All questions of Agriculture for BPSC (Bihar) Exam

The correct answer is d) Neither of them.

Explanation:

The given matches between colors and agricultural productions are incorrect. Here are the correct matches:

1. Silver - Cotton Production
2. Yellow - Corn Production
3. White - Milk Production or Poultry Production

Therefore, none of the given options are correctly matched.

Drip Irrigation:

Drip irrigation is a type of micro-irrigation system that involves dripping water onto the soil at very low rates from a system of small diameter plastic pipes fitted with outlets called emitters. It is used to water crops in small areas or where water is scarce.

Statement Analysis:

1. Drip irrigation is also called Sprinkler irrigation and involves dripping water onto the soil at very low rates from a system of small diameter plastic pipes fitted with outlets called emitters.

This statement is incorrect. Drip irrigation and sprinkler irrigation are two different types of irrigation systems. Sprinkler irrigation involves spraying water over the crops, while drip irrigation involves dripping water onto the soil at very low rates.

2. Water is applied close to plants so that only part of the soil in which the roots grow is wetted.

This statement is correct. Drip irrigation is designed to apply water directly to the roots of the plants, which helps to minimize evaporation and water waste. By applying water close to the plants, only the soil in which the roots grow is wetted, which helps to conserve water.

Conclusion:

Therefore, the correct answer is option B, which states that statement 2 only is correct.

Understanding Organic Farming
Organic farming is a holistic approach to agriculture that emphasizes sustainability and environmental health. The statements provided in the question accurately reflect the principles of organic farming.
Statement 1: Production of All Organic Products
- Organic farming is indeed a production system that includes a wide range of agricultural products, not limited to fruits and vegetables but also extending to meat and eggs.
- Animals raised in organic systems must be fed organic feed and cannot be given antibiotics or growth hormones, ensuring that all products meet organic standards.
Statement 2: Local Resource Utilization
- Organic farming emphasizes the use of local resources, reducing reliance on imported inputs like synthetic fertilizers and pesticides.
- This practice enhances the resilience of the farming system and supports local biodiversity and ecosystems.
Conclusion
Both statements are correct as they encapsulate the essence of organic farming:
- It covers various agricultural products, including meat and eggs.
- It relies primarily on local resources, promoting sustainability.
Thus, the correct answer is option 'C', as both statements accurately portray the principles of organic farming.

Clean Tillage is a type of tillage practice in agriculture where the soil of the entire field is worked in such a way that no living plant is left undisturbed. This process is done to control weeds, soil-borne pathogens, and pests. The process of clean tillage involves several steps, which are discussed below:

Steps involved in Clean Tillage:

1. Preparing the Field: Before starting the clean tillage process, the field is prepared by removing any debris or plant residues left after the previous crop. This is done to ensure that the soil is free from any obstacles that may interfere with the tillage process.

2. Plowing the Soil: The next step involves plowing the soil using a plow or a disc to loosen the soil and make it ready for planting. This process also helps to mix any remaining plant residues with the soil, which will eventually decompose and add nutrients to the soil.

3. Harrowing the Soil: After plowing, the soil is harrowed to break up any large clumps of soil and to create a level seedbed. This process also helps to incorporate any remaining plant residues into the soil.

4. Seeding or Planting: Once the soil is prepared, seeds or seedlings are planted according to the crop being grown.

Benefits of Clean Tillage:

1. Weed Control: Clean tillage helps to control weeds by disturbing the soil and burying weed seeds that may be present on the surface.

2. Pest Control: Tillage helps to control pests by disturbing their habitat and exposing them to predators and other natural enemies.

3. Soil-borne Pathogen Control: Clean tillage helps to control soil-borne pathogens by burying any infected plant residues that may be present on the surface.

4. Improved Soil Structure: Tillage helps to improve soil structure by loosening compacted soil and creating a better environment for plant growth.

5. Nutrient Management: Tillage helps to mix plant residues into the soil, which eventually decompose and add nutrients to the soil.

In conclusion, Clean Tillage is an important tillage practice in agriculture that helps to control weeds, pests, and soil-borne pathogens while improving soil structure and nutrient management.

Explanation:
Tropical crops are crops that are grown in tropical regions of the world. These regions have a warm and hot climate which is suitable for the growth of such crops. Some examples of tropical crops are:

1. Bananas
2. Pineapples
3. Mangoes
4. Coffee
5. Cocoa
6. Rubber
7. Tea

Therefore, statement 1 is correct. However, statement 2 is incorrect as potato is not a tropical crop. Potatoes are grown in temperate regions of the world such as Europe and North America.

Hence, the correct answer is option B.
