Abstract/ Executive Summary:

An experiment was conducted to study the effective method of pollination and planting material in pointed gourd in the project site of collection, evaluation, conservation and utilization of land races of some important vegetables and fruits in Bangladesh (CVFB), Horticulture farm Bangladesh Agricultural University, Mymensingh, Bangladesh during the period July 2004 to December 2005. As pointed gourd is a dioecious crop, so pollination is the most important factor for successful production. Hand pollination is the best method of pollination because 98%fruits occur by this method The tip cutting is the most effective planting material in pointed gourd production because 94% plants regenerated by this material but tuberous roots is as well as the effective means of planting material because 74%plants were successfully propagated by this means. Farming practices including land preparation, propagation, fertilization, weeding, mulching, staking and other management practices were as usual. Farmers applied fertilizers and irrigation more judiciously.

Location: Horticulture farm Bangladesh Agricultural University(BAU), Mymensingh, Bangladesh

End Date: 00-12-2005

Program Area: Crop-Soil-Water Management

Commodity: Pointed gourd

Objectives:

To find out the effective method of pollination and means of planting materials in case of pointed gourd cultivation in Bangladesh.

Methodology:

The experiment was conducted at Horticulture Field Laboratory, Bangladesh Agricultural University, Mymensingh Bangladesh during the period July 2004 to December 2005. The experimental site is located at 24.75N latitude and 90.5E longitude at a mean of 18m above the sea level belonging to the non-calcareous dark grey flood plain soil under the Agro-ecological region of the Old Brahmaputra River. The experiment was laid out in a randomized complete block design with three replications. Pointed gourd is a dioecious vegetable so main problem is pollination. Generally growers practices natural pollination system but sometimes they fail to get production. Development of hermaphrodite variety can be remedy of this problem. So find out effective method of pollination in case of pointed gourd is our desire. The treatments were (i) directly hand dusting of pollen (male flowers collection and touching to the female flowers) (ii) Spraying pollen grain solution (male flowers collection and pollens are removed by shaking and made solution) and (iii) natural pollination system (where pollinators honey bee, flies and ants etc move freely towards the flowers). In noon, the immature female flowers which will be matured next day were covered with polyethylene pack to hamper pollination and next morning matured male flowers picked and opening cover of female flowers and touched male flowers for occurring pollination again covers the female flowers as previous process. Several male flowers picked and dusting their pollens into a water jar for making pollen solution and prepared mixtures sprayed to previously cover female flowers and tagged as same process. The unfertilized female flowers tagged and allowed all pollinators for pollination. The all three types data were recorded and calculated for effective methods of pollination determination .

Achievement/Findings:

Hand pollination is the best method of pollination because 98%fruits occur by this method. The tip cutting is the most effective planting material in pointed gourd production because 94% plants regenerated by this material but tuberous roots is as well as the effective means of planting material because 74% plants were successfully propagated by this means.
