Is there somewhere I can find 10 day benchmarks for a field pumpkin that will end up between 75-125 pounds?

I sure wish there was a good benchmark to follow.
I have found some posts a year or so ago that mention 60" CC on day 20 is good. 10 pound Gains per day from D20 to D30 are also consider robust.

Shannons comment (that FPs grow for about 30 days, see previous topic) made me worry that mine could never become a big one, bit here it looks like good growth might still be possible on day 30 (thus making me look forward to a 30+++ days growth phase of my first FP).
Apparently, FPs have very diverse fruit growth habits (growing until day 30, or still being in peak growth mode on day 30). Therefrom I just conclude that day 10 doesn´t mean anything. It will much more depend on the FP you are growing (if it´s a 30- or a 45-day grower) and on weather (as they might grow slowly but for many more days if it isn´t too hot).

...bloody typos...happens again and again. In 1st line it must read BUT not BIT

Delaying senescence and keeping the sink growing is an inexact science we are all trying to figure out. Extending a FP growth curve a few more days or weeks is definitely possible in my opinion.

AGP's have a wide range of growth curves so why not FP's too.

Remembering the Richmond Lange effect will come in handy after day 30.

good Luck & good growing

In my experience temperatures play an important part in the growing length of both field pumpkins and their cousins, English marrows.

I have seen both stop growing within 30 days in hot temperatures and my WR marrow was still growing after 50 days during a relatively cool summer.

I agree Brad.

In hot temperatures canopy transpiration increases while stressing the developing fruit at the same time. Each stress event accumulates and builds upon another. The once adventitious roots begin to build suberin isolating them, the plant produces the ripening hormone ethylene and suddenly the growth curve plummets.

The effects of stress are senescence causing in and of themselves.

The plants natural reaction is in protecting the primary fruit sinks developing seeds and ultimately the next generation from the harsh elements.
