Did you try googling them up? 

High Yield Crops has two meanings.  It is crops that produce a greater ratio of food for input.  It can also mean production per land used.  A tree is a very high ratio!  One seed can make a tree that makes crops for a long, long time.  But it is not a high land use ratio because a tree takes a lot of space and usually produces only once per year.  So it depends on the context.

I tried googling but had trouble with those.

Well, Tubewells seems pretty literal. It is a tube that is a well. Half way down this page is a pic of a few basic types: http://users.physics.harvard.edu/~wilson/arsenic/conferences/Feroze_Ahmed/Sec_2.htm

The trick is to add the words "definition" and "of" before it. =) http://lmgtfy.com/?q=definition+of+Rationale

If you look at it, the rational is the reasons behind.  So if I were to say, "My rational in doing this is..."  I would be explaining why I did something.
