Abstract: The present investigation entitled “Influence of plant growth regulators and boron on performance of bottle gourd [Lagenaria siceraria (Mol.) standl.] var. Pusa Naveen” was conducted during Kharif season, 2016 at the Instructional Farm of Vegetable Science, College of Horticulture and Forestry, Jhalawar, Rajasthan. The experiment consisting 15 treatments with 2 growth regulators NAA, Ethrel and borax each at two levels (NAA 100, 200ppm, Ethrel 250, 500ppm, Borax 0.05, 0.1% and control) were replicated three times in a Randomized Block Design keeping plot size of 6 m x 3 m. The seed sowing was done on 4 July, 2016 in the furrow spaced at 3 m apart maintaining a plant to plant distance of 0.6 m. The observations were recorded on growth, yield and quality attributes namely i.e. vine length (m), vine diameter (mm), chlorophyll content in leaves (mg/100g), number of nodes on main vine, number of primary branches/plant, node at which first male and female flower appeared, days to anthesis of first male and female flower, days to first harvesting, number of male and female flowers per vine, Fruit setting (%), Sex : ratio, fruit length (cm), fruit diameter (cm), fruit weight (g), number of fruits per vine, fruit yield per vine (kg), fruit yield per hectare (q), B:C ratio, TSS (0Brix), ascorbic acid content (mg/100 g) and crude protein content (%). The application of plant growth regulators and boron had influenced significant effect on growth, yield as well as quality attributes over control. The results showed that treatment T8 (borax 0.05% + Ethrel 500 ppm) was found most effective in the increasing, vine diameter (20.95 mm), number of primary branches per plant (15.70), female flower per vine (18.90), fruit length (31.50 cm), fruit diameter (6.87 cm), number of fruit per vine (8.87), fruit weight (830.94 g), fruit yield per vine (7.36 kg), fruit yield per ha. (408.61 q), TSS (3.330Brix) and ascorbic acid (7.60 mg/100g) and in the decreasing, male flowers per vine (78.50), node at which first male (13.01) and female flower appear (17.17), days to anthesis of first male flower (41.67 days) and female flower (42.03 days), days to first harvesting (48.17), sex ratio (4.14). The maximum fruit yield (408.61 q/ha), net return (Rs. 241936.53 per ha.) and B:C ratio (3.74) were also recorded under treatment T8 over control.
