Can a pinto bean grow faster then a black bean?

Are we talking sprout or full maturity?

All I could find was:

Pinto Beans

Plant Development Stages Stage 1, germination to a stand, occurs in about 4 to 8 days in warm soil. Stage 2, rapid vegetative growth, continues from emergence to about 28 to 32 days after planting. Stage 3, flowering and pod development, begins with the appearance of the first blossom at about 32 to 40 days after planting (28 to 32 days after emergence). Flowering and development of pods continues for the next 10 to 14 days to produce the seeds that will reach prime maturity. Stage 4, pod fill and maturation, occurs about 40 to 50 days after seeding and continues until 60 to 70 days after planting.

Drying of pods and foliage usually occurs between 70 and 90 days after planting on the High Plains. Time required for maturation and dry down depends on variety and weather.

Then:

Black Beans

Which are a bit tougher to find info on, and this is about the best I could come up with but both are reputable sites! They are also called Black Turtle Beans too. Odd name…

Black beans grow best at temperatures between 65 and 75 degrees F. They are a warm season crop, requiring up to 120 days to reach maturity and dry. The beans are left on the plants to dry, so humidity and heat can cause damage to the beans as they are drying on the plant, and rain can be a problem during the drying and curing process. They are harvested by machine, and the plants themselves left as ‘green manure’.

So, the Black Beans take longer to mature than the Pinto’s, but that is about the extent of it! Black Beans are listed with Pinto’s as they are both dried beans, so perhaps they sprout at about the same rate, and just mature at different rates.

That was a bit of a tough one ! LoL!
