Citrus General Discussion / Re: Deficiency
« on: Today at 04:22:06 AM »
Manganese deficiency seems likely but Zn and Mg deficiencies can look similar. Zn and manganese are often applied together but often its a sign something else is going on.

Dwarf macadamias have been around a while and I am still waiting for the seedless macadamia.

Nitrates can reduce calcium uptake and many of the N fertlisers acidify the soil. Without a pic of the plant or soil it is hard to know anything much. Something is either missing or in excess in the soil or pH is wrong.


Calling Houston the eagle has landed and just making sure it is in fact the same vegie as on the handsome paw.

The D x Z come in 2 basic forms. One small unridged orange one that is ok and a larger ridged reddish more zib like one. The latter is the one to get. Yes the king of fruit alright. Those with uncultured palates and newbies don't get it. I guess to a lesser extent people new to avos sometimes don't get why people like them so much.

It is the only plant I identified to avoid in this thread. They are a serious pest with seeds viable in the soil for over 20 years. While the seeds are kinda edible for people they can only be used in small volumes for fodder and yes hair falls out. My neighbour has a 40 ft one that chucks seeds around everywhere. They just get called Lucaena here and it appears that they are also allelopathic so there are lots of reasons to avoid this species.

Isn' black gold Texas tea and a jackfruit. Solid suggestions there and you better pick your plants well after all this effort that will take place. Believe only a small proportion of what you read and only half of what you see. Always ask if the fruit is sour and what is the flesh yield when dealing with unknowns. You do need bulk input so work on that. Nutrients are secondary atm and many more mobile ones will leave the scene before before the soil develops. Just get humus, the A horizon and soil life going.

Manhattan is an island.North and South America together is one big island. Containment has a lot to do with governments acting swiftly and decisively, the population responding properly and having a decent public health system. If the actions fly in the face of personal freedoms then some places are more exposed culturally. The quality of leadership in some places where covid has run riot is questionable also. There are a few places that better have people planting vegies right now because they are in for a long haul but not everywhere.


Found an article on the prelude to the interaction I spoke of.

They look pretty good and I'm guessing they are around a pound each and have 2 seeds/fruit? I think it was Whitman/Grimal who received seeds from Don Gray of the Gray variety which is very good. Whitman/Grimal grew them and found them to be excellent. Gray variety looks much like this and have been in Florida for more than 40 years. I wonder if these could have derived from that same lineage.

This type of disappointment happens quite a bit and people often aren't straight with whether a fruit is good to eat out of hand. Very few comment that they are pleasantly surprised at how good their Theobroma fruit really are. Many Eugenia and several Jabs are like this.

In the breeding for new reds such as the pictured MRS 649-1 at Marroochy, PP atemoya was crossed with a red sugar apple/atemoya hybrid rather than red reticulatas on the grounds of taste. The breeding of new Annonas is quite advanced at this research station and have a look at the attached report. No cherilatas were bred at all as there was a strong commercial focus. Still they won't release all the new types.

Cross that with this and we could be getting some eye popping fruit.

If immunity is gained by getting it and then recovering it will still be a small proportion of the pop of all countries. It is hard to know why containment is so much harder in some places than others.

There are a few hay grasses that you can keep chopping down that would work. Big tree legumes that you chop down would work but avoid weedy types like luecaena.

This is not easy but I'll stab in the dark. That one first could be anything even prainiana, the second might be something like brasiliensis or a relative and the third looks bit like luc's but achachairu can look similar.
I might also stick a few some time and see if anyone gets any right because its tough with this genus even with new growth.

They authors of that paper I mentioned did most of their research in the Harvard library so yes it is hard to believe. They also declared no conflicts of interest which is rather odd. What is good is that people can put ideas up into the public domain and everyone can comment and share ideas. Yes it should be respectful. All good ideas and philosophies can be defended by their advocates and people can choose to believe what they like. Not all places and eras have been like that.

Grass is important if you are taking a succession approach. If it we me and funds were plentiful I would get soil delivered with a reasonable clay content (but not pan forming types), spread and then get truckloads of organic matter of all types especially council free mulch if it is available. Stables.chicken farms whatever should be pressed for support. It will break down faster than you think.

Yeah there are a few versions of suluk in southern Borneo according to my chums. My red prawn did alright last season and fruit were just as good as penang88 but they are not as productive of course. Some of these crosses I mentioned from Borneo I will need to post some pix of so people can see. The ridged cross between zib and dulcis is said to be great as is the kut x zib. Nothing wrong with seedlng and really most will be similar to the parent and take just a little longer and even overtake grafted one in productivity in the long term.
I reckon you will see a surprising difference in growth rates between the varieties. I have 5 good sized fruiting durians and 2 are flowering now. I have one more spot and its either big fruiting dulcis, kut x zib or dulcis x zib.

In this neck of the woods it is the avian interlopers which cause the most damage. I am sure you don't have cockatoo and rainbow lorikeet equivalents to pester you. Here at least hey don't suffer insect pests much and diseases rarely impact them.

Turning sand into soil will be a long process. Mobile nutrients, liquid applications,water and smaller particles go through the profile too easily being lost to plants. I think the best first step is to build an A horizon full of humus. While bringing in topsoils would be great you will need a continual supply of mulch that breaks down and in high volume. It takes a lot of organic material to make a relatively thin layer of soil.

I use the terms interchangeably. Yes hey airlayer/marcott well and can be done when dormant even and chopped off when they flush. No rejection issues and they throw roots out pretty fast. Seedlings fruit fast so this is a good option also.

No rootstock at all. Seedlngs and marcots. They fruit fast.

The most conprehensive scientific assessment of moon gardening done to date is:

The review came to the following conclusions in 2020 :

5. Conclusions
Science has widely established different evidences: (i) the Moon’s gravity on the Earth cannot have
any e ect on the life cycle of plants due to the fact that it is  almost 300,000 times lower
that the Earth’s gravity; (ii) since all the oceans are communicated and we can consider their size being
the size of the Earth, the Moon’s influence on the tides is 10􀀀6 ms􀀀2, but for a 2 m height plant such
value is 3  10􀀀13 ms􀀀2 and, therefore, completely imperceptible; (iii) the Moon’s illuminance cannot
have any effect on plant life since it is, at best, 128,000 times lower than the minimum of sunlight on an
average day; (iv) the rest of possible effects of the Moon on the Earth (e.g., magnetic field, polarization
of light) are non-existent.
The logical consequence of such evidence is that none of these e ects appear in physics and
biology reference handbooks. However, many of these beliefs are deeply ingrained in both agricultural
traditions and collective imagery. This shows that more research should be undertaken on the possible effects observed on plants and assigned to the Moon by the popular belief, addressing their causes,
if any. It would also be interesting to address these issues in both compulsory education and formal
higher agricultural education in order to address pseudo-scientific ideas and promote critical thinking.

Yes science doesn't have all the answers and has no wisdom as it is based on testing hypotheses.It is always better to know what thoughts there are and what is published on views you don't share as it allows you to believe wih more vigour when can consider things from all sides.
