Question 1

What is the main purpose of the study on sorghum seeds?

Accepted Answer

To study sorghum seed development and assess how fertilizer dosage affects seed viability at different seed maturity stages.

Question 2

How were the experiments designed and what were the key treatment factors?

Accepted Answer

The study used a split-plot design with a completely randomized design: NPK fertilizer dose as the main plot and seed maturity stages as the subplot, repeated three times.

Question 3

At which day after anthesis does sorghum reach physiological maturity and what indicators support this?

Accepted Answer

Physiological maturity is reached at 35 days after anthesis, supported by maximum values of 1000-grain weight and seed vigor, with vigor not differing from 40 DAA.
