Farm Kenya: Farming underground apple (Yacon)Added:
at the planting and the management of this particular plant until harvest. My name is Kelvin Yakundi. Join us as we get into this. Right. Thank you so much for joining us today. And uh Sasa, let's start and look at the basics. First of all, uh the history of uh this uh very unique crop uh your corn. How did you discover it and uh how did you where actually did it even come from? First of all, >> I'm Daniel, the founder of Wonder Innovations Limited. We are located in Kimono Gundo South Kimu County. We are mostly known for the multi-story garden where we grow, we plant vegetables in a very small space using the wonder multi-story garden. As I said, we are innovators and we also farm wonderfree. So we do not just farm. Uh so when I learned about yakon uh and I learned that it came from Peru, South America and uh it has been used for centuries.
>> But this is a very new plant in Kenya, not more than 5 years old.
>> Mhm.
>> Uh then I came across a friend of mine who was growing. uh he's the one who surprised me with the first seedings >> and I purchased 40 of them >> and they do not come cheap because one costed 500 shillings.
>> One seedling.
>> Yes.
>> Mhm.
>> Mhm.
>> So I came and planted the seedlings here in in my farm. [clears throat] >> But uh because I do not just do farming, I do it innovatory.
Mhm.
>> Uh I just used what I use and what what I'm known for. I want a multi-tory garden, >> right?
>> Uh because I learned that you have to heat the soil. You have to keep the soil in a conical shape then you plant it.
>> Mhm. uh because we have dry seasons and wet seasons uh it can work very well uh with the wet seasons but in the dry seasons when you come to irrigates or watering uh you find that all the water will be going to the sides >> right >> so that's why I came uh I came to use this concept of uh uh wonder multi-istory garden >> using one layer sometimes two layers >> so that when we irrigate using a host pipe or drip irrigation. Uh the water will just go into the plant instead of sping sideways.
>> All right. Let me take you back uh after you discovered this particular plant. And um first of all, you've said 5 years. So we're in 2026. When did you discover it? And how long has it been in your farm before we even move to the irrigation part and everything else? How long has it been in your farm?
>> I discovered it is in Kenya uh just last year.
>> Last year.
>> The month of June.
>> Mhm.
>> And I premented planting it in the month of September.
>> Last year.
>> Yes. Last year. And it takes seven months to mature.
>> Okay. Okay. So, >> all right. Before we go there, um when you are preparing your land, especially your garden, uh for it to receive the seedlings of uh the yakorn ready to receive their seedlings. What what is it that a farmer who seated at home farming shambal receive the seedlings.
If you're using the conventional way 3 ft by 3 ft round one, >> then you take your tuber or a seed.
Uh the the reason why you dip a beer a deep hole is for the leaves to to have a soft landing.
>> Mhm.
>> Uh so when you have when it comes to harvest after 7 months, it's just approing yourself [clears throat] >> the the the tuber >> and the plant safe >> then you replant again.
>> Okay.
>> So you've you've dug your hole. Um you've uh 3 ft. You said 3 ft, right? 3 ft by 3 ft.
>> By 3 ft. Right. So after you've dug your hole, you've put your tuber there. Uh so now as a farmer or a new farmer who is handling this especially to make it grow. Not not even to make it grow to help it grow. Many farmers they usually plant uh many crops. They use the right uh system or the right way of doing it. But at the middle of the growth, the plant remains stunted. But as we can see around here, the plants are really are really thriving. So during the period that you've put the tuber there uh before even the seven months, let's look at at month uh two or three what is it that a farmer needs to do?
>> Uh let me say first uh the hole I have said the hole is 3 >> 3 ft by 3 ft >> by 3 ft. dep then the spacing should be at least 4 ft uh from each hole.
>> Mhm.
>> And uh you have to use the manure. Uh uh after using the manure then you do your tubers.
>> Mhm. [clears throat] >> Uh after doing your tubers uh you should plant. It is always good to plant in the rainy season >> because uh not not all people have the advantage of uh irrigating.
Uh so in the rainy season uh especially in the month of uh March to April that's the best time to plant.
>> Mhm.
>> Uh but you can also do it using ir irrigation the way we do it here.
>> Mhm.
>> Uh [clears throat] because it's a tuber.
It just look like a sweet potato. Mhm.
[clears throat] >> In fact, it's very hard to distinguish it from a sweet potato.
>> Mhm.
>> Uh you you raise the garden if you're using the irrigation because it has to be conical the the ground. It has to be it doesn't have to be to to go that deep. It has to to be dead conical.
>> What you do, we just surround it with this pedin paper we use for the multi story garden.
>> Mhm. And then that one we ensure that the water for irrigation is not being lost in the sides.
>> Okay. All right. That's very very nicely explained. So now after irrigation um you had spoken about manure especially the whole you mix the with manure right.
So uh as as you are growing this particular plant, what kind of fertilizer advice?
Which type of fertilizer that is used?
Okay. uh farming wonder we use organic we farming so we do not use synthetic fertilizers because it doesn't take that long it's only 7 months for maturity >> we just manure once but you can also top up mostly with goat manure or cow manure but we do not recommend fertilizers commercial fertilizers >> yes >> okay so Um after now you've uh done the irrigation, you've done uh fertilizer, you're using organic fertilizer, let's go to the management of the plant over the seven months because 7 months.
Yeah. So over seven months as a farmer who is handling so that their plant uh thrives like what we are seeing here apart from watering no other man management is needed because the leaves when they are used up they just fall fall off and they also act as manure for the for the same same crop. Mhm. So, uh what is that one thing that a farmer can do wrong so that they don't grow um to the level that they've grown? Um what will make the plant stay stunted over the period that it's growing? Uh first you have to to check on the waiting. You have to wait and maybe after 3 months you can top up uh with manure.
>> Mhm. [clears throat] >> Yeah. And the spacing now you have to check on it because now if they are too close they not drive >> right. and the pest and diseases because of course as a farmer of this particular plant making sure that the plant >> the best thing with this plant.
because it doesn't need a lot of water.
Yeah. It can also be rainfed and do well.
>> Yes.
>> Okay. So what if an area well especially when you look at around Kenya now that you've been farming it soilot soil does best in Rome so it can be red, it can be white or gray.
>> Mhm. And now in this particular let's now stick to just the lom soil and look at um as a farmer after you have harvested your plant because we've spoken through we've looked at the plant how it's growing 7 months now harvest after you've harvested the soil that you've left uh from where the plant was how do you manage it for it now maybe to be uh ready for the next planting season.
>> Uh because my farm is small, uh I don't I can there's no space to shift. So what I do is just to to to dig another hole and then I mix the soil with manure and then I plant immediately.
>> Mhm. [clears throat] >> Yes. Mhm.
>> Because it's a one time crop, you you harvest one, but if you need for home consumption, uh you can just take off one or two and and consume in the house.
>> Mhm. [clears throat] Yes.
>> All right. So, let's look at also the climate now that we speaking about uh this uh this particular plant and the soil and everything. climate Kenya of course the climate there and the climate here of course difference. So how is it uh surviving especially in the in in the climate that we have in Kenya and what is it that as a farmer you are doing in order to make it um just thrive and also grow when it comes to climate climatic conditions when you look at um Kenya how how is it able to survive here?
>> I think Peru and Kenya share almost the same climate >> because we all in the tropics. So if it can do well in Peru, it can also do very well in Kenya.
>> Mhm. [clears throat] Okay. All right. Thank you for that. And also let's look at um the different seasons that we have during the year because we usually have dry seasons. We usually have a season where maybe how does that affect uh you as a farmer and while you're growing because in a visi what happens in a season when it's not raining what usually happens >> as I said uh we focus on innovation and we have a solution uh for that.
>> Mhm.
>> Uh where water is in excity or the rainfall is not adequate.
We do the dam line around it.
>> Mhm.
>> So that when you uh you water it uh the water will not just be lost.
>> It will go direct to the plant.
>> Mhm. H and in fact we had a very dry spell before before February >> and in fact that time we irrigating we have also installed drip irrigation >> around it and it helped a lot so that's why you can see it's healthy because in the dry spell we are irrigating it >> okay now because it's a tuber >> let's also look at other tubers and compare it with sweet potatoes and potatoes.
>> Come across potatoes and sweet potatoes.
Sweet potatoes and potatoes.
Is it more resilient sweet potatoes or how does it behave when it you look at sweet potatoes and potatoes? H uh the best thing with tubers is that they store their own water like a tuber like cava is a draft resistant plant because of his tuber. So even their corn just like sweet potatoes or cava uh will retain the grain because when it's dry it will feed from the tubers.
>> Okay. So you as a farmer of course you're taking care of this plant for 7 months.
in a day for after how long is give us that uh duration and also how you take care of the plant? I think I do it at random >> because there are always people here.
>> So you just make sure you go around >> sometimes the the ST may may fall off.
>> So we are supposed to leave them and maybe even tie them with a rope.
>> Mhm.
>> Yes.
>> So let's look at also the predators.
a challenge and how you deal with them.
>> Because the tubers [clears throat] Mhm.
>> Because [clears throat] the strawberries have so many there so many enemies >> but this one.
Mhm. Mhm. [clears throat] Oh yeah. So let's look at um the leaves that you of of this particular plant because >> so as a farmer the level the height when does it especially okay seven months Could it be that the plant has uh has reached maturity and you are expecting me maybe what shows you that this particular plant is now ready for harvest. What are the indicators?
>> Uh one indicator >> it produces flowers >> and [clears throat] I show you one about several which are producing flowers.
>> Mhm. [clears throat] Uh so when you see it's producing flowers that's the time you know that is uh mature and ready for harvest.
>> Mhm. [clears throat] And and do we do we usually have maybe other plants among them they grow in midway like they don't go all the way up. Do we have Strawberry is strawberry because of our innovation spirit. Uh we have even mixed corn with strawberries.
>> Ah okay. So uh with mixing with strawberries um now when you look at how that is helping your corn grow when you mix what is it that you're that you're helping the plant do when you're mixing it with uh strawberry?
>> Uh you know each plants got what it takes uh from the soil >> different nutrients. So you find uh the nutrients which is taken by a corn are not taken by the strawberry >> and we make sure that uh is when you are planting strawberry uh the strawberry planted uh where the the tubers of the yakon do not reach.
>> Mhm.
>> So we are able to utilize uh the area >> economically planting two crops >> in one area. Okay, that's good. So, let's look at also the soil health because many crops usually help the soil with the nutrients. So, for specifically, what would be the advantage after you you've you've grown your corn for this time that you've grown and then The soil has gained some sort of nutrients.
Strawberry.
Although experiment because strawberry do not like shade.
So because it's a very high value crop >> because [clears throat] 1 kilo is retaining from 500 shillings even to a,000.
>> Okay. for the market.
Now let's look at now that you've mentioned about harvest and uh this plant uh it has grown it's it's mature enough. How do you store the the the your harvest the harvest from this particular plant? How do you store it and how do you make sure that you don't get losses? Because many of the farm produce who was in Arabica after harvesting. So where do you store it and under which conditions do you store it in?
>> Yakon has many advantages because we can we cannot consider it as a perishable crop.
>> Uhhuh. Because once it's freshly picked, >> it's not as sweet as if it it stays for one. If it's there for one week, you after harvesting it becomes sweeter because by that time the sweeter it becomes.
>> All right, there you have it. Uh we were speaking or we are still speaking about um your corn type of plant. We're going to be looking at it on the second part and look at how the harvesting is done, how all this storage is done and how even it helps you there at home. Don't go too far. We'll be back with more.
All right, welcome back. This is Farm Kenya show right here on KTN and today we are speaking about a very unique plant and this plant is known as Yakon.
Remember before we went for break we were speaking about the growing and also the management of this particular plant.
It takes 7 months to grow. You can compare it with sweet potatoes and also potatoes. But this is a different type of tuber. We're going to now be looking at how you can plant it at home and what are the practices when it comes to soil when it comes to how you're going to plant this particular tuber. So join us even as we get right into this.
So now we want to see how we are going to be uh preparing our small uh particular area of the shamba that you we've chosen. So what you need to look at first of all when you're now preparing this that is a roots in a soft landing.
[clears throat] >> Now because we are innovators, >> we are farming wonder and we farm wonderfully. [clears throat] >> What we do is using our innovative HDP sheet >> for planting of corn. Mhm.
>> That one has an advantage because now if it's in the dry season watering the water will not spill out.
>> Okay. So it will retain the water.
>> Yeah. Because in the conventional way you just >> but now to contain the water that's why we are using the HDP.
>> Okay. So it's very useful when you are managing the plant especially in irrigation and when you approaching because [clears throat] now you just have to tear or unlock the boots.
>> You just unlock the boots and then it will be be very very easy to harvest your crop.
>> So this time we are using the wonder multi story >> HDP material to plant your corn.
>> All right. So let's look at what is it that we first of all what is it that you need to do?
>> Uh you identify the space >> Mhm.
>> where you want to plant.
>> Mhm.
>> Um you make you have to make sure the soil is loose. Uh then from there you can just uh plant uh the the tuber the small tuber >> and uh you have to make sure that it has some fresh young shoot.
>> Okay. So that [clears throat] when you water it or when it's raining then the shoots will just generate germinate.
>> Okay. Yes.
>> All right. So you can show us uh what uh how you usually prepare the land what you need to do especially in terms of uh looking at the quality of the soil as well and everything else. So so that at least we see uh what we are doing. So basically what he's doing here is making sure that the soil is mixed well enough uh because uh if you remember the first part of the show we were speaking about the mixture of the soil with the manure so that this is what he's doing uh and he's using the panga to do that because it's a smaller space so he can um you can just use anything I think to just mix the soil together. So after that after the mixing we will see what uh is he will be able to do.
Yeah. So uh mix up do we have any manure that we going to add here? Right.
>> We adding manure and then we mix it >> sour.
All right. And most of the time uh the the soil that you're using is of course the soil that has already even grown and uh the medium that is there is um the nutrients that are there, the roots and everything else. So he's creating another layer on top of the one on the ground in order for it now to hold whatever it is that is supposed to be held here which is the soil as well.
Yeah. Yeah. So, these are these are the bolts that he was showing us the bolts.
And uh now we are going to be adding the manure on top of it. And then I think we're going to mix, right?
>> Yes.
>> You're supposed to mix it. Can that there?
>> Yeah. So, this is the manure mixing with the soil. And then now after that um he's going to be showing us what we'll do in order for the tuber now to be held uh strongly on the ground in order for it now to start growing. So this is basically what you're supposed to be doing the whole time. So do you also plant uh the tuber on the sides or it's just in the middle?
>> Yeah, it's better if you plant just one because the canopy will develop.
>> Yeah. develop. Yeah. Okay.
>> Just one and spacing is 4 ft uh from plant to plant.
>> Okay. All right. Right. So that is the soil that had spilled uh earlier on. So uh he's putting it back on the uh the medium that you've created on on the in the middle. That that is what will be holding the tuber. Yeah. So after that we're going to be learning what is it that we need to do when it comes to uh planting of this particular tuber.
Okay. So enough we still mix it.
>> Yeah.
Press it down. It should be full.
>> Oh up to the brim, right?
>> Yeah.
>> Okay.
>> So that it will be harvesting the corn.
>> All right.
So you have to fill the the space up to the top and then when you fill it up to the top it will be easier uh during harvesting. This is what uh he's saying.
So we're going to be adding more soil on top and mixing it with the manure as well.
[snorts] >> Nah, it's okay. It's okay.
>> The goodness is we are too. So we we'll just help.
Whatever we have here, I need a watering can.
>> Uhhuh.
>> A watering can.
>> Okay. All right. So, we've filled the the area where the tuber is going to be placed up to the brim. Remember it's up to the brim. So he's going to bring the tuber and then we're going to put it and see how it's placed there. So we can look at that.
The tuber what someone needs to look at when they are planting so that at least uh we learn as well.
Uh here is the tuber uh which we plant and we got it from a parent plant which has been harvested. Mhm.
>> And you have to make sure that it has shoots >> so that when it's watered or or when it rains, >> uh the shoots will just shoot up >> to be a big plant the way you see the one background.
>> Okay.
>> So now I'm going to plant.
>> Already the the ground for planting is ready and we are using the HDP material.
uh because now we want the the the tubers to have a soft landing >> uh so they not be restricted with the hard soil. So the soil is very soft and we have already mix it with manure.
>> Mhm.
>> And the other advantage is that when you are harvesting uh you just remove the poly thing and then you harvest very very easy.
>> Okay. Uh so this is a very innovative way of planting >> your corn.
>> All right. Now let's look at how uh you plant it so that at least we see >> planting is just very simple. You make sure you dig your small hole.
>> Mhm.
>> Already the soil has manure.
>> Mhm.
>> Then you put it at a depth of 1 in.
>> Okay.
>> And then you >> cover it.
>> Yeah. Then you can cover it with a soil.
>> Mhm.
>> Just one inch.
>> Mhm.
>> Then after that you just you you you'll be watering and after one week uh this the shoot will start appearing.
>> Okay.
>> And and then after half 7 months uh you have your harvest.
>> All right. Before we even move on, now that we've covered it, uh does someone add water? Uh so that at least you know you want to make sure that your plant remains well. So does someone add water and if it's water mount uh can be added so that at least you know after one week when you come back uh do you have to water every day or you now come back and water after one week? uh if you are planting in the dry season uh you have to water it so that it can germinate but when it's raining uh there's no need of watering >> it's just like the way you plant a potato >> all right okay thank you so much for for that demonstration at least we've seen how the uh yakon tuber is uh planted we've looked at uh the preparation of the land what you need to do the space um remember you have to just dig a very not very deep in order for you to put the tuber um on inside or on top of this particular system that we've placed here. So now we're going to look at how you harvest it now that we've seen how it's planted. 7 months later when you come back and maybe you have um a plant that is grown, how do you harvest it so that at least at the end of the day you understand especially what is it that you do? And this is the mature one. This this one has stayed here for 7 months.
So we're going to be looking at what process is done or what it goes through for us to harvest this. So when especially what you look at so that at least you release it from this uh particular space.
>> Okay.
HDP material >> heat resistant. It have a lifespan of over 10 years. Wow.
>> And this is just our innovations because we are innovators.
So we wanted to make it easier harvesting their right now.
Mhm.
Right. So that is basically releasing the the soil.
Yeah. And as we can see also there are roots that have formed.
Yes.
So >> yes yes you see now you start seeing the tubers.
>> Yeah the tubers are there.
>> So this is the corn.
So when as you continue let's also speak about the market uh the the market that you have because I remember before we went for break earlier on on the first part you spoke about the price that uh one tuber goes for so you can tell us a little bit about that as even as we continue to entangle this from the from the uh space. Uh um in fact I've been marketing uh before harvest >> uh like on Saturday 4th >> uh we participated in the hab festival.
>> Mhm.
>> Uh in Mituki Park, Nairobi.
>> Okay.
>> And uh we talked to many customers.
>> Mhm.
>> And we showcased how we do Yakon. And in fact we had so many contacts.
>> Mhm. uh or those who are going to supply uh once we harvest >> and now harvesting has started. So I know there are so many people with diabetes, health challenges >> and it will be of much help because this one does not contain the harmful sugar.
>> Okay, >> it's sugary but the h the sugar is not has no nutritional value and it has other ingredients. Okay.
>> Which chop? We chop the body.
>> Yes.
>> In here.
Poly.
>> Yes. So this is the corn. And uh as we are looking at this in in a kakama sweet potato and also it looks like a potato.
So this is what we were speaking about.
We've been able to uh this is the way of harvesting. uh as you as you remember we've been just uh removing removing the soil around it and also uh making sure that everything goes well. So this is basically the whole plant and the roots are the parts that are harvested. So when it's removed h this is what will go to the shamba right and how you'll remove it from now this Mhm.
Mhm.
All right.
So, so just let a bucket.
>> Give us a clean bucket. So we are removing and he is removing the soil from the yakon so that at least we put it uh on this bucket and then after this we're going to be weighing them because remember he told us he takes them to the market so that at least uh they can uh be uh sold and also get to the customers who need them. Right? So uh at that time because they are underground. We don't usually see that.
>> It's very rare.
>> So harvest how many kilos?
>> Uh from 4 kilos to 5 kilos.
>> Okay.
>> Right now We will know exactly.
[laughter] >> So when you look at them, you might think it's a sweet potato, but clearly you can see there's some sort of a bit a little bit of difference in a way. Yeah.
But this is how of course usually tubers look like and uh we are about to get done with the ones that we have. Um we have harvested uh this is a sample of what we have harvested and before that remember we weighed it and it was of course 8 kgs but what you saw on your screen was 7.7 that was minus this one. Yes. So this is what uh we this is what has come out.
remember the journey that we've come the whole journey how the land is prepared the manure and everything else and what is involved in everything that we are doing so this is what we've come up with and before we go I would like uh you to tell us um just give us an encouragement young people out there who are trying to get into this type of farming what they can do so that at least we complete this >> I would like to advise young people that you have to be passionate about something. Uh it doesn't matter whether you are trained in a certain field but you are interested is what counts >> and solving a problem.
>> Mhm. uh for example me I'm an old man and when I came this I I found the the way they are planting them has to be improved and that's why I improvise the HDP polyin >> so that uh the tubers we have a soft landing and harvesting will also be too easy and let me say that I I I my background ground is not farming in fact it's engineering I did electrical engineering uh back those days and uh but my passion has always been farming even when I was a small boy >> Mhm. until I finished uh all levels.
That's when I started seriously doing uh farming and also I'm an innovator. I'm the one who came up with this idea of uh planting vegetables on Wonder Multitory Gardens. All right, we've come to the end of this edition of Farm Kenya and I'm holding on to one piece of yakon.
Remember, we harvested many uh earlier on and I'm going now to break it. at least we taste and see what this is all about. And I'm going to pass it on uh to of course our farmer here today and we're going to taste it together so that at least we see what this is all about.
>> The tasting ceremony is here.
>> Mhm.
>> This is really nice.
>> It's yummy.
>> Mhm. It's very yummy.
>> And this is something that at least you can plant at home as well. It tastes like carrot in a way. It tastes like carrot and it's very very sweet as well.
So this is something that at least you can also plant at home and you've heard his advice a youth out there. This is something you can plant at home and become a farmer even as we move on. My name is Kelvin Yakundi. This is what I'll be eating as I finish the show. See you next time.
