Abstract
Seeds are exposed to numerous potentially adverse environmental conditions such as water deficit, high salinity, and extreme temperature. These abiotic stresses affect seed germination and crop productivity. Nowadays, various seed treatments are employed to generate seeds that can withstand these stresses and ensure uniform crop stand. Here, we discuss the application of nontoxic, environmentally safe polymers that can be applied for seed treatment to provide protection to the seed under unfavorable conditions and allow germination to proceed when conditions are favorable. This chapter discusses the applications of various biopolymers and their derivatives for seed priming and coating purposes. These renewable biopolymers can be isolated from agricultural waste residues such as corn cob, rice husk, sugarcane bagasse, wheat straw, and others, which would assist in the management of waste disposal issues. At this stage, the future potential of this seed treatment technology needs to be fully explored for sustainable agriculture practices.
