“…Studies with foliar fertilization of micronutrients in soybean crop are reported in the literature: application of foliar fertilizer together with herbicides increased the grain mass (Moraes et al, 2017), increase in the number of pods per plant and grain mass. In addition, studies demonstrate positive effects of foliar fertilization on the performance of other crops such as cassava (Bester et al, 2020), beans (Ferreira et al, 2021), oats (Silva et al, 2019), corn (Ferreira et al, 2021), soybean (Frota et al, 2020) and Physalis peruviana (Pedó et al, 2018).…”

The use of foliar fertilizers has become the main innovation in the field of plant mineral nutrition. And the use of these micronutrients associated with multivariate tools can contribute to the technical development of agribusiness, especially in soybean. Therefore, the aim of this study was to verify the possible correlations between morpho-agronomic characters of soybean supplemented via leaf with micronutrients. The study was conducted under field conditions in the county of Mineiros, GO, Brazil. The experimental design used was in randomized blocks in a 3x5 factorial scheme corresponding to three soybean genotypes (Anta82, CD2737 and N7902) and five concentrations of leaf supplement, Triplus Anuais® with its guarantees of phosphorus 2%, boron 3.4%, molybdenum 1% and 0.35% nickel. The leaf supplement was applied in a single dose during pre-flowering (0, 300, 600, 900 and 1200 ml ha-1). The highest yield potential was observed in the NS 7209 IPRO genotype at doses of 300 and 600 ml of leaf supplementation via Triplus Anuais. In addition, field adjustments to increase the averages of pods with two grains, grains per plant and mainly pods per plant, can increase the yield of genotypes.

“…Soybean is one of the main crops of agriculture, with a relevant socioeconomic role, with Brazil being the second largest world producer of oilseeds. In the 2018/2019 harvest, the crop occupied an area of 35.8 million hectares in the country, with a 1.9% increase in planted area compared to the previous harvest, with an estimated production of 114.4 million tons of grains (Companhia Nacional de Abastecimento [CONAB], 2019;Hanyu, Costa, Cecon, & Matsuo, 2020;Soares, Sediyama, & Matsuo, 2020;Ferreira et al, 2020;Frota et al, 2020;Carvalho et al, 2021).…”

The cultivation of soybeans is the main agricultural commodity in Brazil, the increase in the cultivated area in recent years and the productivity of grains is interconnected with numerous factors such as sowing time, water availability, temperature and photoperiod. The objective of this work was to evaluate the duration of phenological sub-periods and the productivity of soybean cultivars from different groups of relative maturation, sown in two seasons in the off-season in the northwest region of the State of Rio Grande do Sul (RS). The experiment was carried out at Agropecuária Bubans geographically located in the county of Ijuí in the state of RS, considered medium locality. The experiment was carried out using a randomized block design with four replications, the experimental units consisted of four lines, four meters long, 0.50 m apart. The treatments were eight soybean cultivars with different groups of relative maturity (4.8, 5.8, 5.9, 6.2, 6.3, 6.4, 6.7 and 7.8) sown on January 5 and 22, 2019 (from agricultural zoning, the preferred season for sowing in this region is from october to december), constituting an 8 x 2 factorial experiment (Cultivars x sowing times). Assessments of the duration of phenological sub-periods and of the yield components of the culture were carried out, being measured with total plant height, first pod insertion height, number of lateral branches, number of reproductive nodes on the main stem, total number of nodes on the main stem, number of pods with one, two, three and four grains, pods mass of one, two, three and four grains, total grain mass per plant, thousand seed mass and grain yield. The most productive relative maturity group is 6.3 being sown in the first non-preferential season for soybeans in Rio Grande do Sul. The second sowing time changed the dynamics of association of the measured variables, with changes in the cycle, reductions in the vegetative and reproductive period.

Fertilization with nanoparticles offers alternatives to improve the efficiency of nutrient absorption in a sustainable way in crops. The objective of this work was to study the influence of foliar application of zinc-molybdenum nanofertilizer (Nano ZnMo) on nitrogen (N) use efficiency (NUE), as well as on yield parameters and N assimilation in green bean plants cv. “Strike”. Three doses of Nano ZnMo (0, 4 and 8 ppm) were applied foliar in combination with four doses of N in the form of NH4NO3 in nutrient solution (0, 3, 6 and 12 mM). The treatment that obtained the greatest increase in total biomass was the combination of 6 mM N + 4 ppm Nano ZnMo, with an increase of 11.6% compared to the treatment without application of Nano ZnMo. The treatment that registered the highest yield was the combination of 3 mM of N + 4 ppm of Nano ZnMo with an increase of 39.3% compared to the treatment without foliar application of Nano ZnMo (3 mM of N). The utilization coefficients (NUtE) and NUE were favored with the foliar application of Nano ZnMo at 4 ppm in combination with 3 and 6 mM of N in nutrient solution. These treatments made it possible to reduce the dose of N fertilization without compromising production. Therefore, the foliar adhesion of Nano ZnMo makes it possible to improve the efficiency of nutrient absorption and sustainably increase crop productivity.
