<![CDATA[This study investigated the effects of Lemek Sari organic fertilizer and NPK Tawon inorganic fertilizer on the growth and yield of chili (Capsicum annuum L.). A randomized block design with a factorial arrangement was employed, incorporating five Lemek Sari doses (0, 10, 20, 30, 40 t ha?¹) and four NPK Tawon doses (0, 200, 400, 600 kg ha?¹). NPK Tawon fertilizer exerted highly significant effects (P < 0.01) on all measured growth and yield parameters. The optimum dose of 600 kg ha?¹ produced the highest fruit weight (202.37 g), representing a 2073.68% increase over the unfertilized control. Lemek Sari organic fertilizer applied independently had a significant effect solely on stem diameter (P < 0.05), whereas the 40 t ha?¹ dose elevated fruit weight by 90.07% relative to the control. A highly significant synergistic interaction (P < 0.01) was observed for the number of harvested fruits, with the combination of 40 t ha?¹ Lemek Sari and 600 kg ha?¹ NPK Tawon yielding the highest fruit number (34.67 fruits per plant), compared to zero fruits in the unfertilized control. Correlation analysis revealed near-perfect positive relationships (r > 0.90) among vegetative and generative parameters under NPK Tawon treatment, confirming that macronutrient supply acted as the primary limiting factor for yield formation. These findings demonstrate that soil improvement by high-dose Lemek Sari organic fertilizer maximizes the efficiency of NPK Tawon, providing a scientifically grounded strategy for sustainable intensification of chili production.]]>
