Abstract

Tea shoot yields in Indonesia have fluctuated over the past five years. The high population of seed-origin tea plants with low productivity is a contributing factor. Replacing them with clonal plants with higher productivity is recommended to increase the productivity of seed tea plants. The obstacle faced is that replacing these plants requires high costs. Therefore, other efforts are made by fertilising to maintain the availability of nutrients and soil conditions to support the growth of tea plants. This experiment aims to determine the effect of applying a combination of liquid biofertilizers and inorganic fertilisers on the quality and quantity of tea plant yields. The experiment was conducted from June to December 2024 using a Randomised Block Design with 10 treatments and 3 replications. The treatments consisted of a combination of microbial-based biofertilizers at doses of 20 L/ha, 30 L/ha, and 40 L/ha, and inorganic fertilisers at doses of 50%, 75% and 100% of the recommended dose. The results showed that the combination of microbial-based biofertilizer and inorganic fertiliser significantly affected shoot wet weight, percentage of pecco weight, ratio of pecco to dormant shoots, and shoot yield. The treatment of 40 L/ha + 100% of the recommended dose of inorganicfertiliser gave the best results regarding the ratio of pecco to dormant shoots and percentage of pecco weight. The treatment of 40 L/ha + 75% recommended dosage of inorganic fertilizer gave the best results for shoot wet weight and shoot yield.
