Abstract
Purple eggplant (Solanum melongena L.) is a high-value horticultural crop with increasing market demand due to its rich nutritional content. However, current production levels have not kept pace with this rising demand. This study aimed to evaluate the optimal combination of Dekamon plant growth regulator (PGR) concentrations and NPK Phonska Plus fertilizer doses on the growth and yield of purple eggplant. A factorial experiment was conducted using a Completely Randomized Design (CRD) with two factors: PGR concentrations (0, 2, and 4 ml/l) and NPK fertilizer doses (800, 1,000, and 1,200 kg/ha). The results showed a significant interaction between PGR and fertilizer treatments. The best combination was 2 ml/l Dekamon with 1,000 kg/ha NPK (D1N2), which significantly improved plant height, number of leaves, number and weight of fruits per plant, and yield per harvest period. Meanwhile, the combination of 4 ml/l Dekamon and 1,200 kg/ha NPK (D2N3) was most effective in increasing total fruit weight and fruit diameter. PGR treatment alone significantly affected all parameters except fruitset percentage, while NPK fertilizer treatment significantly affected all variables except days to flowering and fruit length.
