ABSTRACT

A field trial was conducted at the Multi location Testing (MLT) site, Joypurhat during Rabi, 2015-16 to
evaluate the performance of pointed gourd varieties under farmer’s field condition in Barind tract of
Bangladesh. Three pointed gourd varieties viz. BARI Potol-1, BARI Potol-2 and Local (check) variety were
evaluated in the study. The highest pointed gourd fruit yield (27.5 tha-1), gross returns (TK. 551600 ha-1)
were found from BARI Potol-1 which was statistically differed to other varieties. The lowest pointed gourd
fruit yield (21.59 tha-1), gross return (TK. 431800 ha-1)) were obtained from local/cultivated variety. Result
revealed that, the shape of fruit BARI Potol-1 was also differed from the other varieties. So, the cultivation of
BARI Potol-1 can be expanded to meet the vegetables demand in barind tract of Bangladesh.
Key words: BARI released variety, pointed gourd, fruit yield

Introduction
Vegetables compared to other foods offer a cheap food source. It can even be produced a small amount of
land and also in a residential area. It can be grown within a short period and more than one crop can be
grown within a harvest season. There are a large number of vegetables with different varieties that can be
grown throughout the year. However, the largest number of vegetables is grown in the winter season.
Vegetables are generally labor-intensive crops and therefore offer a significant promise to generate more
employment in rural areas. Bangladesh’s climate and soil is very suitable for growing vegetables all year
round (Akter et al., 2011). Nearly 100 different types of vegetables, including both local and foreign
origins, are grown in Bangladesh. Vegetables are important for nutrition, economy and food security.
Vegetables can be considered an important for this economy because of the remarkable contribution to
increasing the income from foreign currencies and occupies an important position among the products
exported from Bangladesh. Vegetables contribute 3.2% of the gross domestic product of agriculture (BBS,
2009). Bangladesh earned US $ 41.11 from agricultural exports, which contributed 0.54% to total export
earnings (BER, 2008). But still we are in shortage to cultivate vegetables in summer period of Bangladesh.
Pointed gourd (Trichosanthes dioica Roxb) under the family of Cucurbitaceae is being cultivated in
summer season as one of the most nutritive vegetables in Bangladesh. It is grown around 10006.5 ha with
total production of 84096 metric tons and national average yield is 8.40 t/ha during 2014-15 (Anon., 2016).
It is morphologically exception from the other cucurbitaceous species due to its well established
dioeciously vegetative means of propagation (Awal et al., 2005). It is a good source of vitamins and
minerals. It contains 92.4% water, 0.5% minerals, 3.0% frbre, 2.4% protein, 0.6% fat and 4.1%
carbohydrate per 100g edible portion. It has also high industrial value as different types of jam, jelly and
pickles can be made from this vegetable. It has also a good medicinal value. It is easily digestible, diuretic
and laxative invigorates the heart and brain and is useful in disorder of the circulatory system (Malek,
2009). It was reported that pointed gourd possesses the medicinal property of lowering the total cholesterol
and blood sugar (Sharma et al., 1988). However, in Bangladesh the average yield of pointed gourd in
Bangladesh is low compared to other countries of the world. This low yield may be due to the cultivation of
the low yielding local varieties, incidence of diseases and insects, lack of technical knowledge etc.
Recently, BARI has developed two high yielding varieties, BARI Potol-1, BARI Potol-2 and one hybrid
