Variations in macronutrient fertilization and spacing are two important components in increasing shallot yield. This study aims to determine the effect of fertilization and plant spacing on shallot yield. A split-plot design with three replications was applied. The main plots were plant spacing (D1: 20 x 20 cm, D2: 20 x 15 cm, D3: 20 x 10 cm); subplots were fertilization of TSP, NPK, KNO3, Urea, and ZA with four doses: F1 by 188, 600, 0, 180, 400 kg ha-1; F2 by 75, 225, 80, 57, 300 kg ha-1; F3 by 100, 300, 107, 76, 400 kg ha-1; and F4 by 125, 375, 135, 95, 500 kg ha-1, respectively. Data was analyzed using the Anova (Analysis of Varians) and Duncan tests. The number of leaves was positively correlated with wet bulb weight per clump (R2 = 86.36%), and dry bulb weight per clump (R2 = 72.40%). The optimum N, P, and K dosages to achieve the optimum relative yield were 126.85; 178.06; 95.25 kg ha-1. The D3F3 interaction (plant spacing of 20x10 cm with TSP, NPK, KNO3, Urea, and ZA fertilization by 100, 300, 107, 76, and 400 kg ha-1, respectively) enhanced the dry bulbs weight per plot by 84.50%. |
