SynopsisSimple correlation was 0.84 between growth and daily mean temperature within the range of 47° to 67° F. It was 0.74 between growth and daily mean solar radiation within the range of 214 and 491 langleys. Several multiple regressions of growth on various expressions of temperature and solar radiation were studied. The equation Ŷ = −495.72 + 17.0285x1 − 0.1306x2, where X1 = temperature and x2 = temperature2, appeared best suited for predicting growth rates of forage in ryegrass pastures.

SynopsisSeed yields of five Trifolium species were inadequate when honeybees were excluded. A commercial variety of Trifolium resupinatum L. produced an adequate amount of seed with honeybees excluded, but yielded twice as much seed if honeybees were present.

SynopsisSuperphosphate, basic slag, and rock phosphate significantly increased the yield of forage as well as the protein and phosphorus contents, but an annual application of P2O5 as superphosphate was superior to the other treatments.

AbstractThe effects of various rates and frequencies of application of rock and superphosphate on the yield and chemical composition of pasture forage was studied on a Lake Charles clay loam soil. The amount of P2O5 in pounds per acre from each source and the frequency of fall application of this amount were: 30 lbs. every year, 60 lbs. every 2 years, 120 lbs. every 4 years, 240 lbs. every 8 years, and 480 lbs. every 16 years. The area was seeded to a pasture mixture of Dallisgrass and white, Persian, and hop clovers. Yield and chemical data are reported for the first 4 years, 1950–53. At the end of the fourth year, 4 yearly 30‐pound applications and two 60‐pound applications of P2O5 from superphosphate had equalled and surpassed the production from single applications of 120 and 240 pounds of P2O5 from the same source. There appeared to be a similar trend with rock phosphate; however, the yearly 30‐pound application has not proven very effective to date.
