Chicoric Acid Levels in Commercial Basil (Ocimum basilicum) and Echinacea purpurea Products

Greenhouse
In this study researchers evaluated the chicoric acid concentrations in dried and fresh basil (Ocimum basilicum) products available to consumers and how these concentrations compare to those from E. purpurea plant and products.

Rate of Nitrogen Application During the Growing Season Alters the Response of Container-Grown Rhododendron and Azalea to Foliar Application of Urea in the Autumn

Nursery Crops
Using deciduous and evergreen cultivars of container-grown Rhododendron, the objectives of this study were to determine: (i) whether N application rate during the growing season influenced plant response to foliar urea application in the Autumn; and (ii) whether plant N status in the Winter influenced plant reliance on fertilizer for growth the following Spring.

Nitrogen Foliar Feeding has Advantages

Fertilizer
An examination of the advantages and affects of nitrogen (N) foliar feeding on the quality of nursery plants. Topics include which N formulation is best, fall applications, advantages of fall foliar nitrogen, and spring applications.

Put Mycorrhizae to use

Soil
A discussion about mycorrhizae, a natural fungi that can greatly improve plants' nutrient and water uptake. The authors specifically discuss why mycorrhizae are important, whether or not they are needed, necessary materials, and when and how to use mycorrhizae.

Phosphorus Supply Alters Tuber Composition, Flower Production, and Mycorrhizal Responsiveness of Container-Grown Hybrid Zandtedeschia

Geophyte
The purpose of this study was to determine if arbuscular mycorrhizal fungi (AMF) inoculation influences plant development, reproduction (vegetative and floral), and/ or tuber quality in calla lily (Zantedeschia spp. and hybrids).

Timing of Urea Application Affects Leaf and Root N Uptake in Young Fuji/M.9 Apple Trees

Fertilizer
The ambitions of the study were to compare the effects of different timings of nitrogen (N) application on leaf and root N uptake, and to determine the distribution of N absorbed by leaves and roots at different times in young Fuji/M.9 apple trees.

Inoculation with Ericoid Mycorrhizal Fungi Alters Fertilizer Use of Highbush Blueberry Cultivars

Fertilizer
This study investigates the potential role EMF plays in container-grown blueberry production. Specifically, it was determined whether growth and nutrition of highbush blueberry is influenced by inoculation with various EMF isolates, and whether the response to EMF is altered by the type of fertilizer used.

Isolate-specific Rooting Responses of Leucothoe fontanesiana Cuttings to Inoculation with Ericoid Mycorrhizal Fungi

Nursery Crops
The intent of the study was to determine whether an EMF inoculum, added to the rooting substrate during cutting propagation, can alter root production by L. fontanesiana, and whether responses to inoculation depend on the EMF isolate used as inoculum.

Inoculation with Vesicular-Arbuscular Mycorrhizal Fungi and Rhizobacteria Alters Nutrient Allocation and Flowering of Harlequin Flower

Bulbs
The objectives of the study were to 1) determine whether addition of AMF inoculum into the growing medium of harlequin flower alters aspects of flower production, bulb production, and bulb quality, and 2) assess whether other rhizosphere organisms present in the AMF inoculum play a role in plant response to inoculation.

Growth and Nutrient Use of Ericaceous Plants Grown in Media Amended with Sphagnum Moss Peat or Coir Dust

Nursery Crops
The objectives of the USDA-ARS affiliated study were to determine whether growth, nutrient use, and storage components of ericaceous plants differ when grown in media amended with varying proportions of sphagnum peat or coir.
