You don't say how large an area you are trying to bring up, but I have 
had fair luck in fields that are 50'+ wide and 300'+ length with two 
types:
1) A string of micro sprinklers on moveable stakes can water a strip 
10-15' wide and about two hundred feet long (about 30 sprinklers) when 
fed from a single 16mm tube attached to a hose bib.  The sprinklers cost 
about $1 each while the 16mm tube is about $.05 per foot.  I normally run 
such a configuration 1/2 to 1 day per set.
2) A small "Water Reel" will provide quite uniform coverage, but cost 
about $2000 and requires around 20gpm at 40psi or more.  This will 
cover a strip nearly 200' in length and 60-80' wide with a single 3/4" 
impact sprinkler head.

Much of my irrigation is from T-Tape buried in 5' c-c beds and I do 
have a very difficult time getting anything germinated in dry weather 
with the T-Tape alone.

I recommend Irrigation Mart in Louisana as a source:
