Explore key issues affecting cotton crop production, from pests to water requirements, through real-world scenarios and practical questions. Enhance your understanding of agricultural challenges unique to cotton farming.
Which pest is most commonly known to cause significant yield loss in cotton crops worldwide?
Explanation: Bollworm is a major pest for cotton, damaging bolls and reducing yields globally. Root Maggot primarily affects root crops rather than cotton. Leaf Miner prefers vegetable crops, while Soybean Looper primarily targets soybean plants.
During which stage does cotton require the most water for optimal growth?
Explanation: Cotton plants have the highest water demand during flowering and boll formation due to rapid growth. Seedling establishment needs less water, dormancy requires minimal, and harvesting comes after major water use has peaked.
What type of soil is least suitable for cotton cultivation due to poor drainage and high clay content?
Explanation: Heavy clay soils retain too much water, leading to poor drainage and root diseases in cotton. Sandy loam and alluvial soils drain well and suit cotton, while red soils, though not optimal everywhere, are generally better than heavy clay.
A sudden unseasonal frost during early growth of cotton is most likely to cause what issue?
Explanation: Unseasonal frost can delay cotton seed germination and reduce plant establishment rates. Increased boll set and improved fiber quality are not effects of frost, while reduced leaf area could occur but is less critical than germination delay.
Why is timely weed control particularly important during the first 60 days after planting cotton?
Explanation: Early in the season, cotton plants grow slowly, giving fast-growing weeds a competitive advantage for resources. Mature cotton cannot suppress weeds chemically, weed seeds can germinate at various times, and insect feeding patterns are unrelated.
