ABSTRACT Many guidelines for agronomic management of peanut (Arachis hypogaea L.) are well-established when considered individually. However, crop productivity is typically driven by more than one variable and the interactions of multiple practices are not as easily derived. With an ever-changing availability of new cultivars with greater disease resistance, improved yield and/or grade potential, and varying growth characteristics, there is a steady need for agronomic research in both the immediate and distant futures. In some cases, traditional agronomic experimentation on variables such as rotations, tillage and land management, timing of planting, row pattern and spacing, seeding rate, irrigation, plant growth regulators, inoculant/biological products and fertilization need to be revisited every several years when a new cultivar becomes commercially relevant. This is especially true with differing climates and soil types in various growing regions. The effects of climate and weather along with pest pressure, pest management programs, and maturity characteristics of cultivars are also drawing the attention of peanut agronomists to improve predictability of optimum maturity. Yet, peanut agronomists are also attempting to adapt new ideas to assist with management decisions and increase revenue potential for growers to stay competitive in a very volatile commodity market domestically and with fluctuating export opportunities. The adoption of technologies such as GPS guidance, seed monitors, aerial imagery, and variable rate planting or spraying equipment are becoming more common to assist growers with better precision in planting and digging practices, ensuring proper seed placement, and assessing problematic areas in the field for site-specific in-season management decisions. So many excellent achievements have been made through the collaborations of scientists of the American Peanut Research and Education Society over the last 50 years, and there is no doubt that similar collaborations remain strong throughout the current membership to lead us into the future.

ABSTRACT To commemorate the 50th anniversary of the American Peanut Research and Education Society (APRES) we examined the changes in average yields of peanut (Arachis hypogaea L.) during that time period. Before APRES, yields had never been greater than 2242 kg/ha (2,000 lb/ac). In 1967 the average yield was 1978 kg/ha (1967 lb/ac). In 2017 the average peanut yield was 4566 kg/ha (4074 lb/ac). Average yield gains for the first 50 years of APRES was 51.8 kg/ha/yr (46.2 lb/ac/yr). APRES played critical roles in facilitating research and extension to achieve these yield advances for the U.S. peanut industry.

Russian thistle (Salsola tragus L.) is a persistent post-harvest issue in the Pacific Northwest (PNW). Farmers need more integrated management strategies to control it. Russian thistle emergence, mortality, plant biomass, seed production, and crop yield were evaluated in spring wheat and spring barley planted in 18- or 36-cm row spacing and seeded at 73 or 140 kg ha−1 in Pendleton and Moro, Oregon, during 2018 and 2019. Russian thistle emergence was lower and mortality was higher in spring barley than in spring wheat. However, little to no effect of row spacing or seeding rate was observed on Russian thistle emergence or mortality. Russian thistle seed production and plant biomass followed crop productivity; higher crop yield produced higher Russian thistle biomass and seed production and lower crop yield produced lower weed biomass and seed production. Crop yield with Russian thistle pressure was improved in 2018 with 18-cm rows or by seeding at 140 kg ha−1 while no effect was observed in 2019. Increasing seeding rates or planting spring crops in narrow rows may be effective at increasing yield in low rainfall years of the PNW, such as in 2018. No effect may be observed in years with higher rainfall than normal, such as in 2019.

AbstractWhere do new ideas come from and how are they generated? Which of these ideas will be potentially useful immediately, and which will be more ‘blue sky’? For the latter, their significance may not be known for a number of years, perhaps even generations. The progress of computing and digital media is a relevant and useful case study in this respect. Which visions of the future in the early days of computing have stood the test of time, and which have vanished without trace? Can this be used as guide for current and future areas of research and development? If one Internet year is equivalent to seven calendar years, are virtual worlds being utilized as an effective accelerator for these new ideas and their implementation and evaluation? The nature of digital media and its constituent parts such as electronic devices, sensors, images, audio, games, web pages, social media, e-books, and Internet of Things, provides a diverse environment which can be viewed as a testbed for current and future ideas. Individual disciplines utilise virtual worlds in different ways. As collaboration is often involved in such research environments, does the technology make these collaborations effective? Have the limits of disciplinary approaches been reached? The importance of interdisciplinary collaborations for the future is proposed and evaluated. The current enablers for progressing interdisciplinary collaborations are presented. The possibility for a new Renaissance between technology and the arts is discussed.

Terminal Guidance

Successful interception of manoeuvring anti-surface missiles that are expected in the future can be achieved only if the estimation errors against manoeuvring targets can be minimized. The paper raises new ideas for an improved estimation concept by separating the tasks of the estimation system and by explicit use of the time-to-go in the process. The outcome of the new approach is illustrated by results of Monte Carlo simulations in generic interception scenarios. The results indicate that if an eventual ‘jump’ in the commanded target acceleration is detected sufficiently rapidly, small estimation errors and consequently precise guidance can be obtained.

The Impact

Abstract One of the major challenges in agriculture is how climate change influences crop production, for different environmental (soil type, topography, groundwater depth, etc.) and agronomic management conditions. Through systems modelling, this study aims to quantify the impact of future climate on yield risk of winter wheat for two common soil types of Eastern Denmark. The agro-ecosystem model DAISY was used to simulate arable, conventional cropping systems (CSs) and the study focused on the three main management factors: cropping sequence, usage of catch crops and cereal straw management. For the case region of Eastern Denmark, the future yield risk of wheat does not necessarily increase under climate change mainly due to lower water stress in the projections; rather, it depends on appropriate management and each CS design. Major management factors affecting the yield risk of wheat were N supply and the amount of organic material added during rotations. If a CS is characterized by straw removal and no catch crop within the rotation, an increased wheat yield risk must be expected in the future. In contrast, more favourable CSs, including catch crops and straw incorporation, maintain their capacity and result in a decreasing yield risk over time. Higher soil organic matter content, higher net nitrogen mineralization rate and higher soil organic nitrogen content were the main underlying causes for these positive effects. Furthermore, the simulation results showed better N recycling and reduced nitrate leaching for the more favourable CSs, which provide benefits for environment-friendly and sustainable crop production.

New System

This chapter discusses the analytical contrast between the two systems for organizing research and education, the system of academic professionalism and the system of academic innovationism. Under the impetus of academic innovationism, universities became more porous to the outside world and reciprocal relations of knowledge exchange grew denser. On balance, the new system contributed significantly and positively to the research prowess of universities. But it has also yielded a spotty record—some extraordinary successes but also many short-lived, troubled collaborations. Some universities invested heavily in the infrastructure to foster academic innovation and had little to show for their investments. For research universities, the challenge for the future will be to expand the possibilities to contribute more to the national innovation effort.

And Performance

This chapter illustrates the twelve-step process known as the Circle of Societal Death. Assume some externally caused source of economic decline. This will lower governmental functioning by lowering tax revenues. Low government revenues and performance demoralize government functionaries. When government officials are powerless and irrelevant, there is no reason for them not to become corrupt; corruption in the police and the judiciary leads to crime. Once people become genuinely worried about personal security, networks of social cooperation contract. This means they delegitimize everything outside the group, especially the state, and everything becomes defined in ethnic terms. As both crime and ethnic conflict escalate, young people are drawn into self-defense activity. The movement of youth from investment in the future to coercion in the present mortgages the economic growth of the future. As youth are pulled out of education, society becomes less intellectually capable. Fundamental engineering, business, and technological skills become lost, and projects of large-scale coordination suffer. As projects of large-scale coordination become nonviable, economic growth declines. This circle of death also works in reverse.
