Jackfruit Brix

I got a reading of 38.2 on my NS1. Seems high. What's a normal brix read on a jack?

Wow, that’s very high. Was there a lot of bits or pulp that may have affected the refraction of light? Did it taste super sweet like a Sapodilla?

It was insanely sweet to the taste, the entire fruit. I've been trying different fertilization regimens and comparing results. In this particular case, I gave the tree a boatload of  slow-release nitrogen, which seems to have upped the brix. In general, more N has seemed to mean more brix on most of my fruits. I think it must permit better Ca uptake.

Funny, I too am experimenting while nitrogen this grafted Excalibur red was dormant all last year, no growth even some die back. Few weeks ago fertilized my lawn with vigoro 29-0-2 and being on tilt about this tree threw a hefty amount of the grass fertilizer on it and cut off the die back. Looks like it’s jolted into growth finally.
