Soil microorganisms play an important role in increasing nutrient availability for maize plants through the processes of nitrogen fixation, phosphate solubilization, and humic acid production. These processes not only increase maize productivity but also reduce dependence on synthetic chemical fertilizers, thus supporting agricultural sustainability. This study explores the benefits of microorganisms such as Rhizobium, Azospirillum, Pseudomonas, and arbuscular mycorrhizal fungi in enhancing nutrient uptake, protecting plants from environmental stress, and improving soil quality. Challenges in the application of microorganism technology include adaptation to diverse environmental conditions and low farmer adoption. However, advances in genomic technology and biotechnology open up opportunities to optimize the benefits of soil microorganisms. The implementation of this microorganism-based technology has the potential to support efficient, environmentally friendly and sustainable maize farming.

This study examines the main pests and diseases that attack cayenne pepper (Capsicum frutescens) plants grown in polybags. In Indonesia, this crop is in high demand for both household and industrial use. Nonetheless, farmers often face challenges from pest and disease attacks, including anthracnose, fusarium wilt and stem rot, leading to reduced yields. The methodology used was a literature review covering various sources related to cayenne pepper. Findings show that important diseases such as anthracnose can reduce yields by up to 80%, while pests such as fruit flies can cause chili fruits to drop prematurely before harvest. Effective pest and disease management is essential to increase the productivity of cayenne pepper cultivated in polybags.
