  1. 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
  2. The youth are the future of a food-secure world. Yet around the world, few young people see a future for themselves in agriculture or rural areas. Urban and rural youth face many hurdles in trying to earn a sustainable livelihood. Attracting and retaining youth in agriculture has been a key challenge for several decades. I can now confidently assert that aquaponics sand culture (iAVs) is a concrete solution to these issues by both rural and urban adoptions. I was with these young people now taking care of the TNJFU Aquaponics Research Complex, Madavaram, Chennai. They are into doing several things under the excellent direct leadership of the VC of TNJFU and the guidance of the Dean and Professors of Dr. MGR Fisheries College & Research Institute, Ponneri; adding the second batch of fish next week, new plants coming up nicely, battling some pest issues, and most importantly gathering so much data from their direct field experience. Data + Aquaponics - what a novel concept! Hope Mark would say WOW again..
  3. We are nearing the climax of papaya yield trials in aquaponics sand culture.. here is a picture for you.
  4. With Koi Carps 2000 fingerlings, ISKCON Aquaponics and CSAF Madurai had gone live the day before yesterday. This is the first time we are trialing Koi Carps in aquaponics sand culture considering/selecting this fish primarily from a horticulture perspective based on ISKCON beliefs. To know more about what ISKCON does, their beliefs, world-wide presence, etc. here is a link. http://www.iskcon.org/ However, we have got a buy-back offer in staggered harvest from its supplier for distribution to aquarium/ornamental retail fish industry. This is only a prototype. If all goes well, we would soon be witnessing one of the largest commercial installations in several acres scale (between 100 and 1000 acres) in Madurai, Tamilnadu. Wish us luck!
  5. Thank you Aufin. Way to go!
  6. Sugarcane as teatime snacks.. Grown in aquaponics sand culture for kids, they are more sugary and tasty!
  7. For the pacu lovers.. Here is an image of the red-bellied pacu (nutter) seedlings that were added today at SVVU Aquaponics, Fisheries Research Station, Sree Venkateswara Veterinary University, Undi, Andhrapradesh, India.
  8. We were playing with sand again at ISKCON Aquaponics today! This is a prototype open-field partial rain-shelter protected structure build in about 200 m2 for hopefully a much larger commercial aquaponics enterprise in multiple acreage scale by NARDC's CSAF Madurai - Avyukta Aquaponics. Fish planned - Koi Carp Plants in yield trials - Coriander (Cilantro), Mint, Cucumbers, Tomatoes, Chillies, Brinjal, Snakegourd, Bittergourd, Ash gourd, Pumpkin, Paneer Rose, Marikolundhu (artemisia pallens), etc. Techniques in yield comparison trials - sand culture flood/drain, sand culture constant flow, sand bucket culture, cucumber mats, vining crops in A-frame; semi-decoupled raft culture, nutrient flow culture in A-frame and vertical frame, etc. A go-live event by ISKCON is planned on October 19, 2018. More later. Questions welcome!
  9. Another aquaponics peeragogy meeting with the fisheries scientists, professors Suguna and Veerabadra Rao, at SVVU-FRS, Undi, AP.. Commercial scale planting of tomatoes, cucumbers, spinach, okra, and a local variety of chakkarakeli bananas are in their first crop that began today. More later.
  10. New product we are now distributing..Heirloom Clove Beans Seeds. Scientific name: Ipomoea Muricata Common names: Nitya Vazhuthana (നിത്യവഴുതന), Kattuthali (Tamil), Mitchi (Hindi and Bengali), Garyo (Gujarati), Gariya (Marathi), etc. These heirloom clove beans facing almost extinction are being raised in our aquaponics sand culture nursery facility that are naturally decontaminated and controlled for diseases. This gives you a good healthy plant to start with. This is very important. It is a very easy-to-grow vining plant and can be grown throughout the year. The tender and swollen pedicel of the fruit is used as a delicious vegetable. The edible fruits are prepared into tasty curries just as brinjal, okra, or coccinia (little gourd). Leaves are used in natural pest control. It is replicated using seeds. FYI..
  11. Good leadership is about capacity building. That's what TNJFU is focusing on. A good leader is not someone who gives you the fish - he is the one who teaches you how to fish. Current agriculture technologies fail to consider the underlying problems which are destroying agriculture. NARDC has the knowledge to implement and replicate Aquaponics organic farming movement combining the RAS (recirculating aquaculture systems) and organic olericulture on scale. That's what we are happily working with TNJFU. As we complete phase 1 works today at TNJFU-ICAR-KVK Aquaponics demonstration facility at Sikkal, Nagapattinam, here is a picture for you. More later.
  12. Working with CSAF Madurai in producing tonnes of mint leaves per day.. It has given a new dimension to us growing in commercial aquaponics sand culture in acreage scale, hopefully in several acres of mint/coriander production. What do you think are the challenges ahead? Any large scale mint growers? Pictured is high quality fresh-cut mint for today's breakfast at Nanniode. 10 days mint yield data in aquaponics sand culture.. 152 grams per square feet at 8-9 inches. Expecting 300+ grams per square feet at about 12-16 inches long in 20 days. Is this good or bad? Currently looking out to compare this data with other organic growing techniques including soil culture. Can anyone point me to a study?
  13. "The fruit of your own hard work is the sweetest." - Deepika Padukone - The fruits from this papaya tree is almost there.. This is from our aquaponics sand culture yield and optimization trials at NARDC. No need for any fancy plumbing or filtration gimmicks. Your satisfaction will come only from the doing and not in the telling.
  14. 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"
  15. 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.
  16. 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..
  17. 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.
  18. 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. "A teacher affects eternity; he can never tell where his influence stops." - Henry Adams -
  19. 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.
  20. 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..
  21. 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.
  22. 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.
  23. 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.
  24. 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?
  25. 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.
