First measurements of mesons production properties and their spin alignment in 
charged current (CC) and neutral current (NC) interactions are presented. The analysis of the full data sample of the NOMAD experiment is performed in different kinematic regions. For 
and 
mesons produced in CC interactions and decaying into 
we have found the following yields per event: 
and 
respectively, while for the and mesons produced in 
interactions the corresponding yields per event are: 
and 
. The results obtained for the 
parameter, 
and 
for 
and 
produced in CC interactions, are compared to theoretical predictions tuned on LEP measurements in 
annihilation at the 
pole. For mesons produced in interactions the measured parameter is 
.
