The Effects of Three Plant Growth Substances on DPL 90

Foliar fertilizers and plant growth regulators have proven to increase yields in some crops such as grapes and tree fruits. Foliar applications of essential plant nutrients have given inconsistent results in cotton. Plant growth regulators, such as PIX, have proven to be effective cotton management tools. To evaluate their effects on cotton yields, commercially available substances from BioHumaNetics, Burst Agritech and the Westbridge Research Group were applied to DeltaPine 90 grown in a field managed by Claude and Mike Evans in Casa Grande. Each compound was evaluated in separate randomized complete block experiments. The field was planted on 5 April with a spot planting on 27 April.
