NATIVE GRASS PASTURE YIELDS
The yield cages in the native grass pasture at the Station livestock farm were clipped for the tenth consecutive year. Table 10 gives the oven-dry weights of the forage obtained from the cages in a single late-season clipping. Type 5, which is on land no longer belonging to the Experiment Station, was not clipped this season. It is impossible to include this type in the clipping program any longer.
Production of native grass in the pasture was surprisingly good this year considering the fact that April and most of May were quite dry, and growth of the grass was very poor during the early part of the season. The native grass responded well to the late moisture. This year blue gama grass produced a larger portion of the yield than usual. This is the only late growing grass of importance in the upland portions of the pasture. The average production of all types was 1538 lbs. per acre, which is about the same as last season's production and slightly more than the 10-year average production of 1371 lbs. per acre for all types.
This does not give an entirely clear picture, however, of the actual yield status of
the pasture this year. The data in Table 10 show that production
on all types except one was less or about the same as last year, and that production on
one of the most important types, Type 8, was less than half that of last year and only
about two-thirds the average production of this type.

|1Type 5 is no longer included
in the pasture.
The 8-year average yield of this type is 863 lbs. per acre.
2Yield considerably increased because of sweetclover grown to maturity in cages.
Taken on the overall basis, production on the Station native grass pasture this year should be rated about average or possibly a trifle below average.
Production on Type 7, the big bluestem type along the watercourse, was unusually high this year. This production was not the result of unusually good grass production, but rather the result of an unusual development of sweetclover inside one of the cages. There was some sweetclover in all the cages, but production by this species was very heavy in one of the cages, where it had grown to full maturity.
