yield, crop, harvest

Hello everyone,
Now I've got mixed up with the words 'crop(s)', 'yield' and 'harvest'. Is there any difference between them?
Thanks in advance!

Post here what you think the definitions are, and what is confusing you?

Sorry for answering so late. My Internet connection has let me down.
I don't understand whether they are complete synonyms or not. Will the three sentences below have the same meaning (without a slightest difference)?
This year the yield/crop(s?)/harvest of fruit has been enormous in Sri Lanka.
Does the word 'crop' mean a smaller amount of harvest? Is 'yield' the most scientific word out of this threesome?
Thanks in advance.

In that sentence "crop(s)" is wrong. It would be OK with "yield" or "harvest" but with a change in the word order "This year the fruit harvest/yield has been enormous in Sri Lanka". I would use "was" rather than "has been".

Many thanks, dear bhaisahab. Could you please explain it to me why the word 'crop(s)' is wrong there, and what the difference in the use and meaning of harvest/crop/yield is?
