'• Fresh manure si)re:ul in winter did not .iiive as much increase as the same 

 amount rotted and plowed down at same date in the spring. 



" Turning the manure while rotting was better than leaving it without being 

 turned. 



" Commercial fertilizers plowed under in the spring invariably gave larger 

 yields than when sowed on the surface .iust before planting in the summer. 



" About 750 lbs. of commercial fertilizers seemed to be more profitable than 

 three times that amount. 



" Continuous crops of sweet potatoes on same land does, not appear to be bad 

 1 tract ice. 



" The quality of the ci'ops, cabbage and potatoes especially, grown upon the 

 check plats, was of very poor grade. 



" The soil on plats heavily dressed with mineral fertilizers does not seem 

 to have been changed or injured any more than where the organic fertilizers 

 were applied. 



" The seasons through which this work has been followed have all been very 

 moist and some were quite wet." 



In the work with sweet potatoes, commercial fertilizer gave the best results 

 for the first three years. The results as a whole, however, appear to favor 

 the use of a combination of stable manure and commercial fertilizer. The 

 smaller quantity of stable manure (5 tons per acre) produced almost as lai'ge 

 a crop and gave much greater profits than larger applications of manure.

Chile culture, F. Garcia {New Mexico Sta. Bid. 67, pp. .',-32, figs. /()).— This 

 bulletin contains popular instructions for growing and harvesting chile, includ- 

 ing notes on diseases and insect pests. Tabular data are also given on the fol- 

 lowing chile experiments conducted at the station : Ridge v. level culture with 

 field-sown seed, field-sown seed v. transplanted plants from seed started in 

 cold frames ; yield and cost of production of green and red chile, and the 

 effects of sodium nitrate upon the yield. The results, however, are considered 

 only tentative as the investigations have not been conducted long enough to 

 i'.rrive at definite conclusions.
