UTILIZING EXPECTED REVENUE IN SELECTING OPTIMAL MARKETING ALTERNATIVES FOR FIXED RESOURCE COW/CALF OPERATORS IN THE TEXAS PANHANDLE AgEcon
Colette, W. Arden; Almas, Lal K.; Hittle, Chad A..
Beef cattle enterprises for the 91% of Texas producers with less than 100 cows represent secondary or supplemental enterprises. In most cases the operator is depending on surplus or discretional labor and the alternate use of the physical resources is limited due to topography or environmental factors. These characteristics transform the decision making process from a variable resource allocation problem to a fixed resource problem. Monthly average prices for 300-900 lb stocker steers, divided into 50 lb intervals, are analyzed for three market locations for the period 1992-1999. Consistent price roll back is observed as the price per cwt decreases as the weight increases. However, as the reduction in price is more than offset by the increase in value due...

Multi-year Water Allocation: A Policy Analysis for Groundwater Management and Conservation for Irrigated Agriculture AgEcon
Tewari, Rachna; Almas, Lal K.; Lust, David G..
Heavy withdrawals from the most dependable source of groundwater in the Texas Panhandle, the Ogallala Aquifer, create an impending need for implementing water conservation policies. This study evaluates the policy option of multi-year water allocation coupled with water use restriction in four water deficit counties of Castro, Deafsmith, Parmer and Swisher over a sixty year planning horizon. Results indicate that the water use in the study area declines with progressive restriction rates accompanied by a substantial decrease in the net present value of net returns over sixty years and therefore it is important to analyze the socio-economic effects of implementing such a policy alternative.

Groundwater Policy Research: Collaboration with Groundwater Conservation Districts in Texas AgEcon
Johnson, Jeffrey W.; Johnson, Phillip N.; Guerrero, Bridget L.; Weinheimer, Justin; Amosson, Stephen H.; Almas, Lal K.; Golden, Bill B.; Wheeler-Cook, Erin.
The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities.

EVALUATING THE IMPACT OF INTEGRATED PEST MANAGEMENT ON AGRICULTURE AND THE ENVIRONMENT IN THE TEXAS PANHANDLE AgEcon
Colette, W. Arden; Almas, Lal K.; Schuster, Greta L..
Agricultural producers in the Texas High Plains are facing the worst comparative economic conditions since 1913. Under these circumstances it is desirable to evaluate which programs are beneficial to agricultural producers and which ones are not. The concept of Integrated Pest Management was introduced to the Texas High Plains in 1976 and since then many IPM practices have been adopted for the four major crops; corn, cotton, sorghum, and wheat. The reduction in production cost is used as a measure of economic benefit and contingent valuation is used to estimate the value of the environmental benefits. The IPM practices, which have been adopted, reduce the production cost by more than $173 million per year. In addition the practices reduce...

Water use efficiency and maximizing profitability of grain sorghum production in the Texas Panhandle AgEcon
Ahamadou, Aly; Dembele, Mamadou; Almas, Lal K.; Brooks, Kathleen R..
The reduction in the availability of irrigation water and the increase in pumping costs resulting from the decline in the Ogallala Aquifer make good management decisions more critical for the survival of the farm firm and the success of the agricultural sector in the Texas Panhandle. Response functions for irrigation and percentage potential evapotranspiration (PET) in the production of grain sorghum are estimated. The response functions are transferred into value product functions and combined with an irrigation energy cost function to determine the profit maximizing irrigation strategy. Three management decision variables; total water available, the level of irrigation and the water to meet crop ET requirements are evaluated. Grain sorghum yield,...

DECLINING OGALLALA AQUIFER AND TEXAS PANHANDLE ECONOMY AgEcon
Almas, Lal K.; Colette, W. Arden; Wu, Zhen.
The Texas Panhandle is one of the most unique and diversified agricultural areas in the world. Production agriculture contributes $3.41 billion in value-added production and more than $6.32 billion in economic activity annually. Eighty-five percent of the state’s fed beef, 45.8 percent of the wheat, 61.9 percent of the corn, and 23.0 percent of the sorghum are produced in the region. The growing livestock industry has accelerated the demand for feed grains in the area and has increased irrigation water demand. The Ogallala Aquifer is the primary source of irrigation water in the region. The depletion of the Ogallala by the excessive pumping of water is threatening the rural economy of the area. There is a critical need for developing sound water...

Partial Factor Productivity, Agronomic Efficiency, and Economic Analyses of Maize in Wheat-Maize Cropping System in Pakistan AgEcon
Amanullah; Almas, Lal K..
Getting maximum benefits from cereals do not lie in reducing N-rate and its number of splits but lowering cost per unit cereal production through higher yields. Field experiments were conducted on maize (Zea mays L.) at the New Developmental research Farm of NWFP (Northwest Frontier Province) Agricultural University Peshawar-Pakistan during 2002-03 and 2003-04 in order to investigate effects of variable rates of N and its time of application on the partial factor productivity (PFPN), agronomic efficiency (AEN), net returns (NR), value-cost ratio (VCR) and marginal returns (MR). The 2 x 3 x 6 factorial experiment was designed having two plant densities (D1 = 60,000 and D2 = 100,000 plants ha-1) and three N levels (N1 = 60, N2 = 120 and N3 = 180 kg N ha-1)...
