Correlation between growth and yield of chili pepper cultivated in histisols

Abstract

Correlations between plant traits is commonly applied in selection to increase effectiveness, and the path analysis can separate them into direct and indirect impacts. This research studied the closeness of the relationships between characters and decomposed it into a direct and indirect relationship between 14 chili genotypes on peat soils. This research was conducted from June 2022 to October 2022 in an agricultural zone station, University of Bengkulu. The soil used is peat soil. A randomized completely block design with three replications of 14 chili genotypes treatment was used to evaluate the study. Each genotype was planted in beds, with 2 genotypes and 20 plants per genotype. Observational data were then analyzed statistically using the correlation formula followed by significant and cross-finding tests using Microsoft Excel. The results showed that the growth characteristics and yield components such as plant height, leaf width, number of primary branches, number of primary branches, number of dichotomies, and number of fruits per plant were positively correlated with chili pepper yields. The determining characteristics for high chili yield on peatland were the number of fruits per plant, the number of dichotomies and the width of the leaves.
