Abstract:RESUMOO trabalho foi desenvolvido com o objetivo de avaliar a produtividade e qualidade de tubérculos de batata em resposta ao boro em amostras de um Latossolo Vermelho (LV) e de um Cambissolo (CX). O delineamento experimental foi o de blocos casualizados, em esquema fatorial 4 x 2, constituído de quatro doses de boro (0,0; 0,75; 1,50 e 3,0 mg dm -3 ) e duas cultivares de batata (Asterix e Monalisa), com três repetições. Foram avaliados a produtividade, a massa seca, teores de amido, açúcares redutores e açúca… Show more
“…The tuber yield of potato (Solanum tuberosum L.) has increased considerably over the past decades (Faostat, 2015) due to improvements in management practices (Fernandes and Soratto, 2012a) and use of more productive cultivars (ABBA, 2010). Balanced mineral nutrition is essential for high tuber yield and quality (Houghland, 1960;Mesquita et al, 2007;Rosen and Bierman, 2008;Fernandes and Soratto, 2012a). High yield potential, short crop cycle, and high nutrient requirements of potato (Jenkins and Mahmood, 2003;Fernandes et al, 2011) demand nutrients in readily available form in the soil solution.…”

“…No Estado de São Paulo, a recomendação de adubação com micronutrientes inclui apenas o B (Lorenzi et al, 1997), devido ao fato de ter sido constatado que a adição desse micronutriente no solo aumenta a produção de tubérculos graúdos (Gargantini et al, 1970;Boock, 1976;Freire et al, 1981) e diminui os teores de açúcares redutores (Mesquita et al, 2007), melhorando assim a produtividade e a qualidade dos tubérculos. Estudos de adubação com os demais micronutrientes foram conduzidos nas condições brasileiras, no entanto, aumentos expressivos de produtividade foram obtidos apenas com a aplicação de B e Mo (Gargantini et al, 1970(Gargantini et al, , 1986.…”
quantidade de micronutrientes extraída e exportada pela batateira variou com as cultivares utilizadas, indicando necessidade de manejo diferencial da adubação. Atlantic (50, 81, 1,960, 544, Cu, Fe, Mn, and Zn, respectively
“…In relation to the effect of B on chemical quality of fruits Mesquita et al (2007) detach that adequate B nutrition reduces phenolic compounds levels, reduces enzymatic discoloration and significantly increases ascorbic concentration. Therefore, B presents key importance for fruit maturation since it is precursor of ascorbate, which is necessary for ACC oxidase enzyme activity, as proposed by Liu and Yang (2000).…”
-Adequate fertilizing management is crucial to reach high mango yields that demand a well-defined fertilizer management, including micronutrient such as boron which management is more difficult due to the narrow range between deficiency and toxicity. This way, an experiment was carried out to evaluate the fruit production and quality of mango cv. Palmer as a function of boron fertilizing management in Brazilian semiarid. The experimental design was in randomized blocks with six treatments (strategies for boron fertilizing), as follows: T1 = five sprays with H 3 BO 3 (two first at 0.3% and three at 0.2%); T2 = five sprays with H 3 BO 3 (two first at 0.3% and three at 0.4%); T3 = five sprays with H 3 BO 3 (two first at 0.3% and three at 0.6%); T4 = two sprays with H 3 BO 3 at 0.3% + three fertigations with 10 g of H 3 BO 3 plant -1 ; T5 = two sprays with H 3 BO 3 at 0.3% + three fertigations with 20 g of H 3 BO 3 plant -1; and T6 = two sprays with H 3 BO 3 at 0.3% + three fertigations with 40 g of H 3 BO 3 plant -1 . Boron fertilizing management (foliar spray and fertigation) affects fruit production and quality of mango cv. 'Palmer' grown in semiarid. According to the minimum quality criteria required for mango fruit commercialization and the fruit production per plant in semiarid, five sprays with H 3 BO 3 [two first at 0.3% and three at 0.2%] could be recommended.
