Relationship between corn and soybean yields

The relationship between corn and soybean yields on the same land varies from year to year, depending on the weather. Corn/soybean yield ratios express the relative yield of corn to soybean (i.e., 134 bu/acre of corn is 3.05 times greater than 43.5 bu/acre of soybean). Table 1 presents the average Iowa corn and soybean yields, and the corn/soybean yield ratios from 1990 to 2001. These ratios indicate that weather favored corn versus soybean growth and development during some years. The higher the ratio above 3.0:1, the greater the advantage for corn during that year; and the lower the ratio below 3.0:1, the greater the advantage for soybean. These ratios refer to agronomic advantage only and may not have a direct relationship to market value of the crop

What is the best soybean seeding rate

The seeding rate for soybeans varies considerably from producer to producer. The range is from 100,000 to 300,000 seeds per acre. A major seed company recently recommended planting 200,000 to 230,000 seeds per acre. Research at Iowa State University has shown that a lower seeding rate will give top yields

Nurse Educators’ Perceptions of Using High-Fidelity Simulation in Teaching

Nurse Educators’ Perceptions of Using High-Fidelity Simulation in Teaching. Marline Whigham, 2017: Applied Dissertation, Nova Southeastern University, Abraham S. Fischler College of Education. Keywords: nursing education, learning strategies, simulation, staff development, teaching styles. High-fidelity simulation in nursing refers to the use of computerized manikins to offer realistic hands-on training to nursing students. The problem addressed by this dissertation was resistance among some faculty to the use of new computerized simulation technology in the nursing curriculum. The research question for this case study investigated how faculty members can incorporate simulation into the curriculum and barriers faced in setting the stage for simulation experiences for their students. The goal of this applied dissertation study was to examine the perceptions of nurse educators regarding the benefits of and barriers to use of high-fidelity (computerized manikin) simulation with students in a university nursing program. Interviews were used in this qualitative case study to gather perceptions from educators in a university nursing program. The study was based on the qualitative research method with a case study design. The theoretical underpinnings for the study were concentrated within a constructivist framework. Twelve nursing educators were interviewed regarding their perceptions of the use of simulation in the nursing curriculum. The findings indicated that faculty believed the use of simulation to be beneficial to nursing students by increasing patient safety, improving students’ critical thinking, improving learning outcomes, and increasing competency to transfer to clinical practice. Faculty recommended further training and technical support to maximize effective use of simulation

Recommended Practices for Soybean Management

Soybean production depends on numerous environmental variables including rainfall, sunshine, day length, and temperature. They also depend on soils and soil characteristics, which provide nutrients and other inputs to the plants. There are also numerous factors that are controllable, such as: variety selection, tillage, planting date, row spacing, plant population, and nutrients. All of these factors influence where and when soybeans are produced and the regions of the world that produce more soybean than other regions

Soybean Management for Increased Yield

Soybeans have become an extremely important feed, food and industrial crop in the world and the number two crop of importance in Iowa. World production during 1996 has the US as the largest soybean producer with 48%, followed by Brazil (20% ), China ( 10% ), Argentina ( 10% ), and Paraguay (2%). The remaining 10% come from many other countries. The Midwest dominates production within the US where seven states produced 71% of the 1996 soybean crop. Iowa was the leading US producer with 17.5% (416 million Bu.) of the total production, followed by Illinois (16.7%), Minnesota (9.4%), Indiana (8.5%), Ohio (6.6%), Missouri (6.3%), and Nebraska (5 .6%). The 1997 soybean production estimates have Iowa and Illinois as the Number I and 2 leading states again. In Iowa, the average yield per acre for 1997 is estimated to be above the 1996 state average (44 Bu/A), but less than the record yield produced in 1994 (50.5 Bu/A). Weather variability across the state resulted in a wide range of reported yields this harvest season. Some producers were pleased with their yields and others were disappointed. The total soybean production will likely be high this year because of the increased acreage planted in 1997 compared to recent years. Higher yields and more acres harvested will contribute to the nationwide record production, which is estimated to be more than 2.7 billion bushels. The Iowa Soybean Promotion Board supported the following soybean management research with funds from the soybean checkoff program. The author is grateful for this continued research support

Plant soybeans before mid-May

Research results from five stations in Iowa show that producers must plant soybeans by mid-May to achieve maximum yields. Soil conditions must be ready for planting or compaction will affect plant growth throughout the season. Delayed planting may result in additional penalties due to weather interference and serious yield potential may be lost

Filling the Absence: the re-embodiment of sites of mass atrocity and the practices they generate

Despite the particularities that are present within every instance of genocide or state terror, one thing they all share is that, once the physical violence ends, there are always sites that are left behind, many of which contain material reminders or even concrete evidence of the violations that occurred within their boundaries. By focusing specifically on la Escuela Mecánica de la Armada (ESMA), the largest former concentration camp in Argentina, this article examines these sites as places that allow for a certain set of shared, embodied practices to be performed both by the curators or organizers of the sites, as well as the visitors to the sites. I argue that it is never the spaces themselves, but rather the practices that transpire within these spaces and through the process of transforming the space from a site of atrocity into a site of memory that influence the constructive processing of past violence. They do so through their ability to make people re-encounter and re-activate the past in the present
