Sustainable agriculture describes crop management approaches that address the interdependent goals of increasing or at least maintaining yield while protecting the environment, conserving natural resources, and slowing climate change. Numerous authors have espoused limiting synthetic fertilizer and pesticides and promoting organic agriculture (Lechenet et al., 2014; Martinez-Alcantara et al., 2016; Muller at al. 2017), less meat consumption (West et al., 2014; Poore and Nemecek, 2018; Springmann et al., 2018), or combinations of these strategies as viable solutions to achieve those goals, thereby improving agricultural sustainability.


Canavalia And Dolichos Extracts For Sustainable Pest Biocontrol And Plant Nutrition Improvement In El Salvador, Carlos Martinez 2019 University of Nebraska - Lincoln

Canavalia And Dolichos Extracts For Sustainable Pest Biocontrol And Plant Nutrition Improvement In El Salvador, Carlos Martinez

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Botanical repellents and pesticides are now being rediscovered as new tools for integrated pest management in order to reduce the use of toxic chemicals in crop production. Canavalia gladiata and Dolichos lablab are two Fabaceae very well adapted to farmlands of El Salvador, effective as living barriers and mostly as cover crops, however, they are not yet very well disseminated. This document describes the potential for using the liquid extracts and the dry flour of raw seeds of those plants for economic benefit and practical convenience for pest management in Salvadorian agriculture under field conditions. Seed extracts were useful when ...

Molecular Phylogeny Implemented In An Introductory Plant Classification Course, Chao Cai, Jo Ann Banks 2019 Purdue University

Molecular Phylogeny Implemented In An Introductory Plant Classification Course, Chao Cai, Jo Ann Banks

Libraries Faculty and Staff Presentations

Plant classification is one of the core components in undergraduate programs related to plant sciences. Traditionally plant classification courses primarily introduce morphology-based taxonomy because of practical needs in the field. However, the publication of new plant classification systems by Angiosperm Phylogeny Group (APG) using molecular phylogeny methods leads to the trends of using molecular evidence (DNA barcode) for plant identification. In our introductory plant classification course, we included a two-week module (lectures and labs) to introduce key concepts and fundamental skills in molecular phylogeny. Week 1 included concepts of evolutionary tree thinking, data mining in NCBI using BLAST search, and ...

The Capacity Building Workshops on Nature-Culture Linkages in Heritage Conservation (CBWNCL), held at the University of Tsukuba in Japan, gather Asia-Pacific heritage professionals with the aim of creating a platform of mutual-learning and exchange between the culture and nature sectors. In the first workshop on Agricultural Landscapes, from 14 case studies, 5 showed natural protected areas in tense relations with their rural landscape surroundings. However, these agricultural landscapes are essential for protecting natural values, as they form part of their larger ecosystems. In the second workshop on Sacred Landscapes, from 16 case studies, 5 case studies were also agricultural landscapes ...


Volatile Prices And Profi T Margins, Chad Hart, Lee L. Schulz 2019 Iowa State University

Volatile Prices And Profi T Margins, Chad Hart, Lee L. Schulz

Lee Schulz

THE CALENDAR year 2019 has been interesting for agricultural markets. We began the year with record supplies for all of Iowa’s major commodities. However, trade disputes have cast a cloud over growth in crop and livestock usage and weather events and foreign disease outbreaks have sparked quick reversals in commodity prices. Since the first of the year, corn prices have fluctuated by $1.10 per bushel, soybeans by $1.55 per bushel, hogs by $28 per hundredweight, and cattle by $16 per hundredweight. And we’re still only halfway through the year.

Beaver And Aspen : Synergy Among Keystone Species, Stephen Bennett, Nicolaas Bouwes, Paul C. Rogers

Nicolaas Bouwes

In the West, climate change is likely to increase the frequency, intensity, and duration of drought. Restoration of soils and water storage capacity can help create resilient uplands and riverscapes (i.e., streams and the valley bottoms). Over the past two centuries, common land uses, the removal of beaver and wood, straightening of streams, and damage to riparian areas have created simplified, structurally starved, riverscapes. Degraded streams are very efficient at transporting water, sediment, and nutrients downstream. Aspen forests are also biological hotspots that have been degraded by past land uses such as overbrowsing ungulates, land clearing, fire suppression, and ...

Capacity And Distribution Of Water Stored In The Vadose Zone Of The Chinese Loess Plateau, Yuanjun Zhu, Xiaoxu Jia, Jiangbo Qiao, Andrew Binley, Robert Horton, Wei Hu, Yunqiang Wang, Ming’An Shao

Agronomy Publications

Water stored in the vadose (unsaturated) zone provides the majority of water required by plants and buffers water resources; thus, it is central to understanding ecological and hydrological processes in the Chinese Loess Plateau (CLP) with its thick loess deposits. We used multisource data on soil water content (SWC) and vadose zone thickness, combined with a spatial interpolation method, to quantify the vadose zone water and further deduce the water resource composition in the CLP. Vadose zone water is approximately 3.1 × 1012 m3 (±27.5%) in the CLP, 92.4% of which is stored in the deep ...

Nitrogen Requirements Of Ethiopian Mustard For Biofuel Feedstock In South Dakota, Phillip Alberti, Shannon Osborne, Febina Mathew, Shakaut Ali, Heidi Sieverding, Sandeep Kumar, Thandiwe Nieya

Febina Mathew

Ethiopian mustard (Brassica carinata A. Braun) is a non-food oilseed crop that has received attention for its potential as a low-input biofuel feedstock suitable for production in the semiarid regions of the Northern Great Plains (NGP). Because B. carinata is a new crop to the NGP, the best management practices have yet to be developed. The objective of the study was to evaluate the effects of N fertilizer rate on seed yield, seed oil concentration, and oil yield of B. carinata and to determine the economic optimum N fertilizer rates. Field studies were conducted at two locations in South Dakota ...

Most consumers do not understand today’s highly complex global food system. Much of the food production and processing occurs far away from where they live and buy groceries. External environmental and community costs related to the production, processing, storage, and transportation of the food are seldom accounted for in the food’s price, nor are consumers made aware of these external costs. Examples of external environmental costs are the increased amount of fossil fuel used to transport food long distances, and the increase in greenhouse gas emissions resulting from the burning of these fuels.

Rust fungi are devastating pathogens for several important crop plants. The biotrophic lifestyle of rust fungi requires that they influence their host plants to create a favorable environment for growth and reproduction. Rust fungi secrete a variety of effector proteins that manipulate host target proteins to alter plant metabolism and suppress defense responses. Because of the obligate biotrophic lifestyle of rust fungi, direct evidence for effector function is difficult to obtain, and so suites of experiments utilizing expression in heterologous systems are necessary. Here, we present results from a yeast cell death suppression assay and assays for suppression of PAMP-triggered ...
