Background and Objective: Verticulture is an effort to narrow land use for marigolds (Tagetes erecta L.) optimally. To obtain a good result, a plant needs suitable environmental conditions. Included in these factors are planting media and nutrient requirements. The purpose of this research was to determine the effect of planting media composition and fertilization techniques on the growth and flowering of marigolds in the verticulture system. Materials and Methods: The research was conducted on the 6th floor of the rooftop at Malang at 450 m.a.s.l from April-June, 2019. The materials used are yellow marigold seedlings planted in 5 dim vertical pipes, a mixture of media (soil, husk, cocopeat) and vermicompost as planting media, also NPK (6:13:25) 3 g/plant. We used a randomized block design with 6 treatments of Vermicompost (V) and Non-Parametric Kinetics (NPK) method application (Band Placement (BP) and Fertigation (F)), such as P 1 = 0% V+NPK BP, P 2 = 50% V+NPK BP, P 3 = 100% V+NPK BP, P 4 = 0% V+NPK F, P 5 = 50% V+NPK F and P 6 = 100% V+NPK F. It performed 4 replications and was tested using 5% LSD. Results: The results showed that 50% vermicompost and band placement can increase the vegetative and generative growth of marigolds. Furthermore, it is known that plants grown with 50% vermicompost and fertilization techniques of the band placement flower faster than plants grown with other treatments. The number of flowers is 60% higher than 0% vermicompost with the NPK fertigation technique. Conclusion: Therefore, to obtain the optimal result for the growth and flowering of marigolds, it is suggested to apply 50% vermicompost media and use the NPK band placement technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
