Bio-extract, Coffee ground, Coffee husk, Brassica rapa L.Abstract
The purpose of this research was to study the effects of concentration of coffee ground bio-extract (GE) and coffee husk bio-extract (HE) on the growth of Brassica rapa L. The bio-extracts was produced by fermentation at the ratio of the coffee ground or coffee husk : molasses : water in production of 40 : 10 : 10 kg respectively with 25 g of microbial activator Super LDD 2 for 7 days . The Completely randomized design was used in this experiment. The growth of B. rapa were investigated after treated with the 1:100, 1:300 and
1:500 of GE and HE at 5 PM everyday for 35 consecutive days. The height of B. rapa were measured every 7 days until day 35. The weight of each group was compared by ANOVA and Duncan’s new multiple range test. The results showed that the B. rapa weight and height of GE and HE groups were significantly higher than the control group (p<0.05). The most effective concentration that was 1:500 of GE which could induce the B. rapa weight and height significantly higher than the HE (p<0.05).
