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)...

Production Profitability of Ethanol from Alternative Feedstocks in the Texas Panhandle AgEcon
Almas, Lal K.; Lust, David G.; Brooks, Kathleen R.; Girase, J.R..
The potential of three feedstocks: grain sorghum, sweet sorghum, and switchgrass for ethanol production in the top 26 counties of the Texas Panhandle Region is analyzed using yield and production costs of feedstock, processing cost of feedstock, final demand for ethanol, farm to wholesale marketing margin, and the derived demand price of feedstock. The calculated economic returns per acre of grain sorghum, sweet sorghum, and switchgrass are -$45.37, -$410.19, and -$150.17 respectively under irrigated condition and -$38.25, -$145.09, and -$29.04 respectively under dryland condition. The evaluation in this study demonstrates that ethanol production from grain sorghum, sweet sorghum, and switchgrass in the Texas Panhandle Region is not economically...

Reducing Irrigation Water Demand with Cotton Production in West Texas AgEcon
Almas, Lal K.; Colette, W. Arden; Warminski, Patrick L..
Due to declining water availability from the Ogallala Aquifer and increasing pumping costs, irrigation management options for cotton are analyzed. The study concludes that supplemental irrigation while meeting crop ET requirements is the most profitable option. Switching from corn to cotton production may reduce irrigation water demand in the region.

The Beneficial Impact of Sorting Heavy Cattle at Re-Implant AgEcon
Link, David J.; Almas, Lal K.; Brown, Michael S.; Lawrence, Ty E..
This research examined a simple sorting strategy to reduce the prevalence of heavyweight carcass discounts. Cattle that were identified and sorted off at re-implant had a reduced prevalence of heavyweight carcasses versus unsorted cattle. Re-implant sorting was profitable at pen average in-weights of 800 pounds or less.

The Use of Weather Data and Evapotranspiration Requirements to Estimate the Marginal Value Product of Irrigation and the Profit Maximizing Irrigation Level for Corn in the Texas Panhandle AgEcon
Colette, W. Arden; Almas, Lal K.; Robinson, Clay.
The declining availability of irrigation water from the Ogallala aquifer combined with increasing energy costs make irrigation strategies much more critical. Maximizing yield reduces profit by between $22 and $158 per acre depending on the combination of corn and natural gas prices.

UTILIZING CONDITIONAL PROBABILITIES IN DEVELOPING PRICE EXPECTATIONS FOR SELECTING OPTIMAL MARKETING ALTERNATIVES FOR FIXED RESOURCE COW/CALF OPERATORS IN THE TEXAS PANHANDLE AgEcon
Colette, W. Arden; Almas, Lal K..
The beef cattle enterprises for most of the 91% of producers in Texas with less than 100 cows represent secondary or supplemental enterprises utilizing discretionary labor and fixed physical resources. The decision making process is transformed from a variable resource allocation problem to a fixed resource problem. Reliable price and revenue expectation models are critical to selecting marketing alternatives that maximize the return to the fixed resource allocation. Price expectation models using expected values, price and revenue indexes, and conditional probabilities are developed using monthly average prices for 300-900 lb stocker steers at Amarillo, TX from 1992 to 2002.

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...

Water Conservation Policy Alternatives for the Ogallala Aquifer in the Texas Panhandle AgEcon
Taylor, Robert H.; Almas, Lal K.; Lust, David G..
The continued decline in the availability of water from the Ogallala Aquifer has led to an increased interest in conservation policies designed to extend the life of the aquifer to sustain rural economies in the Texas Panhandle. This study evaluates the effectiveness of five policies in terms of changes in the saturated thickness of the aquifer as well as the impact each policy has on crop mix, water use per acre, and the net present value of farm profits over a sixty-year planning horizon for the region.

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,...
