A comparison of three isolines of cotton differing in fiber color for yield, quality, and photosynthesis
Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are eco-friendly for the textile industry because they omit the dyeing process and reduce harmful effluent liquor. However, the low yield and quality of CCFs have greatly affected their development. Limited information is available on the reasons for the low yield and quality of CCFs. The aim of this 2-yr investigation was to compare ...

Effect of recycled water applied by surface and subsurface irrigation on the growth, photosynthetic indices and nutrient content of young olive trees in central Iran
Water shortage has encouraged the quest for alternative sources of water for food production and agricultural development. Recycled water (RW) is one of the most available water resources with great potential for use in farm irrigation. This experiment was carried out to investigate the use of RW as the irrigation source and its application method, subsurface leaky irrigation (SLI) system or ...

Evaluation of nitrogen sources and application methods for nitrogen-rich reference plot establishment in corn
Five different N sources were compared with null N treatment to evaluate their performance for N-rich reference plot establishment in corn (Zea mays L.). The sources, including calcium ammonium nitrate (CAN), urea ammonium nitrate (UAN), polymer-coated urea (PCU) and environmentally smart nitrogen (ESN) in 2007 and 2008, and urea (URE), were broadcast or in-soil banded at the rate of 225 kg N ...

Project Oyster Case Study
Project Overview Oysters play an important role in maintaining balance in aquatic environments. Due to their method of ingesting food by filtering water around them, they act as living purifiers. In fact, they thrive on excess nutrients and algae that may be harmful to other organisms. This property makes them a viable natural solution to managing waterways affected by phytoplankton blooms caused ...

Morphological, anatomical, and physiological changes of orchardgrass leaves grown under fluctuating light regimes
The physiological and anatomical adaptability of pastures growing under trees in silvopastoral systems can alter the efficiency of conversion of energy to dry matter (DM). This study was conducted to determine the effects of different fluctuating light regimes (from 24 to 100% transmissivity) on leaf physiology, morphology, anatomy, and structure of orchardgrass (Dactylis glomerata L.) in a ...

Light Spectras and Absorption Curves for horticulture
When we talk about plants and their interaction with light, we mostly talk about photosynthesis. But this is only a small part of the story, there are numerous other mechanisms controlled by light. This article aims to help understanding the different mechanisms. Due to the complexity, we just give an overview of the interaction of absorption spectra. It is important to ...

Creating the Perfect Environmental and Atmospheric Conditions for Vertical Farming
The global population is rapidly expanding, and new technologies are required to enable us to keep up with rising food demands. Vertical farms provides a secure supply of food year-round while using minimal space, water, and energy. Creating the perfect environment, and especially the perfect CO2 atmosphere, in vertical farms is essential for optimizing crop yields and farm economics. ...

How to Analyze Photosynthesis in Plants: Methods and Tools
Photosynthesis: Why is it important? 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 ...

Guest Post: Using Plant Science Tools to Monitor and Restore a Native Hawaiian Forest
Native Forest Restoration and Monitoring Project Report #4 November 3rd, 2016 by Mihaela Ryer and Michael Ryer October is known as Ikua in the Hawaiian calendar. It's the month when, according to the Hawaiian folklore, dark storms arise, sea roars, thunder roars, birds roar. We haven’t heard any roaring birds, but certainly had our share of dark storms, thunder and roaring seas. October ...

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 ...

The latest advances in photosynthesis measurement
Photosynthesis is undoubtedly one of the most important physiological processes on Earth. It is the process by which plants, algae, and bacteria produce food. Photosynthesis makes these organisms the primary producers of the earth, as all other organisms feed on them for their energy source. People depend on this important process for most of their needs: food, fiber, fuel, timber, etc. Also, ...

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 ...
