Influence of Boron, Nitrogen, and Potassium on Yield, Nutrient Uptake, and Abnormalities of Cotton

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 tissu… Show more

“…as summarized in Table 1. Due to interactions between K and B (Miley, Hardy, Sturgis & Sedberry, 1969), B was included as a treatment;-Some-agronorilically important parameters in addition to those reported on previously (Davies & Combrink, 1986) were determined.…”

“…Nas plantas mais desenvolvidas no tratamento sem boro, surgiram anéis concêntricos, de verde mais escuro, salientes e com pilosidade intensa, intercalados com partes normais do pecíolo da folha, com necrose da medula nas áreas correspondentes aos anéis externos (2,3,8,10,11,14,18), conforme figuras 5 e 6.…”

“…Usualmente, os primeiros sintomas ocorrem nas partes jovens, nos tecidos de condução e nos órgãos de propagação, podendo inclusive ser constatados apenas nesses últimos (6). São verificadas desde alterações gerais nas flores -como clorose e deformação de brácteas, encurtamento e dobra de pétalas, necrose de estames e escurecimento e ruptura de nectários extraflorais (2,6,7,8,10,11,14), -até queda excessiva de botões florais e frutos novos (4,7,8,10,13,14). Quando o solo contém boro em quantidade suficiente apenas para o desenvolvimento vegetativo, pode ocorrer crescimento excessivo, semelhante àquele devido à abundante adubação com nitrogênio, porém, com frutificação bem prejudicada (6,7,14).…”
