Abstract

Chili is one of the vegetable commodities that is often consumed by people in Indonesia. The demands of chili will increase along with population and industrial development in Indonesia. The rising demand for chili will increase the use of chemical fertilizers, especially Urea and NPK. Efforts to reduce the use of excess chemical fertilizers are to use biofertilizers and biochar. Biofertilizers function to provide nutrients to replace chemical fertilizers while biochar is a soil ameliorant material that can bind nutrients and water in the soil. The application of biological fertilizers and biochar is expected to improve the chemical, biological and physical properties of the soil so as to provide media and nutrients for plant growth. In addition, the purpose of this study was to obtain the best combination dose of biochar and biofertilizer on the growth and yield of red chili. This study used a factorial randomized group design (RAK). The first factor is the dose of biofertilizer (Y) consisting of 3 levels, namely 6 l/ha, 8 l/ha and 10 l/ha. The second factor is the dose of biochar (B) consisting of 4 levels, namely 6 tons/ha, 8 tons/ha, 10 tons/ha and 12 tons/ha. The results showed that the combination of biofertilizer doses and biochar treatments interacted with plant height at 28 and 35 HST (Days After Planting), number of leaves at 35 HST and fruit weight throughout the harvest period. The best combination was found at a dose of 6 l/ha biofertilizer and a dose of 8 tons/ha biochar. Keywords: growth and yields, chili, biochar, biofertilizers

Abstract

Purple eggplant (Solanum melongena L.) is one of the horticultural commodities that is quite much in demand by the people of Indonesia. The need and demand for purple eggplant every year continues to increase along with the increase in population, but purple eggplant production in some areas is still quite low due to one of them is limited land due to land conversion and less fertile land. This research was conducted from December 2024 to March 2025 in Bulurejo Village, Rengel District, Tuban Regency, East Java. This research was designed using a completely randomised design (RAL) which was arranged factorially and consisted of two treatment factors. Factor The first factor is the provision of husk charcoal (A) which consists of four levels, namely A0: 0 g/plant (control), A1 100 g/plant (control), A2: 100 g/plant (control), A3: 150 g/plant (control): 150 g/plant, A2: 150 g/plant, A3: 200 g/plant. The second factor is the application of several concentrations of Gandasil B (G) consisting of four levels, namely: G0: 0 g/L (control), G1: 2 g/L, G2: 3 g/L, G3: 4 g/L. The results showed an interaction between the application of husk charcoal 200g/plant and the concentration of Gandasil B 3g/l (A3G2) which produced the highest number of total flowers per plant, total fruit per plant, and total fruit weight per plant but not significantly different from the treatment of a combination of the application of husk charcoal 150 g/plant (A2G2) and the concentration of Gandasil B 3 g/l and a combination of the aplication of husk charcoal 200 g/plant and the concentration of Gandasil B 4 g/l (A3G3).
