FAQs on Index: Strategies for Enhancement in Food Production - Biology for Grade 12

1. What are some strategies for enhancing food production?
Ans. Some strategies for enhancing food production include crop rotation, use of high-yielding varieties, proper irrigation and water management, organic farming techniques, and integrated pest management. These strategies help to increase crop yield, improve soil fertility, conserve water resources, and reduce the use of chemical fertilizers and pesticides.
2. How does crop rotation enhance food production?
Ans. Crop rotation is a strategy where different crops are grown in a sequence on the same piece of land over a period of time. It helps in enhancing food production by reducing the build-up of pests and diseases specific to a particular crop. Crop rotation also helps in improving soil fertility as different crops have different nutrient requirements and leave behind residues that enrich the soil.
3. How do high-yielding varieties contribute to food production?
Ans. High-yielding varieties (HYVs) are crop varieties that have been selectively bred to produce higher yields compared to traditional varieties. These varieties have traits such as disease resistance, improved nutrient uptake, and shorter maturity period. HYVs contribute to food production by increasing crop yields per unit area, thus ensuring food security for a growing population.
4. What is integrated pest management (IPM) and how does it enhance food production?
Ans. Integrated pest management (IPM) is an approach that combines various pest control strategies to minimize the use of chemical pesticides. It involves the use of biological control agents, crop rotation, trap crops, and cultural practices to manage pests effectively. IPM enhances food production by reducing pest damage, minimizing the negative impact on the environment, and improving the quality of agricultural produce.
5. How does proper water management impact food production?
Ans. Proper water management plays a crucial role in enhancing food production. It involves efficient irrigation techniques, such as drip irrigation and sprinkler systems, which help in delivering water directly to the plant roots, minimizing water loss through evaporation. Additionally, water management includes the conservation and storage of water through measures like rainwater harvesting and the use of water-efficient practices. By ensuring adequate water supply and reducing water wastage, food production can be increased sustainably.
