Evaluation of Palisade as a Plant Growth Regulator in Durum, 2016
MetadataShow full item record
AbstractLodging has historically been a problem in small grain production. Palisade is a relatively new plant growth regulator that has shown some promise in reducing lodging. The effect of Palisade on height and lodging of durum, and subsequent yield was tested in a study at the Maricopa Ag Center. Plant height was not affected by Palisade since the chemical was applied at boot, one stage past the recommended window where the plant was near maximum height. Lodging was reduced from 83 to 61% and 28 to 8% under the high and medium input growing conditions, respectively. Grain yield was increased from 4481 to 6152 lb/acre and 5600 to 7330 lb/acre under high and medium input growing conditions, respectively. Palisade is effective in reducing but not eliminating lodging, and can have a large impact on yield as in this study.
