Growth and yield responses of two chili varieties on liquid bio-organic fertilizer

Abstract

One of the horticultural commodities that often causes price fluctuations is chili. The main problem is plant productivity which is low and unstable from one growing season to another, as a result of the application of cultivation technology that is not optimal, especially the use of types and doses of fertilizers. This research was carried out with the main objective of increasing the productivity of two varieties of chili plants by using liquid bio-organic fertilizers. The research was conducted in April-November 2022, in Sidera Village, Sigi-Biromaru District, Sigi Regency. In this study a split plot design was used. The main plot was chili varieties, consisting of: (V1) Bara and (V2) Ozil. The sub plot was the concentration of liquid bio-organic fertilizer (LBO), consisting of: (K0) without LBO, (K1) 2 ml/L water, (K2) 4 ml/L water, (K3) 6 ml/L water, (K4) 8 ml/L water, and (K5) 10 ml/L water. Each treatment was repeated 3 times, so there were 12 experimental units. The results showed: (i) the Ozil variety was more responsive to the application of bio-organic fertilizer, where with a concentration of 8-10 ml/L of water it could produce taller plants, length and larger fruit diameter, compared to the Bara variety with a concentration of bio-organic fertilizer other (ii) The Ozil variety produced taller plants, the number of leaves and the number of branches was higher, the weight per 10 fruits and the weight per fruit were higher, the number of fruits and fruit weight per plant as well as the fruit weight per plot and fruit weight per hectare were higher compared to Bara variety and (iii) The number of branches, weight per 10 pods, weight per pod, number of pods and pod weight per chili plant were obtained higher by the application of herbafarm bio-organic fertilizer 8-10 ml/L of water.
