Resumo: | The boron (B) fertilization in soybean is important to ensure great yields. Boron correction must be applied in deficient soils repairing losses, exports and leaching. The objective of this study was to evaluate the effects of doses, methods and times of application of B in soybean B content and yield. The field experiments were conducted during the 2015/16 and 2016/17 cropping seasons and set as a randomized block design with nine treatments (0, 0.5, 1, 1.5, 2 kg ha-1 of B, 0.5 kg ha-1 of B mixed with NPK (02-28-18) in furrow during sowing, foliar application with 0.3 kg ha-1 of B in V4 soybean stage, foliar application with 0.3 kg ha-1 of B in R1 soybean stage, and foliar application of 0.15 kg ha-1 in V4 plus 0.15 kg ha-1 of B in R1 soybean stage) and four replications. Boric acid was the B source and the variables analyzed were: B leaf content, B exported in seeds, number of pods per plant, number of seeds per pod, weight of 100 seeds (g) and productivity (kg ha-1). The levels of B in leaf were between 30.1 and 43.8 mg kg-1 and between 65.0 and 92.6 mg kg-1 in the 2015/16 and 2016/17 growing season, respectively. Exports of B in seeds were estimated between 166 and 248 g ha-1 and between 208.9 to 260.8 g ha-1 in the 2015/16 and 2016/17 growing season, respectively. Great productivity (3,820 kg ha-1) was observed in the 2016/17 growing season, with an estimated dose of 0.95 kg ha-1 of B. |

O objetivo deste estudo foi avaliar os efeitos de doses, avaliar modos e épocas de aplicação de B na produtividade da soja. Os experimentos foram implantados na Fazenda Experimental da UEG, Campus Ipameri, nas safras 2015/2016 e 2016/2017 com delineamento em blocos ao acaso, com nove tratamentos e quatro repetições. 0,0; 0,5; 1,0; 1,5; 2,0 kg ha-1 de boro, - 0,5 kg ha-1 de B junto com NPK 2-28-18 no sulco de semeadura; aplicação foliar com 0,3 kg ha-1 de boro em V4; aplicação foliar com 0,3 kg ha-1 de boro em R1; aplicação foliar de 0,150 kg ha-1 em V4 mais 0,150 kg ha-1 de boro em R1. Foi utilizado como fonte o ácido bórico. As variáveis respostas analisadas foram: teor na folha, exportação pelos grãos, número de vagens por planta, número de grãos por vagem, massa de 100 grãos e produtividade. Os teores de B encontrados ficaram entre 30,12 e 43,83 mg kg-1 na folha de soja na safra 2015/2016 e entre 65,0 e 92,6 mg kg-1 na safra 2016/2017. As exportações de Boro foram estimadas entre 166 e 248 g ha-1 e 208,9 a 260,8 g ha-1 na primeira e segunda safra, respectivamente.
