Capparis Decidua Edgew (Forssk.) Stem Extract Alleviates The Water Stress Perturbations In Wheat (Triticum Aestivum L.) At Early Growth Stage, Muhammad Nawaz, Qasim Ali, Muhammad Azeem, Fehmina Asghar, Hasnain Ishaq, Naeem Iqbal, Sajid -Ur-Rahman

Journal of Bioresource Management

Water shortage is one of the major limiting factors of crop productivity worldwide. This study was planned to explore the impact of Capparis decidua stem extract on wheat varieties (FSD-2008, 12066 and 13348) under water stress condition. Water deficit condition negatively impacted the seedling germination, growth, photosynthetic pigments and ions uptake capacity. Water limited condition significantly (p≤0.05) increased time to attain 50% germination, lipid peroxidation, H₂O₂ and enhanced the antioxidant mechanism to overcome the oxidative stress. Different concentrations of C. decidua extract i.e. Not Soaking (NS), 10%, 20%, 30% and 40% were used for seed …

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 …

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U.S. By addressing …

Colored Wheat Variety Trial, Heather Darby, Rory Malone, Hillary Emick, Haley Jean, Ivy Krezinski

Northwest Crops & Soils Program

There is an interest amongst bakers and the grain industry in the development of colored wheat crosses as a specialty grain that can be marketed outside of commodity markets. Specialty grains can support local farm viability, and well as the viability of small-scale bakers and millers, and can be bred for adaptation to the local climate. Additionally, there is interest in evaluating the antioxidant capacity of colored wheats as they may have potential health benefits due to their antioxidant properties, which could further increase their value as a specialty grain. In 2019, the University of Vermont Extension’s Northwest Crops and …

The Economic Benefits Of The South African Agricultural Research Council’S Wheat Breeding Program: 1992–2015, Matthew James Coale

Graduate Theses and Dissertations

Although classified as an upper middle-income country by the World Bank, food insecurity is still a concern throughout South Africa, as was evident in 2014–2015 when a drought left 22% of households food insecure. As such, agricultural research in South Africa is needed specifically in plant breeding to increase yields and help mitigate future food insecurity. To fill this need, the South African government funds the Agricultural Research Council (ARC), which conducts holistic research on wheat and other crops. Wheat is important to South African food security; due to the significant drop in wheat area planted since the abolishment of …

Trade And Agriculture Policy Options To Improve The Wheat Subsector In Afghanistan, Ghulam Hazrat Halimi

Open Access Dissertations

In Afghanistan wheat availability is important for national food security as it is the key staple food, accounting for over half of calorie intake. The country has imported on average 32% of its wheat consumption over the period 2000-2015, primarily from Pakistan and Kazakhstan. Since domestic production is volatile, consumer well-being depends on access to international markets.

Pakistan, a key supplier of wheat and flour to Afghanistan, has not been a reliable source for Afghanistan to meet its wheat deficit. Pakistan subsidizes and stabilizes its wheat production, and this benefited Afghan consumers before 2008. Pakistan restricted wheat and flour exports …

Estimating Crop Yield Potential At Regional To National Scales, Justin Van Wart, Kurt Christian Kersebaum, Shaobing Peng, Maribeth Milner, Kenneth Cassman

Department of Agronomy and Horticulture: Faculty Publications

World population will increase 35% by 2050, which may require doubling crop yields on existing farm land to minimize expansion of agriculture into remaining rainforests, wetlands, and grasslands. Whether this is possible depends on closing the gap between yield potential (Yp, yield without pest, disease, nutrient or water stresses, or Yw under water-limited rainfed conditions) and current average farm yields in both developed and developing countries. Quantifying the yield gap is therefore essential to inform policies and prioritize research to achieve food security without environmental degradation. Previous attempts to estimate Yp and Yw at a global level have been too …

Positive Price Outlook For Wheat : Implications For Wa Agriculture, Alan Haagensen, Ian Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

After a 40 year period over which wheat prices have dropped by an average of 2.7 per cent annually in real terms, fundamental changes in wheat supply and demand look set to reverse this trend. It is possible that real prices could increase by as much as 4 per cent anually in the medium term.

Alan Haagensen and Ian Wilkinson look at the forecasts for wheat prices and outline the forces that will influence world supply and demands for wheat.

Production Of High-Value Wheats : One Sustainable Answer To The Cost:Price Squeeze, Wal Anderson, Alan Peggs, Doug Sawkins

Journal of the Department of Agriculture, Western Australia, Series 4

Farmers and scientists alike over the past decade have sought to address the declining terms of farm trade (the cost.price squeeze) by increasing wheat yields in ways that will ensure both their economic and ecological survival. Nevertheless, costs have continued to increase as a proportion of the value of the product.

Many farmers have increased their wheat yields substantially and the industry as a whole is more conscious of the quality of its product.

Over the past 10 years or more there has been intense interest in, and considerable adoption of. conservation farming techniques such as minimum tillage, residue retention, …

The Productivity Of Western Australia's Wheat And Sheep Industry, Tim Coelli, Ross Kingwell

Journal of the Department of Agriculture, Western Australia, Series 4

A popular economic lament is that Australian industries and workers are not as productive as they should be. Politicians and economic commentators preach the need for productivity improvement and workplace reform, and criticise inefficiency and lack of endeavour. Can such criticism be fairly levelled at farmers and agricultural scientists? What is productivity and how is it measured? What is the productivity of Western Australia's main agricultural industry — wheat and sheep farming? This article addresses these questions and shows that our wheat-sheep industry can be moderately proud of its productivity record

“The Poor People Had Suddenly Become Rich” A Boom In Maine Wheat, 1793-1815, Jamie H. Eves

Wheat Payments And Protein Content, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

In recent years there has been increasing support from within the Australian wheat industry for the principal of wheat growers recieving payment for their grain according to market value.

Individual loads are now tested for quality characteristics such as hectolitre weight, unmillable material and moisture content.

At present, technology is not sufficiently advanced to enable rapid and accurate analysis of individual loads for all important quality factors.

A more practical system of quality assessment would be one based on allowances for various basic measures (such as hectolitre weight, unmillable material and moisture content), variety (to allow for genetic differences in …

Price, Yield And Net Income Variability For Selected Field Crops And Counties In Nebraska, Boris E. Bravo-Ureta, Glenn A. Helmers

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The primary objective of this study was to establish an empirical estimate of the riskiness of various crops in different regions of Nebraska. For this purpose the variate difference method was used to estimate random variability indexes of prices, yields, and net returns for six Nebraska crops (wheat, soybeans, alfalfa, oats, grain sorghum, corn). The period of analysis included 1957-1976 and one county in each of the eight crop reporting districts was analyzed. Where relevant, both dryland and irrigated alternatives were examined. Most business decision-makers accept more risk only under the conditions that the probability of higher returns accompany risky …
