Posted July 9 (edited) 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. Edited July 9 by vkn (see edit history) Share this post Link to post Share on other sites
Posted July 11 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. Share this post Link to post Share on other sites
Posted July 11 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 ande likes this Share this post Link to post Share on other sites
Posted July 15 (edited) 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!

Posted July 17 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?

Posted July 20 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?

Posted July 25 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. Share this post Link to post Share on other sites

Posted September 4 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. ande and bigdaddy like this Share this post Link to post Share on other sites
Posted September 4 (edited) 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. Edited September 4 by vkn (see edit history) Share this post Link to post Share on other sites
Posted September 4 (edited) 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..

Posted September 10 VKN, Glad you have avoided the majority of the flooding. Regarding your papaya tree cultivation, are you growing those in your typical rectangular sand bed that is about 12" deep or are you using a different setup...? Sure appreciate all the good photos and insight you provide. Stay dry..........mh Share this post Link to post Share on other sites

Sure appreciate all the good photos and insight you provide. Stay dry..........mh 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.
