Abstract Soybean and maize are some of the main drivers Brazilian agribusiness. However, biotic abiotic factors great concern, causing huge grain yield quality losses. Phosphorus (P) deficiency is important among because most soils have a highly P-fixing nature. Thus, large amounts phosphate fertilizers regularly applied to overcome rapid precipitation P. Searching for alternatives improve use P by crops essential reduce demand input. The multifunctional rhizobacteria can be considered one...

Additionally, we evaluated potential Lactobacillus spp. mixture as an approach mitigate damage induced by challenge. One-day-old broiler chickens (n = 252) were divided into seven treatment groups: Control, DON, CP, CP + VL (DON viable mixture), HIL...

Statistical analysis is central to agricultural research, but the complexity of statistical methodologies and programming languages, such as R, often poses challenges for researchers. To address these difficulties, we present AgroR, a comprehensive R package Shiny web application (https://uel.br/fisher.uel.br/AgroR_shiny) designed streamline experiments. AgroR supports wide range experimental designs, offering tools variance, multiple comparison tests, assumption validation, well functions...

Regression analysis is highly relevant to agricultural sciences since many of the factors studied are quantitative. Researchers have generally used polynomial models explain their experimental results, mainly because much existing software perform this and a lack knowledge other models. On hand, natural phenomena do not present such behavior; nevertheless, use non-linear costly requires advanced language programming as R. Thus, work presents several regression found in scientific studies,...
