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.

Differences in Growth, and Nitrogen Uptake and Storage Between Two Container-Grown Cultivars of Rhododendron

The information provided by this study will aid in the development of fertilizer management strategies for container nursery production practices that will decrease fertilizer use and production costs, improve plant quality, while minimizing N losses to the environment.

Nitrogen Foliar Feeding has Advantages

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.

Nutrient Uptake and Distribution in a Mature 'Pinot noir' Vineyard

Report on a study undertaken to investigate nutrient uptake and distribution of mature Vitis vinifera L. 'Pinot noir' vines (23 to 24 years old) grown without irrigation in a region with low summer rainfall common to western Oregon vineyards.

Put Mycorrhizae to use

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

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).

Changes in Polyamine Content and Localization of Pinus sylvestris ADC and Suillus variegatus ODC mRNA transcripts During the Formation of Mycorrhizal Interaction in an In Vitro Cultivation System

Research report detailing a study conducted on the involvement of polyamines (PAs) in the interaction between Pinus sylvestris L. seedlings and an ectomycorrhizal fungus Suillus variegatus (Swatz: Fr.) O. Kunze in an in vitro cultivation system.

Methods of Nitrogen Application in Summer Affects Plant Growth and Nitrogen Uptake in Autumn in Young Fuji/M.26 Apple Trees

The intent of this study was to determine the (1) effect of soil versus foliar nitrogen (N) applications during the summer on tree growth, and (2) effect of soil versus foliar N applications during summer on N uptake in the autumn in young apple trees.

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

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

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.
