Study Notes
Crop Planting Materials and Seed Viability
- Crop success hinges on quality planting materials. Proper selection ensures high-quality yields.
- Orchards start with variety selection matching location conditions.
- Seedlings remain the most economical planting material for fruit and tree crops.
- However, genetic variation among seedling-derived plants sometimes leads to unsatisfactory results.
- Growing plants depends on diverse planting materials suitable for specific climatic conditions (e.g., heavy rain, warm climate, low precipitation).
- Besides climate and soil, successful plant growth depends on the planting material's quality and root system.
- Planting methods include seeds, saplings (1-2 years old), and saplings with bare roots (1-2+ years).
Seed Planting and Agribusiness
- Agribusiness needs seed planting knowledge for good crop yields and harvest estimates.
- Superior yields depend on high-quality seeds.
- Seed testing before planting is crucial for crop management.
- Tested seeds save time, money, and labor.
- Farmers must test seed viability (ability to germinate).
- Characteristics of good seeds include physical/genetic purity, high germination rate, plumpness, and suitability to local conditions.
Seed Viability Testing
- Seed viability testing is essential for crop production.
- Testing methods: Seed box method and Rag doll method.
- Germination percentage calculation: (Number of germinated seeds / Number of seeds used) x 100%
Seed Scarification
- Some seeds prevent moisture penetration and thus don't germinate.
- Seed scarification (nicking & soaking) accelerates germination.
- This technique is useful for seeds with impermeable seed coats (e.g., beans, squash, patola) that require a cut to allow water penetration.
- Scarification steps: Carefully make a shallow cut, soak, then plant.
- Methods include physical, chemical, and thermal scarification.
