Methods for creating stomatal impressions directly onto archivable slides
Stomatal density has been shown to be a primary determinant of crop yield, water use efficiency, and limitation to CO2 assimilation rate. Widely used methods of assessing stomatal density sample relatively small regions of the leaf, are labor intensive, or do not yield stable archivable samples for revisiting samples. We describe several methods of producing such epidermal impressions that yield ...

The ratio of transpiration to evapotranspiration in a rainfed maize field on the Loess Plateau of China
Maize (Zea mays L.) is a major crop on the Loess Plateau, and calculating the ratio of transpiration to evapotranspiration (T/ET) of maize is important for estimating field water balance. In this study, the sap flow method was adopted to measure transpiration (T) characteristics of maize. In order to calibrate the sap flow gauge, the sap flow rate was compared to the leaf T determined by the ...

Gas exchange and transpiration ratio in Sorghum
Decreased water availability and increased food demand worldwide require development of more water-efficient crops. This study was conducted to examine preflower transpiration ratio (CO2 assimilation rate [A]/transpiration rate [E], A:E) in four inbred sorghum [Sorghum bicolor (L.) Moench] lines and 12 of their F1 hybrids in terms of phenotypic and genetic variation, inheritance (i.e., additive ...

Can water use efficiency be modeled well enough to impact crop management?
Crop water use efficiency (WUE, yield per unit of water use) is key for agricultural production with limited water resources. Policymakers and water resource managers working at all scales need to address the multitudinous scenarios in which cropping systems and amounts, timing and methods of irrigation, and fertilizer applications may be changed to improve WUE while meeting yield and harvest ...

Ecohydrological modeling of irrigation scheduling of maize using time series analysis in the temperate region of Kashmir valley, India
Water, one of the most crucial inputs of irrigation, should be utilized judiciously to identify appropriate strategies for planning and management of irrigated farmland. The present study was conducted for the crop maize (Zea mays), grown mainly in the rabi-season (July–October), to evaluate the irrigation water requirements in the temperate region of Kashmir Valley, India during the ...

Self-Cleaning Irrigation Water Filters
One of the critical components of successful agriculture is irrigation, which ensures that crops receive the water they need to thrive. However, using untreated or impure water for irrigation can have detrimental effects on crops and the environment. Self-cleaning irrigation water filters have emerged as a groundbreaking solution to this problem. The Importance of Self-Cleaning Irrigation Water ...

O3 sensitivity in a potential C4 bioenergy crop: Sugarcane in California
The C4 perennial grasses have many potential virtues as bioenergy crops—high productivity and water use efficiency, multiyear crop cycle that minimizes replanting costs, and wide environmental adaptation. In the productive San Joaquin Valley (SJV) of California, these species also confront high levels of ozone (O3) air pollution. It is often assumed that C4 species will exhibit tolerance to O3, ...

Water efficiency of agricultural production in China: regional comparison from 1999 to 2002
We apply stochastic frontier analysis (SFA) techniques to a provincial level data set to measure technical and water efficiency in China's agricultural production from 1999 to 2002. The determinants of the efficiencies are identified together with the physical determinant structure of the irrigation factor, which refers to the water use per irrigated land area. The study yields the following ...

Marginal value of natural water in agriculture: a study in the suburbs of Mekelle City, Ethiopia
In areas where markets for natural water are lacking, information on its marginal value can be an important tool for proper pricing to achieve efficient allocation of the resource. This article investigates the marginal value of natural water (rainwater used as a proxy) in agricultural crop production in the suburbs of Mekelle City, Ethiopia, by econometrically estimating individual value ...

Precision application of water for peri-urban horticulture
Vegetables are grown in the peri-urban zone throughout Australia on various soil types and in various climates. In order to grow vegetables throughout the year, irrigation is generally needed to supplement natural precipitation. Peri-urban horticulture in the Sydney region supplies fresh vegetables, cut flowers, turf and other farm produce. Competition for water and environmental impacts (e.g. ...

In-situ soil moisture conservation: utilisation and management of rainwater for crop production
The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally cultivated fields. ...

Validating the FAO aquaCrop model for irrigated and water deficient field maize
Accurate crop development models are important tools in evaluating the effects of water deficits on crop yield or productivity. The FAO AquaCrop model predicts crop productivity, water requirement, and water use efficiency (WUE) under water-limiting conditions. A set of conservative parameters [calibrated and validated for maize (Zea mays L.) in a prior study and considered applicable to a wide ...

The effect of rigid scheduling on productivity and water-use of potatoes (Solanum tuberosum L.) grown under small-scale irrigation
This paper evaluates the results of a study highlighting the effect of rigid scheduling on crop water use and soil water extraction patterns, crop coefficients, crop response functions and water-use efficiency (WUE). The cumulative Penman potential evapotranspiration (Etp) at the end of the season reached around 400 mm and the total depth of water applied between planting and harvest through ...
