Row Width Effects on Pasture Yields of Irrigated Sudangrass and Hybrid Cultivars
by D. C. Sumner
pp5, doi#10.3733/ca.v019n02p5
Abstract
Abstract Not Available – First paragraph follows: establishinc an annual irrigated pasture costs about the same as one based on perennial species. Therefore, every management opportunity should be taken to obtain maximum economical yields from the annual type, commensurate with the feed quality desired. One factor often overlooked by annual summer pasture operators that can favorably influence yield, is row spacing. It has been demonstrated many times that sudangrass stands are more productive when drilled than when broadcast. From experiments conducted under nonirrigated conditions in Illinois, it was determined that there was no significant difference in dry matter production of Piper sudangrass from row widths of 4, 8, and 16 inches. These trials were not harvested in the vegetative stage of growth as pasture but in the early bloom stage, nearing maturity.

A progress report…: Citrus rootstocks resistant to phytophthora root rot
by L. J. Klotz , W. P. Bitters , T. A. DeWolfe
pp10-12, doi#10.3733/ca.v019n02p10
Abstract
Abstract Not Available – First paragraph follows: valencia oranges observed on trifoliate rootstocks in this experiment at the Citrus Research Center, Riverside, and Valencia and navel trees in commercial orchards have performed well on this stock for many years; similarly, standard Lisbon lemon varieties have done well on trifoliate rootstock for the 13 years they have been observed. However, a high incidence of the exocortis virus in budwood of Eureka lemon and creasing of the bud union preclude its use on trifoliates or citranges.
