Food for mediately available Nitrogen, causes not only an in- 



! crease in the yield and marketable quality of the entire 



54 crop, but it materially increases the quantity of early 



fruit. The results of four years' experiments show 



that, by this method, the value of the increased yield 



of what may be regarded as extra early fruit averaged 



about $45 per acre. 



As in other cases , care should be used 



Nitate. in the a PP lication of Nitrate; it should 



not come in too close contact with 

 the plants, and, if broadcasted after the plants are 

 set, it should be done when they are dry, so that all 

 of the Nitrate may reach the soil. Where a larger 

 quantity is used, as, for example, 300 pounds or more, 

 it is very desirable that fractional dressings should be 

 made, though care should be used not to make the 

 second application too late, as it encourages a later 

 growth of plants and retards maturity. 



Cabbage is a gross feeder, and 

 ^ e * the crop can utilize large quantities of 

 plant-food to good advantage. The experiments with 

 this crop show that even where the land has been fer- 

 tilized with what would be regarded as reasonable 

 amounts of fertilizers adapted for the purpose, extra 

 dressings of Nitrate have given very profitable returns. 

 The yield has been increased from 40 to 80 per cent, 

 and the net value of crop from $53 to $80 per acre. 

 The experiments also show that what may be regarded 

 as a large quantity of Nitrate, namely, 400 pounds per 

 acre, is superior to any smaller quantity, and further, 

 that this had better be applied in two rather than in 

 a greater number of fractional dressings, as the later 

 applications have a tendency to disproportionately in- 

 crease leaf growth and retard heading. The most re- 

 markable effect of the Nitrate is shown in the influence 

 it exerts upon the marketable quality of the crop. In 

 the experiments conducted the addition of Nitrate re- 

 sulted in more than doubling the value of those heads 

 which were marketable that is, where no Nitrate was 

 applied, $1 per hundred was received, and where 400 

 pounds of Nitrate were used the price was $2.50 per 

 hundred. These results suggest a reason for the lack
