All — deficient in minerals, poor digestibility, and poor in crude protein ✓

Correct Answer: D

Explanation in English

Correct Answer: All the above

Parameter	Status in Straw/Stovers
Minerals (Ca, P)	Deficient — but rich in silica
Crude Protein / DCP	Very poor (DCP ≈ 0% in wheat straw)
Digestibility	Low (~46%)
Crude Fibre	Very high
TDN	Low (~40%)
Silica	Rich — inhibits digestibility

Improvement

Urea treatment: DCP 0→4–5%, TDN 40→50%, Digestibility 46→70%. Also: alkali treatment (NaOH), silage making, legume supplementation.
