Use of organic enrichment as additives in coconut coir dust on development of tomato in soilless culture

Amendment of empty fruit bunch (EFB) and vermicompost (VC) in coconut coir dust (CD) has been promoted as a potential alternate media in soilless culture. However, in commercial overview, several problems can be seen in the use of amendment with coconut coir dust as a growth media. The aim of this study was to investigate the effect of EFB and VC as organic amendment (10%–40%; v/v) on the growth and yield of tomato plant in CD media. Six treatments were used with five replications. A 100% CD with nutrient solution (electrical conductivity [EC] = 2.5 mS · cm−1) was used as control treatment. The other treatments were 30 EFB, 10, 20, 30, and 40% VC, which were equivalent to half strength of the nutrients supplied in control. The results showed that plants grown in CD with 20% VC had higher vegetative growth and yield.
