With reference to 'Granaries', consider the following statements: 1. They are used for storing harvested grains. 2. They are designed to expose grains to moisture and pests to accelerate ripening. 3. They are used for the production of manure. Which of the statements given above is/are correct?

The correct option is (a). Explanation Granaries are agricultural structures used for the bulk storage of threshed grain. Proper storage is a critical phase in post-harvest management to ensure food security and prevent losses due to environmental factors or pests. - Statement 1 is Correct: The primary function of a granary is to store harvested grains (such as wheat, rice, or maize) safely for future use or sale. This helps in maintaining the supply of food grains throughout the year. - Statement 2 is Incorrect: Granaries are designed to protect grains from moisture, rain, and pests (such as rodents and insects). Exposure to moisture promotes the growth of fungi and bacteria, leading to spoilage and germination, rather than ripening. Grains must be dried before storage to reduce moisture content. - Statement 3 is Incorrect: Manure is an organic substance obtained from the decomposition of plant or animal waste (like cow dung). It is typically produced in compost pits or piles, not in granaries. Granaries are strictly for the storage of dry produce. Key Takeaway: Granaries are storage facilities designed to keep harvested grains dry and safe from pests; they are not involved in the production of manure or the acceleration of ripening through moisture exposure.

Solution

The correct option is (a).

Explanation

Granaries are agricultural structures used for the bulk storage of threshed grain. Proper storage is a critical phase in post-harvest management to ensure food security and prevent losses due to environmental factors or pests.

Statement 1 is Correct: The primary function of a granary is to store harvested grains (such as wheat, rice, or maize) safely for future use or sale. This helps in maintaining the supply of food grains throughout the year.
Statement 2 is Incorrect: Granaries are designed to protect grains from moisture, rain, and pests (such as rodents and insects). Exposure to moisture promotes the growth of fungi and bacteria, leading to spoilage and germination, rather than ripening. Grains must be dried before storage to reduce moisture content.
Statement 3 is Incorrect: Manure is an organic substance obtained from the decomposition of plant or animal waste (like cow dung). It is typically produced in compost pits or piles, not in granaries. Granaries are strictly for the storage of dry produce.

Key Takeaway:

Granaries are storage facilities designed to keep harvested grains dry and safe from pests; they are not involved in the production of manure or the acceleration of ripening through moisture exposure.
