Mungbean [Vigna radiata (L.) Wilczek] is a short-duration and relatively drought-tolerant crop grown predominantly in the tropics. This grain legume can improve soil fertility through biological nitrogen (N) fixation. To assess the effects of Bradyrhizobium (group I) inoculation on yield and yield attributes of mungbean, a greenhouse study was conducted during Fall 2016 with two mungbean cultivars (‘Berken’ and ‘OK2000’), two inoculum treatments (inoculated and uninoculated), and two soil textur...

ABSTRACTIn corn (Zea mays L.) production, determining appropriate nitrogen (N) rates is a critical part of achieving profitable yields, while minimizing negative environmental effects. Many tools to assist in the determination of optimum corn sidedress N rates exist, however, those that are low cost, that can be used in real time and that do not require extensive scouting or sampling may be preferred. This study compared the rates prescribed by four in-season N rate recommendation approaches: (1...

Canopy spectral reflectance (CSR) is a cost-effective, rapid, and non-destructive remote sensing and selection tool that can be employed in high throughput plant phenotypic studies. The objectives of the current study were to evaluate the predictive potential of vegetative indices as a high-throughput phenotyping tool for nitrogen use efficiency in soft red winter wheat (SRWW) (Triticum aestivum L.) and determine the optimum growth stage for employing CSR. A panel of 281 regionally developed SRW...
