I have recently added to a discussion about my fuchsia plants that were out in the first very cold few days in 2022. They are usually out during the winter but looked as if they had died. So, I put them in a porch and gave them words of encouragement. And I have congratulated them about their green shoots.

I then added a piece to another RG discussion asking if any members either talk to their plants or feel that it is helpful (to the plants as well as the RG member!)

The Royal Horticultural Society has done research into this:

and there are other positive thoughts on the subject, just to mention a few:

I would be really interested in your thoughts and will pass the messages on to the fuchsia!

I wondered if tomatoes could grow in a closed container last summer. So I put some soil in a water bottle and a few tomato seeds and coriander seeds on top of the soil and then covered the seeds with a very thin layer of soil. Afterward, I watered the soil very little, closed the bottle tightly, and placed it on the window side. I didn't touch the bottle again, but after a while, I saw that first lichen-like structures formed in the soil, secondly Elodea-like organisms emerged, and a plant had grown.

How is this whole process possible without anything but oxygen, regular watering, and seeds? And what could be those plants which are growing inside the bottle?

Res. Sir/ Madam,

I am working as Scientist (Horticulture) and my research focus is improvement of tropical and semi arid fruits. I am also interested in working out role of nutrients in fruit based cropping systems.

Looking for collaborators from the field of Genetics and Plant Breeding, Horticulture, Agricultural Statistics, Soil Science and Agronomy.

Currently working on Genetic analysis for fruit traits in Jamun (Indian Blackberry).

I am wanting to learn more about the R/FR ratio relative to the PSS.

Hi everyone!

I project to mesure levels of various nutricional parameter in pepper fruits. Looking up in the literature, I found out the research article of Nagata and Yamashita (1992), in which a spectrophotometric method for analysis of chlorophyll and carotene in fruits is described.

I think that the information provided by Nagata and Yamashita (1992) could be very useful for our project. Even though, this paper is not written in English, but in Japanese (a language that, unfortunately, I do not understand).

As it is a highly cited study (1112 citations in Google Scholar, many of them from non-Japanese authors), I suspect that the procedure of Nagata and Yamashita (1992) must be detailed in English somewhere.

I would be grateful if someone could give me some light about this.

Thanks in advance!

In kang kong, plants are raised both from seeds or cuttings although plants raised from seed is the normal practice. But it has been observed that not all the stem cuttings of kang kong used for propagation exhibited desired performance i.e. produced healthier plants. Only one or two specific nodes exhibited better performance.

Within a project about geographical traceability of horticultural products, we would like to apply classification models to our data set (e.g. LDA) to predict if it is possible to correctly classify samples according to their origin and based on the results of 20-25 different chemical variables.

We identified 5 cultivation areas and selected 41 orchards (experimental units) in total. In each orchard, 10 samples were collected (each sample from a different tree). The samples were analyzed separately. So, at the end, we have the results for 410 samples.

The question is: the 10 samples per orchard have to be considered pseudoreplicates since they belong to the same experimental unit (even if collected from indepedent trees)? Should the LDA be performed considering 41 replicates (the 41 orchards, taking the average of the 10 samples) or should we run it for the whole dataset?

Thank you for your help.

Light (PAR) is necessary for photosynthesis. But how to calculate the minimum amount of sunlight necessary for the expected growth of a crop( no crop loss ) and beyond this PAR the plant is considered to be subjected to low light stress?

Is there any paper of systematic protocol?

Let's face it, cultivation in greenhouse is often afflicted by pests, from powdery mildew to aphids.

We still use plants that don't appear affected, but they're still subjected to phytosanitary treatment and there might be effects that are not noticeable or considered.

How important is to mention phytosanitary treatments in publications? Should we always plan our experimental design with controls for possible effects of phytosanitary treatments?

Dear Researchers

Kindly suggest me the potent chemicals, which can be used in depredatory bird management in horticultural and agricultural crops

Dear,

Researcher,

I am Dr Tanmay Kumar Koley, presently doing research on bioactive molecules from horticultural crops. I have some rare plant material which have high starch content. I want to study some of the properties such as X-ray diffraction, thermal properties (Differential Scanning Calorimeter), dynamic light scattering (DLS), Fourier-transform infrared (FTIR) spectroscopy etc. of that starchy plant sample. If you have these facilities or can suggest where I can avail these facilities it will be helpful for me.

Your contribution will be appreciated as co-author.

Thank you

Mangoes are harvested in June-July under humid conditions and high temperature (more than 40 degree celsius). Due to the lack of cold storage and cold chain in Nepal, farmers are not able to reach urban markets. I am looking to understand if using ethylene absorber sachets can enable them to reach distant markets.

I would say most invasive alien plants are synanthropic species in that they were introduced intentionally for horticulture or other cultivation purposes, or they were unintentionally introduced but are 'weeds' that thrive in disturbed areas and associated with cultivation at some point. I'm struggling to think of good examples of non-synanthropic invasive plants, but I can think of animal examples.

Can anyone please provide me the NBPGR minimal descriptors of different Horticultural crops?

I saw very different works during my researches. For some people, a species can be considered exotic in Europe when its native range is quite far from the continent, i.e. North America. Others prefer to consider it exotic when the native range falls in a different biogeographical region, i.e. a species from the Mediterranean Basin found in Germany.

If we are talking about phytophagous arthropods, things get worse, because their movement usually depends on their host plants, and therefore, on their introduction in different areas for gardening and horticulture purposes.

I wonder that if I would know the mathematical relationship to find the root propagation of a fibrous rooted coconut tree (Coccus nucifera) or a tap rooted mango tree (Mangifera indica) then I can excavate the entire plant safely and install it in a better place if I need to have a building construction where already a tree was planted. This would be the most sustainable approach considering the human requirements and ecosystem wellbeing.

Silicon is a multi talented element carrying several different benefits for horticultural plants. Previous reports revealed that using calcium or sodium silicate as a foliar application is increasing the photosynthetic rate. However, it isn't dissolved in water. How can I use it ?

Dear sir/ madam,

Please mention any distributor/ dealer in INDIA who can provide one RHS colour chart for Department of Horticulture, CUTM. Any contact number/ email id if you are having, please share with me.

Thanks in advance.

Hi

I’m looking for free online conferences on plant science / food and nutrition / agriculture / horticulture etc.

Hi,

I’m a PhD student. I’m looking for a short term scholarship for PhD students.

The aim of it is to prepare a common publication (selenium, zinc, bioactive compounds in plants).

A Journal publishes articles about horticultural related researches with no publication fee, peer-reviewed and indexed in Scopus.

I am trying to design an agricultural and horticultural calendar for Karbi Anglong and Dima Hasao districts of Assam, India. What are the steps that I should begin with?

Hello everyone,

We are planning to study how plant growth promoting bacteria are affecting various plants (eg. wheat, barley, etc.). We would like to coat the seeds with bacteria. We prefer film coating. I can't find any proportions of seed, inoculum, carrier materials and sticking agents.

Could you please share the recipe you are using for your research? We prefer using cellulose or lime as a carrier material.

Thank you in advance.

we all know that it is our traditional practice which we are performing in any problem in our kitchen garden to farm level is it good to apply or not, how it is good or what are its effects.

farmers ,agricultural sectors workers are always ignored ,although we are only because of them,what the reason behind this .....................

In my personal experience I have find the higher rate of sprouting when fresh cow dung is applied on the top side of cutting what might be its reason.

Most of the farmers are rearing honey bees in both field and horticultural crops. But whcih crops we will get the high & good quality of honey.

People in our village have some belief of controlling some pest and disease, they apply salt in the rice field, what is its scientific importance.

Journals related to fruit based Agroforestry and horticulture basically for a review paper.

The rot starts from the root region being completely dark first then pulpy-like appearance.

Is there any relationship BER with water stress except Ca defficiency ?

The formula for the Seedling vigour index is given as:

Kumar, B., Verma, S. K., Ram, G., & Singh, H. P. (2012). Temperature relations for seed germination potential and seedling vigor in Palmarosa (Cymbopogon martinii). Journal of Crop Improvement, 26(6), 791-801.

But, we, in our research did the thinning out on the 7th day and raised only one model plant per replication (of particular treatment) for the next 9 days i.e. 16 DAS. We did destructive sampling of the model plants on the 16th day. So we don't have the length and weight data of the sample plants on 7th day but only on the 16th day.

Shall we proceed to calculate the Seedling vigour index of thinned out seedlings only (on day 7th)? Or combine both data directly (of 7th and 16th day)?

Unfortunately, we came across tragedy in our personal apple garden and a few of our trees have majorly infected by Fire Blight pathogenic agent. I have attached a few photos of infected trees, I think there is a relationship between the white stains on the bark of the tree and diseases outbreak. I think the more white spots there are, the more the tree is exposed to the disease. However, this is my experimental understanding and I have no academic expertise in this field. That disease has appeared only on the red apple trees.  

I would be very happy if you put me in the right pass and let me know how I can overcome that disease. 

Sincerely yours 

Bagher

Excuse me, professor, i'd like to know the ambient CO2 concentration (ppm). Hope you don't mind to tell me. Thank you.

I'm a horticulture student and I have difficulty in contructing what topic will I study. I want to focus more in growth and production

My farm location has 800 mm rainfall. Soil is deep black soil. Ph:8-8.5 Turmeric is a 9 months crop. I have no drip facility. And I can give irrigation once in every month from November to March. Sowing is done in July last week. Another 600 mm rainfall is expected during August to November, max. being in August, September and October, with ~30, 50, 20 ratio. If I use mulch I cant use surface irrigation. And rainfall will be probably lost through surface runoff. However, mulch conserves soil moisture, keeps water losses away from weeds and minimizes weed load, reduces soil temperatures. What is the possible production scenario?

There is sweepage of the white fussy outcome of liquid with foul smell and destroying plant completely it is in the particular plant since few days, what is this and how it can be controlled?

agriculture, soil, mycorrhizal fungi, biology

Is there any post emergence weedicide to control nutsedges (Cyperus rotundus) in cotton without using any shield or perventive nozel? Any weedicide which can kill nutsedge but doesnt harm cotton crop?

We are feeling a shortage of land and less efficiency of resource used how it will be the concept of Multiple Layer High-Density Farming (MLHDF).

As our general practice in the rice field show increase in yield, and more vegetative growth, what are the constraints and prospects for its wide application and adaptation in rice, horticultural crops, and many more?

We are trying to estimate curcumin content in Turmeric genotypes. Rhizomes are cut in pieces and oven dried at 60 o C. Certain genotypes retained the original colour on cut surfaces and others changed to brown to dark brown on cut surfaces. What is the reason? Does polyphenol play a role ? What about other factors? We are sure that it is not due to excessive heat, as we have seen this even under lower temperatures.

The yield of plants is found to be increased with the conservation of perennial to annual plants what are the processes, advantages, and disadvantages?

In some places, it is common to grow high cash crops (usually horticultural crops) even if there is a surplus of its production in such places. The common reasons for that are it is more efficient in using water and more important it has high cash return. On the other hand, in most of the time we can find in the same places a huge shortage in the production of strategic crops (usually field crops). Usually it is justified that, high cash crops can be exported for much higher prices and in return strategic crops can be imported. However, with the ongoing scarcity of water which forced some countries to pan the exportation of some crops and some other countries are using some of those crops as a pressuring tools on other countries, in addition to the conflicts that come up making trade unstable,

Kindly share your opinion.

The North eastern region of India (26.3 m ha geographical area) is having an unique geographical and environmental characteristics with very high annual rainfall, no or meagre rain during November to March, soil acidity, P fixation, soil, nutrient and biodiversity loss due to primitive farming practices like along the slope cultivation, shifting cultivation, lack of soil and water conservation measures and so on. The major challenge is sustaining food security and at the same time conserve natural resources. Drought, floods, hailstorms, cyclone, land slide, earthquake etc are major natural disasters in the region which farmers/people face every year. By 2050, about 30% deficiency in food grains is projected. Oilseed and pulses sector deficiency remain very high. Same is the situation in fish, milk, meat, eggs and so on. Only Horticulture sector is able to meet the requirement and provide a reasonable surplus, thus, there is opportunity for processing and value addition to enhance income and employment. Massive infrastructure and investment is needed for meeting seed and planting materials requirement for crop, animal and fishery sector. Mechanization is still one of the lowest in the region and restricted mostly to rice cultivation that too for field preparation, threshing etc. Light weight automated machines are required for field preparation, planting, intercultural operations and so on. There are large number of farm machines available in various parts of the country many of them may be suitable for the region, with only a little modification. Conservation agriculture is the real need of the region with principle not restricted only to three but beyond like agroforestry, integrated farming system, efficient water use, integrated nutrient management and so on. Rain water harvesting and its efficient utilization, acid soil amelioration, and sustaining soil fertility through integrated nutrient management holds key for achieving Sustainable Development Goal in the region. Addressing shifting cultivation through improved management approaches and farmers participation is also the focus at present. Trans boundary pests (insects and diseases)-their survey and surveillance and adequate management is the major thrust for protecting crop and animal. Addressing marketing and socio-economic issues are also important aspect of agricultural development of the region. Look forward suggestions for devising effective agricultural plan for sustainable hill agriculture. Collaboration and partnership in research is welcome to achieve the goal of self sufficiency and resilience in farming.

I’m working on the use of stable isotope ratios in traceability studies of horticultural products. Based on literature and previous studies, I can use any tree part for the analysis when it comes to Sr isotope ratios. However, things change considering H and O, as their isotope ratio may vary considering different classes of organic compounds in plant materials, due to differences in the metabolic pathways of each class (to simplify, let’s consider that all the material was synthetized during the same time frame, e.g. same growing season).

So, I would like to know your opinions about the following points:

1. If I analyze δ2H and δ18O in different tree parts grown in the same period (e.g. shoots, leaves, fruits analyzed as bulk sample), should I expect that the different proportion among classes of organic compounds in each part can lead to a significant difference in their δ2H and δ18O?

2. Analyzing a specific class of organic compounds (after extraction) instead of the bulk sample, should I get the same value in all the different tree parts?

I found several papers discussing this specific topic but related to C and N isotope ratios, can you suggest me any papers related to H and O? Many thanks.

In many conservatories around the world, as well as in many organic-farms, insecticidal soaps (potassium salts of fatty acids) are widely used to combat aphids, mealybugs, mites etc. They are considered safe to mammalians and are prioritized instead of chemicals.

Very little to no information can actually be found whether the soaps may be toxic to amphibians. Can anyone help us on this matter? An eductaed guess would tell me that the thin film created by the sopa on aquatic enviroment as well as, presumably, on the skin of the amphibians would cause significan damage.

Many thanks!

A Neem tree palnt is a tree plant has the tendency of growing very tall under favorable climatic conditions. Its tap-rooting system enhance its capability of survival through photosynthesis.

What improvements to crop varieties can be made to ensure that emissions of greenhouse gases from agriculture and horticulture are significantly reduced?

Knowing the overall hazardous effect of chemical farming too we are not getting away to organic farming, even on a small scale or on a large scale in too so what will be the challenge during the approaches or organic farming. Thank you.

We all know the role of microbes its miniature of the miracle how it can be , used in revolutionizing science in various fields.

I'm looking for rootstock for papaya grafting. Is there anyone have any experience?
