खालीलपैकी कोणते उपयोजन हे दूरस्थ संवेदन प्रणाली द्वारे करू शकतो ?
(a) कृषि पाणी व्यवस्थापन
(b) पीक प्रणाली विश्लेषण
(c) बागायती पीक क्षेत्र अंदाज आणि देखरेख
(d) पीक क्षेत्र आणि उत्पादन अंदाज
(1) (a), (b) आणि (c)
(2) (b), (c) आणि (d)
(3) (a), (b) आणि (d)
(4) (a), (b), (c) आणि (d)

The correct answer is Option D ((a), (b), (c) and (d)).

Key Points:
• Agricultural Remote Sensing: Satellite remote sensing analyzes spectral reflectance characteristics of crop canopies using multispectral sensors.
• Agricultural Applications:
• Water Management: Soil moisture estimation, canal command area scheduling, and evapotranspiration mapping (Statement a).
• Cropping System Analysis: Multi-date imagery tracking crop rotations, cropping intensity, and fallow cycles (Statement b).
• Horticultural Monitoring: Flagship programmes like CHAMAN (*Coordinated Horticultural Assessment and Management using geoiNformatics*) estimate acreage under mangoes, citrus, potatoes, etc. (Statement c).
• Crop Forecasting: The FASAL (*Forecasting Agricultural output using Space, Agro-meteorology and Land-based observations*) project performs pre-harvest acreage and yield forecasts (Statement d).
• Official Key: All four applications are executed via remote sensing (Option 4).
• Key Takeaway: Remote sensing enables agricultural water planning, cropping pattern analysis, horticulture monitoring, and pre-harvest crop forecasts.
