 CHAPTER XII. 



WHITE MUSTARD. . 



One ton of white mustard contains y pounds of 

 nitrogen. In two months it will produce 15 tons 

 per acre of green manure. Two crops may he raised 

 from May to September, to be plowed in for wheat. 

 On a field of 20 acres you may have 600 tons at one- 

 tenth the cost of stable manure, and nearly equal in 

 it in value ton for ton. 



Joseph Harris says : '* On sanely soils, that are not 

 specially enriched by summer fallowing-, mustard 

 could undoubtedly be used i;o advantage as a green 

 manure for v/inter wiieat or ior Indian corn the next 

 spring." 



Again he writes; " The experience oi the heavy- 

 land farmers of Suffolk is in favor of sowing about a 

 peck of white mustard on the long fallows in August 

 or early in September, and plowing in the herbage 

 about six or eight weeks from, the time of sowing. 

 The effect upon the barley crop is considered by 

 practical farmers as equal to half a coat of farm-yard 

 dung, obtained at a cost of 2s. 6d for the seed. 

 Upon a clay loam the mustard being sown after 

 peas, and plowed in for wheat, the difference in the 

 crop was visible to the eye at a considerable distance 

 from the field At harvest, the wheat where the 

 mustard had been plowed in was six inches higher, 

 and ripened ten days sooner than wheat on adjoining 

 lands where no mustard had been sown, but other- 

 wise treated in a similar manner. ( Walks and 

 Talks, No. 100.") 



We see by these extracts, that white mustard
