Explore key aspects of capsicum growth techniques in horticulture, covering soil, watering, temperature, fertilization, and pest management. Designed for learners seeking to strengthen their foundational knowledge in efficient capsicum cultivation.
Which soil type is most suitable for optimal capsicum growth in agricultural production?
Explanation: Well-drained loamy soil provides a balanced texture, good aeration, and sufficient moisture retention for capsicum. Heavy clay soils retain too much water and inhibit root development, while very sandy soils hold too little moisture. Highly alkaline soils can cause nutrient deficiencies and are not ideal for capsicum.
What is the recommended frequency of watering capsicum plants for steady vegetative growth?
Explanation: Consistent, moderate watering keeps soil moist but not waterlogged, supporting healthy capsicum growth. Weekly watering is usually insufficient, daily flooding leads to root disease, and allowing soil to dry completely can stress the plants.
For successful capsicum fruit set, what is the ideal daytime temperature range during growth?
Explanation: Capsicum develops best and produces fruit optimally between 20°C and 30°C. Lower temperatures (10°C to 18°C, 5°C to 10°C) inhibit growth and flowering, while extremely high temperatures (35°C to 40°C) can reduce fruit set and cause blossom drop.
When is the most effective time to apply nitrogen-based fertilizer to capsicum plants?
Explanation: Applying nitrogen during the vegetative stage encourages strong plant growth necessary for later fruiting. Applying only after harvest or at full maturity provides little benefit, and after flowering is often too late for significant impact.
What is one common organic technique used for managing aphids on capsicum crops?
Explanation: Introducing ladybird beetles is an effective organic control since they are natural predators of aphids. Salt water can harm the plants, synthetic insecticides are not organic, and burning is destructive and unnecessary.
