Evaluation of integrated nutrient diagnosis techniques to enhance productivity and quality in greenhouse rose crops
Generate information on integrated nutrient diagnostic technique
This project intends to generate information on integrated nutrient diagnostic techniques, like DRIS, as tools to enhance fertilizer use efficiency, and predict and correct nutritional imbalances that are affecting rose crop flower productivity and quality. The first part (in progress) deals with the theoretical generation & validation of these norms from currently existing datasets on leaf tissue nutrient status and productivity data, to be followed later by their experimental validation in a commercial rose crop. An additional companion study will evaluate the usefulness of expressing tissue nutrient concentrations on leaf area units compared to the conventional leaf dry mass, and how effective are their relationships (correlations) with flower yield and quality.
