Abstract
Abstract Interactions involving macro and micronutrients modify plant growth, as indicated by induced deficiencies or toxicities and growth reductions. The objective of this study was to determine the influence of Mn and B and their interactions on micronutrients in leaf tissues of upland cotton ( Gossypium hirsutum L.). A 2 ✕ 11 factorial design included two B levels of 35 and 500 µg/liter and 11 Mn levels, varying from 0 to 4000 µg/liter in nutrient solution under greenhouse conditions. In blade 3, Mn tissue concentration less than the 10 µg/g critical level induced high Zn concentration of 127 µg/g in leaf tissue. As Mn concentration approached the critcial level, Zn concentrations decreased to 33 µg/g and remained constant with increasing Mn to 247 µg/g. Copper concentration was independent of Mn concentration. However, the reciprocal Mn‐Fe relationship was apparent where Mn concentrations of 4 and 247 µg/g were associated with Fe concentrations of 270 and 51 µg/g, respectively. Manganese nutrition had a small but significant influence on P concentrations where P concentrations of 2.37 and 1.84% were associated with Mn concentrations of 8 and 210 µg/g, respectively. The influence of B levels on micronutrient concentration in leaf tissue was not consistent. Low B induced lower Mn concentrations than did adequate B in young and recently matured tissue, whereas no effect of B levels on Mn concentration was evident in older leaf tissue. Low B induced a small but significantly lower Zn concentration in recently matured blades, while no effect of B nutrition on Cu was observed. However, low B induced higher Fe concentrations in old blades than did adequate B.
