Abstract

Cotton is commonly known as “White gold” and “King of natural fibre” owing to its higher economic value amid the cash crops. The use of plant growth-promoting rhizobacteria (PGPR) is a promising alternative tool to improve plant efficiency for effective utilization of fertilizers by cotton. PGPR as biofertilizer favours increase in crop productivity in terms of yield and quality. Plant bacterial interactions in the rhizosphere are the determinants of plant health and soil fertility. However, more studies into the impact of seed biopriming on cotton plant growth and development is needed. This study aims to evaluate the potential of seed priming with PGPR strains to promote growth in cotton plants. Shoot length, root length, shoot dry matter, root dry matter, total dry matter, plant growth traits, chlorophyll content and index, soluble protein and normalized difference vegetation index were analysed. The highest shoot length and root length was 47.0 and 19.6 cm and the highest s
