Crop Production - JSS3 Agricultural Science Past Questions and Answers - page 2
Which of the following is an example of a perennial crop?
Wheat
Rice
Banana
Maize
What is the primary focus of crop production?
Maximising soil erosion
Enhancing water pollution
Cultivating and harvesting crops
Reducing agricultural productivity
What role do annual crops play in agriculture?
They require two growing seasons
They complete their life cycle within one growing season
They are primarily grown for direct human consumption
They contribute to the economic income of farmers
Why is it important for farmers to consider soil conditions?
To determine crop colour
To evaluate market demand
To assess wind speed
To make informed decisions regarding crop selection
What is the significance of the flowering stage in crop growth?
It marks the beginning of the growing season
It involves the formation of seeds or fruits
It signifies the completion of the life cycle
It occurs before germination
What is the primary purpose of crop production?
Crop production is primarily aimed at cultivating and harvesting crops for various purposes, including human and animal consumption, industrial use, or other applications. It involves a systematic process to ensure optimal yield, quality, and sustainability of crops, contributing significantly to food security, economic growth, and livelihoods.
How are crops classified based on their life cycle?
Crops are classified based on their life cycle into three main categories: annuals, biennials, and perennials. Annual crops complete their life cycle within one growing season, biennials require two growing seasons, and perennials have a lifespan extending beyond two years. This classification helps farmers plan crop rotations, select suitable varieties, and manage cultivation practices effectively.
What factors affect crop growth?
Several factors influence crop growth, including environmental factors such as temperature, light, water availability, soil conditions, nutrient levels, and pest management. Understanding and managing these factors are crucial for farmers to achieve optimal crop yields and quality.
What are the stages of crop growth?
Crop growth occurs in distinct stages, including germination, vegetative growth, flowering, fruiting, and maturity. Each stage has specific requirements and management practices. Monitoring the stages of crop growth allows farmers to implement timely interventions, such as irrigation, fertilisation, and pest control, to optimise yield and quality.
Why is it essential for farmers to understand the life cycle of crops?
Understanding the life cycle of crops helps farmers make informed decisions regarding crop selection, planting times, and cultivation practices. It allows them to plan crop rotations effectively, manage resources efficiently, and mitigate risks associated with environmental factors and pest pressures. By aligning farming practices with the life cycle of crops, farmers can optimise productivity, sustainability, and profitability.
