Soil amelioration via strategic deep tillage is occasionally utilized within conservation tillage systems to alleviate soil constraints, but its impact on weed seed burial and subsequent growth within the agronomic system is poorly understood. This study assessed the effects of different strategic deep-tillage practices, including soil loosening (deep ripping), soil mixing (rotary spading), or soil inversion (moldboard plow), on weed seed burial and subsequent weed growth, compared with a no-till control. The tillage practices were applied in 2019 at Yerecoin and Darkan, WA, and data on weed seed burial and growth were collected during the following 3-yr winter crop rotation (2019 to 2021). Soil inversion buried 89% of rigid ryegrass (Lolium rigidum Gaudin) and ripgut brome (Bromus diandrus Roth) seeds to a depth of 10 to 20 cm at both sites, while soil loosening and mixing left between 31% and 91% of the seeds in the top 0 to 10 cm of soil, with broad variation between sites. Few seeds were buried beyond 20 cm despite tillage working depths exceeding 30 cm at both sites. Soil inversion reduced the density of L. rigidum to <1 plant m−2 for 3 yr after strategic tillage. Bromus diandrus density was initially reduced to 0 to 1 plant m−2 by soil inversion, but increased to 4 plants m−2 at Yerecoin in 2020 and 147 plants at Darkan in 2021. Soil loosening or mixing did not consistently decrease weed density. The field data were used to parameterize a model that predicted weed density following strategic tillage with greater accuracy for soil inversion than for loosening or mixing. The findings provide important insights into the effects of strategic deep tillage on weed management in conservational agricultural systems and demonstrate the potential of models for optimizing weed management strategies.

This study introduces Health Technology Assessment (HTA) — a systematic, evidence-based, multidisciplinary approach to assessing human health technologies, aimed at supporting decision-making in health policy and clinical practice — into laboratory animal science. A conceptual presentation is provided on how the assessment concept of HTA can be adapted to procedures in laboratory animal science (LAS), using phenotyping of mutant mice as an example of how decision-making in this particular setting can be supported. Since a full HTA can be a comprehensive task, a limited version, the Mini-HTA, is introduced, and a proposal for an adapted Mini-HTA form of assessment of phenotyping protocols is presented. It is the conclusion of this study that the principles of HTA could improve the decision-making process, resulting in increased validity of scientific results and animal welfare.

Maize is the primary staple crop cultivated during the monsoon season in eastern India. However, yield gaps are large because of multiple factors, including low adoption rates of good agronomic management practices. This study aimed to narrow the maize yield gap using diverse agronomic and varietal interventions through field experiments over 2 years (2013–2014) in the rainfed plateau region of Odisha. As a result, maize yield increased by 0.9, 0.74, and 0.17 Mg ha−1 under optimum plant population, fertilizer management, and herbicide-based weed management, respectively, over farmers’ current practices (Check). Moreover, when all three interventions were combined (‘best’ management practice), grain yields increased by 1.7 Mg ha−1 in conservation tillage and 2.2 Mg ha−1 in conventional tillage. We also observed that the combination of long-duration hybrids and best management practices (BMPs) increased grain yield by 4.0 Mg ha−1 and profitability by $888 ha−1 over farmers’ current practices. In addition, Nutrient Expert decision support tool-based fertilizer management along with BMPs increased grain yield by 1.7 Mg ha−1 and profitability by $314 ha−1 over farmers’ fertilizer practices (Check). These results suggest that the combination of maize hybrids and BMPs can improve the productivity and profitability of rainfed maize in the plateau region of Odisha. However, these entry points for intensification need to be placed in the context of varying investment requirements, input and output market conditions, and matched with farmer preferences and risk.

As time-to-market is getting shorter, customer needs have to be identified as early as possible in product development. Correctly applied, corporate foresight can give a glimpse into the future to anticipate such needs and thus gain a competitive advantage. A support tool to choose the appropriate method of foresight is not available yet. Thus, a literature study on foresight methods in industry is performed and a novel decision support tool is proposed which avoids high entrepreneurial risks. Based on the findings, potentials for future work are identified for different types of methods.

Aflatoxin is a fungal toxin contaminating corn and causing liver cancer in humans and animals. Contamination is driven by high temperatures and drought. Aflatoxin assessment is expensive so extension services need to identify high risk areas so irrigation, planting strategies and corn varieties can be adapted. This research presents a web-based decision support tool for risk illustrated with a case study from southern Georgia. The tool employs the approach, developed by Kerry et al. (2017b) where exceedance of key thresholds in temperatures, rainfall, soil type and corn production are used to determine risk. The tool also includes NDVI to indicate drought stress and could be further expanded to include new risk factors and adapted to other crops.

Objectives: The purpose of this project was to evaluate local decision support tools used in the Danish hospital sector from a theoretical and an empirical point of view.

Methods: The use of local decision support was evaluated through questionnaires sent to all county health directors, all hospital managers, and all heads of clinical departments in cardiology, orthopedic surgery, and intensive care. In addition, respondents were asked to submit whatever decision support tools they were using (including mini-HTAs, other forms or checklists, and special procedures for decision making concerning new health technologies). A theoretical analysis of the decision support tools (decision theory) was performed as well as a comparison with the business case method used in private companies. Finally, the Danish mini-HTA was compared with foreign production and use of HTA and HTA-like assessments as local decision support.

Results: The response rate was high (87 percent, 94 percent, 85 percent, respectively). We collected sixty different forms (of which forty-nine were mini-HTAs) and twenty variants of written procedures. We found theoretical and empirical evidence that local involvement in the process of making the HTA could be important for the use of the results from the HTA and for the process of implementing the new technology.

Conclusions: Doing mini-HTA in hospitals seems to balance the need for quality and depth with the limited time and resources for assessment.
