Arukh ha-Shulchan/Even Haezer/1
“ Section 4 Some scholars write that even though women are not obligated in the commandment of 'be fruitful and multiply', they are still obligated in the commandment of 'filling the world'. However, this good practice (of women getting married) is not the law, because the obligation of 'be fruitful and multiply' is given for the reason of "filling (the world) ", as I have written. Because women are not commanded in 'be fruitful and multiply', they are not obligated in the commandment of "filling the world". ”
