Abstract

This study aims to determine the effect of goat manure and organic NPK fertilizer on the growth and production of red chili peppers (Capsicum annuum L.) in red-yellow podzolic soil (PMK). This study was conducted at the Experimental Garden of the Faculty of Agriculture, University of Riau. The study was conducted over a period of 4 months, from December 2023 to March 2024. This study used a completely randomized factorial design consisting of 2 factors. The first factor was goat manure fertilizer, consisting of 4 treatment levels with doses of 0, 375, 750, and 1,125 g/polybag. The second factor was organic NPK organic fertilizer, consisting of 4 treatment levels with doses of 0, 7.5, 15, and 22.5 g/polybag. The parameters observed were plant height, flowering age, harvest age, fruit weight per plant, fruit weight per fruit, and number of remaining fruits. The data were statistically analyzed and followed by a significant difference test at the 5% level. The results showed that the interaction between goat manure and organic NPK fertilizer significantly affected the parameters of plant height, number of fruits per plant, fruit weight per plant, fruit weight per fruit, and number of remaining fruits on red chili plants. The main effect of goat manure fertilizer was significant on all observed parameters, with the best treatment at a dose of 1,125 g/plant. The main effect of organic NPK fertilizer was significant on all observed parameters, with the best treatment at a dose of 22.5 g/plant. Keywords: Red Chili Pepper, Organic NPK
