E. SMITH, 1797) (lepidoptera: noctuidae) Autor(es): Fleuri, Fabyane Almeida Primeiro Orientador: Nogueira, Luciano Abstract: Cotton cultivation has high economic importance in Brazil and is frequently affected by insect pests that compromise productivity, especially the fall armyworm, Spodoptera frugiperda, due to its high damage potential and wide adaptive capacity. This study aimed to evaluate the efficacy of cotton biotechnologies against Spodoptera frugiperda in the western region of Bahia. The bioassays were conducted at Instituto Federal Goiano – Campus Posse, under laboratory conditions, using both field and susceptible reference populations. Newly hatched larvae up to 24 hours old were exposed to leaves and bolls of Bacillus thuringiensis cotton and conventional cotton. Larval survival and mortality were evaluated throughout the exposure period, resulting in high efficiency of the transgenic cultivars, with a progressive increase in larval mortality over time. It is concluded that the evaluated technologies are effective in controlling the pest, contributing to the reduction of crop damage; however, the adoption of resistance management strategies, combined with continuous population monitoring, is essential to ensure the durability of these technologies and the sustainability of the production system Editor: Instituto Federal Goiano Tipo: Trabalho de Conclusão de Curso 2026-03-27T00:00:00Z https://repositorio.ifgoiano.edu.br/handle/prefix/6438 Título: NANOTECNOLOGIA APLICADA À SOJA: POTENCIAL FUNCIONAL DE NANOPARTÍCULAS DE ÓXIDO DE ZINCO (ZnO) E FERRO (Fe₂O₃) - UMA REVISÃO DE ESCOPO Autor(es): Lima, Josiel Ferreira Primeiro Orientador: Costa, Alan Carlos da Abstract: The application of nanoparticles in agriculture has been investigated as a strategy to optimize nutritional efficiency and mitigate stress in economically important crops. In soybean (Glycine max L.), zinc oxide (ZnO) and iron oxide (Fe₂O₃) nanoparticles have been associated with both beneficial effects and phytotoxic responses, depending on experimental conditions. This study consisted of a scoping review, conducted according to the Joanna Briggs Institute guidelines and reported following the PRISMA-ScR checklist, with a protocol registered on the Open Science Framework (DOI 10.17605/OSF.IO/BYDSJ). The search was performed in Web of Science, Scopus, and the Brazilian Digital Library of Theses and Dissertations (BDTD), resulting in 275 records, of which 29 studies fully met the eligibility criteria based on the PCC strategy. The analysis showed that the effects of nanoparticles are predominantly dose dependent. At low to moderate concentrations, increases in biomass, photosynthetic activity, modulation of the antioxidant system, and productivity gains were observed. In contrast, high doses were associated with oxidative stress, reduction of photosynthetic pigments, impairment of biological nitrogen fixation, and reproductive damage. The transition between adaptive response and phytotoxicity was mainly conditioned by dose, application route, and physicochemical properties of the nanoparticles. Based on the findings, integrated criteria are proposed to differentiate nutritional effects from stress-inducing effects, contributing to a more consistent interpretation of the literature and to the rational use of these nanomaterials in soybean cultivation.

Seed coating is an important technique in the forage seed production process, a technology aimed at improving physical quality, facilitating sowing, and adding commercial value to seeds. This study aimed to evaluate different materials used for coating seeds of two forage cultivars (Urochloa brizantha cv. Marandu and Urochloa brizantha × Urochloa ruziziensis cv. Convert 330), considering physical and visual aspects, dissolution, seedling emergence, and cost. The experiment was conducted at the Seed Technology Laboratory of Barenbrug do Brasil, in a 2 × 6 factorial design with three replications, consisting of two cultivars and six mixtures of inert coating materials: attapulgite + dolomite, bentonite, bentonite + dolomite, dolomite, wheat flour + dolomite, and sweet potato starch + dolomite. The following were evaluated: incrustation factor, particle size sieving, visual score, color, water dissolution, seedling emergence, and cost. The dolomite-based treatments showed better physical uniformity, higher visual score, and better color. Bentonite, alone or in combination with dolomite, provided high dissolution and good physical performance. The treatments containing isolated dolomite showed low dissolution, resulting in lower seedling emergence. It can be concluded that the choice of inert material directly influences the physical and physiological quality of coated seeds, with mixtures containing bentonite and dolomite being the most balanced in terms of quality and performance Editor: Instituto Federal Goiano Tipo: Trabalho de Conclusão de Curso 2026-02-27T00:00:00Z https://repositorio.ifgoiano.edu.br/handle/prefix/6396 Título: EFEITO DOS MICRORGANISMOS EFICIENTES NO DESENVOLVIMENTO DA ALFACE (Lactuca sativa L.) Autor(es): Siqueira, Izabella Aparecida de Campos Primeiro Orientador: Golinski, Janete Primeiro Membro da Banca: Golinski, Janete Segundo Membro da Banca: Golynski, Anselmo Afonso Terceiro Membro da Banca: Basilio, Ênio Eduardo Abstract: Lactuca sativa is one of the most cultivated and consumed leafy vegetables in Brazil, standing out for its high nutritional value and wide market acceptance. However, conventional cultivation requires intensive use of chemical fertilizers, which may cause environmental impacts and increase production costs. In this context, the use of effective microorganisms (EM) emerges as a sustainable alternative, promoting improvements in soil fertility and plant development. The present study aimed to evaluate the effect of applying effective microorganisms on the growth of lettuce. The experiment was conducted at the Instituto Federal Goiano – Campus Morrinhos in a completely randomized design, with four treatments and four replications. The treatments consisted of: T1 (control, without application), T2 (one application), T3 (two applications), and T4 (three EM applications). The variables evaluated were plant height, number of marketable leaves, number of damaged leaves, fresh mass, and shoot dry mass. Data were subjected to analysis of variance, and means were compared using Tukey’s test at 5% probability. The results showed no statistically significant differences for most of the analyzed variables. However, a significant effect was observed for the number of marketable leaves, with emphasis on the treatment with one EM application. It is concluded that the application of effective microorganisms positively influenced an important qualitative attribute of the crop, although it did not significantly increase overall productivity.
