This publication covers crop choices and agronomic aspects of silage production in Florida, from planting until preparing to harvest, for corn. Written by Marcelo Wallau, Joao Vendramini, Adegbola Adesogan, Diwakar Vyas, and Kevin Korus, and published by the UF/IFAS Agronomy Department, revised February 2022.

In the domain of agriculture, the application of optical sensing technology has become increasingly prevalent in the assessment of corn grain production. However, it is notable that comprehensive research endeavors addressing the efficacy of employing the Normalized Difference Vegetation Index (NDVI) as a predictive tool for corn grain yield in the specific context of Florida remain limited. To address this gap in knowledge, a dedicated study focusing on nitrogen (N) rates was meticulously designed in 2022. The primary objective of this study was to provide critical insights and empirical evidence to both our Extension agents and the community of corn farmers. Its overarching aim is to elucidate the practical utility of NDVI sensors in forecasting crop output and facilitating precise estimations of N requirements.

The publication focuses on nitrogen (N) requirements for corn production using best management practices (BMPs) in Florida. The intended audience is corn producers, agricultural consultants, Extension agents, Extension specialists, and researchers. The aim is to provide and recommend BMPs that comply with statewide BMP guidelines, maximizing the yield and economic return while minimizing environmental N losses. The guidelines present results from multi-year, multi-site, field-based research conducted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The small plot research was conducted at the UF/IFAS North Florida Research and Education Center, Suwannee Valley, Live Oak, Florida (NFREC-SV). The publication includes a recommendation in terms of N required per bushel of productivity.
