Mental Model-Based Repeated Multifaceted (Mrm) Intervention Design: A Conceptual Framework For Improving Preventive Health Behaviors And Outcomes, Mazbahul G. Ahamad, Fahian Tanin

Department of Agronomy and Horticulture: Faculty Publications

Objective: Field interventions employed to improve preventive health behaviors and outcomes generally use well established approaches; however, recent studies have reported that health education and promotional interventions have little to no impact on health behaviors, especially in low- and middle-income countries. We aimed to develop a conceptual framework to improve intervention designs that would internalize these concerns and limitations.

Results: We identified three major experimental design- and implementation-related concerns associated with mental models, including the balance between the treatment and control groups, the treatment group’s willingness to adopt suggested behaviors, and the type, length, frequency, intensity, and sequence of treatments. …

What Does Past Research Tell Us About Alfalfa Drying Rates?, Jordyn Bush

Kentucky Alfalfa and Stored Forage Conference

Today I’m going to give everyone a brief overview of a literature review I’ve been working on at the request of a local farmer. While writing this literature review, I looked at the factors that influence how quickly alfalfa dries down. I also read past research that has been conducted in an attempt to predict when hay will be dry or how long it will take to do so. The ultimate goal of this literature review was to determine the feasibility of creating some sort of hay drying prediction or forecasting system for Kentucky.

Measuring Forage Quality: Sampling And Interpretation, Christopher D. Teutsch

Kentucky Alfalfa and Stored Forage Conference

Forage quality is often described with terms like crude protein, neutral detergent fiber, acid detergent fiber, in vitro dry matter digestibility, neutral detergent fiber digestibility, and the list goes on! Perhaps the best definition of forage quality is the ability of a forage to produce a desired animal response. This concept is quite simple, but the process of getting from forage to actual animal performance is quite complex (Figure 1). It is important to realize that there is no perfect measure of forage quality. However, measures that are based on fiber digestibly provide better estimates of energy and dry matter …

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr, Meredith M. Guthrie

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Cultivating Hops For Cone Production In Nebraska, Stacy A. Adams

Department of Agronomy and Horticulture: Faculty Publications

The hop cone is the primary product of agronomic value when growing Humulus lupulus L. (common hop). Cones are modified stem and leaf structures that protect the female flower cluster that forms chemical compounds important for flavoring beer and other uses. The majority of hops in the United States (~96%) is grown in the states of Washington, Oregon, and Idaho. Hops can be grown in very diverse climates, but it is the climatic consistency of the Pacific NW that provides product consistency and reasoning commercial hops production is prevalent in the region. Hops is a niche crop outside of the …
