Unlocking the Potential of Technology: Estimating Nitrogen Requirement in Corn Using Optical Sensors

Lakesh K. Sharma, Diego A. H. de S. Leitão, and Hardeep Singh

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.

Nitrogen Fertilizer Guidelines for Field Corn Production in Florida

Karun Katoch, Michael Dukes, Shivendra Kumar, Jay Capasso, Diego Arruda Huggins de Sá Leitão, Hardeep Singh, and Lakesh K. Sharma

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.
