Abstract

Biofertilizer application can potentially reduce chemical residues in soil from synthetic fertilizers. This study investigates the effects of varying doses and application frequencies of biofertilizers on the growth, productivity, and Relative Agronomic Effectiveness (RAE) of Glycine max L. A Completely Randomized Design was employed, with 9 treatment combinations and 2 control groups (positive and negative), each replicated three times. The biofertilizer doses tested were 5, 10, and 15 ml per plant (B5, B10, B15), and application frequencies included 1 week after planting (WAP) (F1), at 1 and 4 WAP (F2), and at 1, 4, and 8 WAP (F3). The negative control received no biofertilizer, while the positive control received NPK (5 g/plant). Plant growth was assessed by measuring height and leaf number, and productivity was evaluated based on the number of pods, pod weight, dry seed weight, and weight per 100 seeds. Data were analyzed using one-way ANOVA. The results indicated that the treatment with 10 ml of biofertilizer applied twice (B10F2) significantly improved the growth and productivity of Glycine max L., achieving an RAE value of 169.70%.

Abstract

The increasing demand for tomatoes has prompted farmers to use chemical fertilizers, which can lead to soil degradation and reduced fertility. This study aims to determine the appropriate dose and frequency of biofertilizer application to enhance the growth and productivity of tomato plants (Solanum lycopersicum L.). The experiment was designed using a Completely Randomized Design (CRD) with 11 treatments, including both negative and positive controls. Three variations in biofertilizer doses were tested (5, 10, and 15 ml/plant), along with three different frequencies of application: once at one week after planting (1 WAP), twice (at 1 and 4 WAP), and three times (at 1, 4, and 8 WAP). Measured parameters included soil fertility (microbial population and functional microbial quality), plant growth (plant height, leaf count, stem diameter), and plant productivity (flower count). Quality of functional microbes were analyzed descriptively. Data of microbial population, plant growth and productivity were analyzed using Kruskal-Wallis and Mann-Whitney tests with a 5% significance level. The results showed significant differences in soil microbial populations and plant height between treatments, although no significant differences were observed in stem diameter, leaf number, or flower number. The treatment with 15 ml/plant applied three times (B15F3) exhibited the highest Relative Agronomic Efficiency (RAE) compared to other biofertilizer treatments (74.63%), but it was still lower than the control (chemical fertilizer). Therefore, higher doses and/or frequencies may be needed to further evaluate the effectiveness of the biofertilizer under test.
