Abstract/ Executive Summary:

An experiment was conducted at the Regional Agricultural Research Station, Hathazari, Chittagong during the period from December, 1981 to April 1982 to investigate the possibility of increasing the yield of pumpkin by supplementing natural pollination with hand pollination. The treatment natural-cum-hand pollination' produced about 50% more yield as well as number of fruits than of natural pollination.

Keywords: Pumpkin, Artificial Pollination, Yield

Location: Regional Agricultural Research Station, Hathazari, Chittagong.

Start Date: 00-12-1981

End Date: 00-04-1982

Program Area: Crop-Soil-Water Management

Commodity: Pumpkin

Objectives:

To determine the extent of increase in pumpkin yield by supplementing natural pollination with hand pollination.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, Hathazari, Chittagong between the period from December, 1981 to April, 1982. The variety used was a local one. There were three treatments viz. (a) Natural pollination, (b) artificial pollination and (c) Natural cum-hand pollination. The treatments were replicated three times. There were 9 plants in each replication. The seeds were sown in pits 3m apart on 15 December, 1981. Hand pollination was done by picking male flowers, detaching the petals and then gently rubbing the anthers onto the stigma of flowers at anthesis at 6 A.M. In case of 'artificial' pollination the female flowers were bagged with perforated polythene bags just after hand pollination to avoid natural pollination. Whereas, the female flowers of the treatment artificial-plus-natural pollination were left exposed after pollination. In case of hand pollination the male and female flowers used were from two different plants. The fruits were harvested when they were fully matured. The data were taken from individual plants. The characters observed were (1) number of fruit per plant (2) weight of individual fruit and (3) the size of fruit.
