Conventional overhead watering uses excess water to ensure complete coverage of the entire crop to the point of effective saturation of the root medium or substrate. Under certain conditions, up to 75% of the water and fertilizer applied by overhead

irrigation water usage, many studies have been conducted to determine bedding plants’ responses to water deficits using one of two methods: holding the substrate moisture content (SMC) at a constant level or repeatedly drying down from container capacity (CC

Abstract

Responses of bell peppers (Capsicum annuum L.) to inoculation with the vesicular–arbuscular mycorrhizal fungus (VAMF) Glomus aggregatum (Schenck and Smith emend Koske) were examined under greenhouse and field conditions. Inoculation did not affect tissue P concentrations, growth, or yields in “high”-P soil (0.30 mg P/liter of soil solution) in either the greenhouse or field. In “low”-P soil (0.03 mg P/Iiter), inoculation increased tissue P concentrations, plant weights, and fruit yields relative to noninoculated plants. Tissue P concentrations increased more rapidly after transplanting when seedlings were inoculated at seeding than when inoculation was delayed until transplanting. In the field, total fruit yields and final shoot fresh weights also were higher when transplants were inoculated before transplanting. Water stress reduced fruit yields of plants growing in P-deficient soil less if they were inoculated than if they were not inoculated.

floriculture greenhouses and nurseries apply irrigation and fertilization at a high frequency, thus, potentially leading to the contamination of ground and surface water ( Richards and Reed, 2004 ). Reducing volume or frequency of irrigation would not only save

competitive pricing ( Barnes et al., 2014 ). One strategy for increasing profits is to reduce production inputs, such as irrigation water, fertilizer, plant growth regulators (PGR), overhead (i.e., bench space), and labor. Applying liquid fertilizer with each

Retail environments for marketing floriculture crops have a wide range of light levels and temperature. One common characteristic is that irrigation is almost never optimum as a result of untrained personnel or understaffing. Watering practices at
