give them a chaDce to hold to one another and thus 

 form supports. The ordinary practice is to make a 

 row about six inches wide, by scattering the seed 

 along a furrow, and covering about an inch deep. 

 Peas sown later than the first of January are liable to 

 come into competition with those grown farther north. 

 Cultivation is needed more to get air into the soil 

 than to keep the weeds down. During cultivtaion the 

 soil should be gradually worked up to the row so as to 

 leave them hilled up at the last plowing. The dis- 

 tance between the rows should be about twenty inches 

 for strong soil. 



FERTILIZER FORMULA. 



Available phosphoric acid 7 per cent. 



Potash 7 percent. 



Nitrogen 3 per cent. 



Use 600 to 1000 pounds to the acre. 



For this crop it will be found desirable to use min- 

 eral fertilizer rather than compost. If nitrate of soda 

 is used it will require two applications one at the 

 time of sowing, and the second just as the first flower 

 buds begin to show. Cotton-seed meal can be used as 

 a source of nitrogen before planting, as a portion of a 

 compost fertilizer. Nitrate of soda will cause the 

 vines to make a vigorous growth, so should not be ap 

 plied when a frost is looked for. 



The following amounts of fertilizing materials may 

 be used to obtain the amounts of each of the fertilizer 

 elements called for in the formula : 



Element. Pounds of different materials for one acre. 



T300 to 500 Ibs. cotton-seed meal ; or 

 v . f j 180 to 300 Ibs. dried blood ; or 



1 120 to 200 Ibs. nitrate of soda; or 



I 100 to 150 Ibs. sulphate of ammonia. 

 500 to 900 Ibs. of kainit ; or 

 80 to 140 Ibs. muriate of potash ; or 



Potash. 



90 to 150 Ibs. sulphate of potash ; or 

 160 to 240 Ibs. sulphate of potash, and 



sulphate of magnesia. 

 / 420 to 700 Ibs. acid phosphate ; or 

 onc acid \350 to 600 Ibs. dissolved tone.
