Experimental Gardening: Quinoa

Quinoa is one of the things we like to call Ooh Aah Foods – wonder foods that some of our hippy neighbours consider a cure-all for everything. Originating from the South Americas it really is a wonderful grain, and very healthful; stuffed with essential amino acids, and high in Calcium, Phosphorus and Iron. We really like eating it. Trouble is, its damn expensive.
Back in late Autumn, while I was still largely unable to tackle any serious gardening, I looked at a packet of Quinoa, and, true to form, though to myself, “How hard can it be? I mean, millions of peasant farmers in South America have been growing this stuff for centuries... why shouldn't I Give It A Go?”

So I did. A little research told me that there are many, many strains of Quinoa (Chenopodium quinoa, so quite closely related to the Chickweed that so prolifically sprouts all over our Winter veggie garden) adapted mainly for various altitudes ranging from coastal plains in Chile to the high Andes of Bolivia and Peru. It is a cool-weather species, so definitely something for our usually-sparse Winter garden. On the other hand, we don't get frosts, so we're ahead of the game in that regard.

The packet of Quinoa we had in the grocery cupboard was on we bought off the “health food” shelf of our local supermarket, and originated from Peru, so it looked to me like the odds were stacked against us. I guess that Quinoa from Peru is more likely to be a high-altitude variety, and we are at a decidedly low altitude. Then, too, many imported foodstuffs get irradiated – supposedly to ensure that no produce-borne diseases make it into the country. On the other hand, irradiated foods are usually labelled as such (though not always, since such labelling is not a hard legal requirement) and I would assume that the very reputable health-food packager would be somewhat sensitive to the issues of food irradiation. So my guess was that the Quinoa was not really very likely to have been irradiated, which would naturally kill the germ-plasm, and make germination impossible. There was also some question as to the suitability of our quite heavy soil for Quinoa cultivation.

Nothing daunted, I cleared a small patch in one of the veggie beds, about ½ a metre long, and sowed a handful of the Quinoa “grain” by simply scattering it on the prepared soil surface and raking the grains shallowly into the soil.

Much to my delight, it germinated within about a week or ten days (as my frequently failing memory serves.) It grew away quite happily, though numbers dwindled steadily through the Winter as every bug in the land decided to have a munch on this new, exotic foodstuff. Losses were compounded by my “neglectful” methods of growing things – I tend not to water crops except at critical times. Mainly we lack an adequate source of irrigation water and are forced to rely on rainfall. I suppose you could argue that it is a simple case of bowing to the inevitable, but I call it a “selection pressure” in evolving varieties that grow well under the conditions we have available.

Quinoa Grain HeadsNow it is Springtime, and the 5 or so remaining plants have produced lovely little heads of grain. The plants are a bit spindly and grew to about knee-high before forming flower-heads. As they show clear signs of drying and are beginning to lose of of the grains I pulled the plants out of the ground to finish drying them indoors. The next stage of the experiment will be figuring out how to process the grain further: Quinoa grains are coated in a soapy (saponin) layer that needs to be washed off before the grain is edible. I consider this saponin layer a huge advantage under our growing conditions, as we “suffer” from losing a lot of small seed-crops to birds. The Cabbage tribe are particularly favourite targets for myriad seed-eating birds, as are the (Summer growing) seed Amaranths; the birds have an uncanny knack of stripping out seed pods and heads just a few days before they're truly ripe enough to harvest. I've come to the conclusion that the only solution will be to completely cage such crops if we're determined to grow them. The Quinoa, on the other hand, suffers no such depredations due to its unpalatable soapy coating, so that's a big win!

All in all, I will definitely grow Quinoa again next Winter, and on a much more adventurous scale. This could even be a viable cash crop for us, given the very high prices it commands. I will do things a little differently, though: I believe we will obtain much better yields if we start the plants in seed-trays and transplant them to a more regular spacing in a much better prepared bed. Bug protection will probably be best achieved by interplanting the Quinoa with other trap crops (Buckwheat, perhaps.)

It's been an interesting little experiment, and one that rates as a good success with exciting prospects for our food future, so I am happy to count on it being a regular in our Winter garden.

New Kid on the Block

An unexpected phone-call from Deborah next door a few mornings ago. "Do you want a Rooster?" A bit of discussion needed, there...

On the one hand our flock really does need a Rooster to look after them after the Tragedy On Honey-Badger Hill that resulted in the loss of our trusty knights. On the other, we've really been enjoying the peaceful mornings undisturbed by the crowing!

GMO Scam Followup

Quickly: A short article on how Monsanto's biotech maize which is supposed to be resistant to corn root worm attack, is "losing its effectiveness".

The article is pretty vague on just why this "effectiveness" is being lost, and Monsanto are naturally trying to spin this is "small numbers, minor incidence, easily managed". But I think it's pretty obvious what is going on here, don't you?

Tamarillos

Tamarillo (a.k.a. Tree Tomato or Solanum betaceum) always do well for us. They're largely disease-free, and pests don't seem to like them much, either. Well, except for a Baboon, once...

The only problem they suffer from is wind. The branches are very brittle, and have a tendency to break in strong winds. Or when occupied by a Baboon. Or when heavily laden with ripe fruit, as they are right now. On the other hand they seem pretty much immune to the predations of birds and stinging insects thanks to their tough skins.

For some time I have been contemplating growing up a bunch of them to plant as avenue crops further downslope from the veggie garden. This would give us a low-energy-input harvest, and put more of our (sorely under-utilised) land to better use. Low maintenance harvests seem more and more important to me the older I get!

I would like to alternate the Tamarillo rows with Granadillas (which also grow spectacularly well in our soil and climate) and perhaps grain avenues between the rows in Winter. Or possibly interplant the Tamarillos and Granadillas in the same rows! After all, the Tamarillos are much taller, whilst the Grandillas would shade out weeds and grass from the base, and the wire supports needed for Granadillas might help to stabilise the Tamarillos against wind.

The only trouble with this fantasy is that Tree Tomatoes are a relatively unknown crop in SA, and I'm dubious about the idea of producing something that requires me to first educate the market. History shows that the first-mover in such markets almost never makes a success story; that usually belongs to the second comer who enters the already-educated market...

Tamarillos are really easy to propogate. Just sow seed saved from really, really ripe fruit into seed-trays, pricking out into pots or tubes when they reach a size where they're easily handled. I've even had plants self-seed and grow successfully. Transplant into their permanent homes can be as soon as they 15 or 20cm tall. They're not what I would call Long Lived plants, so (like Granadillas/Passion Fruit) I would probably embark on a 3- to 5-year rotation scheme, planting only 1/3 to 1/5 of the total cropping area each year.

We have two different strains of Tamarillo, one being shorter, but I don't see any real advantage to the shorter strain. They don't seem to have been any better at handling wind or fruit loads. I'll probably have to consider planting a wind-break to try and protect them a little.

We use them to make Chutneys and Jams, which are turning out to be really popular barter items at the local weekly swap-meet, since the two of us really cannot consume the fruits of even a single tree. I also munch a whole lot of the fresh fruits while working in the garden, but it hardly makes much of a dent in the crop.

Perhaps I need to buy a Tractor to help with all the work I have in mind... certainly there's much more than I could possibly tackle by hand. I'd probably only hang onto one for a year or two while I carry out all the transformations I'd love to make before selling it on, so I don't view it as a huge money-sink. Hmmmm...

Help Wanted: Mystery Eggplant

Call them Aubergine. Call them Brinjal. Call them Eggfruit. Call them anything you like, but I love Eggplant. Especially when they're from my own garden! Organically grown, they just taste hugely better than shop-bought.

This year I have 3 varieties growing. Or maybe more... (and that's where I need your help!)

I planted Black Beauty (common locally), Japanese White (which I've grown before and loved) and (new to me) Korean Long Black. The Korean Black has been a start performer. By far the earliest, and really trouble-free. We had the first pickings for supper the other night, and the flavour is beyond my abilities to describe. I don't believe I've ever tasted another Eggplant that can compare!

Trouble is, there's a Fly In The Soup. A couple of the "Korean Black" plants are clearly not. Korean Black, that is. Even quite early in their growth it was apparent that they were not true to type, lacking the darkness of stem and leaf that the rest of their bed-fellows show.

So here presented, for your delectation and my edification, some rogue Eggplants. The seed all came from the same packet as the Korean Black, so I guess there was a mixup by whoever packed the seed for Baker Creek Seeds (the supplier I bought them off). Not a problem for me - I'm equally happy to have some new varieties, even if I don't know just what they are. They may or may not be the same variety, these two rogues. Your guess as good as mine.

There is, of course, a chance that they may have cross-pollinated with the surrounding Korean Blacks, but hey... life's full of random! So I'll be saving their seed separately towards the end of the season (all gods willing!)

Can't wait to taste them!

But if any of you, Dear Readers, are able to put a name to them, please, please drop me a line and let them know.

It's a funny thing... many gardeners are pretty casual about the names of varieties and will casually call a variety something new. Me, I like to honour the gardener who first bred the variety by trying - as best I can - to keep the name given it by that gardener, though they may be a thousand years passed-on!

The Great GMO Scam

I am assuming that we all understand roughly the same thing when I speak in abbreviated fashion about Genetically Modified Organisms -- particularly GMO food plants. Some people are tempted to sidetrack the conversation into irrelevancies with arguments like, "All our food crops are genetically modified, anyway, because we've been selectively breeding them for thousands of years." While true, it is either foolish misdirection, or deliberate obfuscation of the crucial differences between conventional genetic evolution (whether consciously directed by ourselves, or whether the result of natural evolutionary pressures) and the deliberate introduction, removal or rearrangement of isolated snippets of genetic material into otherwise-unrelated gene sequences using advanced cellular "surgery". Those who deliberately obfuscate this point clearly have an agenda.

I am no techno-luddite. I am not opposed to improving the yields, flavours, nutrition or agronomic properties of the 5 Fs1 that constitute our reasons for farming. Quite the opposite.

Hell, we've been doing this stuff for thousands of years, as witness the amazing variety of delicious and nutritious heirloom varieties we still have access to3. I am actively engaged in various small projects to try and cultivate new veg varieties using traditional methods. So its not progress per se that worries me, but I am deeply bothered by the whole pro-GMO lobby and its bought politicians.

In short, I think that the whole GMO programme is (at best) stupid. (At worst it is an out and out con job conceived and executed by greedy, lying bandits.)

Parts of the GMO Proposition might even be dangerous, as some GMO opponents argue. Certainly the effects of introducing essentially alien genetic material into our life-support systems largely untested seems a bit foolish and short-sighted, at best. But frankly I am spectacularly uninterested in whether we humans do actually endanger ourselves by introducing weird genetic combinations into our food-supply. We will reap as we sow.

I am equally pretty unworried by the possibility that a Tomato might harbour Cow genes to the detriment of my (vegetarian) karma. I do understand those arguments. They may have substantial merit. But they interest me not. They are Other Peoples' Problems.

I am concerned by the PR schmaltz spread by the pro-GM lobby. At best it is yet another manifestation of nothing more nor less than the usual corporate self-serving, soul-sucking greed, greed and more greed. At worst it fuels a smokescreen that blinds people to the true dangers of this technology, that suffocates the honest debate, thoughtful challenges and many very serious questions we should be asking about GMO crops under a blanket of misdirection, deceit, ad hominem denunciation, pseudo-answers and frequently, outright lies.

The Central Problem Of GMO is this: Evolution.

Life on this planet evolves4. As the energy flows impacting any ecosystem change – be they changes in rainfall, solar-energy infall, atmospheric CO2 concentrations, trace elements or key nutrients,... just anything, in fact – so the ecosystem changes, adapts to the new reality. And that means that the organisms within ecosystems are in a constant and ongoing state of flux, genes ever dancing and gyring to adapt to changes. Life has been doing this for something like 3.5 billion years – basically ever since the Earth got cool enough for any life forms to exist.

We're really very, very good at evolving. All of us Earthicans! We're all evolution Badasses of the highest capability.

To put it another way, the Central Problem Of GMO is this: It Cannot Possibly Work.

Let's take a quick look at some of the things we're told that "genetically-modified" crops are going to really great for:

  • Pest- and disease-resistance. This has really been the main song sung by the pro-GM lobby so far. We're told that by growing these "genetically enhanced" crops we won't have to use as much toxic pesticide, fungicide, herbicide as we5 currently do, "So really, choosing GMO crops are a very Green thing to do!"
  • Resistance to agrichemicals design to kill off pests, competitors or diseases that prey on our crops.
  • We can add Antibiotics/Vitamins/Trace elements to our food supply, thereby enhancing peoples' health and wellbeing at a very tiny cost. Good! I have no objection to that, as long as people have a clear and informed choice in the matter. That means Food Labelling. However, I think there's likely to be some unexpected fallout...
  • And the latest in a desperate gambit to keep those GMO profits rolling in... GMO crops can be engineered6 to be drought resistant, so that we don't have to worry so much about rapid global climate change.

The first two are pretty closely related. In both cases the germplasm of a crop-plant is modified to impart a resistance to environmental pressures. In both cases the outcome is very highly predictable... evolution happens.

In the first case the pests and diseases that the genetically-modified variety is supposed to resist evolve their way past the newly-injected defences, bringing the whole affair back to its starting point: a crop plant that no longer has resistances to those pests and diseases.

In the second case it is extremely likely that the pests/diseases that we're spraying against will out-evolve the agrichemicals involved. Just as before, we're soon back to square one.

The last two arguments might have some merit, except that we are perfectly able to introduce the necessary nutrients and breed drought-resistance into our crops by a combination of conventional breeding practice and sound soil-management. (Read: Organic cultivation.) At no cost at all. I am working on drought -resistant Tomatoes and Potatoes right now.

I don't wish to delve too deeply into the issues around the transfer of modified genetic material into the wild. It happens. That is well documented. And unscrupulous, greedy corporate blood-suckers want (and, so far, too frequently succeed) at gouging money from unsuspecting farmers who have been the unwilling recipients of this alien germplasm. Suffice to point out that Roundup-Ready weeds are well documented as wild plants. So the Genetically Modified genes have escaped into the wild, with no telling what the consequences might be. Stupid, stupid, stupid!

Now I don't believe that microbiologists are stupid people. Quite the contrary. It is my experience that they are highly intelligent, thoughtful people. So I greatly doubt that they are unaware of this Fact Of Evolution. I'm pretty sure they know that the rest of the ecosystem is going to evolve around the manipulated organisms introduced into it. There is no other possibility. In part I believe that scientists don't really have a very good idea, yet, of just how quickly evolution happens. We are just beginning to find out. It seems that resistances show up in as short a time as 3 or 4 growing seasons! Much faster than anyone expected.

Interestingly, the pro-GMO lobby somehow altogether fails to mention that their products are certain to be out-evolved in short order. In other words, the useful lifespan of such a product – the timespan for which it is likely to be effective for the purpose claimed by its makers – is really quite short. After which we'll need to do something else to "combat" the "hostile" predators, pests and diseases that seek to enjoy their portion of our crops. I'm pretty sure I know what the agri-industrialists are likely to propose... More and newer GMO crops, allowing us to use new and stronger chemical cocktails in the "War on Bugs".

And so another Arms Race chases its own tail...

In short, I don't believe that the GMO industry is telling the full story. And why would they, since the full story doesn't paint a picture that leads inexorably to Perpetual Profit. I would guess that the Techies (the scientists involved) are simply not allowed a voice by their corporate overlords, since the truth is so much more complex and nuanced than the Marketing Department would like. So much more ambiguous and uncertain.

In even shorter, the GMO producers are misleading everybody. They're lying.

They're prepared to risk unpredictable (possibly lethal) consequences on the ecosystems we depend upon for life, all in the name of This Quarter's Profits.
