Soil water reserve estimation and vegetation relationships in a Mediterranean sub-humid forested catchment
A simple water balance model was used to calculate soil water reserve in a Mediterranean forested catchment. The relationship between soil water reserve and leaf water potential and stem water content was analysed. The usefulness of these variables as plant water status indicators was tested. The analyses were developed with a seven-year-long database (2001–2007) in the case of soil water content ...

Yield and water use response of cuphea to irrigation in the Northern Corn belt
Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) may be prone to drought stress, yet little is known about the yield response of this new oilseed crop to irrigation. A field study was conducted in western Minnesota on a Barnes loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) in 2002 and 2003 to compare yield and water use of irrigated and nonirrigated cuphea. ...

Interactive effects of carbon dioxide and water stress on potato canopy growth and development
Reductions in potato (Solanum tuberosum L.) canopy growth are observed with mild water stress. Potato growth is enhanced by elevated atmospheric carbon dioxide ([CO2]), but interactions of [CO2] and water stress on canopy formation and dry matter partitioning have not been studied. Two soil-plant-atmosphere research (SPAR) experiments were conducted at 370 or 740 µmol mol–1 [CO2] and six ...

Impact of planting date and hybrid on early growth of sweet corn
Sweet corn (Zea mays L. var. rugosa) is a warm-weather crop that is grown in most of the United States. Normally, it is planted over an extended planting window to provide a continuous supply for the fresh market. However, this planting window exposes the crop to various stresses and weather risks. The objective of this study was to determine the effect of planting date on early growth of sweet ...

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.) ...

8 Main Points of Aquatic Plant Trimming (1)
1. It is best to turn off the Surface Oil Skimmer when trimming Foreground grasses, such as cow Eleocharis parvula, Hemianthus callitrichoides 'Cuba', and Glossostigma elatinoides, have a lower density than water, and there will be a lot of debris floating on the water when trimming. The debris is likely to enter from the surface skimmer into the filter cartridge, causing excessive accumulation ...

Irrigating with saline or seawater
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 ...

Tree, Crop & Plant Stress – A Primer on Abiotic and Biotic Stressors
The natural conditions in which plants and trees grow are neither uniform nor controlled. Many changes or fluctuations, even if they are temporary, can have a negative impact on and stress plants. The factors which can lead to stress can be one of two types: abiotic or biotic. Stress can have serious repercussions on various phases of a plant’s growth and, ultimately, crop productivity. ...

Leaf spectroscopy
Spectroscopy is a precise and non-destructive technique that can tell us about several processes going on in plants and trees. After being integrated into small handheld devices, it can provide instant and accurate results in the field, forests, and laboratories. It replaces several conventional methods, which were time-consuming and often needed weeks of estimation in expensive laboratories. By ...

Water deficit alters canopy structure but not photosynthesis during the regrowth of Alfalfa
Growth of alfalfa (Medicago sativa L.) following the correction of a water deficit will depend in part on the characteristics of the canopy grown during the water deficit. The current study was undertaken to determine the extent to which canopy structure and photosynthetic capacity are affected in alfalfa plants regrowing following defoliation while exposed to a water deficit. The effects of five ...

NIR & spectroscopy in agriculture & crop science
According to a review by Dr. Crocombe, hand-held spectrometers have historically been used by only small groups of people, such as analytical and drug companies. These days, spectroscopy is available in simple low cost devices for a multitude of applications for scientists and non-scientists alike. One of the most prominent uses of spectroscopy has been the use of the technology on leaves for ...

Leaf area - How & why measuring leaf area is vital to plant research
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 ...

Digging deep for new irrigation methods
Irrigation is essential to increase food production. However, competing needs and increasing drought makes water for irrigation scarce. Therefore, new methods and strategies are continuously being tested by scientists to improve food production, accompanied by better water use efficiency. This article will examine how modern field tools are helping in this venture. Irrigation Methods According ...

How to analyze photosynthesis in plants: Methods and tools
Life as we know it would be impossible without photosynthesis. Outside of providing the essential elements that support life on earth, photosynthesis is of special importance to the food and agriculture industry, as well as for ecologists studying climate change. In addition, there are many commercial enterprises which depend heavily on photosynthesis. As a result, there are a plethora of methods ...

Corn response to competition: growth alteration vs. yield limiting factors
Competition mechanisms among adjacent plants are not well understood. This study compared corn growth and yield responses to water, N, and shade at 74,500 plants ha–1 (1x) with responses to water and N when planted at 149,000 plant ha–1. Plant biomass, leaf area, chlorophyll content, reflectance, and enzyme expression (transcriptome analysis) were measured at V-12. Grain and stover yields were ...
