Crop Production Management (Manure, Fertilisers, Irrigation) MCQs

Q1. A village farmer fills a pit with cattle dung, leftover straw and kitchen peelings and lets the heap rot for months before spreading it on the field; what is the product he spreads called?

• A.Pesticide
• B.Chemical fertiliser
• C.Weedicide
• D.Manure

Answer: D. Manure

Manure is decomposed organic matter from animal dung, urine and plant residues. Rotting farm waste in a pit yields manure, not a manufactured fertiliser.

Q2. A shopkeeper sells a sack labelled 'urea, 46% nitrogen' that was produced in a chemical plant; into which category of soil input does this sack belong?

• A.Inorganic fertiliser
• B.Compost
• C.Green manure
• D.Organic manure

Answer: A. Inorganic fertiliser

Urea is a synthetic nitrogenous compound made in factories, so it is an inorganic (chemical) fertiliser rather than a natural manure.

Q3. Two soil inputs are compared: the first is bulky, dark and crumbly from a rotting pit, the second is a fine white crystalline powder from a bag; which one is the manure?

• A.Both of them equally
• B.Neither of them
• C.The bulky dark crumbly material from the pit
• D.The fine white crystalline powder

Answer: C. The bulky dark crumbly material from the pit

Manure is decomposed organic waste and is typically bulky, dark and crumbly. The bagged crystalline powder is a concentrated chemical fertiliser.
