Abstract
The experiment entitled “Effect of boron and growth regulators on growth, yield and quality of bottle gourd (Lagenaria siceraria (Molina) Standl.)” was conducted during summer season of 1999 at vegetable section of Horticulture Garden under Faculty of Agriculture, Birsa Agriculture university ,Kanke ,Ranchi in randomized block design in factorial fashion having fourteen treatment combination replicated thrice with an objective to increase yield and quality of bottle gourd cv G-2 .The seed was soaked in boron (0.05%) solution and the foliar spray of PGRs (GA,MH & Ethrel ) in two different level (50& 100ppm)of each at 2 and 4 –true leaf stages.
The vegetative characters of bottle gourd like, vine length, number of leaves, number of nodes and intermodal length were significantly superior by application of GA (100ppm). Seed soaking of boron (B1) was also found to have significantly effect in increasing number of leaves and intermodal length on main vine. The best treatment combination B1GA100 (boron 0.05% and Gibberellic acid 100ppm ) regarding overall vegetative characters .The number of branches was significantly in ethrel (100ppm) and the best treatment combination was B1Ethrel100. The earliest flower initiation was in GA 100 ppm and MH100ppm both. While the best combination wasB1MH100.The first female flower appearance and node number of first flower (male and female) were significantly lowered by etherl 100 ppm and boron both.
Among the quality and yield attributing characters like fruit maturity,fruit length ,fruit diameter, fruit weight and fruit yield per vine as well as estimated total fruit yield per hectare were found to be signicivantly effect by ethrel 100 ppm as well as boron and the best treatment combination was B1ethrel100. The number of fruits per vine was observed maximum in B1GA100 (4.00) followed by B1Ehrel 100(3.93).
Interaction effect of PGRx B) was found to be non-significant for all the characters . So far as the economic of the trial was concerned the treatment combination B1 Ethrel 100 gave the maximum net return (Rs. 40.475.00 per hac) as well as the benefit cost ratio of 2.65.Based on these observation it could be suggested that the significant increase in growth,yield and quality would be obtained by the spraying of ethrel 100ppm and 2 and 4 true leaf stages along with seed soaking by boron (0.05%) for 12 hours. However more experiments are needed to confirm the result.
