“…A similar trend in pear trees was reported by Wang et al (2011), who obtained a significant decrease of 37.60% as they increased the dose of B applied hydroponically, taking as control the dose of 10 ppm and increasing it up to 500 ppm. These results can be explained by the findings of Flores et al (2018), which indicate that an increase in B fertilization has no effect on nitrogen metabolism, which is strongly related to chlorophyll content.

Boron (B) nanofertilizers are an innovative alternative with great potential to make nutrient application more efficient and thereby improve crop growth and productivity. However, nowadays there is little literature on the effects of boron nanofertilizers on physiological and biochemical processes in plants. Therefore, the objective of the present research was to study the efficacy of foliar application of a boron nanofertilizer on biomass, yield, nitrogen assimilation and photosynthetic activity in green beans plants cv. Strike. The B nanofertilizer was foliar applied at 0, 25, 50 and 100 ppm. Biomass accumulation, yield, nitrate reductase enzyme activity, photosynthetic activity, stomatal conductance and photosynthetic pigment content were evaluated. The results obtained indicate that the application of B nanofertilizer at dose of 25 ppm were more effective in improving biomass, while the dose of 100 ppm favoured nitrate reductase activity and stomatal conductance. The results suggest that the application of B nanofertilizers stimulated the development of green bean plants. Finally, more studies are needed to evaluate the possible phytotoxic effects of high doses of B nanofertilizers and to compare their effects with conventional B fertilizers already used in the market.

“…The variations in the effects for the chlorophyll content in the plants of soil fertilization treatments with varied doses of micronutrient (adopting B as reference) revealed that the supply of up to 4.0 kg ha -1 of the micronutrient did not affect the chlorophyll index at 28 and 46 days after emergence (Flores et al 2018a), the fertilization with 4.39 kg ha -1 promoted a higher chlorophyll index at 40 days after germination (Flores et al 2017), while doses up 6.0 kg ha -1 reduced pigment rates in common bean leaves (Flores et al 2018b).…”

Micronutrient fertilization is essential to meet the nutritional deficiency of plants, providing the full development of crops. The aim of this work was to evaluate the effects of fertilization with micronutrients applied in the soil on the nutrition and morphology of soybean plants. The experimental design was completely randomized, with four replications. The treatments consisted of fertilization with micronutrients applied to soil to reach three levels of availability of B: low (<0.15 mg dm-3-control), good (0.61 mg dm-3) and high (> 0.90 mg dm-3). For this, the following values were applied: 0.00 (control), 56.67 and 211.11 kg ha-1 of the fertilizer containing 1.8% B, 0.85% Cu, 2% Mn and 9% Zn. Fertilization with the good and high treatments did not affect the uptake of B, but increased the Cu and Mn content, and reduced the Zn content in the plants. Higher plants with greater leaf expansion were observed in the high treatment, however, this did not influence the soybean grain yield. In the control, the physiological activity revealed smaller A, whereas gs and Ci were more effective; reverse effect was observed with high treatment. Fertilization with micronutrients in the soil affects the nutritional status and the photosynthetic activity of the plants due to the imbalance in the concentrations of B, Cu, Mn and Zn supplied with the fertilizer, reflecting in the absence of gains in the production of soybean grains. Highlighted Conclusions 1. Fertilization with micronutrients in the soil using as criterion the reach of three levels of availability of B does not increase the production of biomass and grains, despite ensuring foliar contents of B (Ȳ= 40.40) and Cu (Ȳ= 23.06) suitable for soybean cultivation in the Cerrado. 2. The inequity in the concentrations of B, Cu, Mn and Zn supplied with fertilizer affects the physiological performance of soybean plants.

“…Contudo as plantas deficientes em boro apresentam aumento na atividade da RNAase, que é uma enzima responsável por hidrolisar o RNA e possuem menor síntese de uracila a partir do ácido orótico. Visto que o boro participa do metabolismo do RNA e está relacionado a síntese do uracil, que é considerado como um dos componentes do RNA (FLORES et al, 2018b).…”

“…Quando utilizado em concentrações elevadas o boro pode inibir o crescimento das plantas (ALI et al, 2013). Flores et al (2018b), verificaram que a cultivar de feijão Esplendor demonstrou elevada capacidade de absorção de boro, podendo atingir até 175 mg kg-¹. Porém os níveis elevados de absorção do elemento, ocasionaram fitotoxicidade e reduziram a produção da matéria seca em torno de 30%.…”

A cultura do feijão em nosso país além de participar de maneira expressiva no cenário econômico que engloba a cadeia do agronegócio, exerce uma função cultural bastante intensificada por ser um dos símbolos básicos da alimentação da população e importante fonte de proteína. O Brasil destaca-se no ranking mundial como um dos principais países produtores e consumidores de feijão (Phaseolus vulgares L). Esta cultura pode ter sua produtividade limitada pelo baixo teor de Boro (B) encontrada em parte dos solos brasileiros cultivados, onde os níveis adequados deste nutriente varia de 1,0 a 1,2 mg dm-3. Com isso, pode existir a necessidade de se fazer a adubação para superar a limitação na produtividade por deficiência de Boro no solo e na planta. As plantas absorvem B na forma de ácido bórico. Ao longo dos anos o nível tecnológico empregado na produção do feijão vêm aumentando significativamente, neste sentido diversas pesquisas tem sido direcionadas para práticas de manejo que gerem rentabilidade e produtividade dessa cultura. Essa revisão tem por objetivo discorrer sobre a relevância da adubação bórica na cultura do feijoeiro e identificar em quais estádios de desenvolvimento essa adubação seria crucial para o ciclo da planta, assim como levantar a resposta à adubação bórica das principais variáveis agronômicas estudadas.
