We are open for collaboration in the horizon of 2020 programme.
I am working in the Department of Fruit and Vegetable Product Technology. We have experience with modern techniques of fruit and vegetables preservation: high pressure processing, continuous microwave heating, supercritical carbon dioxide as well as access to these equipment. We are also interesting in pulsed electric fields and high pressure homogenization techniques. If you intends to take to coordinate the grant in Horizon 2020 program as well as you are looking for teams or people to work together we are open to all suggestions. We have a well-equipped technological laboratory with laboratory and pilot plant equipment as well as an accredited physicochemical and microbiological laboratory.
In some parts of Africa some land races of watermelon used as vegetable. though i have very little information about it. Another melon (musk melon) often used as vegetable in immature stages. in my area watermelon is not a major crop. only in some river beds it cultivated in spring-summer seasons. so i like to know if there is a possibility to use immature fruits of watermelon as vegetable. please give some idea.
Trying to think of a substrate material that makes sense in the context of my study - in a field of vegetable production.
Please help about get the latest book on the vegetable production. With thanks
We have a cucumber wilt that is spreading in greenhouses.
I have done some search online and found similar cases in the area (I posted the photos that is similar to the case we have).
Please share your opinion.
Thank you,

Vegetables (and fruits) are key elements in human alimentation, with benefits on health for example. At the ame time, they are often the results of intensified systems, heavily relying on chemical inputs to maintain soil fertility and to protect crops. Promoting agroecological transitions in such systems is therefore a real concern.
Food systems are one of the tools that public policies or local policies can use to promote these agrocecological transitions in vegetable production.
It is therefore clear that vegetable production and food systems are linked. I would like to clarify all these links, and all their implications, not only in terms of sociological quesitons, but also economic, agronomic, on land-use patterns, on culture and culinary traditions...
My first step is then to get a idea of who is interested by all or part of this topic (I also am doing a litterature survey, of course!).
Thanks for getting in touch, my feeling is that there are not so many forces on such topic, and we can gain by sharing our eforts.
I am trying to find out the best preventive measures to reduce the post harvest losses during storage of onion.
I have read research papers related to PHL. If any of you are working on post harvest losses in onion, please help me.
Dear all,
I have a question regarding ways to reduce soil phosphorus levels in a soil with excessive soil P levels. There has been vegetable production in the field for quite some years, fertilised with compost and chicken manure (high P sources). The soil P levels range from 200 to 400 ppm (Mehlich III). The calcium saturation is also high. This field is in a cold temperate climate (southern Norway). As P doesn´t leach, the only way is to remove P by crop removal (and no more added P). So my questions are:
- Which crop plants will take up and remove most P from the soil? The crops will be exported off the land.
- Which methods can be applied to reduce micronutrient (Zn, Fe etc) lockup so the crop plants still thrive?
Thank you very much in advance!
Hello everybody,
I have to quantify the nitrates amount in vegetables and I would like to validate my data with a reference material for nitrate content in vegetables. But I cannot find a supplier. Can anybody suggest me where/how to find it?

Can anyone refer me to articles that deals with diallel analysis of postharvest traits (during storage) in any horticultural crop
We are currently building an aeroponic system for cultivation of various vegetables.
However, we seem to be stuck at the choice of an appropriate type of spray nozzle head. Ideally, the droplet size would be about 50 µm and it should be sprayed in an angle as wide as possible.
I've tried several companies specialized in distribution of these nozzle heads, but none of them seem to have an appropriate one.
Am I being to strict?
Does anybody have a suggestion? Or better yet, could you share which nozzle heads you use?
Good evening respected teachers/scholar/researcher, I hope you are fine and doing well, I am Ph. D student in china, working on current project "Sustainable vegetable production in china" in College of Horticulture, Northwest A&F University, China. I analysed soil microbial diversity by Illumina MiSeq platform. i have data in figure form, some of them i couldn't understand How to interpret it well especially "Heat map analysis" ? my capabilities are very limited in soil bio diversity and microbial ecology. So i need assistance belong to bioinformatic or soil microbial ecology experts for my figure illustration? Details about these figures are in attached file. I really thankful if someone help me in this regard.
Please provide data on the history of the Ziban region and its palm groves ?
Hydroponic systems currently employ normalized, sterile, water soluble fertilizer solutions which are highly effective for growing high quality crops quickly. However, these mined salts are not sustainable and must be replaced with organic sources. As we know, plants do not utilize organic compounds in the root zones for nutrition, and insects and microorganisms must break these compounds down to usable inorganic plant nutrients. Would it be preferable to create a process by which consistent compost material is harvested of its degradation products for use in hydroponics, or would it be best to employ fertilizers with mixed organic and inorganic nutrients to a system pre-innoculated with beneficial mycorrhizae and rhizobacteria? Research has shown that hydroponic cultivation can impart higher nutritional value to edible crops when compared to organic and conventional cultivation. However, it has also shown that aquaponic cultivation supplemented with inorganic nutrients performs even better on yield. Could this be because soluble nutrients are supplied alongside insoluble ones in a living system? Thank you in advance for your thoughts on the matter.
I conducted a variety trial of tomato. However, due to early frost period, I decided to harvest all mature fruits and cut the plants to determine plant biomass while there was some premature fruits (green fruits) which was also weighted separately from plant biomass. I am wondering if it makes sense to include these premature fruits as yield? The proportion of the remaining fruits was about from 10-20% comparing to the harvested mature fruits.
Dear all. I'm following a procedure in order to use AOM (Azoxymethane) in a mice colorectal cancer inducing. I've determined I need only 20 microliters from a glass container of 100 microliters of commercial AOM. Can I only use 20 microliters and storage 80 microliters in a sterile glass container? Or maybe the remaining AOM will evaporate and concentrate? What is the best choice in order to preserve the remaining 80 microliters (temperature, diluting, etc.). Thanks in advance.
Silencing CWIN expression in tomato resulted in increased fruit abortion, and reduced fruit size and seed number per plant (Zanor et al., 2009). An article from a team led by Dr. Yong Ling Ruan in cotton says that silencing of VIN genes led to fiberless seed phenotype, but not the viability and the development of the seed set.
I am particularly interested in the use of Paclobutrazol in South Africa.
Artichocke's irrigation performance need a comparison with theoretical requirements. What kind of data are necessary for this ?
The inflorescence is too frigile that it may brake, while handling, esp when we attempted hot water treatment.
If we cut the top 1/3rd portion of the flower for emasculation, the flower turns brown and dries up.
Pl let me know the methods available and how to go about standardising the procedure for artificial crossing
Dear Sir/Madam,
I am studying about a small-scale units (processing units) of drying vegetable and fruits. I would like you to inform me if there are any articles about layout of a building for drying vegetables and fruits (e.g. inspect, wash, peel and dry).
I would be grateful if you could reply as soon as possible.
Like number of producers, processors, wholesalers and retailers? Either for meat, fruit, cereals or vegetables. Thanks
Hi,
I am looking for regulations on nitrite limits in vegetables. I have found nitrate limits but nothing on nitrite. Does it mean there are not allowed any nitrites in vegetable products?

A concept of stress has a bit of controversy when we move from species to vegetation. Environmental stress means that overall vegetation productivity is reduced for whatever cause (more limited resources, presence of toxic elements, reduced or imbalanced water/energy supply). But species behave in a mixed way: while most species respond as expected to the stress and reduce their productivity, some species are so specialized that grow better under such stressful conditions [example – alpine Rhododendrons (Rh. caucasica) – a cold-adapted species from high elevations that cannot be grown in lowlands even under garden experiments]. Does anybody know any similar examples re light? Any examples of shade-specialists who die if the shade is removed?
I'm working with a college group looking for ways to modify the vigor of tomatoe plants using grafting on other Solanaceae rootstock. We would all be grateful to get some research results on this.

Hi
I hope you have a good time.
I wonder if someone could answer me:
How we can decrease the ethylene level in tomato? Can we use of decreasing of the ethylene level in plants?
Thanks a million.
Green sand (K feldspar?) is considered a natural source of potassium (K) and is acceptable to organic farming. However, its K ( about 5 - 6%) is released very slowly. Are there any treatments/amendments that could increase/speed up its K release?
Legume-cereal cover crop mixes are often promoted because they combine the ability of legumes to add atmospheric nitrogen to the system through biological fixation in root nodules, and the ability of the cereals to scavenge nitrogen that is prone to leaching during the winter. Efficient nitrogen use is especially pertinent in organic systems because the cost per unit of nitrogen in organic fertilizers is relatively high. Cover crops can provide important ecosystem services (soil improvement, nutrient cycling, weed suppression, etc.) and therefore are crucial in sustainable agriculture. An important question to ask is whether or not legume-cereal mixtures are a good fit in tillage-intensive organic vegetable production systems that are common in California? I addressed this question in a presentation at the 2014 American Society of Agronomy conference based on my experience with short-term and long-term research on organic vegetable studies conducted in the major region for high-value vegetable production in California. See YouTube link below. This research has shown that the performance (i.e., biomass production, ground cover, weed suppression, potential nitrogen fixation) of cover crop mixtures can vary markedly between and within farms based on soil type, land history, cover crop management (i.e., seeding rate, planting method, planting date, mixture composition), and climate (i.e., winter rainfall and temperature). I'd love to hear what other researchers think about the complexity of integrating these mixtures into vegetable production systems.
We need to provide a good variety of turmeric for planting them in a greenhouse.
In Fiji we found fertility variance even in small areas. Farmers are spending a lot to cultivate vegetable and we found many patches of poor growth. To give a solution I am looking for some equipment which can give a rough idea about the soil fertility in the farmers field.
For a hydroponics research lab. I would ideally have a chart that provided me info on if cucumbers needed more nitrogen than tomatoes, etc. for every relevant vegetable. Hydroponics have proven most successful with small root system vegetables (salad greens, herbs). I want to optimize nutrient intake in each stage of vegetable growth.
I'm working with ADM1 model for dynamic simulation of anaerobic treatment of vegetable wastes. I have uncertainty about mass transfer in this model. Is anyone interested in keeping in touch?
Biotechnology has emerged as a modern tool for improvement of crop plants since last 30 years. Even then there is not even a single commercially important variety which is developed by using biotechnological tools eg. somatic hybrids, cybrids, GE variety in India. what are the possible reasons responsible for failure of this technology. Why this work is limited only to laboratory and research papers? Why even after spending big amounts on this technology it is not giving desired results in favour of poor farmers? Is it worthless? Please do share your ideas.
