Effect of Bioculture Fertilizer and Biological Fertilizer on the Growth and Yield f Tomato Plants (Solanum Lycopersicum L.), Servo F1 Variety

Abstract— The aim of the research was to determine the effect of bioculture and biofertilizers and their interactions on the growth and yield of Servo F1 tomato varieties and to obtain appropriate concentrations of biocultural and biofertilizers for tomato plants.

The research was conducted from May to July 2022, at the UPTB Agricultural Training Center (BAPELTAN) Jl. Thoyib Hadiwijaya No.36, South Sempaja urban village, North Samarinda sub-District, Samarinda, East Kalimantan Province.

The study used a 4x4 factorial experiment in a completely randomized design with four (4) repetitions. The first factor was the concentration of bioculture fertilizer (B), consisting of 4 levels, namely: no bioculture fertilizer application or control (b₀), 10 ml L^-1 water (b₁), 20 ml L^-1 water (b₂), and 30 ml L^-1 water (b₃). The second factor is biofertilizers (H) consisting of 4 levels, namely: no biofertilizers application of control (h₀), 5 ml L^-1 water (h₁), 10 ml L^-1 water (h₂), and 15 ml L^-1 water (h₃).

The data collected were plant height at 20, 40 and 60 days after planting, plant age at flowering, number of fruits per plant and fruit weight per plant. Data analysis was carried out using analysis of variance and continued with the leasr significant difference test at the 5% level.

The results showed that: (1) application of bioculture fertilizers had a very significant effect on the plant height at 20, 40 and 60 days after planting, and fruit weight per plant. The highest fruit weight per plant was produced in the treatment 30 ml L^-1 water (b₃) namely 156,25 g crop^-1, and the lowest was produced in the treatment without bioculture fertilizers (b₀), namely 128,75 g crop^-1; (2) application of biofertilizers had a significant to very significant effect on the plant height at aged 40 and 60 days after planting, number of fruits per plant and fruit weight per plant. The highest fruit weight per plant was produced in the treatment 15 ml L^-1 water (h₃) namely 156,25 g crop^-1, and the lowest was one was produced in the without biofertilizers (h₀), namely 128,75 g crop^-1; and (3) there is an interaction between the treatment of bioculture fertilizers and biofertilizers on the plant height at the age of 20, 40 and 60 days after planting.
