Expand the adoption of precision plant based irrigation technologies to reduce water use in both greenhouse and nursery product

Evaluation of a modified version of the CropAssist system developed for greenhouse tomatoes on other ornamental plants. Two greenhouse species and two nursery species, each of which differed in daily water requirements, were monitored for periods of up to 30 consecutive days. Results indicated that the CropAssist system effectively measured water uptake automatically and continuously.

Water treatment technologies

A literature review was conducted and interviews with growers and water treatment companies to assemble information on available technologies. An interactive website will provide growers with an on-line decision process for choosing appropriate technology for their own operation.

Biocontrol strategy for the control of aphids on greenhouse ornamentals

a strategy to use Botanigard in combination with natural enemies for control of aphids in greenhouse floriculture. This research has enhanced the general understanding of how parasitoids used for biological control of aphids in ornamental systems interact with Botanigard. It has also identified some critical knowledge gaps and opportunities for future technology development.

Winter greenhouse heat consumption reduction

Researchers have found that significant energy reductions of up to 20% can be achieved by a combination of reduced night time temperature, morning CO2 injections and ventilation control. The specific combination of these climatic adjustments enables average temperatures to be maintained at the optimal level and produces more vigorous plants that are ready for holiday delivery dates

Dynamic greenhouse climate control to conserve energy and improve crop quality

Conserving energy is a top priority for flower greenhouse operators. With this objective in mind, Dr. Xiuming Hao with Agriculture and Agri-Food Canada developed and assessed greenhouse heating and climate control strategies that would conserve energy without sacrificing timely production and maximum plant quality.
