Energy-Use-Efficiency Differences Between LED Supplemental Lights under Nutrient Film Technique (NFT) and Constant Flood Table (CFT) Systems- Alex Miller, Krishna Nemali, Petrus Langenhoven

Using energy efficient light emitting diodes (LED) and heated nutrient solution (21°C) (HNS) in suboptimal greenhouse air temperatures (16°C), electrical energy use efficiency (EUE) (g·KWh-1) can be optimized to reduce production costs. Our objective was to compare EUE differences between nutrient film technique (NFT) and constant flood table (CFT) systems under LED lighting treatments with

A Novel Smartphone-based Technology for Measuring Nitrogen (N) Status in Floriculture Crops- Ranjeeta Adhikari1, Cheng Li2 and Krishna Nemali1*

Optimal tissue nitrogen (N) is crucial for growth and quality of plants. Currently, laboratory analysis is the only direct method available to accurately measure tissue N. However, this method is time-consuming. Other equipment like chlorophyll meter are expensive. The objective of this study is to develop affordable and non-destructive technology for measuring N status of
