Early growth of flint maize landraces under cool conditions
Cold stress is a major factor that limits the success of environmentally sound cultivation of maize in central and northern Europe. This study evaluated the early growth of seven groups of Swiss Flint maize landraces (Zea mays L. ssp. mays) of different geographic origin under controlled cool conditions by assessing shoot and root traits. Measurements of plants, subjected to a permanent cold ...

Sand abrasion injury and biomass partitioning in cotton seedlings
Wind blown soil particle abrasion negatively impacts millions of hectares of crops annually. The goal of this study was to examine the effects of wind and wind blown sand abrasion damage on cotton (Gossypium hirsutum L.) seedling biomass partitioning to leaves, stems, and roots. Seedlings of three cotton cultivars were exposed to no wind (untreated controls) or sand abrasive flux densities of 0, ...

Aiming to optimize irrigation levels
With irrigation being used in many spheres of life and food production methods getting diversified, it is not surprising that research on this topic is getting more specialized. Procedures for analysis, which were restricted earlier to big institutions, need to be widely available so that their reach is extended and science will benefit from more in-depth studies. An increasing number of ...

Evaluation of air pollution phytotoxicity downwind of a phosphate fertilizer factory in India
The effects of air pollution on plants downwind of a fertilizer factory at Udaipur, India, were studied using three woody perennials. Seedlings of these species including a shrub (Carissa carandas L.), a leguminous avenue tree (Cassia fistula L.) and a fruit tree (Psidium guajava L.) were grown in earthen pots at different study sites receiving varying levels of air pollution input. Changes in ...

Can changes in canopy and/or root system architecture explain historical maize yield trends in the U.S. corn belt?
Continuous increase in the yield of maize (Zea mays L.) in the U.S. Corn Belt has involved an interaction with plant density. A number of contributing traits and mechanisms have been suggested. In this study we used a modeling approach to examine whether changes in canopy and/or root system architecture might explain the observed trends. A maize crop model was generalized so that changes in ...

A root-zone soil regime of wheat: physiological and growth responses to furrow irrigation in raised bed planting in northern China
Different irrigation methods in wheat (Triticum aestivum L.) result in different water and nutrient use efficiencies and, ultimately, plant growth. A field experiment was conducted during the 2006–2007 and 2007–2008 crop cycles to investigate the effects of furrow irrigated raised bed planting and the effects of flood irrigated conventional planting on growth and productivity in winter wheat. In ...

Choosing the Right Light for Young Plants
Horticulture lighting research has been conducted on young plants (germination, seedlings, plugs and cuttings) for many years. Michigan State University published a series of articles in Greenhouse Grower (see references below) on bedding plant seedlings. In their research, Drs. Wollaeger and Runkle experimented with different LED wavelengths and compared them to fluorescent light on seedling ...

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. ...

Crop yield increased with the addition on Citadel Biocat+ in the digestate
Field applications evaluations of digestate from BioCat+ treated AD plants are under way in three locations in Europe. From initial results and observations it is apparent that the BioCat+ treated digestate has an improved symbiotic effect in the crop rhizosphere. Crops of wheat and maize recently harvested have shown increases in yields of up to 23% higher yields than previously achieved on the ...

Non-Destructive Root Imaging - Webinar and Live Demo
Alright, so, we are just about a full house here already. So, we’ll get started with the presentation. As you should be able to see on your screen, it should say, “A Change of View: Using Root Imaging to Expand your Research by CID Bio-Science.” Online with me is actually our distribution manager, Suzy Truitt. She’ll be helping in the background facilitating with the Q ...

Intro to precision forestry
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 ...

Regulating fertilizer applications in agriculture for healthier crops & environment
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 ...

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 ...

Influence of environment on plants
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 ...
