  1. 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
  2. As evening fruit snacks.. For some it is a weed..my operator at NARDC was about to remove them from our aquaponics sand culture yield trial unit. How many of us can name this plant, say its uses (leaves and fruits) and are aware of its medicinal benefits? “Let food be thy medicine and medicine be thy food”. - Hippocrates -
  3. Post pictures, Aufin. Not seen one from you for months.
  4. I am closed to debate on this subject, Ande. Sorry, nothing more to add for now please. Have a nice weekend!
  5. Not only in this article, none of the listed ones has a reference to Mark's works. Doesn't it look something strange? Or could be ongoing academic turf war? Somehow I felt the need to point it out..just seems a bit myopic to me. Setting up a study like that or should be better.. coming soon from a couple of universities and private initiatives in India who also believed in what we have been doing. If you do have a question, “But what about when….," I have no clue, Ande. I can only wish and hope people, the new aquaponics adapters, get what is right and it is sustainable. Cheers!
  6. Ande, not really. Clearly they are not aware that sand culture in aquaponics exists. It has been a vital growing system ever since hydroponics came into existence. "The only paper we are aware of is by Lennard and Leonard [15] compares floating rafts, gravel beds, and NFT for growing lettuce in AP and found that NFT produced significantly less biomass and removed the nutrients from fish water less efficiently than the other two systems." Reference #15: Lennard, W.A.; Leonard, B.V. A comparison of three different hydroponic sub-systems (gravel bed, floating and nutrient film technique) in an Aquaponic test system. Aquac. Int. 2006, 14, 539–550. [Google Scholar] [CrossRef] References are also made to the works of Rakocy, Adler, Savidov, etc., but they missed this. "McMurtry, M.R., et al. 1990. Sand culture of vegetables using recirculating aquacultural effluents. Applied Agricultural Research. Vol. 5, No. 4. (Fall). p.280.284." Over to you.
  7. Good collection, Ande..but to me it all appears to be half-cooked stories. What am I missing? For example, #5, how could academia make statements like those without comparing the yield results of aquaponics sand culture systems aka iAVs. I couldnt observe mention of Mark anywhere as well. What do you think?
  8. Kids scribble art using aquaponics veggies.. here is another one. Which one did you like? Original or its black & white copy?
  9. And, for today's lunch..
  10. Sunny day..here is a picture of the mini okra forest that we have.. Arka Anamika, the YVMV resistant cultivar of okra (ladies finger) commercial yield trial in aquaponics sand culture at NARDC Nanniode. Seeds are from IIHR, Bangalore. Progress has been good. Harvesting in batches every other day. Plants pumping out baby okras at a good rate. Expecting 25-30 kg per m2 or maybe more this season. It is evident that sand culture is producing greater yields than conventional soil culture for okra. Observed some early stage infestation of leaf rollers, leafhoppers, fruit borers, and mealybugs and we are working on several/most all IPM ways to reduce the potential yield loss due to these pests. Prevention (with a capital P) is always better than cure. Mark used to say this all the time. I am curious to know what are your organic pest management practices and wonder how you take care of your okra crop? Any okra lovers/growers?
  11. Aufin, labels sure..have a dozen or some more to be added in this list. The single white lacey flower is snake gourd and the cluster is that of bottlegourd.
  12. "Little flower, but if I could understand what you are, root and all in all, I should know what God and man is." - Tennyson - These two dozen+ flower pictures are from our backyard aquaponica, Nanniode. Early morning scout and pouring rain today, could not get more clear pictures. If you could not correctly guess any of the plant names, let me know. Biodiversity is the key to sustainable food production especially when you are attempting to grow your own food. No toxic pesticides or chemical fertilizer supplements allowed, whatsoever..
  13. 1. A day for environmental reparations! Wish you another World Environment Day.. 2. This is also the day we at NARDC had begun aquaponics journey of organic farming in 2012 and has continued its work on a daily basis to this day. 3. Pictured is second phase works that began today at CSAF #3 Alappuzha.. Mr. Sree Nagesh, the franchise proprietor, laying the first brick at his demonstration aquaponics facility near Niranam, Kerala.
  14. For today's lunch.. Thank you A2 for another scribble art using aquaponics brinjals..
  15. Most plant species thrive in aquaponics sand culture systems.. Here are update pictures from our new yield trials at Nanniode. A small patch of 12-week-old hybrid red lady papaya and sugarcane (as per kids request) are in the last stages of development.
