Temporal Dynamics Of Irrigation Characteristics In South Carolina, Selvalakshmi Selvaraj, Jose O. Payero, Dana B. Turner

Journal of South Carolina Water Resources

Irrigation plays a vital role in stabilizing crop production under climatic variability in the southeastern United States. However, limited long-term empirical evidence exists on how irrigation practices, water sources, and energy demands have evolved in South Carolina. The aim of this study was to examine temporal changes in irrigation characteristics in South Carolina. The analysis utilized two decades (2003–2023) of data from the United States Department of Agriculture – National Agricultural Statistics Service, Irrigation and Water Management Surveys. Results showed a 65% increase in the number of irrigated farms and 260% expansion in irrigated acreage over the twenty-year period. Groundwater …

To Hold Or Sell Breeding Cattle In The Rangelands, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

In a dry season where feed, water and finances are limited, removing less productive animals as soon as possible is a good option. This will free up feed for more productive animals and help preserve ground cover.

This page provides some of the information and a process for making decisions about holding or selling breeding cattle.

Economic Impacts Of Abolishing Vertical Integration In The Us Pork Industry, Konstantinos Giannakas

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

This paper develops a multi-market framework of analysis of vertical relationships in pork production and game theoretic models of heterogeneous firms to examine the economic, market and welfare impacts of abolishing vertical integration in the US pork sector. Different scenarios on the causes of vertical integration and the potential states of nature that can emerge after the removal of this vertical market arrangement are considered within this framework. Analytical results are consistent across the different scenarios and forms of strategic interactions between pork producers and indicate that the abolishment of vertical integration in the US pork sector will hurt pork …

Jurnal Ilmu Ternak Universitas Padjadjaran

Abstract

Feed plays an important role in livestock metabolism, especially to support growth, maintain body condition, and production. Therefore, efforts are needed to find high-quality feed ingredients that are easy to obtain, sustainably available, do not compete with human needs, are non-toxic, and economical. One alternative feed ingredient that can be optimized to reduce feed costs is industrial waste, such as coconut meal and palm kernel meal. This research was conducted at the Laboratory of the Faculty of Animal Husbandry and Fisheries, Tadulako University, Palu, for five weeks, namely from March 19, 2022 to May 20, 2022. A total of …

Cost Effects Of Adding Poultry To Organic Vegetable Production Systems In California, Iowa, And Kentucky, Kwanele Magwaba, Alejandro Plastina, Ajay Nair, Maurice Pitesky, David J. Gonthier, Anne Carey, Faye Duan, Viktor Halmos

Journal of Applied Farm Economics

This study evaluates the economic viability of integrating poultry into organic vegetable crop rotations over three years in Kentucky and Iowa and two years in California. Given the growing global demand for food and heightened environmental awareness, understanding the financial implications of such integrated systems is crucial. Our comprehensive experiment compared integrated poultry-vegetable rotations with vegetable-only systems, assessing costs, revenues, and key factors influencing profitability. While integrating poultry reduced vegetable production costs by up to 10% in some cases, overall system costs increased due to high poultry expenses. Break-even poultry prices averaged $8/lb for low-density systems and $7 for high-density …

An Analysis Of Cover Crop Adoption In Southeastern Row Crop Systems: Benefits, Challenges, And Policy Implications, Madison H. Mccay, Yangxuan Liu, Alejandro Plastina, Guy A. Hancock, Amanda R. Smith

Journal of Applied Farm Economics

Cover crops, utilized by producers to provide seasonal soil cover between cash or forage crop cycles, play a significant role in diversifying crop rotations and enhancing environmental sustainability. This research aims to assess the economic impact and farmer perceptions of cover crop adoption in the southeastern United States, particularly in Georgia, Alabama, and Florida. Producers show interest in adopting cover crops with increasing awareness of their benefits, such as improved soil health, water quality, weed suppression, and reduced soil erosion. Despite these advantages, adoption rates are hindered by economic challenges. A survey conducted from January to March 2021 gathered data …

Are Returns From Commercial Farming Heterogeneous? Case Of Wheat Growers In North India, Saroj Verma, Kirtti Ranjan Paltasingh, Phanindra Goyari

Journal of Applied Farm Economics

Contract farming (CF), generally a commercial farming system, is widely perceived as a welfare enhancement strategy in rural areas where agriculture is the major source of livelihood. However, those welfare implications have not been adequately explored in Indian agriculture. So, this study examines the returns to CF and the heterogeneity in their returns across various groups of wheat growers in Haryana, a leading agrarian state in India. Using an endogenous switching regression model on cross-sectional data of 754 farm households, the study found that CF adopters would lose 27% of their gross margins and 11% of their crop output if …

Optimal Drought Management Actions For Cattle Operations On The Uintah And Ouray Indian Reservation, Kynda R. Curtis, Tatiana Drugova, Man-Keun Kim

All Current Publications

In this fact sheet, we examine the drought management options available to cattle operations on the Uintah and Ouray Reservation, the largest Native American reservation in Utah. Specifically, we discuss the results of a study that evaluated the economic outcomes of two common drought response strategies: herd reduction and supplemental hay purchases. We also provide recommendations for ranchers on optimal strategies, i.e., those that maximize profits for two rancher types, differentiated by their willingness to accept risk (risk-neutral) or avoid it (risk-averse).
