To study the effect of Plant Growth Promoting Rhizobacteria (PGPR) on growth and yield of Sponge Gourd; a field experiment was conducted on the research farm of the Department of Horticulture, SHUATS, Prayagraj during 2019-20. Four PGPR strains, Azospirillum, Phosphorous Solubilizing Bacteria, Bacillus subtilis, and Pseudomonas fluorescens are studied and replicated thrice in a Randomized Block Design in 3 x 2 m2 plot size. Early germination was observed in Azospirillum treatment followed by the Bacillus subtilis application recorded 4.07 and 4.14 days respectively. The study revealed that the maximum vine length (6.32m) and (6.25m) was reported in the double application of Bacillus subtilis (basal+30DAS) and double application of Pseudomonas fluorescens (basal+30DAS). Number of primary branches was maximum (5.87) in plants supplied with the double application of Bacillus subtilis as (basal+30DAS). Bacillus subtilis (basal+30DAS) were found to be the best treatment for the fruit length, girth, and weight with 25.05cm, 4.84cm, and 131.83gm respectively followed by the single application of Bacillus subtilis with 24.61cm, 4.71cm, 123.91gm respectively. Application of Bacillus subtilis (basal+ 30DAS) produced the maximum yield/plant and yield/ha (4.84kg) and (132.65q/ha) respectively. Among the different PGPR studied, double application of Bacillus subtilis (basal+30DAS) performed best for flower, fruit, growth, and yield characters. The results of the experiment revealed that PGPR has a wide range of beneficial effects on improving the growth and yield of Sponge gourd.
