Explore key techniques in modern crop growth and management with this medium-difficulty quiz. Deepen your understanding of sustainable and effective agricultural practices.
Which crop growth technique improves soil structure and nutrient content before sowing seeds, often using examples like plowing or adding compost?
Explanation: Soil preparation, such as plowing or compost application, enhances soil qualities for better crop establishment. Drip irrigation pertains to watering methods, not soil improvement. Pest scouting monitors pests rather than improving soil. Monocropping refers to growing a single crop type, unrelated to soil structure enhancement.
Which irrigation method delivers water directly to plant roots, reducing evaporation, and is suitable for water-scarce regions?
Explanation: Drip irrigation targets the roots, minimizing water loss and improving efficiency in dry areas. Flood irrigation wastes much water through surface runoff and evaporation. Broadcast irrigation is not a common term and may confuse water application techniques. Rain-fed agriculture relies on natural rainfall, lacking controlled irrigation.
What is the practice of growing different types of crops in sequential seasons on the same land to preserve soil nutrients and reduce pest buildup?
Explanation: Crop rotation alternates crops to balance nutrient use and disrupt pest cycles. Tillage is the mechanical preparation of soil. Greenhouse farming uses controlled environments, not necessarily varying crops. Hydroponics grows plants without soil, unrelated to seasonal crop changes.
Which sustainable pest control strategy combines biological, cultural, and chemical approaches to manage crop pests effectively?
Explanation: Integrated Pest Management (IPM) uses multiple tactics—biological, cultural, and limited chemicals—for sustainable pest control. Fumigation is a chemical-only method. Overhead sprinkling is an irrigation technique, not pest control. Stubble burning is a field clearing method and not a pest management strategy.
What is the term for adding nutrients to crops, either as synthetic compounds or organic matter, to enhance their growth and yields?
Explanation: Fertilizer application supplies nutrients to crops, supporting healthy growth and yield improvement. Grafting is a propagation technique, not directly related to feeding plants. Dehorning concerns livestock management. Aquaponics is a system integrating fish and plant cultivation, not a nutrient application method itself.
