Improving alfalfa irrigation in The west
Alfalfa grown for forage is a major crop in many areas of the western United States. In the arid and semi–arid west, irrigation is required to obtain economic alfalfa yields. Because alfalfa is a perennial crop with a potentially long growing season, it can use a substantial amount of water. Alfalfa production in Imperial County, CA, has been valued at more than $170 million dollars for ...

How to Improve Apple Conservation by Reducing Bitter Pit
Bitter Pit is a physiological disorder, linked to a calcium deficiency in apples. Symptoms: dark brown or black lesions, results of the breakdown of the cells under the skin, appear on the skin of the fruit only after harvest. Calcium is not very mobile within the trees. Even though soil and leaves are correctly fed with this element, a deficiency can appear on fruits. This is especially true ...

Physiological Injury and Bio-mechanical Injury of Aquatic Plants
Physiological Injury of Aquatic Plants 1. Insufficient Light During the growth, due to insufficient light, the photosynthetic intensity of aquatic plants will be reduced, the normal growth and development will also be affected. For example, red water plants such as Ammania gracilis and Rotala macranda, due to insufficient light, the anthocyanins in the leaves will decrease; while ...

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 ...

Detecting salinity stress in crops
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 ...

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 ...

The Power of Fusing 3D with Multispec
3D assessment of plants became a commonly used technology in plant phenotyping to measure morphological and architectural features of plants. Although, 3D sensors such as PlantEye can be the workhorse for every phenotyping platform, it still lacks the ability to measure changes in color or other spectral information that are an important indicator for the plants physiological ...

Is Horticultural Science in Crisis? What is Needed to Assure Its Future?
"Kenya has a shortage of competent horticultural staff at institutional and commercial levels." "Horticulture is facing a crisis in the United Kingdom." "Is horticulture a withering field in the USA?" "Concerns over shortage of agriculture graduates In Australia." "Uganda's flower sector faces an imminent shortage of qualified managers and supervisors in flower firms." "New Zealand ...

Oxidative potential of UV‐A irradiated or non‐irradiated suspensions of TiO2 or SiO2 nanoparticles on Allium cepa roots
The effect of UV‐A irradiated or non‐irradiated suspensions of agglomerates of TiO2 or SiO2 nanoparticles on roots of the onion (Allium cepa) has been studied. The reactive potential of TiO2 nanoparticles which have photocatalytic potential and the non‐photocatalytic SiO2 nanoparticles with the same size of agglomerates was compared. We measured the activity of antioxidant enzyme glutathione ...

Exploring photosynthesis and plant stress using inexpensive chlorophyll fluorometers
Mastering the concept of photosynthesis is of critical importance to learning plant physiology and its applications, but seems to be one of the more challenging concepts in biology. This teaching challenge is no doubt compounded by the complexity by which plants alter photosynthesis in different environments. Here we suggest the use of chlorophyll fluorometers in the undergraduate plant ...

Elevated atmospheric carbon dioxide and O3 differentially alter nitrogen acquisition in Peanut
Elevated atmospheric CO2 and ozone (O3) may affect productivity of legumes in part by altering symbiotic N2 fixation. To investigate this possibility, measurements of plant biomass, N levels and natural 15N abundance ({delta}15N) were used to examine the effects of elevated CO2 and O3 on N acquisition in field-grown peanut (Arachis hypogaea L.) using open-top chambers. Seasonal 12-h daily average ...

Response of yield heterosis to increasing plant density in maize
Genetic yield improvement in maize (Zea mays L.) has been associated with heterosis and increased tolerance to high plant densities, but the physiological processes underlying heterosis for tolerance to plant density stress have not been identified. The objective of this study was to quantify the response of heterosis for grain yield to increasing plant density, and to examine the processes ...

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.) ...

Effect of fungicide on soybean growth and yield
In response to rising input costs and narrowing profit margins, soybean [Glycine max (L.) Merr.] producers are continually looking for ways to increase soybean yield. One approach being promoted is the use of foliar fungicides, for both foliar pathogen control and nonfungicidal plant physiological effects. The objective of this field experiment was to evaluate a strobilurin and a triazole alone ...
