Explanation

• Hydroponics is a soilless cultivation system where plants grow in nutrient-rich water.
• Requires water, dissolved fertilizers, and light for growth.
• Soil is not used; plants are supported by inert media or water alone.

• Puccinia recondita is a fungus that causes leaf rust in wheat, leading to yellow-orange pustules on leaves.
• It reduces photosynthesis and crop yield if not controlled.

Additional information:

• Leaf Blight – Alternaria triticina
• Smut – Ustilago tritici
• Powdery Mildew – Blumeria graminis
• Karnal Bunt – Tilletia indica

Explanation

• Goals are the desired outcomes or objectives toward which efforts and actions are directed.
• They provide direction, motivation, and a framework for planning.

Additional information:

• Clear goals help in resource allocation and performance evaluation.
• In agriculture, goals could include higher crop yield, pest control, or efficient water use.

Explanation

• Rainfed areas depend entirely on rainfall for crop growth.
• The main problem is irregular or insufficient rainfall, leading to water scarcity for crops.

Additional information:

• Farmers in rainfed areas often use drought-resistant crops and soil moisture conservation techniques to cope with water scarcity.

Explanation

• Sprinkler irrigation applies water uniformly like rainfall using pipes and sprinklers.
• It is most suitable for undulating or uneven land where flood irrigation is difficult.

Additional information:

• Sprinkler irrigation is also efficient in water use.
• It can be used for high-value crops like vegetables, cotton, and maize.

Explanation

• Apiculture is the practice of rearing honeybees for honey and wax production.
• Helps in pollination and increasing crop yields.
• Honey, beeswax, and propolis are valuable products from apiculture.

• Sericulture → Rearing of silk worms.
• Silviculture → Cultivation of trees and forests.
