Hi Muhammad,

What kind of data your going to search. Precision agriculture  is a wast domain. What kind of problem your going to address and domain are things in which you have to decide. 

Is it to identify disease of plant or medical plant  analysis .  You can find few medical leaf database like FLAVIA which is freely available 

It depends what your question is ?  If you find some data sets please share them.  We are offering a course this year and need more data.

Another one's link  I found, named as Herbarium Dataset

Infact I need Image datasets

Image dataset of which plant or fruit?

Just images or what do you expect to be marked?

Here is a reference that you may find useful.

Please let me know if I can assist in any way.
