Efektivitas Konsentrasi AB Mix dan Zat Pengatur Tumbuh Terhadap Pertumbuhan dan Hasil Seledri (Apium Graveolens L.) Secara Hidroponik

Abstrak

Celery (Apium graveolens L.) is a leafy vegetable plant with high economic value and is widely used as a food ingredient and traditional medicine. Hydroponic celery cultivation is an effective alternative to increase productivity because it can provide optimal nutrients and water. The success of hydroponic cultivation is greatly influenced by the concentration of AB Mix nutrients and the use of plant growth regulators (PGRs). This study aims to determine the effectiveness of various concentrations of AB Mix and PGRs on the growth and yield of hydroponic celery plants and to determine the best treatment combination. The study was conducted using a factorial Completely Randomized Design (CRD) consisting of two factors. The first factor is the concentration of AB Mix which consists of three levels, namely 800 ppm, 1,200 ppm, and 1,600 ppm. The second factor is the concentration of PGRs which consists of three levels, namely 0 mL L⁻¹, 2 mL L⁻¹, and 4 mL L⁻¹. Each treatment combination was repeated three times. The parameters observed included plant height, number of leaf stalks, and plant fresh weight. Data were analyzed using analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) at the 5% level. The results showed that AB Mix concentration significantly affected the number of celery leaf stalks. PGR application also significantly affected the number of leaf stalks and plant fresh weight. The interaction between AB Mix concentration and PGR on celery growth and yield was not significant for all parameters.
