Tropical Fruit Discussion / Re: The Cherry that can take -40C
« on: March 25, 2018, 03:57:23 PM »
In a continental climate you should put a little more value on extreme periods. Check out the coldest and hottest summers and winters on record. If a arctic low decides to park itself over you in July, those cherries will be coming off the tree without having much heat at all. On the flip side of the jet stream sets up a strong vortex the heat can be unrelenting. One thing plants from up there are poor at dealing with is sustained pest pressure, as they are used to having winter come and kill off pest populations before they ever really build up. The furthest north I have seen producing standard cherries in Canada are Vernon BC and Campbell River BC.

They won't require much in the way of heat hours. We used to have a few cherry bushes in northern Alberta as a kid. I have seen them growing well in La Crete Alberta. In the Peace region of Alberta the trees leaf out mid june and first consistent snows of the year come in late september. They wouldn't have been improved cultivars but our fruits were over 1cm (1/2 inch) across with a largish seed, but fragile skin. The only other fruits I can ever remember growing up there were blueberries, raspberries, huckleberries, saskatoon berries,strawberries, apple hearty apple crab crosses. Snow or frost can occur in summer if a arctic system pushes in. We also had to carry 2 five gallon pails of lard to school uphill both ways in the driving snow, providing said driving snow hadn't drifted the doors shut.

Have a look at brazilian guava (Psidium guineense).

They fruit several times a year, but have the advantage of being much more heat and dry tolerant than jaboticaba. I prefer the fruit to jaboticaba, mine taste very much like strawberry and pineapple jam.

5 has it for 45aud a roll.

If you have extra pads, if you are still growing out the patch just put a tick down for me when you have some to spare.

I'm easy, I'll wait for a few dry days so I can wind winnow them and send them your way. I'm all planted out on dragonfruit but I'd take some prickly pear pads of good varieties next time a storm blows some off. PM me an addy or post office box.

Slow at first but this is a bigger variety and makes 2 meters in its second year, tops out at about 3 meters. They will only live 4-5 years but by then they will have self seeded.

Used the pigeon pea for cover cropping some small fruit trees, then chop and dropped them. But the chooks and king parrots liked them enough that I keep a patch going in the back corner. They self seed readily and crop very heavily. I have harvested them for dhal, but the effort is great for what I can buy at the indian food store for a few bucks. There are tons of dry pods on right now.

Whatever you go with give it some room. The neighbors planted 30m of bambusa boniopsis 5cm in from the boundary. It is a clumper but a 5 year old clump will be 1m across, so I'm contantly on spade patrol for new shoots. Give it at least 1m from the boundary. That said, it is very wind resistant and made a 4m screen in under 3 years.

If you need something quick in the meantime, pigeon peas are quick to make a 2-3 m hedge from seed, and under planted bamboo would over run them once you got it in ground. I've got heaps of them and could send a pound of seed your way should you need it.

Mike how do you rate the escarlate and red vs. the sabara and grimal? How big was the tree? Grafting has been good this year so should be more to go around.

Very professional looking, any fruit on the purple epi's or just for the flower? Also are you focus stacking?

The tree will grow better if you just use a spade and don't allow grass within 2 feet of the trunk, otherwise buy some 4 or 6 inch flexible corrugated drainage, cut a 16" section, split it lengthwise. Fit the pipe over the trunk and wire or zip tie it back together.

I've only done 2 onto mamey, but what I was told (an seemed to work) was to use scion wood that was still pliable or a bit "cheesy" with a swelling terminal bud. Use a vigorous rootstock that again hasn't really hardened off. If the bark is still grey/green and smooth/shiny that was supposed to be better than if it had become woody/fissured already. That said only 2 of 4 took.

After some time in the sun the tape will start to weaken. Long term tapes like duct tape or electric tape are made to last a long time, but tge clear medical tape is really good at sticking to tissue and degrades pretty quickly in the sun.

Tropical Fruit Discussion / Mamey- another year?

Its the middle of winter here and we're pushing zones a bit so shes looking a little yellow, but what do you think. Pull off the fruit and get another year of growth?

Green sapote grafted on seems to handle the cold

Nectarine (sunraycer) on the other end of the climate scale

Just stick them together and tape them. As long as you have vascular contact they will take. Just give it a go, it will work.

Same plant from that other post this morning

A grafted giant yellow megalanthus seedling just starting into a spring flush of growth, so should get to see how giant this type of megalanthus really is this year.

Sucked in!
Extreme -Reaching a high or the highest degree; very great.
So yes, by definition veganism is the upper extreme limit of a plant based diet, conversely carnivory is the lower extreme.

Not arguing anything. Whether you take it to the extreme of veganism or not, there is a large body of evidence showing that increases in fruit, vegetable and nut consumption correlate with decreases in all cause mortality. You are right, the study is not a cross population prospective or retrospective cohort analysis as Oscar requested, but those types of studies are given a pretty low clinical evidence level by the major clinical evidence hierarchies. There are too many uncontrolled cultural differences that can introduce bias in cross country comparisons. The first paper posted uses data from the nurses health study/ health professionals study. It is one of the best constructed prospective cohort trials ever done. The number of participants is very high, data is collected from participants for the entire time they are in the study (so it can capture changes in diet over time) and it has been running for decades. Because of the in depth followup from periodic questionnaires it can capture not only absolute risk and mortality, but also age of onset and severity of disease. Many studies use only a single starting point (say a 5 day food record) and a single end point (say cardiac death). So you are basically stuck reporting the incidence of disease, when the rate and severity are most useful especially if you are trying to figure out disability adjusted life years which are more relevant than years of life lost.

The second study is a larger more recent systematic review of prospective cohort studies. I couldn't find any systematic reviews of randomized control trials available for diet studies, so that study has the highest clinical evidence level of any I could find on pubmed/medline/embase/cochrane review. So again not a cross country analysis but it it is a very high level of evidence.

The question at the end was to highlight the fact that after 3 pages of discussion there has not been a good source of evidence presented that strongly supports some of the other diets that have been studied (atkins, keto, paleo, assorted low carb). If you want to have an interesting read on the in depth modelling of various calorie density and macronutrient ratios and thier effect on ageing,  mortality,  reproductive health and body composition check out the geometric framework mapping studies coming out of the university of sydney.

Finland and Inuit populations have low fruit/veg intake and poorer health outcomes, but there are so many other factors at play. Hazda tribesmen have been used as an example of a population that has very low plant intake but good cardiac outcomes, but in that study the oldest tribesman recorded was 72. So you would have to argue whether ir not you can compare heart disease between the hazda and western nations when they don't even live to be the age where most westerners would start to develop heart disease.

Expert opinion is relegated to the lowest level of clinical evidence, and you'd probably need to get a shovel and start digging to get low enough to find the rung of the evidence ladder that a shockumentary sits at. Knew I shouldn't have stuck my toe in to test the waters on this one.

Here you go Oscar

The question is can you find a study that fruits, nuts and vegetables significantly decreased quality or quantity of life?

They can be good mixed into a shake with other fruits that are sweet, like mango or banana. Otherwise, yes, they are very sour. Apparently there are some sweeter cultivars that can be eaten out of hand, but still sour. I like the smell but no a huge fan of the taste.

Sorry to offend Oscar, just got excited over the possible implications. I grew up in an agricultural area that does mostly canola and alfalfa. Its all automated now and there is no such thing as a small farm anymore. If this technology becomes viable and only suits mega farms, I imagine mega farms will be all that remains. If that pushes apple prices down, they'll just find more things to put apples into like they did with corn and canola.

Long post but once I started looking into it I found it fairly interesting. Apples are bigger business than I thought.

It would definitely be suited to a particular type of operation. If implemented it could do to the small orchard what modern thresher/combine units did to small grain farmers. If the same machine could be tooled to harvest several fruit crops (say mango, citrus, apples, avocado) then 1 mil would be cheap. Think of australia. Broad acre fruit farming is common here, generally on fairly flat terrain. Trellised apple orchards are more the rule than the exception. Our labor costs are high. 40%-60% of the crop is wastage because the local market can only handle so much b grade fruit, and the price for low grade fruit is too low to consider picking and shipping for processing. Last time I was in western Australia for the apple harvest there were piles of low grade fruit double overhead the size of tennis courts everywhere. If the automated picker could decrease fruit damage by getting them sorted and on trays without risking crush damage in bins, that would increase export quality volume right away. This is where the industry wants to go because the local market is saturated. I never realized how many apples the world grows but have a look at this. . I think there is volume for mass production of robots. Can that china figure be right?

Between mango, apple and citrus that's year round picking. If you run these units like the automated harvesting companies do on broad acre soy/rice/corn/grain.
1mil @ 6.5% over 10 years about 140k a year plus 5% equipment value for parts and repair and 5k insurance = 195k a year
Pick 250 days, 20 hrs a day. 105 days travel and maintenance = 50000 man hour equivalents.

That prices a machine hour at about 4 dollars. Write off interest costs in the business,  plus write offs on the depreciation schedule for plant and equipment. If you increase export quality fruit volume and cut wastage, crop volume and grade will increase. You could probably make your margin on the decreased wastage and increased export volume alone. That still leaves an 11 dollar gap assuming $15/hr for migrant labour. Early adopters would make some cash, then I imagine apple prices would crater leaving only the automated producers at a new lower floor price and normal business margins.

Long post but the ROI on equipment in my business is a fraction of that, but it still pays the bills. Automation is a threat in my line of work, so usually pretty interested in where it's at. Question is will it really be an improvement when all the unskilled jobs go overseas or to robots and the locals try the fill the gap with consumer credit and mortgage debt.

The thing about a robot is there is a large capital investment,  but low operating costs. Multiple picks wouldn't add much to cost like it would with human labor.

Do you have any in focus closeups? To my eye it looks to have a single alternate pattern with large buds, where the jaboticaba I am aware of tend to be opposing/small bud.
