WHEAT IN ARGENTINA 221 



well adapted to Argentine conditions. The grain 

 is smooth, fat, dark colored, and keeps well in 

 shipment, a quality very desirable in export 

 wheats. It is grown to some extent in all the 

 regions, but its quality varies somewhat with the 

 soil and climatic conditions under which it is 

 grown. The Barletta wheat which is raised near 

 Buenos Aires is not as hard, and not of as good 

 milling quality, as the same variety is when grown 

 farther south. Another valuable feature of Bar- 

 letta wheat is its ability to stand long after it is 

 ripe without shelling out. Since labor is often 

 scarce in Argentina and the harvest is necessarily 

 prolonged, a wheat that can stand delay is in 

 demand. Barletta also resists climatic hardships 

 such as frost, drought, .and heat, and is less likely 

 to be damaged by rusts than are some other va- 

 rieties. Russian wheat has also proved successful, 

 especially in the south, although since its resist- 

 ance to shelling is not strong, it must be harvested 

 promptly when it is ripe. 



The Semi-Hard Wheat. - The semi-hard wheat 

 district lies to the south, at this time from latitude 

 38 to 42 south. This area, which was formerly 

 not thought to be wheat country, has been proved 

 by recent results to be well adapted to this crop, 

 and so the boundaries of the region are now being 

 pushed still farther southward. The climate cor- 

 responds to that of the hard winter wheat section
