Wheat yield and protein estimation with handheld- and UAV-based reflectance measurements

 Core Ideas

∙ GreenSeeker (GS) and UAV NDVI at Feekes 5 shows the most potential for in-season wheat yield estimation.

∙ Comparable accuracy of yield estimation was achieved with GS NDVI and UAV NDVI.

∙ The accuracy of yield estimation was comparable for all wheat classes and cultivars.

∙ Estimation of in-season wheat protein content remains a challenge.

UI Parma MS student to serve on national Graduate Student Committee

 

Our MS student, Emmanuella Owusu Ansah, a graduate research assistant in the Cropping Systems Agronomy program at UI Parma, has been selected to serve on this committee, and she will also be participating in the Graduate Student Leadership Conference at the tri-societies' annual meeting in Baltimore, MD in November.

Spring wheat yield and grain quality response to nitrogen rate

 Core Ideas

• Application of all N fertilizer at planting is not efficient for wheat.
• Nitrogen fertilizer rates for wheat should account for site- and year-specific conditions.
• When prescribing N rates to wheat, yield potential and responsiveness to N should be considered.
• Higher N rates resulted in enhanced grain protein content, but low N use efficiency.

Mott Award Honors Top Graduate Students

Congratulations to the students who are recipients of this year’s Gerald O. Mott Meritorious Graduate Student Award in Crop Science. This annual award recognizes top-notch graduate students pursuing advanced degrees in crop science disciplines. Departments select students based on academic achievements, research and teaching contributions, leadership accomplishments, service activities, and personal qualifications. Multiple students from one school may be recognized as these students represent their departments.

The award is named for the first CSSA President, Gerald O. Mott, who trained 75 graduate students during his 45-year career at Purdue University and the University of Florida. Many of his students have become eminent forage scientists in the United States and Latin America. The award is offered by CSSA.

Congratulations to Ms. Ritika Lamichhane, MS student, Graduate Research Assistant, Cropping Systems Agronomy program, University of Idaho, Parma R&E Center for receiving this prestigious award!

Top Downloaded Manuscript: Seeding rate and nitrogen fertilizer rate effect on dryland no-till hard red spring wheat yield and quality

 Core Ideas

• Nitrogen rate significantly affected wheat grain yield, protein content, protein yield, and N uptake at both locations, and N use efficiency at one of two locations.
• The 135 and 67 kg ha−1 pure live seed seeding rates resulted in comparable grain yield, test weight, grain protein, protein yield, and N uptake.
• Wheat protein yield was highest at 140 kg N ha−1; higher N rate (especially split-applied) may have improved wheat production further.

No inverse yield–protein relationship was observed at any of two locations.

Economic Impacts of Climate Change on Agriculture in Idaho

The agricultural sector comprises an important part of the Idaho economy, with agriculture and
food and beverage processing accounting for over 18% of total business sales (Idaho State
Department of Agriculture (ISDA), 2020). Conditions in the sector influence the lives of all
Idahoans to at least some degree through provision of food that fuels daily activities. The goal of this report is to describe the economic risks and opportunities for the Idaho agricultural sector in the context of climate change. The report describes current conditions in the Idaho agricultural sector, observed changes in Idaho’s climate and trends in agricultural productivity over the past several decades, projected changes in Idaho’s climate and agricultural productivity for key subsectors, specific effects of the changing climate on key agricultural subsectors as identified in the peer-reviewed research literature, the important linkages between water availability and agricultural sector performance, and existing evidence of adaptation strategy adoption by Idaho farmers.
Given the uncertainty regarding future conditions for the climate, environmental resource policy, agricultural markets, demographics, and general macroeconomic conditions, a numerical estimation of economy-wide variables was not calculated. However, the report provides stakeholders essential information that characterizes the linkages between climate and agricultural production and the risks and opportunities based on their location, current climate conditions, and projections for future climate and water availability. Additionally, many
plausible adaptation strategies that Idaho farmers and ranchers may adopt in response to future changes in climate are provided. Such insights can be used by policymakers and stakeholders to consider potential impacts on their own institutions and businesses and plan appropriate responses. The interactions between adjustments in grower practices in the context of climate change, and especially the effects of such shifts on water availability, will be key to explaining the performance of the Idaho agricultural sector in the decades ahead. 

Wheat Characteristics under Varied Irrigation and Nitrogen

 

• A strong positive correlation was observed between grain yield and irrigation but not with the N rate. The results suggest that irrigation can be reduced by 25% (medium irrigation) while crops maintain optimal grain yield and grain protein content. This recommendation will help to reduce water usage by 25% during wheat production in semiarid cropping systems.
• Application of 150 kg N ha-1 (soil residual N plus added fertilizer) is sufficient to optimize the grain yield and protein content of irrigated spring wheat grown in Idaho and Montana. This rate is lower than the currently recommended N rate in each state. Therefore, this recommendation will minimize input costs during wheat production, environmental impacts, and human health concerns.
• Strong positive correlations of SPAD or NDVI with grain yield suggest the feasibility of using these crop sensors for in-season wheat yield assessment, especially in irrigated cropping systems.
