Explanation

• Safe moisture content is the level at which stored rice remains safe from spoilage.
• For rice, it is 12–14%.
• Proper moisture prevents fungal growth, insects, and quality loss.

Additional information:

• Moisture above 14% may cause mold and deterioration.

Explanation

• Safe moisture content refers to the moisture level at which stored wheat remains safe from spoilage.
• For wheat, it is 8–10%.
• Proper moisture prevents fungal growth and insect damage.

Additional information:

• Moisture above 10% can cause mold and loss of quality.

Explanation

• Wheat is a cereal crop, not an oilseed crop.
• Sunflower, soybean, and cotton are oilseed crops used for edible oils.
• Oilseed crops are grown primarily for oil extraction from seeds.

Explanation

• Potato is highly sensitive to soil salinity, which affects germination, growth, and tuber formation.
• Saline soils reduce water uptake and nutrient absorption in potatoes.

Additional information:

• Management includes soil leaching, proper irrigation, and salt-tolerant varieties.
• High salinity can lead to stunted growth, leaf burn, and reduced yield.

• The adoption process describes the stages a farmer or individual goes through before fully adopting a new technology, practice, or innovation.

Steps include:

1. Awareness: Learning about the new idea or technology.
2. Interest: Developing curiosity and seeking more information.
3. Evaluation: Considering pros and cons of adoption.
4. Trial: Testing the innovation on a small scale.
5. Adoption: Full-scale implementation after positive results.

Explanation

• Hybrid seed development involves creating seeds from two genetically distinct parent lines to produce high-yielding, uniform crops.

Steps include:

• Selection of parent lines: Choose plants with desirable traits like disease resistance and high yield.
• Controlled pollination: Ensure pollen from one parent fertilizes the other to maintain hybrid purity.
• Seed production and multiplication: Increase quantity while preserving genetic characteristics.

Last verified on 31-01-2026

Explanation

• Seed multiplication is the process of increasing seed quantity through successive stages to maintain quality and purity.

Stages include:

• Breeder seed production: Highest genetic purity, developed by plant breeders.
• Foundation seed production: Produced from breeder seed, retains genetic purity.
• Certified seed production: Produced from foundation seed, distributed to farmers.

Explanation

• Hollow cone nozzles produce a fine, circular spray pattern ideal for uniform coverage of leaves and plants.
• Commonly used for insecticides, fungicides, and herbicides in crops like cotton, vegetables, and fruit trees.
• Ensures better penetration into dense foliage, improving pest control efficiency.
