Corn (Zea Mays L.) Production In Living Mulch Systems, Grazing Potential, And Economic Viability, Marcia Peireira Quinby Aug 2022

Corn (Zea Mays L.) Production In Living Mulch Systems, Grazing Potential, And Economic Viability, Marcia Peireira Quinby

Doctoral Dissertations

Living mulch (LM) is a practice in which forages are grown simultaneously with the main crop, serving as a living cover throughout the growing season. The LM systems were developed to alleviate concerns of soil depletion and finding ways to reduce tillage negative effects on soil productivity. In addition, when legumes are use can decrease the reliance on N fertilizer. The use of corn in LM have been previously studied due to the crop being a large commodity in the U.S.; In addition, the ability to graze the LM after corn production can increase the land use efficiency. To determine …


Cover Cropping In Soybean-Corn Rotation System: Economic, Agronomic, And Soil Fertility Impact, Jose Rodolfo Mite Jun 2020

Cover Cropping In Soybean-Corn Rotation System: Economic, Agronomic, And Soil Fertility Impact, Jose Rodolfo Mite

LSU Doctoral Dissertations

Planting winter-annual cover crops prevent soil erosion, reduces water runoff, and improves soil structure and soil quality. This research was conducted from 2017 to 2019 to evaluate the nutrient turnover of different species of cover crops in soils under different row crop production systems in Northeast and Central Louisiana. In Northeast Louisiana (Site 1, 2, and 3), treatments (cover crops and no cover crop) were arranged in a strip trial with three replications. At the Ben Hur Research Station, the treatments included three planting dates (September, October, and November) with [7 kg ha-1 of phosphorus (P) and potassium (K)] …


Performance Of The Producer Accumulator In Corn And Soybean Commodity Markets, Chad Te Slaa Jan 2017

Performance Of The Producer Accumulator In Corn And Soybean Commodity Markets, Chad Te Slaa

Electronic Theses and Dissertations

This research quantifies risk reduction and performance of the producer accumulator contract in corn and soybean markets. To quantify performance, we use three alternative theoretical pricing models to estimate historical producer accumulator contract specifications in corn and soybean markets. We then compare the performance of the producer accumulator to eight alternative agricultural marketing strategy portfolios that are also used in new generation grain contracts. The performance measures we compare are: average bushel price that would be received by the producer, daily portfolio risk, and the Sharpe ratio. The period we examine performance was between 2008 and 2017. We investigate performance …


An Evaluation Of The Impact Of The Adoption Of The Onboard Module Building Cotton Harvest System On The Economic Competitiveness Of Cotton Production In Louisiana, Natalia Estefania Latorre Jan 2014

An Evaluation Of The Impact Of The Adoption Of The Onboard Module Building Cotton Harvest System On The Economic Competitiveness Of Cotton Production In Louisiana, Natalia Estefania Latorre

LSU Master's Theses

Planted acreage of cotton in Louisiana has decreased over the past several years due to higher cotton variable production costs, stagnant cotton market prices, and higher grain yields and market prices for corn and soybeans. The general objective was to determine the economic impact of the adoption and use of an onboard module building cotton harvest system on the ability of the cotton enterprise to compete for planted acreage in the mixed crop farming areas of Louisiana. Specific research objectives included the estimated of comparative ownership and operating costs for the module building harvest systems relative to existing basket/module builder …


Risk Return Of Farmer-Elevator Contracts For Soybeans And Corn In Arkansas, Marei Undine Houpert Dec 2013

Risk Return Of Farmer-Elevator Contracts For Soybeans And Corn In Arkansas, Marei Undine Houpert

Graduate Theses and Dissertations

In Arkansas the contribution of Agriculture to the states GDP is comparatively high. To help farmer's return risk the grain industry developed several marketing tools to support farmers. Literature in this research field finds different results for different locations, commodities, marketing tools and marketing years. As Agriculture in Arkansas is important for its economy this study focuses on soybeans and corn produced in the fertile north-eastern area of Arkansas that uses Memphis Tennessee as a spot market palace. The examined marketing tools are pre-harvest futures hedges and forward contracts as well as post-harvest storage strategies and minimum price contracts. All …


Stochastic Trends In Crop Yield Density Estimation, David I. Maradiaga Jan 2010

Stochastic Trends In Crop Yield Density Estimation, David I. Maradiaga

LSU Master's Theses

The search for improved methods of estimating crop yield density functions has been a theme of recurrent research interest in agricultural economics. Crop yield density functions are the statistical instrument that generates probability estimates of yield risk, and risk is an important decision variable in production agriculture. Recent research in crop yield density estimation suggests that yield probability estimates can be sensitive to the way yield data are filtered, and if true, then the search for an “adequate filter” is warranted. Such a quest is pursued in this study. It is proposed that unit-root tests can be used to identify …


An Analysis Of Government Policy Impacts In The Ethanol And Sugar Markets, Hassan Marzoughi_Ardakani Jan 2009

An Analysis Of Government Policy Impacts In The Ethanol And Sugar Markets, Hassan Marzoughi_Ardakani

LSU Doctoral Dissertations

ABSTRACT This study determines the impact of U.S. government policies on U.S. ethanol market and its consequences for the U.S. corn, sugar, and HFCS markets. Using corn as the primary input in ethanol and HFCS production in the United States, along with the substitutability between sugar and HFCS, has linked the U.S. ethanol market to the U.S. HFCS, sugar, and corn markets. To address the problem, two sets of data, quarterly and annual data, were collected and a simultaneous econometric model was constructed. Estimated results show that the “2007 Energy Independence and Security Act” will increase the domestic corn price …


An Economic Analysis Of Pre-Harvesting Marketing Strategies And Financial Performance, Manuel Duarte Filipe Jan 2002

An Economic Analysis Of Pre-Harvesting Marketing Strategies And Financial Performance, Manuel Duarte Filipe

LSU Master's Theses

Risk is an important concern in the management of a farm business. The rising input prices along with the variability in the farm commodity prices may result in a risk environment. Government programs have generally provided income support to farmers. However, there has been considerable discussion regarding this support in recent years. The farm act of 2002 and farm bill of 1999 are good examples of such discussions. These uncertainties emphasize the need to improve information for farm's income risk management, and make some one ask if there is not out there any alternative way of managing income risk besides …
