  1. Another way in reaching out Mark with direct financial aid is, "Use my paypal act at paypal.me/MMcMurtry123 same as https://www.paypal.com/paypalme/my/profile?locale.x=en_US&country.x=US"
  2. Dear all, I have created this topic to document our own IAVS progress and findings.. In brief, we have over 2+ years of hands-on experience working with various commercial-scale Aquaponics systems.. media beds, NFTs, DWCs, etc. We are now building our first batch of sand beds believing in the IAVS vision. This is to apply as an extension to our current systems. Next, I will update you the progress with some pictures. I look forward to your support. Please share your questions, comments, suggestions.. Thank you.. Kind regards, vkn
  3. Sent an email to Mark already and hopefully he is able to read and respond to his email. I am so happy he got evacuated in time unharmed from such a tragedy, disaster and loss. No words for this huge shock and no one can go back and change what has happened. Our thoughts and prayers are with the good doctor for a new start.
  4. Fresh after-school snacks for kids today.. It's the first fruit of Red Lady papaya in aquaponics sand culture yield trial at Nanniode. Hope they make better cuts for you next time..
  5. Hi MH, they are supposedly dwarf papaya species growing in the old/matured 12-16 inches deep sand culture beds. I was initially worried about the roots effecting the liners. I had to cut down many when they began hitting the roof of the rain shelter structure. Noted they have medium tap roots and have developed many side feeders, the largest concentration being at the top 10 inches. There is no risk with shorter beds but if I do the same thing over again, I would keep slightly deeper filter beds and more spacing for trees such as papaya, banana, or black pepper plants.
  6. Happy Teachers Day! On this teacher's day, here is thanks to all my teachers and mentors at APN especially the Jedi master Mark who may also be reading this. "Luke: Master, moving stones around is one thing. This is totally different. Yoda: No. No different. Only different in your mind. You must unlearn what you have learned. Luke: All right, I'll give it a try. Yoda: No. Try not. Do… or do not. There is no try." Source: Star Wars Episode V: The Empire Strikes Back When Luke tells Yoda that he'll try his darnedest, Yoda scolds him. ... Basically, to Yoda, "trying" doesn't accomplish much. Luke should either decide that he can lift the X-wing fighter out and do it, or make up his mind to quit. Learning to use the Force is a mental game, so your state of mind is what matters most.

  7. Papaya yield trial in aquaponics sand culture.. This is the first yield trial at NARDC to access the commercial suitability of red lady hybrid papaya cultivar in aquaponics sand culture conditions. They are being evaluated for growth, yield, quality and pest incidences. The progress has been satisfactory up to now. Here is a picture for you.
  8. We at NARDC are the first prize winners in the BEST Start-up Company category at RISC 2018 organized by NIRDPR, Hyderabad! Oh, did you know we have become a private limited company since December 2017 after having been working on aquaponics ways of organic farming for over 6 years with a focused purpose of "global replication of right aquaponics organic farming movement for water conservation and food security!" NARDC is currently working in partnership with several universities, NGOs, the private sector organizations, individual farmers and certified sustainable aquaponics franchisees (CSAF) developing scalable aquaponics organic farming solutions that have a real impact on poverty reduction, food security and ecosystem health. This national recognition means a new beginning for us. Lots more can be accomplished working together with RTP, NIRDPR and Ministry of Rural Development team at national level. Over to you..
  9. FYI.. The projects that are currently being replicated are as follows.. 1. CSAF Madurai, a prototype project in 180 m2 build area, built to test the concepts for a much larger commercial replication hopefully in between 100 and 1000 acreage area. We will have both solution and substrate culture models such as nutrient flow culture, raft culture, and sand culture here. 2. CSAF Bangalore Zone 3, 1000 m2 CEA-GH, first of its kind and largest installation we made this far. 3. TNJFU's second demonstration project in collaboration with ICAR-KVK at Nagapattinam, Tamilnadu, 200 m2.
  10. Thank you for expressing your concerns. Several things happening around us and I have almost got sidetracked with them. So is this delayed reply. Fortunately our location, Nanniode, is in high grounds and we did not have any adverse effect at all. One of our aquaponics replications was submerged under water completely for a week or so.. It being a raised fish culture tank, fish are safe. Plants were lost almost 90% except some tall peppers. Cleaning of mud/renovation work is currently going on. Hopefully it goes well.
  11. After dark pest scouting in the backyard aquaponica could also yield some interesting scenes such as these.. - roof touching papaya tree inside a rain-shelter structure, several trees in the trial were cut down due to this - night blooming ridgegourd and snakegourd flowers in the hanging garden - tomato army worm, this could make a leafless plant in a couple of days. Prevention (with a capital P) is better than cure.. an alert to use 'Panchasoothram' from hereon.
  12. First inflorescence of Enza Zaden cherry tomatoes in aquaponics sand culture yield trials.. here is an image FYI. Second most consumable vegetable after potato in the world, first in terms of total nutrients to human diet among vegetables, consumed in fresh form and various processed forms like soup, sauce, ketchup, puree, paste, canned, etc., tomato tops the list of processed vegetables. In aquaponics sand culture, semi-indeterminate Arka Rakshak tomato yields have been proved several times at >150 kg per m2 per year (@4 plants x 2.6 crops x 15 kg). Commercial aquaponics if done right is not a diabolical fantasy. We are very enthusiastic about this trial at NARDC. Today’s consumers want vegetables that are both tasty and healthy (pesticide-free). Priced at average Rs. 150/- per kg (INR), highest being Rs. 300/-, add 30% organic premium rate, there is absolute market potential for cherry tomatoes in India. Your comments?
  13. I experienced almost similar results in some of the old trials.. roots, growth and yield were much better but then most of the systems with looser sand clogged after say 18 months or so.
  14. Here is some data and a picture album dedicated to Today's Fresh Aquaponics, NARDCs CSAF, a commercial aquaponics sand culture demonstration facility at Kollam, Kerala. Plants in focus: Arka Rakshak tomatoes, Arka Anamika okra, Enza Zaden cucumbers, heirloom snakegourd, bittergourd, bottlegourd, lablab beans, stevia, brijal, etc. Biodiversity and polyculture organic farming is key focus in this demo facility. Mean daily temperature: 29/25 degree celcius Precipitation: 20% Humidity: 86% Wind speed: 11 mph NW Flower buds induction and growth/development of new leaves is adequate. Natural pollination seems normal, however, hand pollination is to be practiced well by the operators. Suggested use of an electric toothbrush as well. Plant stretch and stem elongation rate seems appropriate. Plant diseases hardly observed except a few cases of tomato virus. On rain shelter protected structure: A rain shelter is a greenhouse-like unit, in which only the roof is covered with a transparent or translucent material that is impervious to rain. It can either have no or open sidewalls but has no mechanical ventilation or heating system. Rain shelters are increasingly being viewed as more sustainable than totally enclosed greenhouses because they require a much lower initial capital investment. Temperatures in these structures are generally lower than in totally enclosed greenhouses, and if appropriately managed, yields and productivity are arguably higher than in greenhouses or open field production. Particularly in heavy rain areas, its effectiveness is quite high. Challenges ahead: Cucumber beetle Fruit flies Bittergourd caterpillars Mealybugs Sanitation related issues More work to be done in tomato trellis and cluster support. Whatelse?
  15. Noble Aquaponics (NARDCs CSAF Alappuzha) had gone live on Friday. A 100 m2 demonstration farm facility, it is an owner operated subsistence farming model, surplus produce sold to the local community. Noble team will lead the aquaponics replication efforts from now on in Alappuzha district of Kerala. It was kindly inaugurated by the Niranam Gramapanchayat President and Agricultural Officer with blessings from all the near and dear ones of Sreenagesh's family. Happy aquaponicing, Noble team!
  16. Arka Anamika okra cultivar is another crop we found it suitable for cultivation in domestic as well as in large scale commercial aquaponics sand culture units. For the aquaponics data enthusiasts, here is some from our Arka Anamika yield trial.. Note, it is a work in progress. Questions welcome. Number of plants per square meter - 9 Minimum days to flowering - 31.97 Days to fruit setting - 36.87 Maximum plant height - 120.38 cm (still growing) Pods per plant - 20.40 (and counting) Pod weight per plant - 560.6 gm Yield per square meter - 5.045 kg
  17. It was time to train the Enza Zaden cherry tomato plants by attaching the vine twines and vine clips. Here is an update picture of the yield trial at Nanniode.
  18. This info has warned us the need for better precautions and to be sure to follow them wherever possible. Appreciate your thoughts, Big Daddy. FYI.. we have very minimal exposure areas to its dust. I have no idea how they handle it at the mining or crushing/sieving/mixing process though. We get them packed tight in 50 kg bags (value-added). I have to work on appropriate precautions when they are 1) unloaded dry from trucks, 2) carried headloaded dry to the filter beds, 3) times of wet surface levelling, etc. I'm also hoping it for a long time that the quarries wash the dust away before dispatching it. Not so lucky this far. If you could get washed sand, go for it even though it comes at a premium price.
  19. Chanced upon to this info on Quartz Si sand while searching for something on Zeolites.. All good info for the practitioners, so sharing. Comments welcome. http://www.inchem.org/documents/icsc/icsc/eics0808.htm First, PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! SPILLAGE DISPOSAL/personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Danger: May cause cancer if inhaled. Causes damage to the lungs, the immune system and the kidneys through prolonged or repeated exposure if inhaled. Do NOT take working clothes home.
  20. Hi Ande, I am aware of this myth and possibly another misconception regarding bottlegourd juice. A member of the cucurbitaceae family, it is a very common vegetable in India and is a hot sell commercially. I have begun drinking its juice raw couple of months ago ever since I was diagnosed as mild diabetic and borderline hypertensive. We grow this amazing vegetable all the time and family uses it cooked.. Experts try to reveal the truth here. Please give it a reading. https://food.ndtv.com/health/is-drinking-lauki-juice-harmful-de-bunking-the-myth-1841589 Also this https://food.ndtv.com/food-drinks/7-incredible-benefits-of-drinking-of-bottle-gourd-lauki-juice-1452828. Cheers!
  21. Loki as fresh juice and as a vegetable for today's lunch from the hanging aquaponics gardens at Nanniode.. Some weighing over 2.2 kg, 8-12 fruits per plant at a spacing of 2-3 plants per square meter, consider bottlegourd as another successful vine crop in both domestic and commercial aquaponics sand culture applications. Have you also heard bottlegourds are magic vegetables as a medicine? Any thoughts?
  22. Chanced upon to this NFDB's Matsya Bharat Newsletter.. Several distorted information about our work and NARDC's display pictures.. Request all future journalists and writers to talk with us first and get current relevant and right info and latest pictures on the subjects related to us and other stuff that matters. 1. Great to read a good intro of Dr. Mark R. McMurtry at page 5 para 1 and pàge 11 para 13.2. 2. Happy to see NARDC team 2014 along with MPEDA doing Seabass Aquaponics Nursery demonstration event and news picture of The Hindu newspaper at page 8 para 7. 3. Exciting to see several NARDC pictures at Aquaponics in India development article page 11 para 13.2. Plese note most all given numbers are incorrect. Talk to us again. 4. Good to see one of the NARDC consulted projects in 2014 is featured - Anjali Aquaponics, Telangana; page 11 para 13.3 5. Surprised to see one of the NARDC trainee cum overnight commercial aquaponics consultant is also featured at page 12 para 13.4. 6. Good to see Gary and his microponics is also featured at page 14 para 15. https://www.google.co.in/url?sa=t&source=web&rct=j&url=http://nfdb.gov.in/PDF/NEWSLETTERS/15_Matsya%2520Bharat%2520January-March%25202017.pdf&ved=2ahUKEwjqx46M6vbbAhXFs48KHeqyBlwQFjAAegQIAhAB&usg=AOvVaw0Lm6eqo_6lp0HEi75A4x2C Over to you..
  23. Precisely 3 months and 3 days.. here is a short update from Today's Fresh Aquaponics, our CSAF #1 for Kollam district, Kerala. Total commercial demo build area 800 m2. 1. Fish Nile Tilapia 7000 or so grown from 1 gram to averaging 150 grams, the highest being 220 grams on surface feeding catch. There are bigger ones ready to begin harvests. 2. Plants assorted. Completed spinach and amaranth harvests as secondary crops in a pristine filter, now focussing on Arka Rakshak tomatoes, Arka Anamika okra, hybrid cucumbers including Enza Zaden, and small patches of lablab beans, snake gourds, bitter gourd, stevia, and brinjal plants. 3. Addressing several challenges related to absconding/new operators and IPM. Way to go! More later.
  24. Not Elderberry..maybe similar species. This is black nightshade (Solanum nigrum.) We cook and eat leaves like spinach and use unripe fruits in various dishes. Ripe ones are eaten as is. Considered as a medicinal plant as well.
  25. Enza Zaden cherry tomatoes in aquaponics sand culture.. We started commercial yield trial recently. Has anyone tried this costly seeds at about Rs. 8/- (INR) per seed? Any info on yields and price per kg appreciated. Hopefully end result is like the second picture. Courtesy: Enza Zaden
