Abstract
Prayagraj is situated at the bank of river Ganga and Yamuna, having humid, hot weather during summer and severe winter that comes under sub-tropical climatic zone. Cherry tomato is a climate-sensitive crop grown successfully in India’s hilly and foothill region. In climatic zone such as Prayagraj, it experiences natural stresses which hamper its growth and development finally affecting yield and quality. PGPRs are the natural source growth regulator which has been found effective in increasing growth and is also known for reducing stresses. Bacillus and Pseudomonas are well-known PGPR that are effective in mitigating stress effects and improving growth and yield. This study is designed to understand Bacillus and Pseudomonas’ efficacy in improving cherry tomato growth and yield in sub-tropical conditions like Prayagraj. Our finding states that Bacillus + Pseudomonas soil application effectively increases plant height (117.33cm), Number of Leaves (106.60), Number of fruits/plant (220), Fruit weight (8.78g), chlorophyll a(0.68 mg/g F/w), chlorophyll b(0.36 mg/g F/w), Carotenoids (0.55 mg/g F/w), Lycopene (156.33µg/g) than compared to control. We also find that soil application was more successful than foliar application.
