Traditional agricultural research and extension relies on replicated field experiments, on-farm trials, and demonstration plots to evaluate and adapt agronomic technologies that aim to increase productivity, reduce risk, and protect the environment for a given biophysical and socio-economic context. To date, these efforts lack a generic and robust spatial framework for ex-ante assessment that: (i) provides strategic insight to guide decisions about the number and location of testing sites, (ii) define the target domain for scaling-out a given technology or technology package, and (iii) estimate potential impact from widespread adoption of the technology(ies) being evaluated. In this study, we developed …

Broomcorn millet (Panicum miliaceum L.) is the most water-efficient cereal and one of the earliest domesticated plants. Here we report its high-quality, chromosome-scale genome assembly using a combination of short-read sequencing, single-molecule real-time sequencing, Hi-C, and a high-density genetic map. Phylogenetic analyses reveal two sets of homologous chromosomes that may have merged ~5.6 million years ago, both of which exhibit strong synteny with other grass species. Broomcorn millet contains 55,930 proteincoding genes and 339 microRNA genes. We find Paniceae-specific expansion in several subfamilies of the BTB (broad complex/tramtrack/bric-a-brac) subunit of ubiquitin E3 ligases, suggesting enhanced regulation of protein dynamics …


Applicability Of The Dual Isotopes Δ15n And Δ18o To Identify Nitrate In Groundwater Beneath Irrigated Cropland, R. F. Spalding, A. J. Hirsh, M. E. Exner, N. A. Little, K. L. Kloppenborg Jan 2019

Applicability Of The Dual Isotopes Δ15n And Δ18o To Identify Nitrate In Groundwater Beneath Irrigated Cropland, R. F. Spalding, A. J. Hirsh, M. E. Exner, N. A. Little, K. L. Kloppenborg

Department of Agronomy and Horticulture: Faculty Publications

Identification of the nitrate sources that adversely impact groundwater quality is a necessary first step in the control of this major worldwide pollutant. The impact of nitrate leachate from urea-ammonium nitrate (UAN) (50% urea-N, 25% ammonium-N, 25% nitrate-N) fertilizer, whose use has increased dramatically in the last three decades largely because it can be applied through sprinkler irrigation systems to corn in all growth stages, is investigated. The dual isotopes δ15NNO3 and δ18ONO3 were measured in groundwater samples from 39 irrigation wells in two intensively sprinkler-irrigated, corn-growing areas of Nebraska with nitrate-contaminated (N …


Restoring Fire-Grazer Interactions To Pursue Heterogeneity In Sandhills Prairie, Jack R. Arterburn, Dirac L. Twidwell Jr, Carissa L. Wonkka, Walter H. Schacht, David A. Wedin Jan 2019

Restoring Fire-Grazer Interactions To Pursue Heterogeneity In Sandhills Prairie, Jack R. Arterburn, Dirac L. Twidwell Jr, Carissa L. Wonkka, Walter H. Schacht, David A. Wedin

Department of Agronomy and Horticulture: Faculty Publications

Heterogeneity has emerged as a fundamental principle for grassland management and the importance of environmental heterogeneity for biological diversity has raised questions about the appropriateness of grassland practices that seek to promote uniform grassland structure and composition. Principles of uniformity in grassland management reflect a utilitarian target of “managing for the middle” by minimizing both overgrazing and underutilization while avoiding or preventing fire and other disturbances that consume aboveground biomass. We evaluated pioneering efforts to restore fire-grazer interactions via patch burning in an effort to increase spatial heterogeneity at the patch scale in the Nebraska Sandhills, a sandy soil, mixed-grass …


Spatial Imaging And Screening For Regime Shifts, Daniel R. Uden, Dirac Twidwell, Craig R. Allen, Matthew O. Jones, David E. Naugle, Jeremy D. Maestas, Brady W. Allred Jan 2019

Spatial Imaging And Screening For Regime Shifts, Daniel R. Uden, Dirac Twidwell, Craig R. Allen, Matthew O. Jones, David E. Naugle, Jeremy D. Maestas, Brady W. Allred

Department of Agronomy and Horticulture: Faculty Publications

Screening is a strategy for detecting undesirable change prior to manifestation of symptoms or adverse effects. Although the well-recognized utility of screening makes it commonplace in medicine, it has yet to be implemented in ecosystem management. Ecosystem management is in an era of diagnosis and treatment of undesirable change, and as a result, remains more reactive than proactive and unable to effectively deal with today’s plethora of non-stationary conditions. In this paper, we introduce spatial imaging-based screening to ecology. We link advancements in spatial resilience theory, data, and technological and computational capabilities and power to detect regime shifts (i.e., vegetation …

Missouri Novelty Melon Trial Results, James Quinn, Ramón Arancibia, David Trinklein Jan 2019

Missouri Novelty Melon Trial Results, James Quinn, Ramón Arancibia, David Trinklein

Midwest Vegetable Trial Reports

Novelty, specialty or personalized melons are generally smaller and different from traditional Midwest watermelons, cantaloupes or muskmelons. Sugar Cube is a successful example. This project by MU Extension was to evaluate four novelty melons on yield, quality and storage, with Sugar Cube as the control. Included in the evaluation were Brilliant (Canary), Honey Orange (crispy flesh Honeydew), Lambkin (Piel De Sapo), and Lilly (small & early Crenshaw). Each has an appearance and taste profile distinctly different from cantaloupe. The results of this project should give confidence to growers interested in novelty melons, especially for Brilliant (Canary type) and Lambkin (Piel …

Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2019, Petrus Langenhoven

Midwest Vegetable Trial Reports

There is huge potential for the production of sweet bell and tapered peppers in high tunnels. However, information regarding appropriate varieties and yield potential in Indiana is lacking. This paper reports on ten colored sweet bell and tapered pepper varieties that were evaluated at the Purdue Student Farm, West Lafayette, Indiana. Top bell pepper varieties include Chesapeake and Flavorburst. Carmen and Escamillo were some of the top tapered pepper performers.

Zucchini Cultivar Evaluation For Production In West-Central Indiana, 2018, Petrus Langenhoven Jan 2019

Zucchini Cultivar Evaluation For Production In West-Central Indiana, 2018, Petrus Langenhoven

Midwest Vegetable Trial Reports

The state of Indiana is not known nationally as a major zucchini producing state. However, small farm operators produce zucchini generally for local farmers markets, restaurants and some retail outlets. Gowers always wants to know which variety is most suitable for their farming location and market. There are a plethora of varieties available that have different fruit types and growth habits. Characteristics like potential yield and disease resistance are always very important considerations for growers. This paper reports on ten zucchini entries (Table 1; Fig. 3-12) that were evaluated at the Throckmorton Purdue Agriculture Center/Meigs Horticulture Facility, Lafayette, Indiana.
