Abstract

Red chili (Capsicum annum L.) is a spice commodity with high economic value that is increasingly being developed because it not only functions as a cooking spice but also as a functional food due to its bioactive compound content. Improving the growth and production of red chili can be done through the application of liquid biofertilizer on superior and local varieties of red chili from Lubuk Cuik which is a center of red chili production in North Sumatra. This study aims to identify the role of liquid biofertilizer in increasing the growth, and production of red chili from Lubuk Cuik and superior varieties is very important to do. The study was conducted in the field of the Agricultural Training and Mechanization Unit of the Horticultural Food Security Service of North Sumatra Province, using a Factorial Randomized Block Design with two factors and 3 replications. The first factor is the concentration of liquid biofertilizer (0, 10, 20 and 30 ml/L of water), and the second factor is the variety (White Local, Green Local, Dji-tu F1 superior variety, and Laju F1 superior variety). The data was analyzed using analysis of variance, if there was a significant difference then it was continued with Duncan's Multiple Range test at alpha level = 5%. The results showed that 30 ml/L of liquid biofertilizer resulted in improved plant height, branch number, and stem diameter, as well as accelerated flowering and fruit ripening. The Dji-tu F1 variety had higher yields than other varieties, while the Laju F1 variety tended to flower and ripen earlier. Overall, the use of 30 ml/L of liquid biofertilizer on superior varieties improved the growth and yield of red chili.
