Effect of NPK fertilizer (16-16-16) concentration on the production and quality of cayenne pepper seeds (Capsicum frutescens L.) Bonita and Loblita varieties

Abstract

One way to increase the production and quality of cayenne pepper seeds is by proper fertilization. The purpose of this study was to obtain the best concentration of NPK (16-16-16) fertilizer for the production and quality seeds of Bonita and Loblita varieties. This study used a nested design with a basic design of randomized group design consisting of 4 levels of NPK (16-16-16) fertilizer concentrations (0 g/l (control), 5 g/l, 10 g/l, and 20 g/l) and 2 varieties of cayenne pepper (Bonita and Loblita) using 3 replications. The concentration of 5 g/l NPK fertilizer (16-16-16) on the Bonita variety gave the best results on germination (85,33%), seed growth speed (24,73%/ethmal), and seed growth uniformity (84,33%). While in the Loblita variety, the concentration of NPK fertilizer (16-16-16) 10 g/l gives the best results on germination (83%), seed growth speed (11,31%/ethmal), and seed growth uniformity (64,33%).
