Organic amendments at two levels were given as seed treatments and as foliar sprays. The scientists used leaf area and root area as indicators of water-use along with chlorophyll content, stomatal conductance, leaf relative water content, and membrane permeability. One of the innovative tools used in the experiment to measure ...
Currently, agriculture uses seventy percent of the freshwaters, globally. Available freshwater sources will not be enough to increase food production to feed growing populations in the coming decades. Therefore, there is a concerted effort to grow crops with seawater. Hence, scientists are investigating the various challenges involved in growing plants with saline water. These include greenhouse ...
Salinity inhibits growth and development in crops. Due to the extent of damage salinity causes to agriculture, it is identified as a major threat to food production. Therefore, practices to deal with the effects of salinity on crops are receiving a lot of attention. To be able to provide proper recommendations that are also sustainable, it is first necessary to find out how salinity affects ...
There is no denying the importance of light for the growth of plants; however, there are many other environmental factors—such as temperature, moisture and nutrient availability, and soil type–that also influence plant growth. These factors do not act in isolation and are, many times, correlated. So, it is interesting to see how light works in combination with other resources to ...
The parameters measured were the Leaf area index (LAI), ground biomass, chlorophyll, and relative water content. The scientists used the CI-202 Portable Laser Leaf Area Meter from CID Biosciences to measure leaf area, from which LAI was calculated. The CI-202 ...
Cadmium is a heavy, non-biodegradable metal that is toxic to plants, people, and animals. With increasing pollution and emission of cadmium, its levels in agricultural soils are increasing. The risk to humans is high due to consumption of cadmium-contaminated food. Modern applications of gas analysis and laser measurements are speeding up research in addressing the problem of cadmium stress. ...
Farm Fertilizer - A Double-Edged Sword The excessive use of fertilizers is one of the main causes of the environmental impact of industrial agriculture. The notion that more is better has caused more harm than good to farming, as well as the environment. Therefore, using the right amount of fertilizers is considered an important part of farm management. To this end, there has been a lot of ...
Never before has the interest in preserving natural forests and efficient management of plantations been as great as the present. Demand for wood products is increasing. On the other hand, it is also evident that the remaining forests have to be protected to maintain our quality of life—the very air we breathe depends on them. Therefore, precision management, which has been successfully ...
It is easy to measure leaves, and they are also the parts of a plant most responsive to their environment. The combination of these two factors makes leaf area measurement extremely useful to scientists and growers. Besides, leaves are one of the main plant organs and are responsible for the productivity of a plant, and on a larger scale, of an ecosystem or a farm. Therefore, an understanding of ...
The CI-202 provides instant results and covers 200mm/second. CI-203 Handheld Laser Leaf Area Meter: This leaf meter has a laser beam and an optical motion sensor to take the length and width to calculate the leaf area and perimeter. ...
The amount of light plants receive can be measured in lux by a lux meter. Temperature Plants are affected if the temperature rises or falls below the optimal range. ...

Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. ...

McQuate and his research team assessed the attractiveness of different plant species as roosting hosts for melon fly and oriental fruit fly, B. dorsalis, using the CI-203 Handheld Laser Leaf Area Meter to measure leaf areas of different plant species to permit the standardization of fly catch by ...
The amount of tissue the plant “decides” to expose to the environment is called Leaf Area. Using a Leaf Area Meter, such as the CI-202 Portable Laser Leaf Area Meter or the CI-203 Handheld Laser Leaf Area ...
Our objectives were to compare plant characteristics including height, leaf area index (LAI), chlorophyll meter readings (chlorophyll index), N uptake, weed densities, and residual soil nutrients in a conventional rotation of peanut-cotton-cotton vs. a bahiagrass-bahiagrass-peanut-cotton rotation. ...
Increased biomass productivity could be achieved through double-cropping if extended growth duration could be realized with minimal reductions in growth efficiency relative to sole-cropping. To test this hypothesis, functional growth analysis was used to assess the relative importance of photosynthetic duration and efficiency in determining biomass production by sole-crop corn (Zea mays L.; SC) ...
Peanut production in drought prone areas should be enhanced by the development of cultivars that can fix more nitrogen (N) under drought conditions. ...
Received for publication April 30, 2008. Riparian forests serve an essential function in improving water quality through the filtering of sediments and nutrients from surface runoff. However, little is known about the impact of sediment deposition on productivity of riparian forests. Sediment inputs may act as a subsidy to forest productivity by providing additional nutrients for plant uptake or ...
