Environmental effects on sugarcane growth from on-farm data in the Brazilian Midwest

Climate and soil water availability are factors that influence the growth yield of sugarcane. These can also serve as valuable indicators for predicting maturity biometric changes in sugarcane, enhanced productivity. The aim this study was to determine sucrose accumulation responses surgarcane a function agrometeorological data storage. conducted Santo Antônio de Goiás, Brazil. CTC-4 sugarcane variety assessed across harvests 2013/2014 (cane plant), 2014/2015 (ratoon 1), 2015/2016 2). Agrometeorological were collected from weather station, calculate degree days (DD), potential evapotranspiration (PETP), storage (SWS). Parameters including height (H), leaf area index (LAI), dry matter (DM), number nodes (Nn), soluble solids content (°Brix) measured bi-weekly. Growth rates exhibited decline when SWS below threshold (191.61 mm). highest confidence indices (c>0.85) determined H, Nn °Brix estimates, PET SWS. However, these equations recommended estimate under climate conditions South-Central Predicting variables through models proves valuable, enabling crop monitoring reducing determination costs. Key words: Saccharum spp., variables, analysis, Brazilian Cerrado climate.
