City Trees can offset Neighbourhood Heat Islands, Concordia Researcher Says
The idea of the heat island - that densely built-up urban areas are considerably hotter than the rural and semi-rural landscapes that surround them - has been extensively studied and is widely accepted by academics and the public. The idea of the heat island - that densely built-up urban areas are considerably hotter than the rural and semi-rural landscapes that surround them - has been ...

Sprinkler irrigation changes maize canopy microclimate and crop water status, transpiration, and temperature
During a sprinkler irrigation event some water is lost due to wind drift and evaporation (WDEL). After the irrigation event, plant-intercepted water is lost due to evaporation. The water lost causes microclimatic changes which could result in positive or negative plant physiological changes. We studied the microclimatic and physiological changes on two fields grown with maize (Zea mays L.) ...

Spectral water indices for assessing yield in elite bread wheat genotypes under well-irrigated, water-stressed, and high-temperature conditions
The objective of the present work was to determine the relationship between spectral reflectance indices (SRI) and yield in spring wheat (Triticum aestivum L.) in NW Mexico in three environments (irrigated, water-stress, and high-temperature). The SRI were classified into vegetative indices (three indices) and water indices (five indices). The SRI were determined at booting, heading, and ...

Evaluation of yield, quality and crop water stress index of sugar beet under different irrigation regimes
This study was carried out to evaluate the use of the crop water stress index (CWSI) for irrigation scheduling of sugar beet for two years under the semi arid climate of Iran. Statistical relationships between CWSI and yield, quality parameters and irrigation water use efficiency (IWUE) were investigated. Irrigations were scheduled based on 100 (I100), 85 (I85), 70 (I50) and 0% (I0) of plant ...

Two Approaches for Optimizing Water Productivity
Agricultural Research Service researchers in Bushland, Texas, are helping farmers make the most of their water supplies in a region where they depend on the Ogallala Aquifer, a massive underground reservoir under constant threat of overuse. Steve Evett, Susan O'Shaughnessy, and their colleagues at the Conservation and Production Research Laboratory are developing and testing soil-water and ...

How to grow more food with less water
Scientists and farmers collaborate on a quest for more efficient irrigation This story was co-published with Civil Eats, a daily news source for critical thought about the American food system. From reading the weather to choosing a crop, farming has always been a hands-on enterprise. When a farmer wonders how much water a crop needs, a simple test has always sufficed: Grab a handful of soil ...

How LED and HPS Lighting affects air and leaf temperature
How LED and HPS Lighting can affect air and leaf temperature: The Effects of Convective Heat vs. Radiant Heat As growers are educating themselves more on different lighting technologies, we have been faced with questions many times over about what effects different light sources have on temperature and crop production; what is the difference between Convection Heat and Radiant Heat? Anyone ...

The Forest Canopy: Structure, Roles & Measurement
If you are looking for a classic example of the circle of life, consider the forest canopy structure. A forest’s canopy structure is influenced by environmental and soil factors, and it also influences these factors in return. It is an aspect of forest ecology that is receiving more attention in this age of climate change emergency. The canopy structure is often overlooked, with most of the ...
