Assuming that you intend for the Sqrt to encompass the entire argument,
$Version
"7.0 for Mac OS X x86 (64-bit) (February 19, 2009)"
Plot3D[Sqrt[t*(1 - z)*(t - z)],
{z, 0, 2}, {t, 0, 2}]
Assuming[#, Integrate[Sqrt[t*(1 - z)*(t - z)],
{t, 0, z}]] & /@
{{0 < z}, {0 < z < 1}, {1 < z}}
{-((z^2*(2*I*Sqrt[1/(1 - z)]*
Sqrt[-1 + z]*
Log[2*I*Sqrt[z]] +
Log[4*z]))/
(8*Sqrt[1/(1 - z)])),
(1/8)*I*Pi* Sqrt[1 - z]*z^2,
(1/8)*Pi*Sqrt[-1 + z]*z^2}

=============
Could any body help me to solve the following integral in
mathematica?
Integrate[sqrt[t * (1-z)*(t-z),{t,0,z}]; t and z are reals; z>0
I did make a mistake posting the wrong equation yesterday, I apologize
for that.
Any help would be appreciate,
