The Endophytic bacteria as a biofertilizer agent can minimize the use of chemicals from synthetic fertilizers. aim this research was to study density, diversity and ability endophytic coffee plants that have potential produce IAA. Root samples were obtained in UB Forest (UBF), Sumberwangi, Malang. root surface sterilized then crushed with blender. isolated tested for their results 18 isolates IAA-producing bacteria. KAA6 Isolate produced highest concentration IAA 10.73 ppm at 48 hours incubation followed by KBA3 isolate which 12.78 72 incubation. be further optimized used an eco-friendly agent.

Coffee yield exhibits plant-level variability; however, due to operational issues, especially in smaller operations, the scouting and management of coffee yields are often hindered. Thus, a cell-size approach at field level is proposed as simple efficient solution overcome these constraints. This study aimed present feasibility characterize spatio-temporal production based on soil plant attributes (biennial effects) assess strategies for enhanced fertilization recommendations economic results. The was conducted using database composed from four harvest seasons plantation southeast region Brazil. We used small plots cells, where soil, leaf, samples were taken, average value each variable assigned cell. results indicated that macro- micronutrient contents leaves exhibited heterogeneity between suggesting customized tree practices could be employed. sampling strategy identified regions varying over time associated them with their biennial effect, enabling identification profitable areas direct resource input subsequent seasons. optimized recommendation potassium phosphate fertilizers farms, demonstrating localized feasible even low spatial resolution. proved adequate two farms can applied scenarios limited resources high-density sampling, small- medium-sized farms.

The process of evaluating the soil quality is complex and impacted by a variety physical, chemical, biological indicators as well how they interact over time, particularly throughout different cultivation periods. main objective current investigation to examine various organic farming practices affect at selected farms times. study sites in Egypt were represent two great groups (Torripsamments Haplotorrerts). Moreover, have periods management practices. Soil samples collected from five uncultivated each group control. After analyzing lab, assessed used calculate Quality Index (SOI). Principal Component Analysis (PCA) was obtain minimum data set needed for evaluation. length Torripasament raised SQI value physical chemical following order: 2 years > 6 10 13 years. Similar Torripsament, most sensitive assessment Haplotorrert found be respiration, microbial biomass C, quotient, matter, characteristics quality. Results also indicated that improves studied both soils (Torripsamment Microbial Biomass (MBC), Quotient (MQ), aspects index (SQI) Torripsamment affected mostly indicators, while affecting Haplotorrerts. best score 17
