The Effectiveness of Various Natural PGR Combination on Seed Germination, Growth and Yield of Red Chili (Capsicum annuum L.)

Abstract

The demand for red chili peppers (Capsicum annuum) is increasing due to the relatively high needs in market. One way that can be done to support the cultivation of red chili plants is to use Plant Growth Regulator (PGR). However, the access to synthetic PGR is quite limited for farmers in rural area, so an alternative PGR that are easier to find, cheaper and environmentally friendly is needed. This study aims to determine the effect natural PGR’s combination made from shallots, bamboo shoots and coconut water in supporting seed germination, growth and production of red chili. This study used a Randomized Block Design (RBD) with 4 treatments which are the combinations of 50 ml/L shallot filtrate and 50 ml/L bamboo shoot filtrate, 50 ml/L bamboo shoot filtrate and 50 ml/L coconut water, 50 ml/L shallot filtrate and 50 ml/L coconut water, and a combination of the three. The data obtained then analyzed with one-way Anova Test followed by Duncan Test, if there was a significant influence. The results showed that there was a significant effect of natural PGR combination treatment on the growth of red chilli peppers, but there was no significant effect on seed germination and production. The most optimal natural PGR combination for red chili growth was the third treatment, a combination of shallot filtrate at 50 ml/L, bamboo shoot filtrate at 50 ml/L, and coconut water at 50 ml/L.
