“…Debnath et al (2011) found a higher yield of wheat grain at a dose of 1.9 kg ha -1 B. However, Brunes et al (2015) verified that boron fertilization, applied at sowing or tillering in doses between 2.5 and 3.0 kg ha -1 caused an increase in the number of seeds and spikes per plant, but with a reduction of seed yield per plant, mass of 1000 seeds and the hectoliter mass, unlike the one verified in the present work. However, a drastic reduction of grain yield was observed above the dose of 2.8 kg ha -1 of B.…”

Boron is one of the most limiting micronutrients in the grain production system in Brazil, mainly due to its complex dynamics in the soil-plant system. In this way, the objective of this study was to evaluate the efficiency of application forms and doses of boron with emphasis on wheat grain yield. The experiment was conducted in no-tillage system in an Oxisol with clay texture in Selvíria, MS. The experimental design was a randomized block design with four replicates arranged in a 4 x 3 factorial scheme, using four doses of boron (0, 1, 2 and 4 kg ha-1) with boric acid source (B = 17%); and three apllication forms: (A1) in desiccation of the predecessor straw, along with herbicide; (A2) at the time of sowing, in soil along with the formulated fertilization seeding and (A3) foliar application along with the syrup of the herbicide (with the application of post emergent herbicide). The increase in boron doses reduced the recovery of apparent boron (RAB), boron uptake efficiency (BUpE) and agronomic efficiency (AE), but the application of 2 kg ha-1 provided the highest boron utilization efficiency (BUtE) and wheat grain yield. We recommend application of 2 kg ha-1 of B in the soil at sowing to obtain approximately 4311 kg ha-1 of wheat.

“…These results may be explained mainly by the low B requirement of the used corn hybrid, besides the high soil clay content, which could increase the adsorption of this element. Trautmann et al (2014) also did not find B influence on soybean grain yield, although other reports highlight the importance of B on reproductive development of crops (DEBNATH et al, 2011;MUHMOOD et al, 2014;BRUNES et al, 2015). Yet, Adiloglu and Adiloglu (2006) verified that shoot dry matter yield of corn plants grown in Zn-deficient soil decreased with B application, while increased with Zn application soil.…”

Brazilian Cerrado soils are commonly deficient in boron (B) and zinc (Zn). It is still debated whether B and Zn interaction has a synergistic or antagonistic effect on the absorption thereof. Thus, we conducted this study to evaluate the effect of boron rates (0, 1, 2, 3, and 4 kg ha?1, as boric acid), with or without zinc fertilization (2 kg ha?1 Zn, as zinc sulfate), on corn nutritional status and grain yield. We also assessed the residual effect of such fertilization on the fall corn crop grown on an Oxisol in a no-tillage system. A synergistic effect between B and Zn was observed on corn nutritional status when applied to the soil at rates of up to 2 kg ha?1, with higher soil contents resulting from the interaction between these micronutrients. Zinc fertilization and increasing boron rates had no significant influence on corn grain yield in both spring/summer and fall crops, grown on a boron-deficient, clayey soil of Cerrado biome.

“…Muhmood et al (2014) researched the borate fertilization of wheat and obtained a higher grain yield at a dose of 2 kg ha -1 and Debnath et al (2011) found a higher yield of wheat grain at a B dose of 1.9 kg ha -1 . However, Brunes et al (2015) found that borated fertilization applied at sowing or tillering in doses between 2.5 and 3.0 kg ha -1 caused an increase in the number of seeds and spikes produced per plant. However, there was a reduction in the seed yield per plant, the mass of 1000 seeds, and the hectoliter mass.…”

Boron is one of the most limiting micronutrients in the grain production system in Brazil. Thus, the objective of this study was to evaluate the effects of the application forms and doses of boron on the concentration of this nutrient in the leaves, straw, and grains of wheat, as well as the production components and grain yield. The residual effect of boron in the soil was also evaluated. An experiment was conducted in a no-tillage system in Oxisol with clay texture in Selvíria, Mato Grosso do Sul. The experimental design was a randomized block design with four replicates arranged in a 4 x 3 factorial scheme. Four doses of boron (0, 1, 2, and 4 kg ha-1) were applied with a boric acid source (B = 17%) and three application forms: a) during the desiccation of the predecessor straw with herbicide; b) at the time of sowing in soil along with formulated fertilization seeding, and c) via the leaves with the application of post-emergent herbicide. The application of boron to the soil at the time of sowing at an approximate dose of 2 kg ha-1 provides the highest number of spikelets per ear and wheat grain yield.
