Abstract
A field research was carried out in the Department of Vegetable Science, Odisha University of Agricultural and Technology (OUAT), India, during the 2018 kharif season to investigate the impact of various sources of nutrient management on the vegetative growth and flowering of Kharif Season Bottle Gourd. The research project was set up in a randomized block design with replicated three times of twelve treatment. According to the results, the maximum vine length (529.33cm) was noted in treatment T10 (100% RDF + FYM @ 7.5 t ha-1+ Biofertilizer), maximum number of Primary branches (8.97), internodal length (15.83),minimum no. of node bearing 1st male flower (4.67), minimum no. of node bearing 1st female flower (7.67) was recorded in treatment T12 (50% RDF + FYM @7.5 t ha-1+ Vermicompost @ 2.5 t ha-1+ Biofertilizer) whereas minimum number of days until the 1st male flower (46.33 days ),minimum days to the first female blossom (49.00days), minimum days to 1st Fruit set (50.67days) were found significant as vegetative, flowering parameters and Sex ratio (3.10) while the lowest response for these parameters was obtained with T1 (control).
