Ningishzida's titles connect him to plants and agriculture.{{sfn|Wiggermann|1998|p=369}} He was frequently mentioned in connection with grass, which he was believed to provide for domestic animals.{{sfn|Wiggermann|1998|pp=369-370}} The death of vegetation was associated with his annual travel to the underworld.{{sfn|Wiggermann|1998|p=370}} The "tree" in his name might be [[Vitis|vine]] according to some Assyriologists, including [[Wilfred G. Lambert]], and an association between him and alcoholic beverages (specifically [[wine]]) is well attested, for example one text mentions him alongside the beer goddess [[Ninkasi]], while one of his titles was "lord of the innkeepers."{{sfn|Wiggermann|1998|p=370}}
Like his father Ninazu, he was also associated with snakes, including the mythical [[mushussu]], [[ushumgal]] and [[bashmu]] and in one case [[Nirah]].{{sfn|Wiggermann|1998|p=370}} He was also an underworld god, and in this role was known as the "chair bearer (or chamberlain) of the underworld."{{sfn|Wiggermann|1998|p=371}} Frans Wiggermann on the basis of these similarities considers him and his father to be members of the group of "[[Tigris|Transtigridian]] snake gods," who according to him shared a connection with the underworld, justice, vegetation and snakes.{{sfn|Wiggermann|1997|pp=47-48}} A further similarity between Ningishzida and his father was his occasional role as a warrior god, associated with victory (and as a result with the goddess [[Irnina]], the personification of it).{{sfn|Wiggermann|1998|p=371}} However, not all of their functions overlapped, as unlike Ninazu, Ningishzida never appears in the role of a divine healer.{{sfn|Wiggermann|1998|p=369}}
