Title

Greywater as a Viable Alternative for Irrigation of 10 Fall-planted Spring-flowering Geophytes Forced for Early Spring Flowering

Maren E. Veatch-Blohm; Ellen Roussel; Eliana Marzullo; et al. HortScience 2023. doi:10.21273/hortsci17247-23

Other claims from this paper (8)

Intervention effect Greywater generally did not affect biomass, nutrient profile, or visual quality.
Intervention effect Greywater reduced fresh biomass of Allium.
Intervention effect Greywater reduced fresh biomass of Hyacinthus.
Intervention effect Greywater had no impact on dry biomass or visual quality for the affected genera.
Intervention effect Greywater had no negative impacts on survival, flower number, or flower duration.
Intervention effect Greywater delayed Narcissus Dutch Master flowering by an average of 7 days in year one.
Intervention effect Greywater delayed Tulipa Parade flowering by an average of 6 days in year one.
Recommendation The authors consider greywater a viable irrigation alternative for container-grown spring-flowering geophytes.
