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.

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.

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

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!

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.

IMG_20180715_114922.jpgIMG_20180715_114640~2.jpgIMG_20180715_114708~2.jpgIMG_20180715_114804~2.jpgIMG_20180715_114828~2.jpgIMG_20180715_101508~3.jpg

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.

First inflorescence of Enza Zaden cherry tomatoes in aquaponics sand culture yield trials.. here is an image FYI.

IMG_20180719_092717~2.jpg

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.

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

IMG_20180724_190412~2.jpg
- night blooming ridgegourd and snakegourd flowers in the hanging garden

IMG_20180724_213611~2.jpgIMG_20180723_215050~2.jpg
- 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.

VKN, I hope that you and your family are safe.  Have you been impacted by the flooding?

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.

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.

We at NARDC are the first prize winners in the BEST Start-up Company category at RISC 2018 organized by NIRDPR, Hyderabad!

RISC 2018 2.jpg

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..

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.

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

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.

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.
