This is one of the great root crops of England, and to considerable extent in this country, for feeding purposes. We think it should be displaced, mostly, by beets, carrots, and parsnips. They are more nutritious, as easily raised, and more conveniently fed. The Rutabaga is a productive variety, and possesses a good deal of nutriment. The essentials in raising good turnips of most varieties, are very rich soil, worked deep, and finely pulverized. They should stand in rows two feet apart, and one foot apart in the rows. They may be mainly tended with a small cultivator or root-cleaner. English turnips are extensively grown as a second crop on wheat stubble, &c. The soil is highly enriched and the seed sown in rows to allow cultivation. The best method, however, is to turn over old greensward say June 1, and yard cattle or sheep on it till July 10, and then harrow thoroughly, and sow the seed broadcast. The yield will usually be large, and they will need very little weeding. If it is not convenient to yard cattle on the turnip-ground, apply fifteen double wagon loads of fine manure with a few bushels of lime to the acre, and the crop will be large. The usual time of sowing turnips is from the 10th to the 25th of July. We think the yield is larger when sown by the middle of June. The only way to get good early turnips is to sow them very early. The flat, or common field turnip, is easily grown on new land, or on any rich soil tolerably free from weeds and not infested with worms. WHEAT.
