Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble
Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.
Carbon Dioxide Toxicity In Wheat, Robert Spanarkel
Carbon Dioxide Toxicity In Wheat, Robert Spanarkel
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This research was conducted to quantify short- and long-term effects of atmospheric carbon dioxide on wheat. Growth, development, and yield of the spring wheat cultivar Veery-10 were measured in response to CO2 concentrations of 340 (ambient), 1200, and 2500 μmol moI-1 of CO2 air. These 3 CO2 levels were chosen to provide a control group, a predicted optimal CO2 environment, and a potentially toxic CO2environment, respectively. A recirculating hydroponic system provided a near-optimal root-zone environment that was identical for all CO2 treatment levels. Environmental factors, other than CO2, were …
Morphological Responses Of Wheat (Triticum Aestivum L.) To Changes In Phytochrome Photoequilibria, Blue Light And Photoperiod, Charles Barnes
Morphological Responses Of Wheat (Triticum Aestivum L.) To Changes In Phytochrome Photoequilibria, Blue Light And Photoperiod, Charles Barnes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wheat (Triticum aestivum, L.) plants were exposed to three different levels of phytochrome photoequilibria (φ), two different photoperiods, end-of-day far-red radiation, two different levels of blue (400-500 nm) light, three levels of photosynthetic photon flux (PPF), and two types of high intensity discharge lamp types. Tillering was reduced by lowered φ, by reduced amounts on blue light and by end-of-day far-red. Main culm development was increased by lowered φ, by increased PPF, and was reduced by shortened photoperiod and by reduced blue light. Leaf length was increased by increased PPF, lowered φ, and reduced blue light but was …
The Relationship Between Leaf Area Index And Photosynthetic Temperature Response In Wheat (Triticum Aestivum L.) Canopies, David B. Meek
The Relationship Between Leaf Area Index And Photosynthetic Temperature Response In Wheat (Triticum Aestivum L.) Canopies, David B. Meek
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objective of this study was to determine the effect of increasing leaf area index on the photosynthetic temperature response of a wheat canopy. Hard red spring wheat (Triticum aestivum L. cv. Veery-10) was grown hydroponically in a growth chamber, which also served as the gas-exchange chamber. Gas-exchange parameters were measured on single leaves and on wheat canopies at various leaf area indices. The temperature response curves of the canopy shifted from being steeper with a high temperature optimum to being flatter with a lower temperature optimum as leaf area index increased from 0 to 20.0 m2m …
Seed Phosphorus : Its Effect On Plant Production, Mike Bolland, Mike Riley, Brett Thomson, Blakely Paynter, Mike Baker
Seed Phosphorus : Its Effect On Plant Production, Mike Bolland, Mike Riley, Brett Thomson, Blakely Paynter, Mike Baker
Journal of the Department of Agriculture, Western Australia, Series 4
The amount of phosphorus in the seed of annual crop and pasture species influences production of plants grown from that seed. It appears the more phosphorus there is in the seed, the better the potential yield irrespective of whether fertilizer phosphorus is applied to the soil or not. This article discusses the influence of phosphorus concentration in the seed of annual crop and pasture species on subsequent production. It also explains the difference between phosphorus concentration and phosphorus content in the seed
Wheat Quality For The Japanese Flour Milling And Noodle Industries, Graham Crosbie, Dianne Miskelly, Tim Dewan
Wheat Quality For The Japanese Flour Milling And Noodle Industries, Graham Crosbie, Dianne Miskelly, Tim Dewan
Journal of the Department of Agriculture, Western Australia, Series 4
About one-third of Australia's wheat production is used in the manufacture of Asian noodles. Japan is one of our most important noodle wheat markets. In that country much of the 900,000 to 1,000,000 tonnes of Australian wheat bought each year is used for noodle production. About 70 per cent of this wheat is Australian Standard White (ASW)from Western Australia. ASWis highly regarded for its suitability for the production of white, Japanese-style noodles. The remainder comprises mainly Australian Prime Hard (APH) which is valued for the production of yellow, Chinese-style noodles and for various breads. This article discusses quality aspects associated …
The Segregation Of Wheat For Noodles, Graham Crosbie
The Segregation Of Wheat For Noodles, Graham Crosbie
Journal of the Department of Agriculture, Western Australia, Series 4
The Western Australian segregation of wheat of selected varieties to cater for the requirements of the established Japanese noodle wheat market and an emerging market for this type of wheat in South Korea started in the 1989-90 season. In this article, Graham Crosbie, who pressed strongly for this segregation, explains the background behind its introduction and the need to ensure its success.
