The "poetic subject" of a poem is whatever the poem is about. For instance, Wordsworth's sonnet "The World Is Too Much with Us," the poet laments that we are consumed by the stress of materialism and getting by in the world. He wishes that we could just lose ourselves in nature and not worry about all the rest. So you could say that the subject of the poem is nature vs. materialism or nature vs. industrialization.
I suspect that you might be using "poetic subject" in the same sense as "theme." In that case, for whichever poems you are writing about, you should read the eNotes study guide discussion of theme for each of those poems.

TASTING THE LANDSCAPE
the botom of the pan was a palette-
haldi,heaped like powder paints.
melted ghee made lakes,golden rivers
the keema(minced meat)frying my mother waited
for the fat to bubble to thr surface.
frnds bought silver-leaf.
i dropped it on khir-
special rice pudding for parties.
i tasted the landscape,customs
of my fathers country
its fever biting a chili-
