I am so ignorant to grafting so I don't think I will be pioneering this method haha.
Future, if you try please lettuce know
Thanks for the encouragement on inga, will do a trial this week when they get a "chop and drop" without drop haha!
Have anyone noticed any difference in response for Durio zibethinus with a companion plant? Like Inga sp, gliricida sp, Fabace sp. etc.
I know Douglas Fir does well with alder as the alder shares it's fixed N with the DF and the DF shares something else back. Through mychorizea.
I read about the DF and Alder in Suzan Simmards book, "Finding the mother tree" and immedietly started to question what tree's grow naturally among druians and would any of them connect to the same MR (mychorizea) and share nutrients.
I want to do a field experiment but it's very hard to get enough keranji and petai seeds.
Anyone who want's to sell or barter them please PM
It seams like Dialium indum Keranji, Parkia speciosa Petai appear in the same forest as most Durio sp. "Mixed Lowland dipterocarp and Riverine Forest"
According to Anthony lamb in "A guide to wild fruits of Borneo"
Both of those are in the Fabaceae family.
I have a feeling that there is an amazing amount of knowlage that can increase yeilds and long term sustainablity of our relation to Durian, we just haven't conucted enough experiments or observed well enough. This goes beyond providng fallen leafs and swigs for N incorporation into the soil by decay, it's a intentional funneling of N from one tree to another.
Both inga and gliricida are not from the same botanical original area as Durio so I don't know if they would be able to attach to the same mychorizea. I have never seen any mychorizea on durian roots so they might be in symbiosis with arbuscular mycho where I live or there's an absent of the correct spores??.
Anyone seen any ectomycorrhizal fungi on durian roots?
Have a 2000x microscope on order so will see if I can disect and find the AM. I know there is one research paper on the topic:
https://ejournal.forda-mof.org/ejournal-litbang/index.php/JPTH/article/view/5506I think pinto peanut and those ground cover's are good for the early years of esablishment but for maximum yields and growth there should probobly be a tree companion.
Durio Kutjensis is calssified as a understory tree at max 20/25m but D. zib and D. graveolens are classified as main canopy tree's on the richer clay soils reaching 40/50m in height accoriding to A lamb.
A condition with a symbiotic tree would probobly create the best possibilities for hight fruit quality and regular bearing, eliminating farm inputs on some soils and just the need to protect from mammals and birds.
Peter, have you seen a decline in tree growth in any tree when you chopped a gliricida close by etc??
Maybe that reduced the total N uptaken by the main crop tree.?
sorry for the spelling errors.
