22 Summary For crops like Potato, Mango, Citrus and Banana use of remote sensing data for assessment have been feasible, but for other crops accuracy is still an issue, due to scattered and small fields, mixed cropping, multiple seasons and short duration. Yield estimation for horticultural crops, especially fruit crops, is a problem due to multiple picking. However use of satellite data and geospatial tools has shown a great promise for horticultural development, especially for infrastructure development and horticultural expansion.
