Food for [hat peppers continue to form during the entire period of 

 plants gj-Q^rfh, the distribution of the Nitrate throughout the season 

 ^32 is desirable where large quantities are applied. Where more 

 convenient the first appHcation of Nitrate may be applied at 

 time of setting the plants, in order to prevent any delay in 

 grow^th after setting. The later fractional applications are 

 distributed throughout the season, two or three weeks apart. 



In the growing of early potatoes it is essen- 

 ' tial that an abundant supply of Nitrogen 

 be at the disposal of the plant. The experience of growers 

 has clearly demonstrated this fact, and, until commercial 

 fertilizers came into general use, most growers used large 

 quantities of yard manure, in order that the plant should 

 suffer no lack of this element. With the introduction of 

 commercial fertilizers, the question of greatest importance 

 has been the source of Nitrogen best suited to meet the 

 demands of the special early growth. The experiments 

 which have been conducted with a view to answering this 

 question have shown clearly that while Nitrate is most use- 

 ful, a combination of the Nitrate with quickly-available 

 organic forms, as dried blood, or with both organic and 

 ammonia forms, is preferable to the use of any single form. 

 M tVi ri f ^" good potato soils, therefore, a good 



_ . fertilization should consist of from 800 to 



1,000 pounds of a fertilizer contammg 

 Nitrogen, 4 per cent.; available phosphoric acid, 8 per cent.; 

 and potash, 10 per cent.; one-third of the Nitrogen at least 

 to be derived from Nitrate of Soda and the remainder from 

 quickly-available organic forms. On soils in good condition 

 the fertilizer may be applied in the row at the time of plant- 

 ing, though many prefer to apply one-half of the desired 

 amount broadcast previously and the remainder in the row 

 with the seed. Where there appears to be a deficiency of 

 Nitrogen, due to the fact that Nitrates have been carried to 

 lower levels by rains, or to the fact that the season has not 

 permitted the change and appropriation of organic forms, 

 then the application of 100 pounds of Nitrate per acre at the 

 time of blossoming will encourage the rapid growth of tubers, 

 though retarding, to some extent, the time of ripening.
