 edible cowpeas were made to produce during the hottest portion of 

 the summer. Tomatoes did not yield a heavy crop during this 

 period, but shaded parts of the plants continued to bear some fruit. 

 Further tests will be made with summer vegetables with the hope 

 of adding other varieties to the list that can be successfully grown 

 during the hot weather of this season. 



Of special interest this year was the fall garden. Notes taken 

 October 25 in the garden at Tucson showed the following vege- 

 tables in edible condition : snap bean, chard, cucumber, cowpea, 

 carrot, endive, kale, lettuce, mustard, onion, radish, salsify, spinach, 

 tomato, and turnip. Other vegetables that were growing nicely at 

 this time, and that will be available for use during winter and early 

 spring are broccoli, cabbage, cauliflower, brussels sprouts, collard, 

 corn salad, kohlrabi, leek, parsley, parsnip, and rutabaga. All of 

 these vegetables were planted during the month of August and in 

 early September, except tomato, carrot, and salsify, which were 

 started in the spring.
