Pengaruh Beberapa Dosis Pupuk Kalium Terhadap Pertumbuhan Dan Produksi Tanaman Tomat (Solanum Lycopersicum Mill.)

ABSTRACT
Tomato (Solanum lycopersicum Mill.) is a high-value horticultural commodity that requires specific cultivation management, particularly concerning nutrient availability. Potassium (K) is one of the essential macronutrients influencing tomato growth and productivity. Inceptisol soils, which are widely distributed in Indonesia, are characterized by low potassium content, necessitating fertilization to enhance soil fertility and crop yield. This study aimed to evaluate the effect of different potassium fertilizer doses on the growth and yield of tomato plants and to determine the optimal dosage for maximizing production. The experiment employed a Completely Randomized Design (CRD) with one factor, namely potassium fertilizer dosage (0 kg/ha, 75 kg/ha, 125 kg/ha, 175 kg/ha, and 225 kg/ha), each replicated four times, resulting in 20 experimental units. Each unit consisted of 10 tomato plants, with 3 randomly selected plants per unit observed as samples, totaling 60 observed plants. Data were analyzed using Analysis of Variance (ANOVA), followed by Honest Significant Difference (HSD) test at a 5% significance level, and correlation analysis was conducted to assess the relationships between parameters. The observed parameters included plant height, stem diameter, number of branches, flowering age, harvesting age, number of fruits per plant, fruit diameter, and fruit weight per plant. Results showed that potassium fertilization significantly affected all growth and yield parameters. The application of 125 kg/ha KCl resulted in the best performance, enhancing both growth and yield of the Servo F1 tomato variety. This dosage is recommended for tomato cultivation on Inceptisol soils to increase harvest productivity.
