SWEET CLOVER may be utilized for feeding purposes, aspasturage, hay, or ensilage. With the possible exceptionof alfalfa on fertile soil, sweet clover, when properlyhandled, will furnish as much nutritious pasturagefrom early spring until late fall as any other legume. It seldomcauses bloat.
Stock may refuse to eat sweet clover at first, but this distastecan be overcome by keeping them on a field of youngplants for a few days.
As cattle crave dry roughage when pasturing on sweetclover, they should have access to it. Straw answers thispurpose very well.
An acre of sweet clover ordinarily will support 20 to 30sholes.
On account of the succulent growth, it is often difficult,in humid climates, to cure the first crop of the second seasoninto a good quality of hay.
When seeded without a nurse crop, one cutting of haymay be obtained the first year in the North and two orthree cullings in the South. Two cuttings are often obtainedin the South after grain harvest. The second yeara cutting of hay and a seed crop usually are harvested.
Sweet clover should never be permitted to show flowerbuds before it is cut for hay. It is very important thatthe first crop of the second season be cut so high that a newgrowth will develop. When the plants have made a growthof 36 to 40 inches it may be necessary to leave the stubble10 to 12 inches high.
In cutting the first crop of the second season it is a goodplan to have extension shoe soles made for the mower, sothat a high stubble may be left. In some sections of thecountry sweet clover as a silage plant is gaining in favorrapidly.
This crop has given excellent results as a feed for cattleand sheep. Experiments show that it compares favorablywith alfalfa.
Sweet clover has proved to be a profitable soil-improvingcrop. The large, deep roots add much humus to the soiland improve the aeration and drainage. As a rule, the yieldof crops following sweet clover is increased materially.
Being a biennial, this crop lends itself readily to shortrotations.
Sweet clover is a valuable honey plant, in that in all sectionsof the country it secretes an abundance of nectar.
This bulletin discusses only, the utilization of sweet clover.A discussion of the growing of the crop may be found inFarmers' Bulletin 797.
