A review on seed priming to combat climate variability in agriculture

Abstract

Global agriculture faces immense challenges due to climate change, which causes unpredictable weather patterns, decreased agricultural productivity, and decreased food security. Seed priming is critical in combating climate variability because it has emerged as a promising method for improving seed germination and agricultural resilience. This review evaluates the efficiency of several seed priming techniques, including hydro-priming, halo-priming, osmo-priming, bio-priming, chemical priming, and hormone priming. These techniques improve seedling vigor, stress tolerance, and overall crop yield. Seed priming increases germination rates and resistance to biotic and abiotic stresses, such as salinity and drought, while improving agricultural output and disease resistance. Seed priming reduces the demand for chemical pesticides and fertilizers by increasing soil quality and nutrient absorption, which supports sustainable agriculture. This review highlights the potential benefits of seed priming as a practical, affordable, and practical strategy to reduce the negative effects of climatic variability on agriculture. Future studies should focus on developing the best priming techniques for diverse crop varieties and conditions, as well as examining the combined impacts of various priming strategies. Seed priming will be crucial to preserving food security and agricultural sustainability in the face of ongoing climate change
