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
