Objetivou-se avaliar o desenvolvimento de Urochloa ruziziensis submetida a inoculação, via sementes, com diferentes bactérias promotoras crescimento vegetal modo suprir parte da sua exigência nutricional e ajudar no cultivo sustentável dessa forrageira. O ensaio foi conduzido em vasos polietileno substrato solo corrigido, realizado DIC (Delineamento Inteiramente Casualizado) 7 tratamentos onde (T1) controle (sem inoculação); (T2): inoculação Burkholderia cepacia; (T3): Herbaspirillum frisingense; (T4): Pseudomonas stutzeri; (T5): Rhizobium cellulosilyticum; (T6): Sphinghomonas sp.; (T7): Stenotrophomonas maltophilia. Cada tratamento teve 6 repetições cada repetição foram conduzidas 3 plantas os resultados obtidos partir média aritmética dessas. Com duração 79 dias, avaliados: número perfilhos, matéria fresca aérea radicular, seca total total. Foi feito então análise variância teste Scheffé para se houve incremento significativo na produtividade relação ao sem inoculação. Os apresentados discutidos baseados estatística descritiva, por meio média erro padrão média. Dentre as avaliadas, frisingense incrementou aproximadamente 17% 11% ruziziensis, tornando-se uma estirpe selecionada novos estudos.

Pasture degradation poses significant economic, social, and environmental impacts in the Brazilian savanna ecosystem. Despite these impacts, effectively detecting varying intensities of agronomic biological through remote sensing remains challenging. This study explores potential eight-band PlanetScope SuperDove satellite constellation to discriminate between five classes pasture degradation: non-degraded (NDP); pastures with low- (LID) moderate-intensity (MID); severe (SAD); (SBD). Using a set 259 cloud-free images acquired 2022 across sites located central Brazil, aims to: (i) identify most suitable period for discriminating various classes; (ii) evaluate Random Forest (RF) classification performance different attributes; (iii) compare metrics accuracy derived from two predicted scenarios more challenging one involving (NDP, LID, MID, SAD, SBD), another considering only severely degraded SBD). The assessed individual combined sets attributes, including band reflectance, vegetation indices, endmember fractions spectral mixture analysis (SMA), image texture variables Gray-level Co-occurrence Matrix (GLCM). results highlighted effectiveness transition rainy dry season towards beginning new seasonal cycle October degradation. In comparison season, favorable discrimination were observed during season. increased amounts non-photosynthetic (NPV) complicate differentiation NDP SBD, which is characterized by high soil exposure. Pastures exhibiting showed greater sensitivity water stress, manifesting earlier reflectance changes visible near-infrared bands compared other classes. Reflectance-based yielded higher overall (OA) than approaches using fractions, or metrics. Classifications attributes achieved an OA 0.69 0.88 five-class three-class scenarios, respectively. scenario, highest F1-scores (0.61) (0.71) (0.88) degradation, indicating challenges separating low moderate stages An initial RF categories pastures, utilizing data MultiSpectral Instrument (MSI)/Sentinel-2 (400–2500 nm) (400–900 nm), demonstrated enhanced (0.79 versus 0.66) Sentinel-2 data. enhancement likely be attributed inclusion shortwave infrared (SWIR) analysis.

Cultural diversity often complicates the understanding of sustainability, sometimes making its concepts seem vague. This issue is particularly evident in food systems, which rely on both renewable and nonrenewable resources drive significant environmental changes. The widespread impacts climate change, aggravated by overuse natural resources, have highlighted urgency balancing production with preservation. Society faces a pivotal challenge: ensuring that systems produce ample, accessible, nutritious while also reducing their carbon footprint protecting ecosystems. Agriculture 5.0, an innovative approach, combines digital advancements sustainability principles. study reviews current knowledge agriculture, analyzing scientific data through undirected bipartite network links journals author keywords from articles retrieved Clarivate Web Science. main goal to outline framework integrates various concepts, emphasizing well-studied (economic) underexplored (socioenvironmental) aspects 5.0. categorizes into material (tangible) immaterial (intangible) values based supporting or influencing roles within agriculture domain, as documented literature.
