Effect of fermented plant juice (FPJ) and fermented fruit juice (FFJ) on growth performance of Kaempferia Parvillora cultivated using bench fertigation system

Growth of Kaempferia parviflora or black ginger were studied in this research. Black ginger plant is usually grown in shifting cultivation which is a traditional cultivation practice that leads to land use issues as well as soil -borne diseases. So in this study, black ginger cultivation using bench fertigation system and soilless crop media such as coir pith, raw and burnt paddy husk were used to replace the traditional cultivation method. Then to support the growth of this black ginger plant, the application of AB fertilizer and supplementation of FPJ and FFJ crops was studied to see its effectiveness on plant height, number of leaves, longest leaf, widest leaf and plant weight. From the study it can be seen that the effect of AB fertilizer application as a control shows less development on crop growth. While application of AB fertilizer with FPJ supplementation in the first 4 weeks had a good effect on the number of leaves with mean readings from 1.40 cm to 2.60 cm. further the use of AB fertilizer with FFJ also showed a good effect on the development of leaf width where the mean reading of the widest leaf in week 6 to week 7 increased from 8.71 cm to 8.90 cm. based on the observations that have been made, the use of AB and FFJ fertilizers showed favourable crop development after 8 weeks of planting. Results for all crop growth parameters were significant except for insignificant plant weight. The results were recorded using Microsoft Excel software, SPSS and analysed using ANOVA.
