Ensilage Crops.
Corn is, of course, the standard crop for ensilage, and its relative importance in Florida is not far different from that in other States.
Under certain conditions sorghums will yield greater tonnage than corn, and the resulting silage is but slightly inferior.
Florida possesses, in addition, a unique silage plant in Japanese sugar cane. The perennial nature of this plant and its high yielding capacity make it a cheap fodder to grow. It may be utilized as green feed, as silage, as dry fodder, or for pasture. Your own experiment station has published the best information we have on this forage. As a feed for dairy cows there can be no question of its high value, either green or as silage. There still seems to be question, however, as to the relative value of Japanese cane silage as compared with corn silage. In Southern Florida the cane stays green all winter, as a rule, so that there is no necessity for ensiling it for winter feed. It may well prove, however, that a supply of Japanese cane silage will prove good insurance against periods of shortage even in South Florida.
You may have noted that all the pasture plants I have mentioned are grasses. Very unfortunately we have not as yet any good perennial pasture legume adapted to Florida. I say "unfortunately" because, as is well known, the true grasses are nutritious in proportion to the fertility of the land. That is, the better the land the more nutritious the pasture. But with legumes no such relations exist, because legumes are not dependent on the soil for their nitrogen supply.
While we have no satisfactory perennial pasture legume, we have one summer annual, lespedeza, that helps to some extent in North Florida. There are also two winter annuals that reproduce themselves in which I have considerable confidence, namely, burr clover and narrow-leaf vetch. I believe that on many of the better pasture soils, especially in North Florida, that these legumes can be established and that they will re-seed themselves year after year. Of course due care must be taken to secure inoculation, preferably by the soil method.
