Seed Set And Xenia Effects On Grain Iron And Zinc Density In Pearl Millet, Mahalingam Govindaraj 2015 ICRISAT

Seed Set And Xenia Effects On Grain Iron And Zinc Density In Pearl Millet, Mahalingam Govindaraj

Mahalingam Govindaraj

Three types of seed samples (selfed, sibbed and open pollinated) can be used for mineral analysis in pearl millet [Pennisetum glaucum (L.) R. Br.] and other cross-pollinated crops. Cost effectiveness and reliability of mineral estimates in these types of seed samples have a direct bearing on breeding efficiency. Three sets of experiments using a diverse range of materials were conducted to examine the potential use of selfed and open pollinated (OP) seed samples for the analysis of grain Fe and Zn density in pearl millet. The results of this study showed that reduction in seed set under selfing, a genotype- ...

Different tillage systems can affect the availability of phosphorus (P) by changing the soil environment. The objective of this study was to evaluate the effects and interaction of fertilizer placement, tillage, and varieties for soybean and corn. The experiment was established at two locations in Kansas in 2014. The experimental design was a factorial in a randomized complete block with four replications. Three fertilizer treatments were combined with two tillage systems and two varieties of soybean and corn selected based on contrasting root systems. Plant tissue samples were collected during the vegetative and reproductive stages to evaluate P concentration, P ...


Evaluation Of Secondary And Micronutrients For Soybean Production In Kansas, M. N. Gutierrez, D. A. Ruiz Diaz 2015 Kansas State University

Evaluation Of Secondary And Micronutrients For Soybean Production In Kansas, M. N. Gutierrez, D. A. Ruiz Diaz

Kansas Agricultural Experiment Station Research Reports

Study of secondary and micronutrients is growing because of their potential contribution to yield increases. The objective of this study was to evaluate soybean response to secondary and micronutrient fertilizer application to maximize yields. A randomized complete block design was employed with four replications at five locations during 2013 and five locations in 2014. Treatments consisted of an unfertilized control; micronutrient fertilizer as individual nutrients for boron, copper, manganese, sulfur, and zinc; and a mix of these nutrients using two different placements (dry broadcast and liquid band). Soil samples were collected prior to planting and after harvest. Soybean trifoliates were ...


Good Governance For Achieving Food Security In Ethiopia: Challenges And Issues, Mussie Ybabe, Sisay Asefa 2015 Addis Ababa University

Good Governance For Achieving Food Security In Ethiopia: Challenges And Issues, Mussie Ybabe, Sisay Asefa

International Journal of African Development

Although rice technologies have been introduced in Fogera district over the last two decades, farm household’s food demand was not met as expected. Sustained, intensified and coordinated rice research is the key to curb the problem but impaired due to lack of good governance coupled with weak institutional capacity. This has resulted snowballing effects like little or no discussion among/with farmers on good practices, successes/failures of technology adoption and input delivery; poor linkage of small farmers to market and knowledge gap in Development Agents. Therefore, this study identified and evaluated potential determinants of household food security with ...


The Impact Of Agriculture On African Civilization In The 21st Century, Andrew S. Targowski 2015 Western Michigan University

The Impact Of Agriculture On African Civilization In The 21st Century, Andrew S. Targowski

International Journal of African Development

The purpose of this paper is to define the impact of agriculture on African Civilization in the 21st century. The methodology is based on an interdisciplinary big-picture view of the African Civilizations. The multifaceted layers of civilizations will be analyzed as interdependent with the agricultural development of African societies. Among the findings are: Sub-Saharan Africa falls short of meeting its agricultural needs. Only one of two individual Africans has access to clean and enough water. Energy and supply of electricity are woefully inadequate and unreliable. Agriculture as a foundation for development and modernization for Africa is too limited. Environmental ...

Soybean Planting Date × Maturity Group: Eastern Kansas Summary, I. A. Ciampitti, D. E. Shoup, G. Sassenrath, J. Kimball, E. A. Adee

Kansas Agricultural Experiment Station Research Reports

Optimum planting time for soybean depends on the interaction between genotype and environment (G × E). Four field studies were conducted during the 2014 growing season across eastern Kansas (Manhattan, Topeka, Ottawa, and Parsons). This study explores the impact of planting date (early, mid, and late planting times) on yield for modern soybean cultivars from a range of maturity groups (early, medium, and late groups).

Hog Markets And The Porcine Epidemic Diarrhea Virus, David A. Hennessy

Agricultural Policy Review

Porcine Epidemic Diarrhea Virus (PEDv) has spread rapidly through the United States swine herd since initial diagnosis in spring 2013. By May 2014, it had been identified in 29 of the contiguous states. Incidence has been greatest in the hog dense states and also Oklahoma and Kansas, as shown in Figure 1. Data are number of positives based on sample genetic tests, taken from National Animal Health Laboratory Network (NAHLN), as reported in www.aasv.org/pedv/PEDv_weekly_report_140326.pdf.


Another Strong Quarter For Agricultural Demands, Chad Hart, Lee L. Schulz 2015 Iowa State University

Another Strong Quarter For Agricultural Demands, Chad Hart, Lee L. Schulz

Agricultural Policy Review

Agricultural demand has remained strong through the first half of 2014. Crop and livestock prices have provided good returns because of strong demand. As we move into the summer season, live cattle prices have moved into the $140–$150 range. Feeder cattle prices have topped $200 per hundredweight; and lean hogs have approached nearly $130 per hundredweight. Also, corn and soybean prices offered crop producers positive profit margins during the planting season.


Can Voluntary Adoption Of Agricultural Practices Achieve The Hypoxic Zone Reduction Goals?, Catherine L. Kling 2015 Iowa State University

Can Voluntary Adoption Of Agricultural Practices Achieve The Hypoxic Zone Reduction Goals?, Catherine L. Kling

Agricultural Policy Review

The presence of a “dead zone” in the Gulf of Mexico caused by nutrients (nitrogen and phosphorus) coming from upstream watersheds continues to recur annually. As part of the 2008 action plan promulgated by the Hypoxia Task Force to address the problem, each state with major nutrient contributions to the Gulf was tasked with developing and implementing a nutrient reduction strategy. Most of the 12 states included have begun or completed their plans. A common theme among all states is the focus on voluntary adoption of the practices identified rather than a regulatory strategy.


Can The Trend Of Rural Population Decline Be Reversed?, Georgeanne M. Artz, Younjun Kim, Peter F. Orazem 2015 Iowa State University

Can The Trend Of Rural Population Decline Be Reversed?, Georgeanne M. Artz, Younjun Kim, Peter F. Orazem

Agricultural Policy Review

In 1900, Iowa’s rural population was just shy of 1.7 million, with almost three-fourths residing on farms or in small towns. However, with the exception of the 1990s, Iowa’s rural population has declined in every census over the last 110 years, as shown in Figure 1. By 2010, only 36% of Iowans remained in rural areas.

Technology And Productivity In Us Corn And Soybean, Giancarlo Moschini

Agricultural Policy Review

Competing demands from food, feed, energy, and environmental uses are placing stress on global land resources. To deal with these challenges, much hope rests on sustaining the trend of past productivity growth by developing and adopting new technologies. In this context, there is much to learn from the US experience of tremendous yield gains achieved thanks to improved crop varieties and management practices.


Price Expectations And Risk Profiles Drive Commodity Program Choices, Alejandro Plastina, Chad Hart 2015 Iowa State University

Price Expectations And Risk Profiles Drive Commodity Program Choices, Alejandro Plastina, Chad Hart

Agricultural Policy Review

The optimal commodity program choice depends as much on the specific production system in each farm as on the producer’s expectations about future yields and prices. Furthermore, the risk profile of producers will weigh heavily in the decision. This article illustrates the role of price expectations and risk profiles in commodity program choice using the ISU Farm Bill Analyzer.


Strong Demand, But Inconsistent Profitability, Chad Hart, Lee L. Schulz 2015 Iowa State University

Strong Demand, But Inconsistent Profitability, Chad Hart, Lee L. Schulz

Agricultural Policy Review

With the arrival of fall, the leaves change, the temperatures drop, and agricultural producers prepare for the winter ahead. This winter looks to be a reversal of fortunes across the agricultural complex. Over the past few years, crop producers have enjoyed record prices and profits, while livestock producers have suffered from high feed costs and negative returns. Now, several sectors of the livestock industry are looking forward to strong prices and good profitability. Meanwhile, the crop sector is staring at the lowest returns in several years. While there are some key differences in the structure of crop and livestock markets ...


Crop Insurance In Iowa, Alejandro Plastina, Chad Hart 2015 Iowa State University

Crop Insurance In Iowa, Alejandro Plastina, Chad Hart

Agricultural Policy Review

Farmers across the nation rely heavily on crop insurance as a risk management tool—in Iowa alone over 93 percent of corn and soybean planted area was insured in 2014, but that participation rate hasn’t always been the case. Participation in crop insurance declined substantially in the early 1990s after the mandate that required producers to purchase crop insurance in 1989 and 1990 to collect drought assistance in 1988 dissipated.


Weather Adjusted Yield Trends For Corn: A Look At Iowa, Lisha Li, Dermot J. Hayes, Chad Hart 2015 Iowa State University

Weather Adjusted Yield Trends For Corn: A Look At Iowa, Lisha Li, Dermot J. Hayes, Chad Hart

Agricultural Policy Review

Yield growth in agricultural crops is of importance to those who make long-term projections of food availability and price levels. Menz and Pardey (1983) found that the trend growth in corn yields was lower in the 1970s than in the previous two decades. Tannura, Irwin, and Scott (2008) cited a number of crop experts and seed companies who believe that improved technology, particularity biotechnology, will increase the rate of yield growth in corn. Yu and Babcock (2010) found that percentage losses due to drought have been reduced over time, offsetting one of the major impediments to stronger yield growth. However ...


Food Safety Modernization Act: The Case For Complementary Public Regulation And Private Standards, Sebastien Pouliot, Helen H. Jensen 2015 Iowa State University

Food Safety Modernization Act: The Case For Complementary Public Regulation And Private Standards, Sebastien Pouliot, Helen H. Jensen

Agricultural Policy Review

President Obama signed into law the Food and Drug Administration (FDA) Food Safety Modernization Act of 2010 (FSMA) in January 2011. FSMA is a set of regulations that modifies U.S. food safety laws and extends their scope. FSMA is considered to be the first major reform of U.S. food safety laws since 1938. FSMA specifically targets products that are under the jurisdiction of FDA and thus impacts products such as produce, dairy, seafood, fresh eggs and eggs used as ingredients. The stated objective of FSMA is to shift the focus from response to food contamination to prevention.


Ag Supplies For 2015, Chad Hart, Lee L. Schulz 2015 Iowa State University

Ag Supplies For 2015, Chad Hart, Lee L. Schulz

Agricultural Policy Review

Markets are the mechanism that balance supply and demand for products. Over the course of the past year, we have discussed the demand patterns for agricultural products in the US and the factors that influence that demand. Now it’s time to look at the other half of the marketplace: agricultural product supplies. During the past couple of years, crop and livestock supplies have been moving in opposite directions. Crop supplies have grown as farmers have brought more land into corn and soybean production and weather conditions allowed record yields. Meanwhile, livestock supplies have shrunk as livestock producers reduced herds ...


Characterizing And Comprehending Land Use Change In The Loess Hills Region, Gaurav Arora, Peter T. Wolter, Hongli Feng, David A. Hennessy 2015 Iowa State University

Characterizing And Comprehending Land Use Change In The Loess Hills Region, Gaurav Arora, Peter T. Wolter, Hongli Feng, David A. Hennessy

Agricultural Policy Review

Regional land use change has important implications for ecosystems and the local human population. Metropolitan areas (MAs) are placing increasing emphasis on amenities and the environment when seeking to attract high income workers and their employers. Our interest is in characterizing land use change in Iowa’s Loess Hills Ecoregion (ILHE) that skirts both Sioux City and Council Bluffs MAs. ILHE is a distinctive landform of silty soils up to 200 feet high that were wind deposited just east of the Missouri River floodplain. Covering about 0.7 million acres, the Loess hills stretch north about 200 miles (usually no ...


Mandatory Gmo Labeling?, GianCarlo Moschini 2015 Iowa State

Mandatory Gmo Labeling?, Giancarlo Moschini

Agricultural Policy Review

Genetically engineered (GE) crop varieties have been prominent in US agriculture for many years. First commercialized in the 1990s, they were rapidly adopted by farmers. By 2014, 93 percent of corn and 94 percent of soybean acres were planted with these varieties. Favorable reception of these products was never universal, as objections were voiced by some segments of the public; however, it seems fair to say that the acceptance of this new technology was smoother in the United States than elsewhere. This conclusion has been tested over the last few years by an increased public awareness and activism intended to ...


Nitrogen Management Under Uncertainty: An Investigation Of Farmers’ Decision Processes, Keri L. Jacobs, Quinn Weninger 2015 Iowa State University

Nitrogen Management Under Uncertainty: An Investigation Of Farmers’ Decision Processes, Keri L. Jacobs, Quinn Weninger

Agricultural Policy Review

Des Moines Water Works has recently threatened a lawsuit against three upstream Iowa counties they claim are responsible for excessive nitrate loading in the Raccoon and Des Moines rivers. Excess nitrate loads, which must be reduced before water is safe to drink, is reported to have cost Des Moines taxpayers upwards of $1 million in 2013. The cost of nitrate removal, which could include investment in new treatment capacity, will continue, and may grow, unless steps are taken to reduce nitrate runoff from agriculture. While such water treatment is costly, yield losses may be more costly if rates are capped ...
