CRDI 2 Cotton (Mc Nair 220): Yield, Maturity and Characteristics
CRDI 2 is a registered cotton variety, also sold or known as Mc Nair 220. It was registered with the National Seed Industry Council in 1994 as NSIC 1994 Ct 05. Cotton Research and Development bred it. It takes about 113 days from sowing to harvest, with 2.12 tonnes per hectare on average in the trials.
The average and top yields in tonnes per hectare come from the trials each variety went through to be registered with the NSIC, and from what the seed companies say about their own seed.
What farmers harvest today can be different. Newer harvest records, the season, the place, the soil, the water and the care all move these numbers over time.
So use them to compare varieties, not as a promise for your field. Ask your seller or your agriculturist how the variety did on farms near you in the last few seasons.

How long does it take, and how much does it yield?
CRDI 2 cotton takes about 113 days from sowing to harvest. That is 6.5 days faster than the average of the 7 cotton varieties with a day count, 119.5 days. A shorter crop frees the field sooner and dodges more of the weather, while a longer one often fills more.
Its average yield of 2.12 t/ha matches the average of its group, 2.15. Trial yields come from well managed plots, so your own will depend on water, fertilizer, pests and timing.
