Merr. fruit contains 78-87% citric acid, which is found in organic acids other than malic acid and oxalic acid, and the content of Citrullus colocynthys (L.) Schrad. fruit. has a relatively high level of acidity compared to Ananas comosus (L.) Merr. fruit so that it can limit the level of acidity in the effect of citric acid Ananas comosus (L.) Merr. fruit and also good for the growth and yield of Vigna unguiculata ssp. Sesquipedalis.Methodology:This Study used a Factorial Randomized Group Design (RGD).
