The United Nations’ and Agriculture Organization predicts that by 2050 the world will need to produce 70 percent more food than it does currently. Along with improving food storage and transport, increasing crop yields is seen as a primary solution. Salinity is one the major environmental stresses affecting crop production, particularly in arid and semi-arid areas. Most of the vegetable crops are salt sensitive, growing poorly in salinized soils due to the accumulation of toxic ions from prolonged irrigation regimes. A meaningful approach to increase crop yield and counteract salt stress would be the use of protein hydrolysate-based biostimulants, which are gaining interest worldwide. Nowadays, more than 90% of the protein hydrolysates market in agriculture is based on products obtained through chemical hydrolysis of proteins from animal origin. The production and use of new vegetable derived-protein hydrolysates with high plant biostimulant activity has become the focus of much research interest due to their lack of plant phytotoxicity, absence of degraded or biologically inactive amino acids or compatibility in the production of food for vegetarians. The commercial partner, Deltagen UK, aims to commercialise protein hydrolysate biostimulants with superior salinity inducing tolerance. The aim of this research is the development of an innovative system to produce protein hydrolysates from the defatted by product meals of flax, lentil and sesame seeds with the ability to biostimulate plant tolerance to salt stress. Novel protein hydrolysates will be produced using a cocktail of suitable proteases, they will be applied to tomato plants (cv. Micro-Tom) in a controlled growth room under salt stress conditions. Treatments will be assessed by comparing classic phenotypical parameters. Plant tissue will also be saved in order to assess other biochemical and molecular parameters such as stress related proteins and osmoprotectant metabolites.
The beginning of 21st century is marked by global scarcity of water resources, environmental pollution and increased salinization of soil and water. An increasing human population and reduction in land available for cultivation are two threats for agricultural sustainability. It has been estimated that worldwide 20% of total cultivated and 33% of irrigated agricultural lands are afflicted by high salinity. It has been projected that more than 50% of the arable land would be salinized by the year 2050. Use of optimized farm management practices such as shifting crop rotation or better irrigation systems can ameliorate yield reduction under salinity stress. However, its implementation is often limited because of cost and availability of good water quality. Several salt-tolerant varieties have been released, the overall progress of traditional breeding has been slow and has not been successful, as only few major determinant genetic traits of salt tolerance have been identified. The utilisation of agro-food processing wastes to generate value added products is an extremely convincing argument as it makes commercial and environmental sense. In addition, it is an excellent, demonstrable example of the European circular economy in action, a key objective of the H2020 research programme, turning waste into value and ultimately food for a growing population.
Three process variables will be studied in order to obtain the maximum degradation of seed proteins: incubation time, temperature and the initial concentration of meal protein. The Response Surface Methodology (RSM) will be used to reduce the cost and duration of experiments and allow for the observation of any interacting factors in the final process response. Amino acid and monosaccharide composition will be determined by sensitive high performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) according previous bibliography. Molecular weight distribution of protein hydrolysates will be characterized by protein electrophoresis (SDS-PAGE) and high performance size exclusion chromatography (HPSEC). The plant trials will involve 2 separate sets of experiments under unstressed and salt-stressed conditions respectively. Experiments will be carried out in a growth room with different concentration rates of different protein hydrolysates and the tomato variety Micro-Tom will be used. This extensive factorial experiment will be assessed by fruit yield, fruit quality, chlorophyll (SPAD measurement), MDH content (cell membrane integrity) and levels of protective compounds (proline and soluble carbohydrates). The presence of stress proteins such as HSPs will be determined using immunoblotting techniques (Western blot). RT-qPCR is another advanced laboratory technique that will be emp
This course will provide you with an in-depth specialisation in organic farming and food production systems and it is currently the only specialised MSc in organic and ecological farming in England. You will learn and test the latest approaches in the integrated delivery of soil, crop and livestock, and food supply chain management.
Through a combination of lectures, field trips, seminars, practical classes and research projects you will develop advanced knowledge and skills in:
-Managing organic farming and food production units or businesses in different macroclimatic, agronomic and market contexts
-Agronomic approaches used in organic/biological/ecological/sustainable food production systems
-Underlying principles and standards of organic/biological/ecological/sustainable food production, processing and retailing/marketing systems
-Applied and strategic research underpinning the development of organic and other sustainable farming and food production systems
-A wide range of analytical laboratory methods
You will have the opportunity to attend a 10-day field trip as part of the module on Mediterranean perennial crop production systems in Crete, Greece. The trip is organised in collaboration with ecological farming experts from the Greek National Science Foundation (NAGREF).
As part of your studies you will also undertake a major project, similar to one you might experience in the workplace. You will be supported through training in designing and delivering a laboratory project or field-based investigation. You will collect, analyse and interpret data to produce a thesis reporting your investigation and results in a critical manner.
This research project and thesis may be undertaken at the University, in industry, in Crete as part of existing Nafferton Ecological Farming Group research and development projects, or in another country.
You will benefit from being taught by lecturers who are industry experienced and research active. Our research in integrated agricultural production focuses on soil science, plant science and ecology, spanning a range of scales from: pot – plot – farm – landscape.
Strategic research embraces work on:
Applied research addresses issues of:
-Climate change mitigation (including biofuels)
-Ecological (organic) farming systems
-Low-input crop systems
Professor Carlo Leifert is the Degree Programme Director for MSc in Organic Farming and Food Production Systems. Carlo is a member of the Food Security Network in the Newcastle Institute for Research on Sustainability (NIReS) and is part of the Nafferton Ecological Farming Group (NEFG). He currently manages EU and DEFRA funded projects focused on improving resource efficiency, productivity and food quality and safety in organic and 'low input' crop and livestock production systems.
The course is taught in a block format with a six-week block and then two-week teaching blocks.
You will be taught through:
-Practical and field classes
-Small group discussions
You will be expected to undertake independent study outside of these structured sessions. Your knowledge and understanding will be assessed through written examinations, coursework, presentations and your final major project.
You can also study through the Credit Accumulation Transfer Scheme (CATS). This allows us to award postgraduate level qualifications using credit-bearing stand-alone modules as 'building blocks' towards a qualification. This means that the credits from modules undertaken within a five-year period can be 'banked' towards the award of a qualification.
Our multi-purpose farms provide demonstration facilities for teaching purposes and land-based research facilities (especially in the area of organic production). They are both viable farming businesses.
Cockle Park Farm is a 262ha mixed farm facility that includes the Palace Leas Plots hay meadow experiment and a new anaerobic digestion plant that will generate heat, electricity and digestate - an organic fertiliser - from pig and cattle manure.
Nafferton Farm is a 300ha farm with two main farm units covering conventional and organic farming systems. The two systems are primarily focussed upon dairying and arable cropping.
Both also operate beef production enterprises as a by-product of their dairy enterprises, although the organic system is unique in maintaining a small-scale potato and vegetable production enterprise.
Our modern laboratories provide important teaching and research environments and are equipped with analytical equipment such as High-Performance Liquid Chromatography (HPLCs), GCs, CNS analyser (Carbon and Nitrogen analysis), centrifuges, spectrophotometers and molecular biology equipment. Our specialist research facilities include:
We operate closely with other schools, institutes and the University's central scientific facilities for access to more specialist analytical services.
For work with human subjects we use a purpose built Clinical Research Facility which is situated in the Royal Victoria Infirmary teaching hospital and is managed jointly by us and the Newcastle upon Tyne Hospitals NHS Foundation Trust.
The NU-Food Food and Consumer Research Facility has undergone a £700,000 refurbishment and now boasts a culinary training suite, a sensory laboratory and food handling facility, all supported by multi-functional rooms and a reception.
