Wheat Variety-Specific Grain Yield Response To Plant Density Under Intensive Management Conditions In Western Kansas, R. P. Lollato, K. Mark, B. R. Jaenisch
Wheat Variety-Specific Grain Yield Response To Plant Density Under Intensive Management Conditions In Western Kansas, R. P. Lollato, K. Mark, B. R. Jaenisch
Kansas Agricultural Experiment Station Research Reports
Seeding rate determines the first yield component of field crops, which is the plant population. However, wheat is less responsive to plant populations than other crops due to the high plasticity in tillering potential, and this responsiveness depends on resource availability. The objective of this project was to evaluate winter wheat population, grain yield, and grain test weight responses to seeding rate and its interaction with variety in a highly managed production system where manageable stresses were limited. Experiments evaluating the response of the wheat varieties ‘Joe,’ ‘WB-Grainfield,’ ‘Langin,’ and ‘LCS Revere’ to seeding rates ranging from 200,000–1,000,000 seeds per …

Most African countries are far from self-sufficient in meeting their rice consumption; in eight countries the production: consumption ratio, ranged from 0.16 to 1.18 in 2012. We show that for the year 2025, with population growth, diet change and yield increase on existing land (intensification), countries cannot become fully self-sufficient in rice. This implies that for the future, a mixture of area expansion and imports will be needed on top of yield gap closure. Further research is needed for identification of most suitable new land for rice area expansion and areas that should be protected.
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Electronic Theses and Dissertations
Non-native honeybees historically have been used to pollinate many crops throughout the United States, however, recent population declines have revealed the need for a more sustainable pollination plan. Native bees are a natural resource that can play an important role in pollination. I used spatial modeling tools to evaluate relationships between landscape factors and native bee abundance, with a focus on the wild native bees that pollinate Maine’s lowbush blueberries. I applied the InVEST Crop Pollination ecosystem spatial modeling tool, which predicts pollinator abundance based on available floral resources and nesting habitat, to the Downeast Maine region. The InVEST model …
High Yield Soybean Management: Planting Practices, Nutrient Supply, And Growth Modification, Evan Sonderegger
High Yield Soybean Management: Planting Practices, Nutrient Supply, And Growth Modification, Evan Sonderegger
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Growers are constantly seeking ways to improve yield in soybean [Glycine max (L.) Merr.]. There has been much interest in the use of selected alternative practices to maximize soybean yield. These practices include planting soybean at higher than recommended seeding rates, planting soybean in narrow rows, breaking apical dominance to induce branching, application of strobilurin fungicides prophylactically to minimize disease and extend the seed filling period, the use of N fertilizer both in furrow and foliar applied, and the use of seed treatments to promote early stand establishment and health. Field studies were conducted at the University of Nebraska …

In 1605 Oliver de Serres, French agronomist, observed that beets contained sugar-and in 1750 Andrew Marggraf, a German physicist, obtained sugar crystals from beets. It was more than 100 years from Marggraf's discovery until the first successful beet sugar factory was developed in the United States at Alvarado, California, in 1870. Since that time beet sugar has become increasingly more important in our national economy. At present continental United States produces a third of her sugar requirements, 70 to 80 percent of which is from sugar beets. The importance of the sugar beet crop in national and world economy is …
