Dairy Product Purchasing In Households With And Without Children, Mario Ortez, Courtney Bir, Nicole Olynk Widmar, Jonathan Townsend
Department of Agricultural Economics Faculty Publications
Dairy products are considered a staple in the American diet due in part to their nutritious content and appealing flavor. Consumption patterns may differ among age segments influenced by preferences for fat content and taste in dairy. Furthermore, having children in their household may influence the amount, frequency, and type of dairy products that a consumer chooses to purchase. This study finds that households that frequently bought food for children generally purchased larger quantities of fluid milk and more fluid milk with a higher fat content. Households with children also bought yogurt more frequently than other households. Labeling information of …

Distillers Grains Pre, During, And Post Covid-19: Ongoing Recovery And Structural Demand Implications, Daniel Gertner, Elliott James Dennis
Cornhusker Economics
Prior to the shutdowns caused by the COVID-19 pandemic, distillers grains and other co-products of ethanol production played a crucial role in maintaining the rev-enue stream of dry mill ethanol plants (Irwin 2020). With low crude oil prices over the last half of the decade and corn prices holding steady over the same period of time, the margin for error in the ethanol industry was thin. More than a third of Nebraska’s ethanol plants either temporarily or permanently closed in 2019 (MacroTrends 2020); (York News Times 2019). To prevent similar outcomes, ethanol plants focused on diver-sifying their operations to produce …

Change In Level Water In Pumping-Plant Intake, R.R. Ergashev, B.T. Xolbutayev
Irrigation and Melioration
A decrease in the water level in the pump chamber of the pumping stations leads to the formation of whirlpools in front of the suction pipes. As a result of air intake, the pump unit operates in cavitation mode and their intensive wear occurs. As the data obtained from the Karshi machine channel show, mainly a decrease in design water levels in the downstream waters is observed at the first pumping station. Depending on the number of simultaneously operating pumping units, the minimum water level in the head pumping station should be from 4.5 m to 5.7 m. The received …

Irrigation and Melioration
In the irrigated lands of the Aral Sea Basin, salinization processes are taking place as a result of rising groundwater levels and increasing its mineralization due to the unsustainable use of water and land resources. This, in turn, leads to the withdrawing of arable land and a decrease in crop yields. This is especially the case in the irrigated areas of the lower reaches of the Amudarya and Syrdarya rivers, located in Uzbekistan, southern Kazakhstan, and Turkmenistan. This research was aimed to learn and evaluate the long-term changing behavior of groundwater level and mineralization in the irrigated areas of the …

Coastal erosion is a type of water erosion that causes significant damage to the national economy each year: leaching of overland coastal crops, failure of protective dams, destruction of irrigation canals, dilapidated buildings and structures, among others. To combat leaching, cross-dams are used which are waterproof and water-permeable. The aim of this work was to develop a method for calculating the planned dimension of compressed flow with a transverse dam, which included comparing the lengths of the upper and lower tilt zones, the boundaries of individual zones and the results of research in the laboratory and in nature.

The article deals with the theoretical and practical substantiation of the replacement of an unregulated electric drive of the main technological equipment of cotton refineries with a frequency-controlled electric drive. The influence of a change in the load on the motor shaft on the main parameters of the steady state is considered. In an asynchronous motor, with an increase in the load, slip increases to such a value at which the torque of the motor balances the increased moment of resistance. Considering that when the stator slip resistance is less than the critical one is a small fraction of the …

In our country, repeated crops are sown in newly plowed lands. In such conditions, the use of combined units that perform several technological operations simultaneously in one pass is considered effective. However, due to the inadequacy and validity of the parameters of the working bodies for the quality of pre-sowing tillage in newly plowed lands, there is an increase in the number of passes, fuel consumption, loss of soil moisture and other costs and, as a result, the possibility of timely sowing and friendly germination of repeated crops is reduced . The rational parameters of the new design of disk …

The Role Of Quality Characteristics In Pricing Hard Red Winter Wheat, Shane J. Roberts
Department of Agricultural Economics: Dissertations, Theses, and Student Research
In this thesis, we empirically examine the role of conventional and end-use wheat quality characteristics on the pricing of hard red winter wheat (HRWW). We use detailed quality characteristic data as well as location matched price data for 50% and 100% harvest completion weeks and utilize a hedonic price analysis framework. We find evidence that end-use characteristics, specifically milling and baking quality characteristics, have a statistically and economically significant effect on the price of HRWW. This evidence suggests that, while HRWW producers are not directly paid premiums or discounts for end-use quality, they are paid indirectly through basis. Comparing results …

Preserving Cultural Heritage Through The Valorization Of Cordillera Heirloom Rice In The Philippines, Subir Bairagi, Marie Claire Custodio, Alvaro Durand-Morat, Matty Demont
Agricultural Economics and Agribusiness Faculty Publications and Presentations
For centuries, heirloom rice varieties have been grown on the terraces of the Cordillera Mountains of Luzon, Philippines, terroirs known for their significant historical, cultural, and aesthetic values. However, heritage heirloom rice farming is gradually being abandoned, mainly because of its lower productivity and the struggle of the sector to create a sustainable niche market for heirloom rice by branding its cultural, social, and nutritional values. We propose several demand-side intervention strategies for the valorization of heirloom rice. To support the development of a segmented marketing strategy for heritage farming, we provide evidence on urban consumers’ willingness to purchase heirloom …

Increasing crop yields in an area we recently studied has helped keep farmers competitive and helped to keep the world’s growing population fed. But how much of that yield increase has been due to more favorable climate versus human-controlled factors such as higher input use, irrigation, better genetics, etc.?
