Morphology
The phrase combines 'nutrient' (providing nourishment) with 'agar' (a gelatinous gelling substance), so the meaning — agar that contains nutrients used as a culture medium — follows directly from the constituents. Although it is a technical laboratory term, the noun+noun composition is transparent and predictable, so a learner who knows both words can infer the MWE's meaning.
Etymology
Nutrient agar gets its name from its two parts: nutrient (food) and agar (a jelly from seaweed). Scientists pour this jelly into flat plates so tiny organisms can 'grow' on it, so the name shows it is used for 'growing' microbes.
