One bushel of burrs weighs from 10 to 12 pounds. It has been stated 1 bushel of clean seed weighs 60 pounds. When sown in the burr, it is usual to sow 3 to 5 bushels per acre, but in some instances less is sown and in some more. When seed apart from the burr is sown 12 pounds per acre should suffice. In some instances it is sown on Bermuda sod, but the attempts to grow it thus have not always proved satisfactory. At the Louisiana Experiment Station it was found that the burr clover remained long enough and grew large enough to injure the Bermuda. Possibly closer grazing would have prevented such injury. When sown on Bermuda grass, June, July or August are the months chosen for scattering the seed. Burr clover is also sometimes sown in corn and cotton to provide winter grazing, but when thus sown the object more frequently sought is to enrich the land. Both ends may be accomplished in some degree. =Pasturing.=--Opinions differ as to the palatability of this grass. All are agreed that stock do not take kindly to it at first, but that they come to relish it at least reasonably well when accustomed to it. It is said to be relished less by horses and mules than by other domestic animals. It has been praised as a pasture for swine. It is more palatable in the early stages of its growth, and will bear close grazing, and also severe tramping. It will provide pasture for six months, but not so bountifully in the first months of growing as later. =Harvesting for Hay.=--Burr clover is not a good hay plant. Owing to the recumbent character of the growth it is not easily mowed, nor has it much palatability in the cured form. The yield is said to be from 1/2 to 1 ton per acre. =Securing Seed.=--In the Gulf States the seed matures in April and May. The plants grow seed profusely. Sown in October, stock may usually be allowed free access to it until March, and if then removed, it will spring up quickly and mature seed so profusely that when the plants die and partially decay seed may sometimes be collected in hollows, into which it has been driven by the wind. It is more commonly sown in the burr form, the form in which it is usually gathered. The more common method of saving the seed, as given by Mr. A. H. Beattie of Starkville, Mississippi, is to first rake off the dead vines so as to leave the burrs on the ground and then sweep them together with a suitable wire or street broom. It is then lifted and run through two sets of sifters of suitable mesh by hand to remove the trash swept up in gathering the seed. It is probable that other methods more economical of labor are yet to be devised when harvesting the seed crop. As much as 100 bushels of burrs have been obtained from an acre, but that is considerably more than the average yield of seed.
