I am really happy to have this forum.
Myself sanjay a wannabe farmer
I am on the verge of buying 4 acre land Karkala, Karnataka . Have been interested in natural organic farming .
I would like to grow in five layer Panchantarangini model:-
Macadamia
Lemon/nutmeg/
Mango (hybrid small one)
Avocado(spruning)
And turmeric/ ginger / bush pepper/ chilly/ with some beans / pigeon peas etc

I would really be happy if experts/ professionals of the forum give their opinion on suitability of chosen crop to the region and weather this model can be developed or not

Alternately I am also thinking of rambutan / cocunut
Guava /coco
Mangostein
Arecanut
Banana
Avocado
Final layer the same as above
