334 CULTURE OF FARM CROPS. 



advisable to have a surplus supply, which may be secured 

 by having an extra seed-bed. If the plants of this extra bed 

 be not all used, they will be found most valuable for filling 

 up blanks in the swede or mangold fields. If a succession 

 of crops is required, the second set of plants should be 

 dibbled in drills by themselves, and at a less distance 

 apart, so that the largest number of plants may be grown 

 on a given plot of ground. The seed should be sown at 

 intervals for successioiial crops, so that the plants may not 

 be too far advanced for the later transplantings. Tile first 

 sowing should be made early in March, the second during 

 the first or second week in April, with a third, the first 

 week of June. These sowings may be transplanted re- 

 spectively, the first in May, at 18 inches apart; the second 

 in June, at 1 6 inches ; and the third at the end of July or 

 beginning of August, at from 12 to 14 inches, according 

 to soil and climate. The following may be taken as a 

 summary of the principal points connected with the cul- 

 tivation of this important root. 



136. Quantity of Manure to be applied to the Land. 

 Ten loads of farmyard manure to the acre; 4 or 5 cwt. 

 of good artificial manure (such as blood manure, super- 

 phosphate, rapecake, or the like), to be drilled down the 

 ridge, or scattered on the manure. (Mr. Bennett of Cam- 

 bridge, vol. 20, p. 469, Journal of the Royal Agricultural 

 Society.) Not less than 25 tons of farmyard manure, with 

 6 cwt. of good superphosphate, and 2 cwt. of common salt ; 

 4 cwt. of Phospho-peruvian guano may be added with ad- 

 vantage in place of the superphosphate. To insure equal 

 distribution of the guano in the soil, mix it with sand or 

 fine ashes. (Lawson and Son, vol. 20, p. 518, Journal of 

 the Royal Agricultural Society.) 



137. Fifteen loads of farmyard manure, and 2 cwt. of 

 Proctar and Eyland's turnip manure per acre. (Mr. Innes, 

 Colonel North's Wraxton Abbey.) 



138. Quantity of Seed to le Soivn. When raised in a seed- 

 bed for transplantation, a plot of 6 yards square' raising 

 sufficient plants for an acre, eight ounces of ~$eed will be
