Crop Production I (Continued) - JSS2 Agricultural science Past Questions and Answers - page 2

Crop rotation is essential in agriculture as it helps maintain soil fertility, reduces pests and diseases, and enhances overall crop yield. By alternating different crops in a sequence, crop rotation prevents the depletion of soil nutrients specific to certain plants, promoting balanced nutrient availability for subsequent crops.

Crop yield in agriculture is influenced by various factors, including environmental conditions, soil fertility, pest and disease management, and crop husbandry practices. Favourable environmental conditions such as temperature, moisture, and sunlight promote healthy plant growth and development, ultimately impacting yield. Soil fertility, determined by nutrient availability and pH levels, directly affects crop productivity and quality.

Harvesting is a crucial stage in crop production, aiming to collect crops at their optimal stage of maturity to maximise yield and quality. Proper timing ensures that crops are harvested when they have reached peak nutritional content, flavour, and marketability. Harvesting at the right stage prevents over-ripening or underdevelopment, minimising yield losses and maximising market value.

Post-harvest practices are critical in agriculture as they help minimise losses, maintain crop quality, and ensure longer shelf life. Curing and drying methods remove excess moisture from harvested crops, preventing mould growth and spoilage during storage. Proper storage facilities, including warehouses and silos, protect crops from environmental factors such as temperature fluctuations, humidity, and pests.

Practical applications and case studies in crop production provide valuable insights into the principles and challenges involved in crop cultivation. Real-world examples illustrate the implementation of crop management practices, highlighting their effectiveness in addressing specific agricultural challenges. Case studies showcase innovative approaches, technologies, and best practices adopted by farmers to improve crop productivity, sustainability, and resilience.
