As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...

Lasting, effective solutions to nitrogen (N) loss from container nurseries must
address layers of complexity ranging in scale from whole system nursery management
to gene expression. Group-based On-site Active Learning (GOAL) was developed to
aid nursery managers and related stakeholders (e.g. neighbors, policy makers,
regulating agencies, researchers) in developing a...
Five boron rates and seven water levels were applied
to bush green beans (Phaseolus vulqaris cv Oregon 91G) and
to cauliflower (Brassica olereacea var. botrytis, cultivar
"Snowball Y") in 1989 and 1990 to evaluate their effects on
total yield of both crops and on outer quality, head
hollowness and internal...
Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...
