Selection Of The Most Appropriate Tillage System Based On Topsis Model With Emphasize On Impact Of Different Tillage Systems On Yield, Ali Mirzazadeh, Razieh Pourdarbani, Salman Fekri

Emirates Journal for Engineering Research

Among the various agricultural operations, tillage alone accounts for 60% of the energy consumed in agriculture. Other concerns, such as soil compaction, time management, economic issues, porosity reduction, moisture storage capacity, as well as a 25% increase in water and wind erosion, has further fueled efforts to improve tillage methods. In this regard, conservation tillage is more considered by experts. This study was conducted to evaluate important indices of wheat production in different tillage methods. Two plots located in Moghan Agro Co. were selected and were divided into four equal 2.8 hectares. Experiments were performed in randomized complete block design …

Projected Surface Water For Fruit And Vegetable Irrigation Under A Changing Climate In The Us, Marty Matlock, Greg Thoma, Kieu Ngoc Le, Eric Cummings, Zach Morgan, Andrew Shaw

Water Systems

Increasing greenhouse gas concentrations in the atmosphere, resulting in climate impacts, are raising concerns over the hydrologic cycle and its effects upon agricultural productivity. If rainfall patterns change, meeting an increased demand for fruits and vegetables will pose a challenge for domestic production regions in the United States (U.S.). Information on potential water supply scarcity in the current production regions provides decision makers with critical information for risk mitigation for future production. We used a hydrologic balance-based model of historic and future water availability to evaluate risk of available irrigation water to support major fruit and vegetable production the US. …

Validation Of The Perceived Self-Efficacy Scale (Pse) Among Cassava Farmers In Tanzania, Fatihiya Ally Massawe, Fatihiya Ally Massawe, Amani Angumbwike Mwakalapuka

Journal of Humanities and Social Sciences

This paper validated the Perceived Self-Efficacy (PSE) scale as a measurement tool for farmers’ self-efficacy. From the social cognitive theory, self-efficacy is the key determinant of many social-cognitive behaviours, including the adoption of farming technologies. In this paper, PSE was adopted and tested in a two-stage study among cassava farmers in Mara, Mwanza, and Kagera regions of Tanzania. In the first stage, 200 respondents in Serengeti District of Mara region were exposed to the 13 items of PSE scale, while in the second the adopted tool with 11 items was administered to a total of 360 participants in Mara, Mwanza, …

Farm And Ranch Enterprise Budgets: Return To What?, Larry Van Tassell, Jay Parsons, Glennis Mcclure

Cornhusker Economics

Budgets capturing the projected revenues and costs associated with producing and marketing a single commodity are generally called enterprise budgets or cost and return estimates but can also be referred to as profit center budgets. Two of the major purposes for developing enterprise budgets are to determine which enterprises are the most profitable and to determine breakeven prices for use in a marketing plan. Enterprise budgets produced by the University of Nebraska-Lincoln can be found at farm.unl.edu.

Influence Of Elements Of Irrigation Equipment On Irrigation Erosion, M.M. Sarimsakov, O.S. Abdisamatov, Z.T. Umarova

Irrigation and Melioration

Irrigation erosion is a process that has a significant negative impact on agricultural production, which leads to a sharp decrease in soil fertility and productivity. The costs associated with growing crops will increase. Today, more than 720,000 irrigated lands in the country suffer from irrigation erosion. Studies have shown that in typical gray soils with a slope of more than 0.30, intensive irrigation of apple orchards leaches 24.6 tons of soil particles per hectare per season. Improved irrigation, that is, a decrease in the leaching of soil particles during irrigation using transverse barriers, was achieved by 6–12%. Irrigation reduces the …

Can Commodity Prices Be Negative? Revisiting The Events In The Crude Oil Market In April., Fabio Mattos

Cornhusker Economics

Preventive measures adopted during the COVID-19 pandemic have changed our lives and businesses in many ways. Commodity markets have also witnessed unique events that were partially influenced by those changes. In April, for the first time in history, prices in a large exchange-traded futures market turned negative. Crude oil futures prices for May 2020 delivery were traded below zero on April 20 and 21, reaching a minimum of –$40.32/barrel. If I am selling crude oil to you for –$40.32/barrel, it means that I am giving you the contracted amount of crude oil and paying you $40.32/barrel to take my oil. …

Impact Of Covid-19 On Demand For Distillers Grains From Livestock Operations, Daniel Gertner, Elliott James Dennis

Cornhusker Economics

Government and industry responses to COVID-19 cases have created a variety of unique situations in the agriculture industry. "Stay-at-home" orders forced consumers to be homebound, increasing the demand for food in grocery stores while reducing the need for food in restaurants. These caused a series of rapidly changing supply and demand conditions along the livestock supply chain. Meat destined for restaurants need to be repacked and reprocessed to make it compatible to sell in grocery stores. Meat packing plants continued to try to process harvest-ready animals, but a growing number of positive cases among plant workers forced idling, reduced plant …

Increasing Groundwater Recharge Activity In The San Joaquin Valley Of California, Jacob Willhite, Jacob Willhite

Agricultural Education and Communication

Over the past several decades, groundwater has become a primary source of water used for agriculture in California. Surface water available for agricultural use has depleted due to declining rain totals and reallocation to environmental purposes. As a result, groundwater overdraft has become a severe challenge, especially in the San Joaquin Valley of California. This excessive overdraft causes a plethora of issues, one of the most serious being land subsidence (Faunt, Sneed, Traum, & Brandt, 2016). Studies suggest some areas of the San Joaquin Valley have experienced more than a 28-foot drop in the land level since the 1970’s (Alley …
