Meeting the society’s increasing demand for food and energy require sustainable and readily�ᅠ�ᅠ available sources. The green revolution has been instrumental in creating sufficient crop productivity and maintained soil fertility. In the context of sustainable agriculture, the utilization of biofertilizers is of paramount importance. Commercial biofertilizers (bacteria/fungi) and their association directly or indirectly provide a beneficial effect on plant growth by increasing the supply and/or availability of nutrients to the host plant. However, large scale and field application of plant growth promoting microorganisms (PGPMs) as bioinoculant are still limited. Some of the major limitations are related to poor quality, short shelf-life and the lack of applicable formulation for bioinoculant. Immobilization using polymer matrix has been promising in enhancing protection, shelf life and slow release of bioinoculants. Furthermore, bacterial growth after immobilization in the polymer matrix is promoted with the supplementation of essential nutrients. The present review highlights the beneficial impacts of liquid formulation and exploiting alginate immobilized PGPMs for eco-friendly and sustainable crop production.
