Apple-Crop: Apples at a place where there is no chilling.

2009-02-16 Thread Dr. Chiranjit Parmar
Dear all,

I was in Indonesia for two weeks and also visited some places in Java island of 
that country.  I had a VERY BIG SURPRISE of my life there.  In Batu area of 
Java I saw apples being cultivated.  This are is around 3000 ft above the seaas 
level, at 6 degrees south of equator.  The minimum temperature of this area is 
above 45 F meaning that the trees do not receive any chilling.  Most farmers 
even take two crops a year by regulating the flowering with pruning or hand 
defoliation.  The fruit quality is good and these fruits are bought by 
consumers at supermarkets at a price higher than that for Fuji apples.

I would not have believed it had I not seen these orchards personally.

Could any of you explain how these apple trees are able to grow and bear fruits 
even without meeting their chilling requirements?

Hello Dr. Parmar,

Just a suggestion, but production of ABA, which regulates dormancy, is
encouraged by shortening days and lengthening nights. At 6 degrees
south, daylength will not change, so I suspect that there might not be
so much ABA in the buds (especially if defoliation is practised), and so
they might not become dormant in the first place, and so the chilling is
not required to break dormancy.

That place sounds so amazing that I would love to go there some time to
see for myself.

Dr. Parmar:

Apples are cultivated in many tropical locations such as Honduras, Nicaragua, 
Uganda, and the Philippines.  The branches are trained horizontally and 
dormancy is triggered and broken most often by stripping the leaves off by hand 
to coincide with the onset of the dry season, when any irrigation is also shut 
off.  Dormancy-breaking chemicals like Dormex have been tried, but in most of 
these rural locations it is too hazardous and expensive to be used effectively 
and hand-stripping works better anyway. Because day lenght is relatively the 
same year round, this process can be used to harvest two to three crops with 
supplimental fertilization.

I recall 10 years ago getting a report from missionaries from Wycliffe Bible 
Translators who were helping set up some Honduran indiginous group with a cider 
press for a home-based industry, and they were doing quite well.  It was funny 
to see an old-fashioned cider press in the jungle. A Vermont-based group called 
Farmer to Farmer was also helping set up apple processing like jams and apple 
butter.

In 2005 the fledgling apple industry in Uganda was the subject of an intensive 
studay you can download at www.icra-edu.org/objects/public_eng/ACFRUkhMi.pdf   
This report is the basis for my export of 200 apple trees to Rwanda the end of 
this week, with requests from Congo and Kenya pending.  My small nursery is 
based on experimenting with varieties to find those suitable for high-heat, 
low-chill applications for warm climates, and the top varieties may raise some 
eyebrows.  You are of course with Anna and Dorsett Golden, but we are also 
favoring those that color up well despite hot nights like Arkansas Black and 
Williams' Pride, which is disease-resistant as well, a plus in tropic 
conditioins.  It has responded to leaf-stripping culture quite readily.  There 
is definately a need for longer-keeping varieties for the tropics, as Anna only 
is good for a couple weeks after picking.

I'm pleased with the high prices the Bantu apples are fetching, as one of the 
main problems facing rural farmers in Southeast Asia are competition from cheap 
Chinese imports, which even in rural markets can beat out local competition.  
The quality is of course poor and so good-tasting local produce would have an 
edge.  I would like to see some photos if you have them.  Thanks for posting 
your report.
