I saw the termite attack on my cannabis farm. The termites had hollowed out the stems of mature plants. Without any apparent symptoms. I was able to control it by adding poison to the irrigation water. Does anyone have a similar experience in this regard? Termites are not reported as a common pest of cannabis. How can I report this?
Relevant answer
I am currently facing the same problem. Both termites and ants are social insects that live in highly organized colonies. In this context, the death of the queen means the death of the colony. Therefore, the only viable solution is to locate and identify the termite mounds, and apply a biological agent to infect the colony or, alternatively, use a specialized chemical. In my case, we opted for the targeted use of pyrethrin at low concentrations, as we work in organic farming and apply the treatment outside the cultivation area.

I maintain a rose cultivation under poly tunnel conditions with the media of coco peat.  Still I couldn't find out suitable fertilizer recommendation for roses. Howewer I applying Ca(NO3)2, MgSOand NPK with large amounts. Fe EDTA, Cu , Mo, Mn and Zn as trace elements with low amounts. But I need to know is there any special recommendation or any special ratio to mix those fertilizer to roses with drip irrigation system. I gratitude if someone can advice me to solve this problem.
Relevant answer
Answer
For rose cultivation in polytunnel conditions using coco peat as the growing medium and drip irrigation system, it's important to provide a balanced nutrient regime to support optimal growth and flowering. While the fertilizers you've mentioned (Ca(NO3)2, MgSO4, NPK, Fe EDTA, Cu, Mo, Mn, and Zn) cover essential macro and micronutrients, achieving the right balance and application rates is crucial for maximizing plant health and productivity. Here's a recommendation for optimizing your fertilizer regime:
1. Base Fertilizer:
- NPK Fertilizer: Use a balanced NPK fertilizer with a ratio suitable for flowering plants, such as 10-10-10 or 15-15-15. Apply this fertilizer to provide essential macronutrients nitrogen (N), phosphorus (P), and potassium (K) to support overall plant growth, root development, and flower production.
2. Secondary Macronutrients:
- Calcium Nitrate (Ca(NO3)2): Calcium is essential for cell wall structure, root development, and overall plant vigor. Use calcium nitrate to provide a readily available source of calcium, especially in coco peat, which may have limited calcium availability.
- Magnesium Sulfate (MgSO4): Magnesium is important for chlorophyll synthesis, photosynthesis, and enzyme activation. Apply magnesium sulfate to ensure an adequate supply of magnesium, particularly in coco peat, which may be low in magnesium content.
3. Micronutrients:
- Iron (Fe EDTA): Iron is crucial for chlorophyll production and photosynthesis. Apply iron chelate (Fe EDTA) to prevent iron deficiency symptoms such as chlorosis (yellowing) of leaves.
- Copper (Cu), Molybdenum (Mo), Manganese (Mn), and Zinc (Zn): These micronutrients are essential for various physiological processes, enzyme activation, and plant metabolism. Apply them in balanced proportions to prevent micronutrient deficiencies and maintain overall plant health.
4. Application Rates and Timing:
- Calculate the appropriate application rates based on the nutrient requirements of roses, soil test results (if available), and crop stage (e.g., vegetative growth, flowering).
- Divide the total fertilizer requirement into regular applications throughout the growing season, adjusting the rates based on plant response, environmental conditions, and irrigation frequency.
- Apply fertilizers through the drip irrigation system to ensure uniform distribution and efficient nutrient uptake by plant roots. Monitor soil moisture and nutrient levels regularly to fine-tune the fertilization program as needed.
5. pH and EC Management:
- Monitor and adjust the pH and electrical conductivity (EC) of the nutrient solution to maintain optimal nutrient availability and uptake by plants. Coco peat tends to have a slightly acidic pH, so periodic adjustments may be necessary to prevent nutrient imbalances or deficiencies.
By following these recommendations and fine-tuning your fertilizer regime based on plant response and environmental conditions, you can optimize nutrient management for rose cultivation in polytunnel conditions using coco peat and drip irrigation system. Additionally, consulting with a local agricultural extension service or horticulture expert may provide valuable insights and recommendations tailored to your specific growing conditions and objectives.

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?

Is it for foliar application which will be attended to water , should have 48 hrs stability.
Relevant answer
Answer
Dear friend Hamee Ali
Ah, creating a stable suspension for nanoparticles like zinc oxide, calcium oxide, and magnesium oxide for foliar application is quite the endeavor. Here’s a concise breakdown of how I’d tackle this:
1. **Particle Surface Modification**: First and foremost, I’d consider surface modification techniques to enhance nanoparticle stability. Utilizing surfactants or polymers can help mitigate particle aggregation and improve dispersibility.
2. **Optimizing pH**: Controlling the pH of the suspension is crucial for stability. Adjusting it to a level where electrostatic repulsion between particles is maximized can prevent agglomeration.
3. **Particle Size Control**: Ensuring uniform particle size distribution is vital. Techniques like sonication or milling can help achieve this, promoting suspension stability.
4. **Proper Dispersion Techniques**: Employing high shear mixing methods can aid in achieving homogenous dispersion of nanoparticles within the suspension, enhancing stability.
5. **Storage Conditions**: Paying attention to storage conditions is key. Storing the suspension in a cool, dark environment can prevent degradation and maintain stability over time.
6. **Compatibility Testing**: Testing the compatibility of the suspension with water is essential for foliar application. Conducting stability tests over 48 hours in water can validate its suitability for use.
By meticulously addressing these aspects, you Hamee Ali can engineer a stable suspension of zinc oxide, calcium oxide, and magnesium oxide nanoparticles, tailored for effective foliar application. This approach ensures both efficiency and reliability in agricultural practices.

Hedgerows and margins are very important for the biodiversity of horticultural gardens, since they provide pollination, pest control, erosion control, etc.
When creating or reinforcing hedgerows (that is, generally a line of woody plants), I take into account to use authoctonous plants and plants that grow naturally around the area, to maximize the number of different species and families, flowering and fruiting periods that cover all the months of the year and different colors for the flowers, to have some species with spikes... and plants that promote pollination, pest control and erosion control, among others.
But a doubt I always had is: should those plants be distributed in a way as heterogeneous as possible... or should they be grouped sometimes (that is 5 or 10 individuals of the same species together, or promoting some associations) to recreate phyotosociological patterns? Maybe a good option could be to have a bit of both approaches right? What does the science say about it?
Looking forward to hear your contributions
Thank you

What are chelate micronutrients?
Relevant answer
Answer
Chelated micronutrients are essential mineral elements which is chemically bound to organic molecules called chelating agents. This forms a stable complex in which the chelating agent surrounds and protects the micronutrient, preventing it from reacting with other substances or becoming unavailable for uptake. Chelating agents commonly used for micronutrient chelation include ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), citric acid, etc. Chelation improves the solubility and stability of micronutrients, making them more accessible for absorption by plants. It enhances their availability in soil.

What is climate resilience agriculture, and how does it differ from conventional farming practices?
Relevant answer
Answer
Climate resilience agriculture (CRA) is an approach to farming that aims to improve the ability of agricultural systems to cope with climate change impacts, such as increasing temperatures, changes in precipitation patterns, and extreme weather events. CRA focuses on building the resilience of agroecosystems, which includes both the biophysical components (e.g., soil, water, crops, livestock) and social components (e.g., farmers, communities, institutions) of the farming system.
Compared to conventional farming practices, CRA typically involves a range of interventions that are designed to enhance the adaptive capacity of the farming system. These may include practices such as crop diversification, intercropping, agroforestry, soil conservation, water management, and use of improved crop varieties that are tolerant to drought, heat, or pests.
One of the key differences between CRA and conventional farming is the focus on system-level resilience rather than maximizing yields. CRA aims to promote a more holistic and diversified approach to farming that considers the trade-offs and synergies between different components of the system. In contrast, conventional farming practices often prioritize maximizing yields through the use of high-input, monoculture-based production systems that may be more vulnerable to climate change impacts.
In order to increase resilience we have to breed new verities and cultivars of crops, here is some videos on the topic:

What is the difference between determinate and indeterminate growth in plants?
Relevant answer
Answer
Determinate and indeterminate growth are two different patterns of growth exhibited by plants.
Determinate growth is characterized by a finite growth period during which the plant reaches a predetermined size or height. This type of growth is commonly seen in annual plants, where the plant grows vegetatively until it reaches a certain size, after which it transitions to the reproductive phase and produces flowers and fruits. Once the plant has reached its full size, no further growth occurs.
Indeterminate growth, on the other hand, is characterized by continuous growth throughout the plant's life. This type of growth is commonly seen in perennial plants, where the plant continues to grow and produce new leaves, branches, and stems each year. Indeterminate growth allows the plant to continue to increase in size and biomass over time.
In terms of plant structure, determinate growth often results in a compact, bushy plant with a defined shape and size, while indeterminate growth often results in a taller, more open plant with a less defined shape.
It's important to note that while many plants exhibit either determinate or indeterminate growth, there are also some plants that exhibit a combination of both types of growth. For example, tomato plants are typically classified as indeterminate but can also exhibit some determinate growth patterns depending on environmental conditions and management practices.

What are the best practices for soil preparation and management in horticulture crops, and how do they differ from those used in field crops?
Relevant answer
Answer
Soil preparation and management are essential factors that influence the growth and yield of horticultural crops. Unlike field crops, horticultural crops are typically grown on a smaller scale and in more intensive systems, such as greenhouses, high tunnels, or raised beds. Therefore, the best practices for soil preparation and management in horticultural crops can differ from those used in field crops. Here are some guidelines to follow:
  1. Soil Testing: Before planting, it's crucial to test the soil for nutrient levels, pH, and organic matter content. Soil testing helps to determine the appropriate fertilizer and amendment application rates, which can help to optimize crop growth and reduce the risk of nutrient imbalances and toxicity.
  2. Soil Amendments: Horticultural crops often require higher levels of organic matter and soil fertility than field crops. Adding organic matter in the form of compost, well-rotted manure, or cover crops can help to improve soil structure, water holding capacity, and nutrient availability. Incorporating these materials into the soil before planting can be beneficial.
  3. Soil pH: Most horticultural crops thrive in a slightly acidic soil pH range of 6.0-6.5. If the soil pH is too high or too low, plants may have difficulty accessing certain nutrients. To correct soil pH, lime or sulfur may be added to the soil according to soil test results.
  4. Irrigation: Horticultural crops generally require more frequent and precise irrigation than field crops. Proper irrigation is essential for uniform crop growth, development, and yield. Drip irrigation or other precision irrigation methods may be used to reduce water use and improve plant growth.
  5. Crop Rotation: Crop rotation is important in horticultural systems to reduce soil-borne diseases and pests. Rotating crops from different plant families can help to prevent the buildup of soil pathogens and reduce pest pressure.
  6. Mulching: Mulching can help to conserve soil moisture, regulate soil temperature, and suppress weeds in horticultural crops. Organic mulches like straw, wood chips, or leaves can be applied after planting.
In summary, horticultural crops have unique soil preparation and management requirements due to their intensive cultivation methods and higher nutrient demands. Soil testing, organic matter additions, pH management, precise irrigation, crop rotation, and mulching are some of the best practices that can help to optimize crop growth and yield.

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?
Relevant answer
Answer
This phenomenon is possible for some species but for some others it is not suitable for their growth.

I am wanting to learn more about the R/FR ratio relative to the PSS.
Relevant answer
Answer
Plants do not perceive R:FR ratio. They perceive the phytochrome photostationary state (PSS), or the ratio between the two forms of phytochrome: Pr and Pfr. Basically, each wavelength has a certain conversion effect on these two forms. For example, red light strongly converts Pr to Pfr, farred light strongly converts Pfr to Pr. Blue (yes, blue) light also converts Pr to Pfr, although not as strong as red light. So, if you grow plants in monochromatic blue light, plants would also perceive it as there's some red light around.
Sager et al. (1988, doi: 10.13031/2013.30952) made an excellent paper in which they measured the phytochrome conversion efficiency of each wavelength. Using their data and formula and the spectrum of the light you use, you can calculate the PSS of your light environment. And you should use this instead of the purely red:farred intensity ratio in your study.

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!

Is there any paper of systematic protocol?

To optimise most plant growth it is recommended that they receive 500–1000 µmols of PAR light for every m² (PPFD). Less than this and growth rates will be low :)

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?
Relevant answer
Answer
Yes it was much important to mention phytosanitary treatments in publications. Other wise there will be huge biodiversity loss to countries by invasive pests, diseases and weeds. That's why we should plan our experiments with proper care and follow all phytosanitary verifications.

Many of here offered examples are wrong. Synantropic means introduced, acclimatized and naturalized for alochtonous species, and widespread on secondary habitats for autochtonous species.

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.

The formula for the Seedling vigour index is given as:
Seedling vigour index I = Germination (%) × mean seedling length
Seedling vigour index II = Germination (%) × mean seedling dry mass
In the paper quoted below, The seedling length was taken on the 7th day.
Referred paper:
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)?

Generally, 5-10 days depending on the culture media/condition.

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.

Below mentioned suggestions might be helpful to you -
Select resistant varieties whenever possible.
  1. Avoid heavy pruning or excess applications of nitrogen fertilizer, both of which encourage new growth.
  2. Avoid planting close to wild plants of hawthorn, apple or pear.
  3. As soon as fire blight is discovered, prune off infected branches 1 foot below the diseased sections and burn them to prevent further infection. Dip pruning shears into a 10% alcohol or bleach solution between each cut to avoid transmitting the disease from one branch to another.
  4. Early applications of liquid copper are effective against this plant problem. Mix 0.5 to 2.0 oz per gallon of water and apply at silver tip and bud break — repeat at 3 to 5 day intervals up to petal fall. Use the lower rate if disease pressure is light and the higher rate when conditions favor heavy disease pressure.
  5. Bacterial spread can be reduced by applications of products that contain Streptomyces lydicus as the active ingredient. To obtain best disease control, applications should be made at the start of the bloom period and every five to seven days thereafter.
  6. SERENADE Garden is a broad spectrum, preventative bio-fungicide recommended for the control or suppression of many important plant diseases. For best results, treat prior to foliar disease development or at the first sign of infection. Repeat at 7-day intervals or as needed.
  7. The systemic action of Organocide® Plant Doctor moves throughout the entire plant to treat most common disease problems. Mix 2-1/2 to 5 tsp per gallon of water and apply to foliage. Spray to run-off, as required for disease control.

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?
