GRICULTURE is very important for humanity as it supplies human needs ranging from food to fiber, feed for animals and energy. The production of seedlings is of great agricultural importance, especially in horticultural nurseries. Producing vigorous and healthy seedlings like banana and strawberry using biological nanofertilizers (bionanofertilizers) is presented in this mini-review. Due to their properties, bionanofertilizers have received increasing interest in agriculture, particularly during transplanting or the production of seedlings. Many studied seedlings attributes, such as the plants' antioxidants systems, nutritional status, and quality parameters of seedlings have been improved through the use of bionanofertilizers. The most important impacts of bionanofertilizers may include enhancing production of seedlings or plants under biotic and abiotic stresses through the improvement of attributes like physiological, biochemical, and molecular characteristics. This diagrammatic mini-review will focus on biological nanofertilizers and their potential uses in horticultural crop production.
