Abstract/ Executive Summary:

An experiment on the effect of artificial pollination and different levels of hormone application on the fruit set and yield of bottle gourd was carried out at the Central Research Station, BARI, Gazipur. Besides vine length and days to first harvest, all the parameters were influenced significantly due to the different treatments. The plants treated with NAA-200 ppm produced fruits of maximum length and girth, whereas fruits of minimum length and girth in control. Number of fruits per plant were also found maximum in plants where NAA-200 ppm was applied. Hormone application @ 200 ppm produced maximum yield (48.15 t/ha). Hand pollination increased the yield of bottle gourd reasonably over the others.

Keywords: Bottle gourd, Yield, Pollination, Hormone

Location: Bangladesh Agricultural Research Institute, Gazipur

Start Date: 06-10-1988

End Date: 00-00-1990

Program Area: Crop-Soil-Water Management

Commodity: Bottle gourd

Objectives:

To see the effect of different pollination methods and hormone application on the fruit set and yield of bottle gourd.

Methodology:

The experiment was conducted at the farm of Central Research Station of the Bangladesh Agricultural Research Institute, Gazipur during the rabi seasons of 1988-89 and 1989-90. A promising line of bottle gourd (BG (033) was used in the experiment. The six different treatments, such as bee pollination, hand pollination, NAA-100 ppm, NAA-200 ppm, NAA-300 ppm and control (natural pollination) were assigned in the unit plots (4m x 4m) providing 2m x 2m spacing following RCB design with four replications. Seeds of the line BG 0033 were sown directly on 6 October in both the seasons, The crop was fertilized as per recommendation of Rashid (1983). Bee hive boxes were used for bee treatment and mosquito nets were used for both bee pollination and hormone treatments. Hand pollination was done by picking male flowers, detaching the petals and subsequently rubbing the anthers into the stigma of female flowers between 4.30-6.00 p.m. Female flowers were bagged with perforated polythene bags just after hand pollination to avoid out crossing. For hand pollination, the male and female flowers were used from different plants. The fruits were harvested at their harvestable maturity stage. Data recorded on different parameters were analyzed statistically and the means were separated by DMRT.
