if the durian tree is sufficiently fertilised then they are able to bear alot of fruits.

bro, what do you mean by having 7-8 combs ? 7-8 combs per tree ??

Para:

I think he meant that for each bunch, leave only 7-8 good combs to remain and develop. Banana bunches normally have up to 12 or more combs, but those combs that develop after the 8th comb or so tend become smaller, which means they get lower prices (Grade C or worse). Most normal berangan should be cared for like that, with exception of some newer varieties which can bear up to 12 combs of minimum grade B. But I don't think those are commercially available in Malaysia. Maybe can check with MINT (Malaysia Institute of Nuclear Technology). I remember they had some partnership program with UPM and private companies like UP, KLK, AAR etc.

Hi Michael J,

It is always good to know what is short for the tree then I can apply the fertilizer accordinly. I don't intend to reduce the ferterlizer at this moment until it is bring me the right productivity.

Hi Mr Farmer,

As I know, there is no way to prevent minimizing the flower drops from downfall. If any forumer know the tactics, please share.

I never have a chance to taste the real "Red Prawn" from Penang. Is your friend's farm in Penang? Really wanna try the Red Prawn and Black Thorn from Penang. If the tree only carry 25-30 fruits, then the fruit should be big. It is also depends the tree's age. Most of the planters I know in Johor and Pahang will keep as maximum number of durian fruit as possible if the tree can carry. Only very few planters will cut the fruit off the tree in order to make sure the fruit grow bigger.

Hi Para,

Any tactis to share?

Would sure like to lay my hands on these !

Added on March 15, 2012, 6:26 pmFriend farm is in Sabah, about 100 Km from mine. Was told that they initially ship the Red Prawn from Peninsular, bit by bit via courier (long story). Anyway, his farm is along the trunk road linking Sabah with Brunei & Sarawak. He get very good price selling his produce himself (retail) along the road side. The taste is beyond words.

That remind what my father used to do. My father used to have the clones from Thailand last time (30 years ago). it was not an easy task those day.

The taste is beyond words..... walau errr..... this makes me need to prepare my trip to Penang to have it on April. I just read the news in The Star, Penang durian session start at mid April.

just now got a call from the N.Sembilan Dept of Agriculture telling me i was selected for the course titled

Amalan Pertanian Bersepadu(IPM)

excited to attend it next tuesday & wednesday

wow..congratz, must be great contributor in agri

Congratulation.
Please share course material / experience after attending. Am sure we can benefit too.

Just came back from the clinic again, on 2nd day MC. Doc says too much stress. Stay away from your farm he says.

Taking a short break next week.

After my visit to a few farms in Raub & Kemayan, to minimize flower drops is by doing foliar spraying which my sifu is consulting the farms to do.

it can be done as attested by those Musang King Farmers there

Hi Guys, found this interesting Fertigation for Oil Palm while doing some search on irrigation / fertigation. Just to share with you.

http://www.autopot.com.au/content/document...%20-%20pfda.pdf

I am thinking of a low cost (running/set up) irrigation (that can be upgraded to fertigation) for use in my farm (no electricity).
My project, I'm thinking of building a rig to raise up a water tank (say 8 ~ 10 feet from ground level), to create a gravity drop to run the fertigation / irrigation line. But then again, I still need energy / power to raise the water to the tank.

Alternatively, I can use a small solar panel to run a small (fish tank) pump to pressurize the fertigation line. I saw this set up at Sin Seng Huat running about 500 macro drippers by just using a small fish tank pump). The solar panel could be costly and the might be a risk of being stolen from the farm.

Any suggestion? Would like to do a trial on small scale.

MrFarmer:

Ahahaha.... yea... the Autopot system. I think Para got in touch with Jim some time back.

Actually, MrFarmer, you don't need electricity to raise the water up to the tank. You could build and use a hand-powered Archimedes Screw. http://en.wikipedia.org/wiki/Archimedes'_screw

Once you are able to draw water into the tanks consistently, then you can just use simple gravity and Venturi pipes to deliver water to your crops. http://en.wikipedia.org/wiki/Venturi_effect


Still involved with Bioeconomy thing.... But it is getting very interesting. Can't divulge much, but let's just say that agriculture biotechnology is getting a lot of attention.

Well the Autopot system is quite expensive to implement and doesnt make much economic sense for small players like us.

the Archimedes Screw is a very interesting read....

Para:

The Archimedes Screw is also not something difficult to build. And it can be built in a way that it is attached to either a 2T or 4T motorcycle engine, or a waterwhee powered by a flowing riverl.

But most people would prefer using a pump instead, since it is usually faster and less bulky.

Thanks for the suggestions guys.
I had did some research on the screw pumps before. The screw pump is good for large displacement of water, the problem is the it does not provide good "pump head" (raising the water to a height, creating pressure). Hence good for irrigating flat / undulating land.

I already have a pump in my farm, small 5 hp petrol driven pump. I find it quite expensive to run it for a long period. Had also experimented with sprinkle system, but these need to run on a long period and need labor intervention. Short of hands at the moment. When we were planting greens vegetables, we run the pump 1 1/2 hours in the morning and 1 1/2 hours in the evening daily (except when it rained). Had stopped planting green vegetables at the moment.

Am moving on to fruit trees. Hence am thinking about dripping system and how to make it low cost, mobile, less labor intensive. Am testing this system to help in transplanting of saplings. The first 2 weeks after transplanting is critical for many plants. My first experiment is on 6 papaya saplings. 3 was just transplant without any aid. 3 was transplanted with a shade of banana leaves. The banana leaves dried off after 3 days and were affecting the saplings. I took 3 soft drink bottles, punch a very small hole at the bottom and created a very simple drip system. I fill up the bottle every alternative day for a week. Now the papaya plant is growing on its own.

The 3 sapling without aids, dried off after the fifth day.

Am going back to my farm tomorrow and armed with about 200 seeds of Mas Solo papaya. Has to have this is place before transplanting. My search on the net, we can actually hang a drip bag ( a big version that they use in the hospital) to create a drip. Have a rough sketch in my mind, maybe use those 5 kg cooking oil bottle or whatever big bottle to create a drip. from my earlier experiment and search on the net, am quite sure this shall work. Now my problem is that to fill up say 150 bottles on alternative days is quite labor intensive.

And to create a permanent dripping system, is quite expensive (interior), no experience and am not ready (me). Alternatively I could assign a hand to water these saplings daily by running the pump.

If I could successfully develop this, I can use it during the first 2 weeks of transplanting and adapt it to feed liquid fertilizer. What do you guys think?

Mr Farmer:

You are right to say there's a limit to how high a traditional Archimedes screw can lift water. But with a little more imagination, you can still use Archimedes screws to lift water to very high levels (8-10 feet) into a central storage tank and create the necessary pressure for gravity feeding. Or am I the only one considering a tiered system of Archimedes screws for lifting water....? Mmm.... As I know it, a modern variant of the Archimedes screw, aka screw conveyors are commonly used in grain processing factories to lift grains like wheat and corn kernels up to silos about 10-15 feet high at least.

If you have a flowing river nearby, even better, can use the kinetic energy of the flowing river to power the whole thing, using an undershot water wheel. No need bicycle or motorcycle engine.

http://en.wikipedia.org/wiki/Water_wheel
http://en.wikipedia.org/wiki/Poncelet_wheel

In addition, the use of a Venturi pipe would help maintain stable pressure on the outflowing water from the water tank.

Actually, come to think of it, if you have a river with strong enough current, you could just build a water turbine. Not sure if you guys remember primary school science project involving construction of a dynamo, but the principle is pretty much the same. Generate your own electricity.

http://www.enotes.com/topic/Water_turbine

Just think of water turbines as an inverted wind turbine powered by water flow instead of wind.


Your idea is good, and in fact quite widely used also. As you've pointed out quite correctly, it is a chore to refill all those bottles every alternate day. I have a crazy idea, which involves the use of rain collection troughs, lots of stilts, and lots of floatation plugs. If you know how fuel gauges work in cars, then you might get what I'm thinking about. The main shortfall of this is that the troughs are only of certain lengths and strengths, so each plot has to be of a certain size only, and multiple water tanks are needed.

My partner and I are looking into venturing into the aquaculture industry. We have identified an 8 acre land that is currently farming red tilapia. We are planning to acquire the farm and take over the existing business. There are currently 8 ponds. 6 big pond which the owner says can rear anything from 20000 - 40000 tilapia and another 2 ponds that we can use to rear fingerlings.

I need to know how profitable this business is and whether its a good venture to get into. Both me and my partner will be managing the farm full time. The running cost of the farm currently is about RM 60k/ mth and 90% of that cost comes from feed (about 1000 bags/ mth). We are hoping to harvest at least 15 tons of fish each month.

My questions are:
1. Is tilapia prices stable? We have an agreement from the feed supplier that if we take the feed from them, they will buy our fish but I'm not too sure if the price is stable.
2. What are the risk when venturing into this business?
3. Is demand for tilapia now more than supply?

I would greatly appreciate any feedbacks from forummers here. Would also be interested to visit existing Tilapia farms out there.

Thanks in advance

Elmer:

Based on current trends, tilapia prices are stable, but gradually reducing, especially for frozen whole fish. Live fish gets better prices, but are niche markets. The best market are with processed fillets.

There are many risks involved with any kind of aquaculture business. Maybe you should have identified them ahead first. It is good that the feed supplier has guaranteed buyback. Some of the most common risks include:

(i) Disease outbreak - particular concern in high density earthen pond cultures
(ii) Policy risks - Eg. tilapia from China got barred from entering Europe due to antibiotic residues; same concern in Vietnam and Thailand
(iii) Market risk - Although prices are relatively stable, and demand is still comparatively high, there is a real risk of the market being flooded in the near future (<5 years). In such a case, producers with the lowest cost and highest quality will thrive

Demand now is still higher than supply, due to tilapia being a cheap fish compared to other white fish. The same can't be said in the next 5 years. Just look at what happened with salmon prices; it nearly halved after large scale aquaculture took place. But as wild fisheries begin to dwindle, this species will play a more significant role in the market place. A case in point: I went to inspect some markets to gauge the production and demand of cultured fish species a couple weeks back. Cultured siakap, pompano and catfish were piled prominently on the tables, but couldn't find red tilapia. When asked the wholesalers, they said "all sold out".

But why shouldn't it be completely sold out? With prices of marine fishes hitting the high double digits per kg, it is no surprise. I mean, even cultured siakap was being sold at about RM20 per kg wholesale. Catfish sells cheap (African catfish and pangasius sells for low single digits per kg), but their taste and texture really can't replace those of white fish like snapper, pomfret, or bream. Also, cultured catfish tend to be fatty, so less flesh is available per kg compared to lean fish like tilapia.

But really, Elmer, what kind of returns do you hope to get? 20% or more?

Hi Elmer,
Looking at your questions, I am wondering if you have any hands-on experience in running a fish farm (or such a big scale). Not trying to "pour cold water", but do consider an exit plan just in case things don't goes according to your plan. It's very easy to "buy into" a venture, but very difficult to exit, especially if it is not doing well.

Am sure you would have work out your budgeting and funding for your project, since you mentioned 60K/ mth = 720K/year. Your rolling capital, mean time to harvest, etc.

Also it might be interesting to verify the reasons for the sale of the farm.
Standard reasons are most probably getting old, retiring, sickness, no children wants to take over, migrating...blah, blah....

Personally, I do not have any experience in agriculture/aquaculture.
Was in Ipoh a few months back, there is this guy that deliver Red Tilapia to Ipoh. Story is that their boss got a permit to rear these fishes at a dam in upper Perak and under their "agreement" certain % is for export and certain % needs to to sold off locally. He is doing the local sales, frozen Tilapia both wholesale & retail.
Good luck. Would sure like to visit your new farm.

Added on March 28, 2012, 9:54 pmThanks for your suggestion MJ, unfortunately there is only a small creek at my farm, where I had widen it to a pool at a certain section. There is practically no water current and water level is below the land about 10 to 15 feet (depending on the season).
Wind turbine/ Solar panel is not an option as it's quite costly, need continuous wind current, theft & etc.

I think I may be able to grasp your idea. But then rain collection troughs interfere/compete with sunlight. Hope to have this system working especially during drought season. And mobility.

So far, I am thinking of using a standard 25 liter tank (from discarded herbicide) attach a 4 mm tube to a micro drip. As I had not find out about the flow rate /pressure of the micro drips, rough guess a 25 liter could last for 4 ~ 6 days before refilling. Could use a wheelbarrow or a truck to drive to the pool, refill , then distribute the tanks. Or run the pump, use hose to fill up all tanks. What do you think?

MrFarmer:

Whoa! That is really low water level. I thought I recalled that flooding used to be an issue. Maybe I've confused you with someone else.

As I said, your idea is good, just laborious. Why not just test it and see? Never try, never know, and it will always just remain an idea on paper. But please do clean the herbicide barrels thoroughly, including soaking with soapy water for a few days. Herbicide residue can still be dangerous for crops.

Hi guys... i was randomly reading about hydroponics, then aeroponics, then it brought me to fertigation, that led me to Cili Fertigasi and then it led me here after a stop by the autopot site...lolz...

was planning on starting small with a mini fertigation "farm" behind my house to just try it out before things get serious. any opinion on this business you can share?
