Abstract
Abstract A field experiment was conducted on Beulah sandy loam to determine the influence of applications of B, N, and K on the yield, nutrient concentrations, and occurrence of growth abnormalities in cotton ( Gossypium hirsutum ). Symptoms indicative of B deficiency had been observed on the site the previous year. Applied B increased yield only when N was applied. Applied N increased yield only in the presence of applied B. Potassium fertilization had no effect on yield. Generally the B concentration in the plant tissue was increased by applied B, decreased by applied N, and not affected by applied K. At the early boll and medium boll stages of maturity, applied B decreased the percent total N in the leaf petioles but had no effect on that in the leaf blades. At the early square stage, applied B decreased the percent total N in the petioles when N was applied but had no effect on N concentration when no N was added. At two of three stages of maturity, applied B decreased the occurrence of ringed petioles, an abnormality considered to be a symptom of B deficiency. Applied N generally increased the occurrence of ringed petioles. At the early square stage, applied K, in the absence of applied B, increased the occurrence of ringed petioles but had no effect on the presence of rings when B was added.
