“…A colorimetric assay is sometimes used as an alternative to measure B, based on the use of the chemical azomethine H (Wolf 1974), but this and other spectrophotometric methods for B analysis are prone to interferences by the presence of other elements, and colour (eg. leaf chlorophyll) in the sample (Sah and Brown 1997). Cheaper options for screening include assessment of vegetative biomass, relative root length and leaf symptom expression, which are all able to be conducted using simple laboratory and plant growth methods.…”

“…The reliability of B measurements has improved in the last decade with better instrumentation and analytical methodology (Sah & Brown, 1997). After spectrophotometry, B has been determined utilizing potentiometer, chromatography, flame atomic emission and absorption spectrometry, inductively coupled plasma (ICP) optical emission (OES) and mass spectrometry (MS), and neutron activation analysis using neutron radiography and promptactivation analysis.…”

“…Boron determination by ICP-MS suffers no spectroscopic interferences, and is considered the most practical and convenient technique for B isotope determination. Among the present technologies, ICP-MS has emerged as the method of choice for determining B concentration and a convenient method for B isotope determination (Sah & Brown, 1997). With the increased use of inductively coupled plasma atomic emission spectrophotometry (ICP) (especially instruments with simultaneous detection capability) soil test laboratories would welcome the need for different extractions for many element analyses.…”

“…O boro é um elemento essencial para o desenvolvimento normal das culturas anuais, participando de várias reações biológicas; sua deficiência é relatada em vários tipos de solo, em várias partes do mundo (Sah & Brown, 1997) além de, em diversas culturas anuais no Brasil, provocar grandes perdas de produtividade (Bataglia & Raij, 1990). Foram relatadas respostas de aplicação de boro em algumas culturas anuais em solo de cerrado (Galrão, 1984;Buzetti et al, 1990;Carvalho et al, 1996); entretanto, a maioria dos trabalhos tem avaliado o efeito de um conjunto de micronutrientes impossibilitando, portanto, concluir o efeito de cada elemento isolado (Galrão, 1991).…”

RESUMOForam conduzidos cinco experimentos em casa de vegetação, para determinação de teores adequados e tóxicos de B no solo e nas plantas de arroz, feijão, milho, soja e trigo, cultivados em vasos. Os tratamentos com B consistiram de 0, 1, 2, 3, 6, 12 e 24 mg kg -1 de solo aplicado para o arroz e milho, e de 0, 1, 2, 3, 6, e 12 mg kg -1 de solo para o feijão, soja e trigo. A produção máxima de matéria seca da parte aérea de arroz, feijão, milho, soja e trigo, foi obtida com a aplicação de 0,4, 2,0, 4,7, 3,4 e 0,4 mg kg -1 no solo, respectivamente, enquanto os níveis tóxicos de B aplicados com base na redução de 10% na produção, foram de 3, 4,4, 8,7, 6,9 e 7,4 mg kg -1 de solo, respectivamente, para as mesmas culturas. Conforme a análise do solo, os níveis adequados de B para o arroz, feijão, milho, soja e trigo foram 0,4, 0,9, 1,3, 2,6 e 0,4 mg kg -1 , respectivamente, mas a toxidez, nas mesmas culturas ocorreu quando a análise de solo mostrou teores de 2,3, 2,8, 5,7, 5,2 e 4,3 mg B kg -1 . Os níveis adequados na planta variaram de 10 a 75 mg B kg -1 e os tóxicos de 20 a 153 mg B kg -1 , dependendo da cultura.Palavras-chave: produção de matéria seca, comprimento das raízes, teor de B na planta, teor de B no solo ADEQUATE AND TOXIC LEVELS OF BORON FOR RICE, COMMON BEAN, CORN, SOYBEAN AND WHEAT PRODUCTION IN CERRADO SOIL ABSTRACTFive greenhouse experiments were conducted to determine adequate and toxic levels of boron in upland rice, common bean, corn, soybean and wheat. The boron treatments were 0, 1, 2, 3, 6, 12 and 24 mg B kg -1 of soil for rice and corn and 0, 1, 2, 3, 6 and 12 mg B kg -1 of soil for common bean, soybean and wheat crops. Maximum dry matter yield of the tops of rice, common bean, corn, soybean, and wheat was obtained with the application of 0.4, 2.0, 4.7, 3.4, and 0.4 mg B kg -1 of soil, respectively. Toxic levels of B, responsible for a 10% yield reduction were 3. 0, 4.4, 8.7, 6.8, and 7.4 B kg -1 , respectively for the same crops and, based on soil analysis, the adequate levels of B were found to be 0.4, 0.9, 1.3, 2.6 and 0.4 mg B kg -1 of soil. Similarly, the toxic levels of B in the soil for these crops were 2.3, 2.8, 5.7, 5.2, and 4.3 mg B kg -1 of soil, respectively. Adequate levels of B in the plant tissues varied from 10 to 75 mg B kg -1 and toxic levels varied from 20 to 153 mg B kg -1 of dry tissue depending on crops.
