Pepper cultivation is widely accepted by consumers and is responsible for supporting the establishment of family farming by providing employment for manpower. This study aimed to investigate the effects of nitrogen fertilization and hydroretentor gel application on the development and productivity of Capsicum sp. Each experiment applied a 2 x 5 factorial randomized block design, with and without the application of hydroretentor gel (factor A) with five N (factor B) doses (0; 50; 100; 150 and 200 kg ha-1), and four replications. Analysis was made of the foliar nitrogen content, chlorophyll content, plant height, stem diameter, fruit length, fruit diameter, fruit number and weight, and productivity. The application of gel hidroretentor only influenced the culture of chilli pepper in the development and productivity. The nitrogen doses increased the productivity of yellow chilli and favored only the development of chilli pepper
