With reference to the agricultural practices, consider the following ...
- Statement 1 is correct: Intercropping involves growing different crops simultaneously within the same plot of land. This increases the yield and maximizes utilization of abiotic inputs, like efficient use of sunlight, water etc.
- Statement 2 is incorrect: Mulches are generally waste plant materials. In mulching, these plant materials are spread around the base of the crops. It protects the soil from erosion, reduces compaction from the impact of heavy rains ,conserves moisture, reducing the need for frequent waterings, maintains a more even soil temperature and prevents weed growth

Explanation:
Inter-cropping and mulching are two different agricultural practices used to maximize crop productivity and optimize land use. Let's understand each practice in detail:
Inter-cropping:
Inter-cropping is a method of growing two or more crops simultaneously within the same plot. This practice involves planting different crops in alternate rows or mixed patterns, allowing them to grow together and utilize resources efficiently. Inter-cropping offers several advantages, including:
- Increased crop diversity: Growing different crops together promotes biodiversity and reduces the risk of crop failure due to pests, diseases, or adverse weather conditions. It also provides a wider range of food, fodder, and other agricultural products.
- Efficient resource utilization: Inter-cropping helps in optimizing resource utilization, such as sunlight, water, nutrients, and space. Different crops have different growth patterns and resource requirements, so they can utilize resources more efficiently when grown together.
- Weed suppression: Some crop combinations in inter-cropping exhibit weed-suppressive properties. The dense growth of inter-cropped plants can shade out weeds, reducing the need for herbicides and manual weeding.
- Pest and disease management: Inter-cropping can disrupt pest and disease cycles by creating a less favorable environment for their survival and spread. Some crop combinations also exhibit natural pest-repellent properties.
Mulching:
Mulching is the practice of covering the soil surface with a layer of organic or inorganic material, such as straw, leaves, plastic, or stones. This layer acts as a protective barrier and offers several benefits, including:
- Moisture conservation: Mulching helps in reducing water evaporation from the soil surface, thus conserving moisture. It also helps in maintaining a more stable soil moisture level, especially during dry periods.
- Weed control: A mulch layer suppresses weed growth by blocking sunlight and preventing weed seeds from germinating. This reduces the competition for resources between weeds and crops.
- Soil temperature moderation: Mulching can regulate soil temperature by insulating the soil from extreme heat or cold. This is particularly beneficial for crops with temperature-sensitive roots.
- Soil erosion prevention: The mulch layer protects the soil from erosion caused by wind or water. It minimizes the impact of heavy rains and prevents soil particles from being washed away.
- Improved soil fertility: Organic mulches, such as compost or straw, gradually decompose and enrich the soil with organic matter, nutrients, and beneficial microorganisms. This improves soil fertility and enhances crop growth.
Conclusion:
Considering the given statements, only statement 1 is correct. Inter-cropping involves growing different crops simultaneously within the same plot, while mulching is the practice of covering the soil surface with a layer of organic or inorganic material.
