The total momentum and energy conservation relations between particle kinetic energy and wave energy is satisfied for the plasma--maser instability. The Manley--Rowe relation for plasma waves is violated and as a result an efficient energy up-conversion from the low-frequency mode to the high-frequency mode is possible even for a normal unreversed electron population in plasma turbulence. The entropy production rate for plasma turbulence with plasma--maser instability is estimated. The plasma--maser instability always coexists with the quasilinear interaction, thus it has a potential importance to interpret numerous experiments in fusion and astrophysical plasmas.
