Garlic is one of the horticultural commodities included in the Amaryllidaceae family which has health benefits such as lowering cholesterol levels, lowering high blood pressure, and overcoming stomach ulcers. Domestic garlic production in 2023 was only 30,194 tonnes, while the domestic demand for garlic reached 554,000 tonnes. This is due to the low production of garlic due to the limited land used for garlic cultivation. Based on this, it is necessary to increase the growth and production of garlic, one of which is by using growth regulators. The aim of this study was to examine the effect of bamboo shoot extract, coconut water, GA3, and cytokinin on the growth and yield of garlic. The research was conducted from June-August 2024, in farmers' land located in Dukuh Pancot, Kalisoro Village, Tawangmangu District, Karanganyar Regency, Central Java. The method used was a Randomized Complete Block Design (RCBD) with treatment factors, namely no treatment, bamboo shoot extract (25 and 50%), coconut water (25 and 50%), GA3 (60 and 120 ppm), and cytokinin (60 and 120 ppm) and three replications. Observational variables were environment (air temperature, air humidity, light intensity, and rainfall) and initial soil analysis which were analysed descriptively as well as growth and yield (plant height, number of leaves, stalk fresh weight, stalk dry weight, tuber diameter, number of cloves per tuber, tuber fresh weight, and dry tuber productivity) which were tested using Analysis of Variant (ANOVA) with a significance level of 95%. The results showed that the 50% coconut water treatment was the most effective in improving garlic growth in terms of fresh weight of the plant and the most effective in improving garlic yield in terms of bulb diameter (7.68% compared to no treatment) and fresh weight of the bulb (31.52% compared to no treatment) and compared to the bamboo shoot extract treatment, GA3, and cytokinin treatments, but it did not affect the dry bulb weight per clump and dry bulb weight productivity.
