A Two Prong Approach to Tissue Sampling of Cotton during the Bloom Period

Research was conducted from 2012-2014, totaling 12 sites over that time frame, where nutrient levels during bloom were monitored for both cotton petioles and leaf tissue. The main objective of the research was to determine how nitrogen application rates and timing influenced nitrogen status during the bloom period. Four sites evaluated multiple application rates methods for applying phosphorus and potassium to cotton and the impact of each management strategy on nutrient status during the bloom period. Initial results indicate that using both petiole and leaf tissue nutrient concentrations may improve the precision of in-season managment decisions.
