The present investigation was carried out on “Effect of different organic manures and PGPR consortium on growth and yield of bottle gourd (Lagenaria siceraria MOL. STANDL.) cv. ABG-1” at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat during summer-2018. The experiment was laid out in Randomized Block Design with factorial concept (FRBD) replicated thrice with six level of organic manures application and two level of PGPR consortium of total 12 combination. The control [75:50:50 NPK kg/ha + FYM 15 t/ha (RDF)] treatment was taken separately means without combination under experimentation. The experimental result revealed that growth and flowering parameters of bottle gourd viz., number of branches/plant (14.38), number of female flowers/plant (3.16), girth of fruit (23.85 cm), length of fruit (30.93 cm) and yield parameters viz., number of fruit/plant (8.78), average fruit weight (637.79 g), yield per plant (5.59 kg) and yield (27.84 t/ha) were found superior with the treatment of M₁ (100% RDN from vermicompost) and it was remained at par with the treatment M₅ (100% RDN from castor cake) and M₃ (100% RDN from FYM). PGPR consortium (1l/ha) showed the best result to growth and flowering parameters viz., minimum days taken for germination (7.60), maximum number of branches/plant (13.95), number of female flowers/plant (3.01), girth of fruit (23.06 cm), length of fruit (29.74 cm) and yield parameters viz., maximum number of fruit/plant (8.40), average fruit weight (609.38 g), yield per plant (5.14 kg) and yield (25.73 t/ha) under experimentation.
