A Review On Overcoming Dual Challenges For Maize Cropping Under High Plant Density: Stalk Lodging And Kernel Abortion, Alam Sher, Javed Iqbal, Wajid Nazeer, Muhammad Mudassar Maqbool, Muhammad Nadeem, Sajid Faiz, Shahbaz Khan

Journal of Bioresource Management

Increased optimal plant density is necessary in ensuring future food security by increasing crop productivity. However, maintaining relatively high plant density has to overcome two challenges i.e. kernel abortion and stalk lodging. The response of maize to increased plant density and the effects of increased plant density on maize productivity were discussed in this research. Increased plant density induces increased plant height, causes low photosynthetic capacity, limits the carbohydrate supply and increases kernel abortion. Also, increased plant density incurs a high risk of stalk lodging due to increased ear height and diminished stem diameter associated with reduced vascular bundles that …

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Empirical evidence on the responsiveness and sensitivities of food consumption to its drivers is vital for conducting economic studies. Despite recent attempts to provide such estimates, much empirical work remains to be done considering the prevailing shifts in consumption trends in the Philippines. Price and expenditure elasticities are estimated for seven food categories for rural and urban Filipino households, using Stone–Lewbel (SL) price indices and the quadratic almost-ideal demand system (QUAIDS) model. We used multiple years (2006, 2009, 2012, 2015, and 2018) of the Philippines Family Income and Expenditure Survey (FIES) to estimate the food demand system. The results show …

School Breakfast And Student Behavior, Andres Cuadros-Menaca, Michael R. Thomsen, Rodolfo M. Nayga Jr.

Agricultural Economics and Agribusiness Faculty Publications and Presentations

The School Breakfast Program (SBP) is one of the largest nutrition assistance programs serving school-aged children in the US. It provides reimbursement to states for the operation of breakfast programs in schools. Student participation in the SBP is, however, much lower than the National School Lunch Program (NSLP). Because missing breakfast could result in hunger that could then influence children's interpersonal relations and classroom behavior (i.e., disciplinary infractions), some schools have implemented breakfast after the bell (BAB), which encompasses alternative breakfast delivery methods that make breakfast available to children after the school day commences. We use a difference-in-differences design with …

Regional Minimums In The U.S. Beef Complex, Elliott James Dennis, Bradley Lubben

Center for Agricultural Profitability

This report shows how the currently proposed policies differ; shows how these policies have aligned with historical market behavior; provides alternative specifications to regional minimums; and suggests policy alternatives to regional minimums.

The main purpose of this report is to show how current and potential alternative specifications of regional minimums would have historically aligned with observed market behavior. However, the fundamental question in the debate of the validity and effectiveness of regional minimums first rests on whether robust price discovery has historically occurred over time and within each USDA-AMS region. If there has been a lack of price discovery during …

Identifying Available Resources And Agricultural Practices Useful In Soil Fertility Management To Support Orange-Fleshed Sweet Potato Cultivation On Smallholder Farms In Mozambique, Rafaela Feola Conz, Engil Isadora Pujol Pereira, Abdul Naico, Maria Isabel Andrade, Johan Six

School of Earth, Environmental, & Marine Sciences Faculty Publications

Orange-fleshed sweet potato is an important source of macro-and micronutrients for humans, particularly in resource-poor rural communities. However, sweet potato cultivation removes large amounts of nutrients from the soil. Hence, soil fertility replenishment is vital to secure long-term food production. The lack of access to fertilizers hinders the ability of farmers to supply and replenish soil nutrients, intensifying food insecurity. This study aimed at identifying locally available organic residues and agricultural practices with potential application in soil fertility management to prevent soil degradation in southern Mozambique. We conducted a survey to gather information on the farmers’ demographics and farming systems …

Three Essays On Climate Smart Agriculture And Multidimensional Poverty In Uganda, Sarah Kagoya

LSU Doctoral Dissertations

Agriculture is the backbone of the Ugandan economy. It contributes about 23.1% to the gross domestic product and employs approximately 72% of the total labor force (World Bank, 2021). However, Uganda suffers from low agricultural productivity resulting from pests and diseases, changing climate, deteriorating natural resources, and lack of modern factors of production. In addition, land deterioration and fluctuating weather patterns lead to reduced crop productivity and cause food insecurity in the country. Climate-Smart Agriculture (CSA) can help transform the agricultural system and ensure food security in the country.

The dissertation is written in a three-essay format. The first essay …

Assessment Of Bacterial Inoculant Delivery Methods For Cereal Crops, Yen Ning Chai, Stephanie Futrell, Daniel P. Schachtman

Department of Agronomy and Horticulture: Faculty Publications

Despite growing evidence that plant growth-promoting bacteria can be used to improve crop vigor, a comparison of the different methods of delivery to determine which is optimal has not been published. An optimal inoculation method ensures that the inoculant colonizes the host plant so that its potential for plant growth-promotion is fully evaluated. The objective of this study was to compare the efficacy of three seed coating methods, seedling priming, and soil drench for delivering three bacterial inoculants to the sorghum rhizosphere and root endosphere. The methods were compared across multiple time points under axenic conditions and colonization efficiency was …

Ecology Of Periphyton In A Subtropical River Floodplain, Kamela De Gallardo

LSU Doctoral Dissertations

The Atchafalaya River Basin (ARB) in southcentral Louisiana, USA, is a large and biologically diverse floodplain surrounding the Atchafalaya River (AR), which is the largest distributary of the Mississippi River, receiving 30% of the combined daily discharge of the Mississippi and Red Rivers. Annual flooding facilitates exchange between the AR and its floodplain and is thought to give rise to the high productivity of the river-floodplain system. Primary production within the aquatic ARB is driven by periphytic algae, phytoplankton, and aquatic macrophytes, however, very little is known about periphytic algal assemblages in floodplain systems. In this study, artificial substrates were …

Drought is a recurring event faced by many cow/calf producers across the nation. As drought events increase in their severity, it is important for cattle producers to have a management plan to mitigate the economic effects of drought. Two of the most common strategies for mitigating the effects of drought include buying additional feed and depopulating a portion of the herd. This fact sheet reviews strategies that will guide the decision-making process to cull cattle during drought.

Reducing Tillage Affects Long-Term Yields But Not Grain Quality Of Maize, Soybeans, Oats, And Wheat Produced In Three Contrasting Farming Systems, Kirsten Ann Pearsons, Emmanuel Chiwo Omondi, Brad J. Heins, Gladis Zinati, Andrew Smith, Yichao Rui

Agricultural and Environmental Sciences Faculty Research

Reducing tillage has been widely promoted to reduce soil erosion, maintain soil health, and sustain long-term food production. The effects of reducing tillage on crop nutritional quality in organic and conventional systems, however, has not been widely explored. One possible driver of crop nutritional quality might be the changing soil nitrogen (N) availability associated with reduced tillage in various management systems. To test how reducing tillage affects crop nutritional quality under contrasting conventional and organic farming systems with varied N inputs, we measured nutritional quality (protein, fat, starch, ash, net energy, total digestible nutrients, and concentrations of Ca, K, Mg, …
