Latest / Hydroponics Daily / Growing Edamame Indoors: Japan's Hydroponic Breakthrough
Transcript
- 0:00Hello, hello, hello. Welcome back to Hydroponics Daily, your go-to podcast for
- 0:05everything soilless cultivation.
- 0:06I'm your host, Dr. Russell Shaw. I am the founder of Utrema Limited,
- 0:11and we make novel fertilizers,
- 0:14interesting biostimulants, and organic biopesticides that can be used in conventional
- 0:19or hydroponic or organic cultivation.
- 0:24Today, I thought I'd do an episode about the cultivation
- 0:27of a japanese delicacy adami or
- 0:31adamami perhaps i eat
- 0:34this and i have no idea how you pronounce it i pronounce in
- 0:37our house we pronounce it adami but maybe
- 0:40that's incorrect anyway it is a staple in japanese and asian culture far east
- 0:47and i eat it when i go to wagamamas if you ever go to wagamamas in the uk then
- 0:52they they serve you this and it's delicious It's a legume,
- 0:58so it produces a pod that contains beans that you then pop out.
- 1:04You don't eat the coating, it's not like monge-tu.
- 1:08So you eat them and the problem is that they are harvested in the summer in
- 1:14Japan and the quality deteriorates rapidly in storage.
- 1:19So a number of Japanese scientists have looked at cultivating it hydroponically
- 1:23under LED lights indoors, where they can control the light, the temperature,
- 1:27the humidity, carbon dioxide, and nutrient delivery. And.
- 1:31They've been able to produce stable yields independent
- 1:35of the climatic conditions and it was conducted at
- 1:38Jose University and the University of Tokyo and
- 1:42this the these big guys have been working on LED lighting for
- 1:45a number of years in tomatoes and so they thought they'd
- 1:48look at this as well so it was Professor Toshio
- 1:51Sano and from the Faculty of
- 1:54Biosciences and Applied Chemistry so it's
- 1:58so i said it's usually harvested in the summer but the freshness deteriorates
- 2:02and long-term storage is difficult so to
- 2:05overcome those barriers they're looking at hydroponics particularly nft using
- 2:08rockwool and then mist culture they they talk about so i'm not sure what mist
- 2:13culture involves if you know is it aeroponics but it can't be if it's nft and
- 2:18rockwool so something's lost in translation there they found more vigorous plant
- 2:23growth producing stronger stems,
- 2:25healthier leaves and greater biomass than other hydroponic methods and traditional
- 2:29open field cultivation.
- 2:31So the method could be used to produce in conventional farms.
- 2:35What else can we say about this study on these crops?
- 2:39The hydroponic method produced a higher sugar content which is good because this is a sweet.
- 2:47Delicacy even though it's a vegetable can be
- 2:50used in desserts as well i think the free amino
- 2:53acid levels were lower so perhaps less health
- 2:56benefits but the isoflavones which give the compounds the health benefits as
- 3:02well and the tastes were significantly higher so this suggests that led lighting
- 3:07may stimulate the synthesis of those bioactive compounds so altogether better
- 3:14taste healthier promotion.
- 3:16The research is important because adami is a nutrient-dense,
- 3:21high-protein crop, whereas most hydroponic crops are not high-protein,
- 3:28and certainly leafy greens are not nutrient-dense.
- 3:31So it breaks the long-standing assumption that legumes can't be cultivated in
- 3:37artificial light-type plant factories.
- 3:39So it's a world-first success demonstrating and growing delicious adami anywhere, anytime. And...
- 3:47Be interesting to know if they used a nitrogen-based fertilizer because
- 3:50you can grow just because legumes don't
- 3:54need nitrogen because of the nitrogen-fixing bacteria in
- 3:57their root nodules doesn't mean that you
- 4:00can't supply nitrogen so it's just that
- 4:03you don't get that you're basically paying for nitrogen when you don't have to
- 4:06so it'd be interesting to see if anyone is looking
- 4:08to grow a legume and we're looking are looking for a nitrogen-free feed then
- 4:13we can make one up here utreema for you that's not a problem we can we'd be
- 4:17we'd love to research production of any type of legume in hydroponics with you
- 4:24and we can lend our plant nutrition expertise,
- 4:28to and it could be something that you could build ip around
- 4:31because there are not many legume crops it doesn't
- 4:34have to be adami although that is a good high value crop could be chickpeas
- 4:40could be anything you want to be a short crop that's the other thing is the
- 4:45beauty of Adami is that it's not a big long trellis forming type of plant like say monge 2 would be or.
- 4:54Runner beans or broad beans I don't know what you call those in America farba
- 4:59beans, cannelloni kidney beans,
- 5:02you want a short plant, especially for an indoor vertical farm where you can
- 5:06get multiple layers shorter plants, more in line with say lettuce than tomato and,
- 5:13this one works with that. So yeah, if you are interested in looking at optimizing
- 5:18the nutrition for a different crop, then I think legumes is a great one to try, because things like.
- 5:24Mangetu, adami, they're a bit more higher value than lettuce,
- 5:29which, you know, as we've talked about in the past,
- 5:32struggles to make money for many vertical farms.
- 5:34So maybe my friend Chris down in Dartmoor would be interested in this one for
- 5:39his new hydroponic farm. If so, get in touch.
- 5:43The other reason why legumes are not grown often in hydroponics is because you
- 5:48have to have the plants long enough for them to flower and be pollinated by bees.
- 5:56Legumes are pollinated by bees, bumblebees, so you need a pollinator in there
- 5:59or some sort of hand pollination, some sort of vibrating tools to pollinate them.
- 6:04And you then have to wait for the seeds to set and fill with the protein.
- 6:10And being an annual, they will then die off and you'll have to start again.
- 6:14So I guess you would struggle to buy this.
- 6:19Well, no, you should be able to buy adami seeds in the UK and in America.
- 6:23It's not just in Japan. And even if you struggle, I'm sure you can get someone to import them.
- 6:28Anyway, that's been a really interesting story, even if it's not been a long one.
- 6:32If you've had success growing legumes in hydroponics, then please let me know.
- 6:37I am i think i've grown some obviously there's
- 6:41microgreens and things like pea shoots and stuff like that but
- 6:44you don't even need any fertilizer and hardly any light to grow those so they
- 6:48are not difficult at all so i suppose they are the one hydroponic crop but when
- 6:53you get beyond that and you actually have to harvest what is essentially the
- 6:56fruit and the seeds then it becomes a lot more difficult and i'm not aware of
- 7:01anyone doing that commercially,
- 7:03let me know if I'm wrong. Okay, that's been Hydroponics Daily for today.
- 7:07If you found this useful, please do leave us an Apple podcast review if you're
- 7:12listening on an Apple device. If you're not listening on an Apple device,
- 7:16then just make sure you follow the podcast and please check out utreema.co.uk.
- 7:22As I say, we're experts in plant nutrition and if we don't have something that
- 7:27you need, we could either make it or tell you where to buy it from,
- 7:30the best source and we won't even make any money from that or just help you
- 7:33out at the goodness of our heart
- 7:34because you listen to our podcast thank you very much for listening to today
- 7:38and i've no idea what i'm going to talk about tomorrow but i'm sure it'd be
- 7:41an absolute banger goodbye.
