Explore key concepts, techniques, and challenges in modern wheat yield improvement. This quiz covers genetics, agronomy, technology, and environmental impact in wheat agriculture.
Which breeding method is commonly used to increase wheat yield by combining traits from different varieties?
Explanation: Hybridization combines desirable traits from different wheat varieties to create improved strains with higher yield potential. Monocropping refers to growing a single crop repeatedly, which does not inherently increase yield. Crop rotation helps with soil health but is not a breeding method. Selective logging is unrelated to agriculture.
How does balanced fertilizer application contribute to higher wheat yields?
Explanation: Balanced fertilizers supply vital nutrients like nitrogen, phosphorus, and potassium, promoting healthy plant development and higher yields. Fertilizers do not primarily target weeds, provide shade, or directly increase soil water content.
Which irrigation technique helps optimize wheat yield while conserving water in arid regions?
Explanation: Drip irrigation delivers water precisely to plant roots, maximizing efficiency and yield, especially in water-scarce areas. Flood irrigation often leads to wastage, rain-fed only systems are less reliable, and no irrigation limits yield in arid environments.
Why is disease-resistant wheat important for yield improvement?
Explanation: Disease-resistant wheat minimizes yield losses caused by fungal, viral, or bacterial diseases. It does not affect soil acidity, pollination, or the ease of harvesting directly.
How does conservation tillage help sustain wheat yields over time?
Explanation: Conservation tillage maintains soil structure, reduces erosion, and enhances moisture retention, supporting consistent yields. It does not decrease sunlight, increase herbicide need, or lower seed germination when managed correctly.
