Flowering phenology and synchrony between volunteer and cropped spring wheat: Implications for pollen-mediated gene flow
Genetically engineered (GE) wheat (Triticum aestivum L.) volunteers could present a problem in cultivated wheat because they may facilitate movement of a GE trait to other volunteers or non-GE wheat crops. However, volunteers can emerge periodically throughout the growing season and, thus, flowering overlap with the crop may be largely asynchronous, presenting a significant barrier to gene flow. ...

Haploidy in cultivated wheats: induction and utility in basic and applied research
The usefulness of haploid plants in basic research in cytogenetics, genetics, evolution, and practical plant breeding is well known. Haploid plants provide an efficient research tool for studies on induced mutagenesis and genetic transformation. They also help elucidate the genetic control of chromosome pairing inherently present in allopolyploids such as bread wheat, durum wheat, and oats. ...

Watermills in the historic irrigation system ‘Palmeral de Elche’, Spain: an example of early hydropower exploitation
With more than 180,000 date palms, the Palmeral de Elche is the largest palm grove in Europe. In 2000, United Nations Educational, Scientific and Cultural Organization (UNESCO) declared a part of it a World Heritage Site. Actually, the Palmeral is a historic irrigation system with rows of palm trees flanking rectangular fields and serving as a windbreak and shade for the cultivation of wheat, ...

Life cycle analysis of wheat and barley crops for bioethanol production in Spain
A Life Cycle Assessment (LCA) of the agricultural production of wheat and barley grain to be used as a raw material for bioethanol production in Spain is performed. The objective of the work presented is to compare the environmental impact of the production of these two alternative raw materials for the production of bioethanol. This study is carried out in the frame of a higher scope study, a ...

Growing Industrial Hemp - Risks and Rewards
In 2013, Colorado became the first state in the US to legalize industrial hemp. The 2014 Farm Bill granted US farmers the right to cultivate hemp in states where production is legal and established hemp pilot research programs nationwide. Industrial hemp is grown for food, feed, fuel, building materials, and more. Traditional hemp, grown for mass market products such as textiles and bioplastics, ...

Toxicity of biosolids‐derived triclosan and triclocarban to six crop species
Biosolids are an important source of nutrients and organic matter, which are necessary for the productive cultivation of crop plants. Biosolids have been found to contain the personal care products, triclosan and triclocarban, at high concentrations relative to other pharmaceuticals and personal care products. The current study investigates whether exposure of six plant species (radish, ...

Grain Yields Starting to Plateau
By Lester R. Brown From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as the principal source of growth in world grain ...

Impacts of climate change on irrigation water requirements for rice–wheat cultivation in Bagmati River Basin, Nepal
This study highlights the spatial and temporal impacts of climate change on rice–wheat cropping systems, focusing on irrigation water requirement (IWR) in the Bagmati River Basin of Nepal. The outputs from a general circulation model (HadCM3) for two selected scenarios (A2 and B2) of IPCC and for three time periods (2020s, 2050s, and 2080s) have been downscaled and compared to a baseline ...

2 Series PTO Shaft - Replaces Bondioli & Pavesi PTO Shaft
The PTO shaft 2 Series is one of the types of power transmission devices that transfers energy from an agricultural tractor or another source to an engineered implement or attachment. It's an upgrade of the 1 Series PTO shaft, made for applications where greater power and torque are needed. It is the 2 Series PTO shaft comes with an increased diameter and higher torque capacity when compared to ...

A Saline Duper Wheat that Tolerates Higher Salt Concentrations!
In the past few decades, agricultural land has been largely lost, and increased salinity in soils around the world has received much attention. Nowadays, nearly 8% of the world's arable land can no longer be used for crop cultivation due to salt pollution, and more than half of the world's countries are affected. Wheat is the second largest grain grown after corn and grows more on Earth than any ...

Losing Soil
In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

Making sustainable intensification work on sound evidence
Assessing the real-world impact of new agronomic practices depends on good economic studies, says David Spielman. A new narrative is slowly taking hold of today's collective thinking about productivity, growth and poverty reduction in developing-country agriculture: the concept of sustainable intensification. Sustainable intensification hinges primarily on practices and technologies that help ...

Variable Rate Seeding with Drone Imagery
Getting a good crop canopy across the entire field is important for better crop quality and higher yield. One way of achieving this is by varying the amount of seeds. In recent years more and more farmers have started using variable-rate technology. By coupling the tractor’s GPS equipment with the seed drill, the seed amount can be varied across the field based on a predetermined plan. The ...

Seedbed preparation
Timing and weather, as well as kit, are key parts of seedbed preparation on the min-till system. The search for lower establishment costs has led one Warwickshire grower to ditch the plough and opt for a min-till approach that offers the capability to direct drill too. Geoff Ashcroft looks at the system in use. The ability to direct drill cereals does hold a certain appeal, particularly when ...

Ancient roots of wheat virus resistance
The DNA sequence of a gene responsible for resistance to a devastating virus in wheat has been discovered, providing important clues for managing more resistant crops and maintaining a healthy food supply. Wheat crops in the Americas, Asia, Europe, and Africa are regularly damaged by wheat yellow mosaic virus (WYMV), and there is a high demand for wheat varieties or cultivars that are resistant ...

Many Countries Reaching Diminishing Returns in Fertilizer Use
When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It was not until the ...

5 ways drones can help farmers in spring
Throughout the whole growing season, drone images can be a good tool for farmers to make their work more effective. Already in spring, drones can be used in the field to help answer important questions: How was the establishment of winter crops and how has the winter affected the crops? Where do I need to reduce or increase the seed rate next time? Should I change the time of fertilization? Where ...

Large-scale irrigation - Understanding energy-water-food connections
Original story at MIT News An MIT team is providing new understanding of the growing interconnections among three critical resources: energy, water and food. The work focuses on Pakistan's Indus Basin, where irrigation water is increasingly pumped from underground, a practice that is intensifying a preexisting shortage of energy. Using new and existing data plus statistical models, the ...
