Irrigation production functions with water-capital substitution

Growth, Capital Shares, and a New Perspective on Production Functions

Standard growth theory implies that steady-state growth in the presence of exponential declines in the prices of computers and other capital equipment requires a Cobb-Douglas production function. Conventional wisdom holds that capital shares are relatively constant, so that the Cobb-Douglas approach might be a good way to model growth. Unfortunately, this conventional wisdom is misguided. Capit...

Engineering Production Functions and Capital-Labor Substitutions in Metal Machining

Alfalfa Sprout Irrigation Water

Salmonella has been associated with a number of recent outbreaks of foodborne illness involving sprouted seeds. In this research, we addressed the design of sensor components intended for use in a fully automated detection system. A real−time PCR assay was developed to detect Salmonella in sprout irrigation water. Specific detection was achieved by targeting a region of the invasion gene, invA....

Optimizing Water Consumption Using Crop Water Production Functions

Response of tomato to irrigation with saline water applied by different irrigation methods and water management stratigies

In a field experiment the effects of irrigation with saline drainage water (seasonal average of 4.5 dS/m) and non-saline water (0.55 dS/m) applied by two different water management strategies (cyclic or blended saline water with non-saline water in different ratios) and two different irrigation methods (drip or furrow) were studied on growth and productivity of tomato (Lycopersicon esculentum M...
