The noun ᴱQ. nesta “(act of) feeding” appeared in the Qenya Lexicon of the 1910s derived from the early root ᴱ√NESE (QL/66).
Neo-Quenya: For purposes of Neo-Quenya, I’d instead use the gerund ᴺQ. nestië of the verb ᴺQ. nesta- “(give to) feed”.
There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
The verb ᴱQ. nesta- “feed” appeared in the Qenya Lexicon of the 1910s as a derivative of the early root ᴱ√NESE “give to feed; feed, pasture; graze” (QL/66). It has past forms nēse and nesse, indicating a close relationship to the verb ᴱQ. nese- “graze, pasture, give to feed, feed” from the same root, which likely would have had the same or similar past-tense forms.
Neo-Quenya: For purposes of Neo-Quenya, I would combine both these early verbs into ᴺQ. nesta- “to graze, pasture, give to feed, feed”, derived from the Neo-Root ᴺ√NES.
