The growth of lettuce depends on the interaction of growth and environmental conditions. Improper crop maintenance may cause low yield of lettuce production. Application of liquid organic fertilizer could be performed as a strategy in crop maintenance. This study aimed to determine the effect and concentration of gamal leaf (Gliricidia sepium (Jacq.) Kunth ex Walp)-based liquid organic fertilizer (LOF) on the vegetative growth of green lettuce plants (Lactuca sativa L.). The research method used a non-factorial Randomised Group Design (RGD), with treatments consisted of P0 (control), P1 (20% gamal leaves-based LOF), P2 (40% gamal leaves-based LOF), and P3 (60% gamal leaves-based LOF). The results showed that Gamal leaves-based liquid organic fertilizer (LOF) that is produced in this research might still contain less macronutrients C, N, P and K that is stated by SNI 7763: 2018 (2-6%), but its application on lettuce as tested plants could still support their growth. Dose of P1 (20%) was the best to support lettuce growth in the form of increased plant height and leaf area index. Dose of P2 (40%) was abble to maintain showed minimum decrease on lettuce total chlorophylls content. Application of dose of P2 (40%) on lettuce growth medium supportes highest uptake of N while the application of dose of P3 (60%) showed highest uptake of P.

Water apple contains high levels of nutrition and vitamin C for the body. This provides great potential for water apple because the demand for production increases every year. The decline in water apple production in North Sumatra is caused by poor seed types. Vegetative propagation by cuttings, cutting methods and administration of auxin PGR are expected to produce quality seeds. This study aims to determine the effect of cutting methods, administration of auxin PGR, and the interaction of cutting methods and auxin PGR on the growth of water apple shoot cuttings (Syzygium aqueum L.) on oasis media. This study used a factorial randomized block design (RAK) with 2 factors and 3 replications. The data obtained were analyzed using the ANOVA test and continued with the Duncan Multiple Range Test (DMRT). The results showed that the best cutting method treatment was flat cutting on the percentage of cutting survival and net assimilation rate. The best administration of auxin PGR was a concentration of 100 ppm on the percentage of cutting survival, early emergence of shoots, number of shoots, relative growth rate and net assimilation rate and a concentration of 200 ppm on root length and number of roots.
