Introduction

Harvesting and storage are the final but equally important stages of crop production. Proper harvesting methods, safe storage practices, and knowledge of animal husbandry help farmers reduce losses and improve productivity. This practice set focuses on these important NCERT concepts through carefully designed MCQs with detailed explanations.

What You Will Learn

✔ Harvesting methods

✔ Threshing and winnowing

✔ Safe storage of grains

✔ Animal husbandry

✔ Crop protection

✔ NCERT concept-based practice

✔ Exam-oriented revision

Why This Topic Is Important

A good harvest is useful only when crops are properly processed and stored. Poor storage can lead to damage caused by insects, moisture, fungi, and rodents. Understanding harvesting, storage, and animal husbandry helps students appreciate scientific farming techniques and prepares them for examination-based questions.

1. MCQ Questions with Detailed Solutions

Q1. What is the process of cutting mature crops called?

A) Sowing

B) Irrigation

C) Harvesting

D) Threshing

Answer

C) Harvesting

Concept Behind This Question

Harvesting is performed only after crops become fully mature.

Step-by-Step Solution

When crops are fully grown and ready for collection, they are cut from the field. This process is called harvesting. Farmers may use a sickle or harvesting machines for this purpose.

Therefore, the correct answer is C.

Exam Tip

Harvesting = Cutting mature crops.

Q2. Which process separates grains from the harvested stalks?

A) Irrigation

B) Threshing

C) Ploughing

D) Sowing

Answer

B) Threshing

Concept Behind This Question

Threshing is done after harvesting.

Step-by-Step Solution

During threshing, grains are separated from the cut stalks and straw. It may be done manually, by animals, or with machines such as threshers and combine harvesters.

Therefore, the correct answer is B.

Exam Tip

Threshing = Grain Separation

Q3. Which method is commonly used to separate lighter husk from heavier grains using wind?

A) Composting

B) Weeding

C) Winnowing

D) Irrigation

Answer

C) Winnowing

Concept Behind This Question

Winnowing uses the difference in weight between grains and husk.

Step-by-Step Solution

During winnowing, the grain-husk mixture is dropped from a height. The lighter husk is blown away by the wind, while the heavier grains fall straight down.

Therefore, the correct answer is C.

Exam Tip

Winnowing = Wind separates husk from grains.

Q4. Which of the following conditions is most suitable for storing grains safely?

A) High moisture

B) Damp storage room

C) Dry and clean storage place

D) Open field

Answer

C) Dry and clean storage place

Concept Behind This Question

Moisture is one of the biggest causes of grain spoilage.

Step-by-Step Solution

Grains should be dried properly before storage and kept in clean, dry places. This prevents damage caused by fungi, bacteria, insects, and moisture.

Therefore, the correct answer is C.

Exam Tip

Dry grains remain safe for a longer time.

Q5. Which branch of agriculture deals with the rearing of useful farm animals?

A) Horticulture

B) Forestry

C) Animal Husbandry

D) Floriculture

Answer

C) Animal Husbandry

Concept Behind This Question

Animal husbandry is an important part of agriculture.

Step-by-Step Solution

Animal husbandry involves the scientific breeding, feeding, and care of domestic animals such as cows, buffaloes, goats, sheep, and poultry for useful products like milk, eggs, wool, and meat.

Therefore, the correct answer is C.

Exam Tip

Animal Husbandry = Scientific care of farm animals.
