IRRIGATION OF FIElvD CROPS. 243 



demands more frequent wetting and a forced habit of 

 growth throughout. We have reHed upon from four 

 to seven irrigations in a season of subsoiled land, and 

 have had the most flattering success when the water 

 was applied at least every fortnight from the first of 

 June. 



Turnips, Beets, and Carrots. — These may be 

 irrigated at any time,' the only care necessary being to 

 keep the ground mellow and in good tilth. Field tur- 

 nips for live-stock feeding should be sown broadcast 

 about the first of August. Set out the irrigating fur- 

 rows every six or ten feet, according to the porosity of 

 the soil, and have them run at an easy grade. Wait 

 long and patiently for the seed to germinate before 

 irrigating for that purpose. Never flood turnip, pars- 

 nip, or carrot ground, as the water would rot the 

 crowns ; undersoaking is the thing. Give frequent 

 irrigations until the root has fully formed. After the 

 plants are large enough to shade the ground irrigation 

 is scarcely necessary, and it might prove an injury and 

 cause decay. 



Such roots do best on black, loamy soil, containing 

 much decomposed vegetable mold, but like most crops 

 will grow anywhere and yield in proportion to land, 

 cultivation, and general conditions. The soil should 

 be thoroughly pulverized, leveled, and rolled before 

 sowing. Deep plowing is not necessary, and some 

 successful growers merely loosen the surface with 

 garden cultivators. Seed may be sown broadcast or 

 drilled in rows about fifteen inches apart. Two or 

 three pounds of seed will plant an acre. A slight 

 covering is sufficient, and some growers cultivate lightly
