Abstract

Avocado production in Banten Province fluctuates due to suboptimal nutrient provision. This study used local variety YM avocado seedlings from Lebak Banten which were propagated by grafting. This study aims to determine the effect of liquid organic fertilizer (LOF) concentration from several types of banana stems on the growth of grafted avocado seedlings (Persea americana Mill.). This study used a factorial Randomized Block Design (RBD) consisting of 4 concentration levels: 0, 150, 300, and 450 ml/l and 3 types of banana stems: nangka banana stems, kepok banana stems, muli banana stems. Based on the results of the study, the administration of LOF with a concentration of 300 ml/l gave the best effect on the parameters of seedling height increase, leaf number increase and leaf greenness index. A concentration of 450 ml/l gave the best effect on the parameters of seedling height increase, stem diameter increase, leaf length increase and leaf width increase. While the type of LOF from nangka banana stems gave the best effect on seedling height increase. There is an interaction between the concentration and type of banana stem on the parameters of the comparison of the length and width of avocado plant leaves.

Abstract

This study evaluated the effect of AB Mix concentration on the growth and yield of lettuce (Lactuca sativa L.) varietiesgrown in a Nutrient Film Technique (NFT) hydroponic system. The experiment was conducted from December 2025 to February 2026 at Allisa Farm, Serang, Banten, Indonesia, using a split-plot design with two factors. The main plotconsisted of AB Mix concentrations at 560, 840, and 1000 ppm, while the subplot included three lettuce varieties: Batavia Caipira, Grand Rapids, and Sementel. Data were analyzed by analysis of variance followed by Duncan’s Multiple RangeTest at the 5% level. AB Mix concentration significantly affected several growth and yield parameters. The 1000 ppm treatment produced the highest number of leaves (19.09), leaf greenness (31.60 SPAD units), root length (21.72 cm), and shoot fresh weight (135.67 g), and supported better plant height during the vegetative stage. Variety also had a significanteffect, with Batavia Caipira showing the best performance in number of leaves, leaf greenness, and shoot fresh weight, while Grand Rapids produced the tallest plants. A significant interaction between AB Mix concentration and variety was observed only for leaf area, with the highest value recorded for 1000 ppm AB Mix combined with Batavia Caipira (94.51 cm²).
