Doc, Tifton 85 is another bermuda hybrid, and was developed in Georgia. It is not world feeder, and in fact has been found to be far superior to the world feeder product. The yield is even greater than coastal bermuda, and it has a very high tdn. <A target="_blank" HREF=http://aggie-horticulture.tamu.edu/plantanswers/turf/publications/foragebermuda/bermuda.html>Here</A> is a link to a study done by Texas A&M university showing the relative yields of some of the more common grasses used as forage and for hay. It is a fairly long article, but the jist of it is that world feeder gives about 75% of the yield of coastal, and Tifton 85 gives 145%. It seems that the self hype of the world feeder is not scientifically based. At least it does not grow like they say it does here in a couple of areas of TX. I am paying $160 per acre for the sprigging and rolling. For this price they are putting down 40 bushels per acre.
