“…Although it is not considered a nutrient for the soil, silicon is classified as beneficial for plants (Molina Jr., 2017) and can provide greater rigidity to plant cells, in addition to controlling pests and increasing the productivity and/or quality of crops. (Cassel et al, 2021). According to Bakhat et al (2018), soluble Si in the cytosol releases metabolic pathways that cause the production of jasmonic acid, increasing plant defenses against insects, fungi and bacteria.…”

The increasing world population boosted the demand for basic needs such as energy, water, and food. In turn, agricultural production has increased, generating a large amount of agro-industrial waste every year. Globally, Brazil is the seventh-largest rice producer, and the State of Rio Grande do Sul is responsible for 70% of the rice production in Brazil. Rice husks are composed of organic compounds (cellulose, hemicellulose, lignin, and extractives) and inorganic elements that include potassium, calcium, magnesium, and sulfur. These inorganic elements are essential nutrients in the soil. Since natural degradation is slow due to the aromaticity of lignin, rice husk (RH) waste accumulates and poses an environmental threat, causing air and water pollution. In this context, in order to return the biochar to the soil, the properties of rice husk and rice husk biochar were evaluated. Parameters such as pH, true density, bulk density, porosity, identification of the composition and concentration of the elements, analysis of the functional groups, total carbon (TC), and cation exchange capacity (CEC) were performed on RH biochar samples. These samples were produced in a laboratory-scale pyrolysis rig, under a con-trolled atmosphere of Nitrogen (N), using three peak temperatures (350 °C, 450 °C, and 550 °C) and three soak times (30, 60, and 120 min).Based on the results obtained in the characterization analyses of the biochar, as well as the yield values found, it is concluded that the best pyrolysis temperature for the production of biochar from rice husks, for application in soils, is 550 °C.

Silicon (Si) is considered a non-essential micronutrient for vegetables, although it has important functions during vegetative development in some large crops of agricultural interest. This study aimed to evaluate the action of Silicon on vegetative development in a sunflower cultivar ‘Multissol’. The experiment was carried out in full sun in February 2024, with five dosages (0; 150; 300; 600 and 900 kg ha-1) using potassium silicate as a source of Si. The vigor variables for humidity, germination, accelerated aging, weight of 100 grains, electrical conductivity, cold test and emergence in sand and soil were analyzed. Vegetative parameters for plant height, root size, number of leaves, aerial and root fresh mass and aerial and root dry mass were also evaluated. The germination rate was greater than 90%, the electrical conductivity was 100 µS cm-1.g-1, emergence in sand and soil was greater than 90%, regarding the variables of the vegetative phase, there were substantial gains (p < 0.05) in all parameters analyzed, especially for the highest dosage of 900 kg ha-1 when compared between the control. Si has a positive effect on the evaluated parameters and is a non-essential element that has positive effects on sunflower crops, especially on the Multissol cultivar.
