The Effect of Plant Growth Promoting Fungi Mycorrhiza and Trichoderma on The Productivity of Edamame Soybean Plants (Glycine Max (L.) Merrill)

Nurfadila — 2025-10-19

Sustainable edamame cultivation using Plant Growth Promoting Fungi (PGPF) Mycorrhiza sp and Trichoderma sp is still not widely applied by Indonesian farmers. The purpose of this research was to test the effect of plant growth promoting fungi Mycorrhiza sp and Trichoderma sp on the productivity of edamame soybean plants. This research was conducted from June to September 2024 at Jember City. The research design used was a Completely Randomized Design (CRD) with 4 levels with 5 replications until there were 20 experimental units with treatment levels, P0: 0 gr/plant (Negative control), P1: 15 gr/plant Mycorrhiza sp, P2: 15 gr/ plant Trichoderma sp, P3: 15 gr/plant both PGPF (7.5 gr/ plant Mycorrhiza sp + 7.5 gr/ plant Trichoderma sp). Observation variables include plant height, trifoliate, productive branches, flowering age, root infection. The research results show that the observation variables of plant height and productive branches have different results that are not significant while trifoliate had an effect of treatment on the observation of variables of week 1 and week 2 and the observation variables of flowering age it shows that the first flowers appeared at the age of 42 dap and root infection had an effect which is indicated by the presence of hyphae on the roots of soybean plants. The Treatment of PGPF Mycorrhiza sp and Trichoderma sp had an effect on the observation of flowering age and root infection, while the single treatment Mycorrhiza sp had an effect on the observation of the number of trifoliate leaves.

Climate Analysis Based on Remote Sensing

Climate was an important factor that greatly influenced human life and the environment. Remote sensing facilitated the monitoring, recording, and interpretation of climate data, which could be used for geographic reference–based decision-making. This study aimed to analyze climate components using satellite imagery data. The research was conducted in Mojokerto Regency from January to April 2024. The analyzed climate parameters included LST from Landsat 8 SR, RH and THI from ERA 5, rainfall from CHIRPS, and evapotranspiration from MODIS. All data were processed and analyzed on the cloud computing platform GEE. The analysis of 2023 satellite imagery showed that Mojokerto Regency’s climate, in terms of LST, was dominated by the medium class (57.4%), RH was classified as slightly dry (47.4%), THI indicated uncomfortable (too hot) conditions in 32.4% of the area, rainfall was generally low (72%), and evapotranspiration was low in 65.9% of the total area. The results of this study could be used to develop strategies for increasing vegetation cover, implementing environmentally friendly land management, and adopting climate adaptation measures to reduce the risk of environmental degradation.

The effect of Auxin Concentratioin and Planting Media Composition on The Growth and Yield of Straw Mushrooms (Volvariella volvaceae)

This research investigates the effect of auxin concentration and planting media composition on the growth and yield of paddy straw mushrooms (Volvariella volvacea). Using a completely randomized design (CRD), this study tested various treatment combinations of planting media composition consisting of 100% straw (M1), 75% straw + 25% tofu dregs (M2), and 50% straw + 50% tofu dregs (M3), as well as the addition of several auxin concentrations consisting of control or without auxin (K0), synthetic auxin 3 ml/L (K1), auxin 6 ml/L (K2), and auxin 9 ml/L (K3). The 100% straw planting medium (M1) resulted in the highest number of fruiting bodies, while the treatment combination of 75% straw and 25% tofu dregs with the addition of 6 ml/L auxin concentration (M2K2) is recommended to provide the best results for fruiting body diameter. In addition, the treatment combination of 75% straw and 25% tofu dregs with the addition of 9 ml/L auxin concentration (M2K3) produced the highest fruiting body weight. This research recommends the use of the right combination of media and auxin concentration for optimal paddy straw mushroom cultivation. The results of this study are expected to provide guidance for farmers in increasing the productivity of paddy straw mushrooms in Indonesia, especially in East Java, by utilizing organic waste as a nutrient-rich planting medium.
