“…From an agronomic standpoint, K deficiencies and excesses are financially and environmentally inefficient and have negative yield-impacting consequences. General characteristics of excessive K in cotton (Gossypium hirsutum, L.) include increased boll rot (Bennett et al, 1965), increased plant height (Bennett et al, 1965;Pettigrew and Meredith, 1997), and delayed maturity (Bennett et al, 1965;Gwathmey and Howard, 1998;Clement-Bailey and Gwathmey, 2007;Gwathmey et al, 2009). Deficiencies of K enhance water-deficit stress (Coker et al, 2000), reduce lint percentage (Pettigrew et al, 1996), dry-matter production (Gerardeaux et al, 2010;Rosolem et al, 2003;Zhao et al, 2001), plant height (Zhao et al, 2001), leaf area (Zhao et al, 2001;Gerardeaux et al, 2010), internode length (Gerardeaux et al, 2010), seed mass (Pettigrew et al, 1996), boll mass (Pettigrew et al, 1996), N-use efficiency (Pettigrew and Meredith, 1997), and lint yield (Stromberg, 1960;Pettigrew et al, 1996;Gormus, 2002;Read et al, 2006).…”
