Abstract

The productivity of narrow land urban can be increased by planting tower growth vertically. The research purpose is to determine the response to growth and yield, as well as the chlorophyll content of lettuce (Lactuca sativa L.) by planting media composition and types of foliar fertilizer. The research was carried out from January to March 2023 in Wates Village, Magersari District, Mojokerto City. This factorial research consists of two factors and was prepared using a Completely Randomized Design (CRD). The first factor is the composition of the planting medium with a volume ratio of soil: compost: goat manure which consists of four levels, namely: M1 = 1:1:1; M2 = 2:1:1; M3 = 1:2:1; and M4 = 1:1:2. The second factor is the type of foliar fertilizer which consists of 3 levels, namely: D1 = NASA; D2 = Gandasil D; and D3 = Nutriplan. The research data were analyzed using analysis of variance (ANOVA). If the treatment has a real effect, then continue the BNJ test at the 5% level. The results of the research showed that the combination treatment of soil: compost: goat manure (1:1:1) and NASA leaf fertilizer increased the total fresh weight and chlorophyll content of lettuce plants and was significantly different from other treatment combinations. The single treatment of soil planting media composition: compost: goat manure 1:1:1 increased plant length, number of leaves, root length, and fresh root weight of lettuce plants the highest and was significantly different from other planting media composition treatments. Gandasil D foliar fertilizer increases plant length, while NASA foliar fertilizer.
