In addition to essential macronutrients and micronutrients, bioregulators, biostimulants or bioactivators are being increasingly used on agricultural crops with important outcomes. Therefore, improved knowledge on the functioning of these chemicals on plants is needed. Based on the assumption that foliar fertilizers applied at specific times promote soybean growth, development and yield, the aim of the present study was to evaluate the biometric, biomass, physiological, nutritional and grain yield parameters to increase knowledge about specific fertilizers applied alone or in combination and at different stages of soybean growth and development. The present study was performed in partnership between the Goiano Federal Institute (Instituto Federal Goiano), Campus Rio Verde, state of Goiás (GO), Brazil, and the company Tecno Nutricao Vegetal e Biotecnologia Ltda. A randomized block experimental design was used with four replicates. The biometric, physiological, nutritional and yield data were subjected to analysis of variance followed by Tukey’s test when significant differences were found at p 0.05 using the SISVAR software. In the emergency and early use of Tonik combined with Nodumax and PreventCoMo, in the vegetative phase, the Lumix combined with Vivat or VivatMn in the reproductive stage of flowering, 2 application Tripper combined with VivatB at a dose of 500 ml·ha-1 and reproductive phase of grain filling, 2 application Apport at a dose of 500 g·ha-1 gave the best results.

The aim of this work was to evaluate the effects of the application of different sources and doses of nitrogen(N)in the growth and productivity of sugarcane in cane *** experiments were conducted in the area of Rio Paraiso II farm,belonging to the Raízen factory,in the city of Jataí,*** soil was classified as dystrophic red *** experimental design used was in randomized block,analysed in factorial scheme of 2×4×4,with three *** factors analysed were two sources of N(urea and ammonium nitrate),four doses of N(0,60,120 and 180 kg/ha)and four evaluation times(210,250,290 and 330 d after planting(DAP)).The parameters analysed were plant height(PH),diameter of stalks(DS),length of internodes(LI)and productivity of stalks(PS).Results observed significant difference in the sources and doses of N for the evaluated parameters in sugarcane *** in the average doses of 110 kg/ha and 100.87 kg/ha provided the greatest PH and LI of sugarcane,*** nitrate at a dose of 180 kg/ha presented the largest DS of sugarcane(cane plant)at 330 *** PS of sugarcane SP80-1816 at 60 kg/ha and 120 kg/ha ammonium nitrate has higher *** the PS,it is recommended the application of doses between 60 kg/ha and 120 kg/ha of N of the source ammonium nitrate in sugar cane(cane plant).

Monkeypox:A looming concern for children?

Several countries around the world have followed the growing number of monkeypox(MPX) cases with concern, as they are still very sensitive to fears of a new tragic pandemic, as was the case with COVID-19. This alarm has been prolonged since May 2022[1,2], when the current outbreaks of the disease were observed in several countries outside the area normally associated with the circulation of the causative virus, monkeypox virus(MPXV).
