Abstract:
Three plant growth regulators (two for growth enhancement, one for growth inhibition) were applied to several consecutive cuttings of alfalfa during the period of May-August in the Blythe, CA, area. All treatments resulted in reduced tonnage compared to the untreated check, although application of prohexadione calcium (active ingredient in the growth inhibition plant growth regulator) did result in increase in alfalfa quality when applied in May. Subsequent applications during the summer of this material did not result in a quality class increase for alfalfa hay production. Treatments of growth enhancement chemistries did result in less tonnage, however, data indicate that this reduction may be due to nutritional needs of alfalfa not being supplied during periods of increased growth. Supplemental nutrition along with the growth enhancement chemistries has not been tested to determine resulting alfalfa yields.
