Peanut is a food crop with economic value and high fat and protein content. This study aims to determine the effect of phosphate dose on the growth and production of peanuts. This study used a Randomized Block Design, with six treatments and four replications. One treatment consisted of 4 sample plants. The treatments used were as follows: A: 0 grams of TSP per plant (control); B= 0.22 grams of TSP per plant; C= 0.33 grams of TSP per plant; D= 0.44 gram TSP per plant; E= 0.55 grams of TSP per plant; F= 0.66 grams of TSP per plant. The parameters observed in this study were: plant height, number of branches, flowering age, percentage of filled pods, percentage of cipo pods, the weight of 100 seeds, and weight of seeds for each plant. Based on the results of the research that has been carried out, it is concluded that: Phosphate fertilizer affects the growth and production of kidang variety peanuts in the Lebak swamp land, meanwhile, treatment D, i.e. treatment with a phosphate dose of 0.44 grams of TSP per plant, was the best treatment.
