जैसे ही आप प्रश्नोत्तरी लेते हैं उत्तर और स्पष्टीकरण दिखाई देते हैं।

1. Which four spectral bands are typically included in USDA Farm Service Agency four-band imagery?
   • Red, green, blue and near-infrared
   • Ultraviolet, X-ray, thermal and radar
   • Only red and near-infrared
   • Blue, ultraviolet, microwave and lidar
2. जॉन डीयर सी एंड स्प्रे शाकनाशी के उपयोग को कैसे कम करता है?
   • पूरे खेत में समान रूप से छिड़काव करके
   • केवल ज्ञात खरपतवारों का छिड़काव करने के लिए कंप्यूटर विज़न का उपयोग करें
   • सभी शाकनाशियों पर प्रतिबंध लगाकर
   • केवल रात्रि में छिड़काव करने से
3. परिशुद्ध कृषि में 'परिवर्तनीय-दर प्रौद्योगिकी' क्या है?
   • किसानों से बीज के अलग-अलग दाम वसूल रही है
   • ट्रैक्टर की गति को बेतरतीब ढंग से बदलना
   • विभिन्न फ़ील्ड ज़ोन में अलग-अलग मात्रा में इनपुट लागू करना
   • एक प्रकार का फसल बीमा
4. Which model architecture did the cited 2025 crop-weed paper evaluate for edge weed detection?
   • A speech-recognition Transformer
   • A rule-only spreadsheet parser
   • A large language model trained on contracts
   • A lightweight convolutional neural network
5. In the USDA ERS 2023 report, variable-rate technology had been adopted on what share of planted acreage for winter wheat, cotton, sorghum and rice?
   • Between 5 and 25 percent
   • Less than 1 percent for every crop
   • Between 50 and 75 percent
   • All planted acreage
6. What did the cited USDA precision-farming field study report about yield patterns across years?
   • Yield patterns were identical every year
   • Yield patterns changed yearly and had little similarity between years
   • All management zones produced the same yield
   • AI consistently improved yield in every zone
7. How is NDVI commonly calculated from red and near-infrared reflectance?
   • Red plus blue divided by soil moisture
   • Thermal radiation minus wind speed
   • Near-infrared minus red, divided by their sum
   • Plant height multiplied by fertilizer rate
8. Why can variable-rate technology use input maps instead of a single field-wide rate?
   • Every part of a field has identical needs
   • Maps eliminate the need for agronomic decisions
   • The system changes crop genetics while spraying
   • Soil and crop conditions can vary across zones within a field
