Abstract

The dependence of tobacco farmers on synthetic chemical fertilizers for many years has led to a decline in soil quality and crop yields in the long term, One of the main challenges in tobacco production is to produce quality seeds that can optimally support crop productivity. The research method used a random design of a non-factorial group, each treatment consisted of 3 treatments tested, namely 4 combinations of planting media, namely P0 (Control), P1 (Azotobacter), P3 (Biohumic), P4 (Azotobacter+Biohumic). The results obtained in this study showed that the best results in the combination treatment of azotobacter and biohumic consistently gave the best results on all plant growth observation parameters, this shows a significant synergistic effect between nitrogen fixation by azotobacter and increased nutrient availability by biohumic

Abstract

This study aims to evaluate the best growing medium for the mycelium growth of F1 oyster mushroom (Pleurotus ostreatus) seeds using millet flour as a nutritional supplement. A Completely Randomized Design (CRD) was applied with two factors: the type of growing medium (corn, sawdust, rice husks) and the concentration of millet flour (0%, 25%, 50%, 75%). Observed variables included mycelium growth (cm), mycelium density, and daily growth on the 7th, 14th, and 21st days after inoculation. The results indicated that corn without millet flour (J1P0) produced the best mycelium growth, while adding 25% millet flour to corn (J1P1) and sawdust (J2P1) enhanced mycelium density. However, higher millet concentrations (50% and 75%) tended to reduce growth efficiency due to excessive moisture content. This study recommends using millet flour at low concentrations to improve the efficiency of sustainable F1 oyster mushroom seed production.

Abstract

Sandy soils are widely recognized as marginal agricultural lands due to low water retention, weak nutrient-holding capacity, and limited biological activity. This study aimed to evaluate the effects of integrating biochar and Pleurotus sp. on soil functionality and chili (Capsicum annuum L.) productivity in sandy soil systems. The experiment was conducted using a completely randomized design with four treatments: control (no amendment), biochar alone, Pleurotus sp. alone, and a combined biochar + Pleurotus sp. treatment. Plant growth parameters, leaf chlorophyll content, yield components, and total fruit yield were measured. The results showed that the combined biochar and Pleurotus sp. treatment consistently produced the highest plant height, chlorophyll content, fruit number, and total yield compared with single-input and control treatments. These improvements were attributed to synergistic interactions between biochar-induced improvements in soil physical properties and Pleurotus sp.-driven biological processes, including organic matter decomposition and nutrient mineralization. This study provides empirical evidence that integrating biochar and fungal inputs enhances nutrient cycling efficiency and root–soil–microbe interactions in sandy soils. The findings highlight the potential of biochar–fungal integration as a sustainable and scalable strategy for improving productivity on marginal lands and supporting climate-resilient agricultural systems.

Abstract

Botanical gardens play a strategic role in integrating ecological, spatial, and socio-cultural functions within sustainable agricultural landscapes. This study assesses the functional performance of landscape plants in Enrekang Botanical Garden, focusing on Taman Monumen La Tinro and Taman Wangi, to support sustainable garden management. A mixed-method approach was employed, combining field observations, visual landscape documentation, and visitor perception surveys. Five functional variables were evaluated: ecological, shading, spatial, aesthetic, and conservation functions. The results indicate that aesthetic and spatial functions received the highest visitor ratings in both sites, reflecting effective visual organization and spatial clarity of planting design. Shading and conservation functions showed moderate performance, while ecological functions were perceived as comparatively weaker, suggesting limited recognition of ecological services by visitors. Comparative analysis reveals functional differentiation between the two gardens, influenced by layout configuration and vegetation composition. These findings highlight a functional imbalance between visual-spatial dominance and ecological-conservation roles. The study contributes novelty by integrating visitor-based functional assessment into botanical garden landscape evaluation, offering an applied framework to enhance sustainable, multifunctional landscape management in integrated agricultural systems.
