Step 1: Understanding Vermiculture.
Vermiculture is the process of cultivating worms, particularly earthworms, to decompose organic waste and convert it into nutrient-rich compost. This is an effective method for producing organic fertilizer.
Step 2: Analyzing the options.
(A) Vermiculture: Correct — Vermiculture specifically involves the cultivation of worms for organic waste decomposition.
(B) Sericulture: Sericulture refers to the cultivation of silkworms for silk production, not for composting organic waste.
(C) Pisciculture: Pisciculture is the breeding and rearing of fish, not related to organic waste management.
(D) Arboriculture: Arboriculture refers to the care and management of trees, not the cultivation of worms.
Step 3: Conclusion.
The correct answer is (A) Vermiculture, as it involves the use of worms to convert organic waste into fertilizer.
