Abstract/ Executive Summary:

The present investigation was conducted at Char Kalibari, which is situated by the side of Brahmaputra River adjacent to the Bangladesh Agricultural University, Mymensingh during the period from October 2012 to March 2013. The experiment was conducted to evaluate the performance of Bitter gourd (Momordica charantia) in association with mango, guava, and lemon tree at different distance. The experiment was consisted of four different treatments viz. T₀ (open field referred as control), T₁ (<50 cm distance from the tree base), T₂ (50-100 cm distance from the tree base) and T₃ (> 100 cm distance from the tree base). The experiment was laid out in a Randomized Complete Block Design with three replications. Data were collected on morphological and yield contributing characters of the vegetables and were analyzed for evaluation of the treatment effects. In this study, different growth parameters viz. Vine length, number of primary branches per plant, number of leaves per primary baranch, number of fruit per plant, individual fruit weight etc. and yield (fresh and dry) of bitter gourd was observed separately with mango, guava, and lemon trees. It was found that growth and yield of bitter gourd was relatively better in the open field condition compare to in association with all tested fruit tree species. Among the different fruit species, growth of bitter gourd was relatively lower in combination with lemon tree species. In combination with all of these fruit tree species growth of bitter gourd gradually decreased with decreasing distances towards the tree base. Similar trend of variation was also found in case of yield of bitter gourd in combination with these fruit tree species. Highest fresh of bitter gourd was obtained in open field condition which was 4.1 tha^-1. Among the different distances viz. < 50 cm, 50-100 cm and >100 cm distance from the tree base, yield of bitter gourd was decreased towards the tree base. It was found that on an average 47.15, 34.15 and 20.33% yield of bittter gourd was decreased in <50 cm, 50-100 cm and >100 cm distances from tree base compare to open field condition. As growth and yield of bitter gourd was influenced by mango, guava, and lemon tree, growth of these trees was also significantly influenced by bitter gourd. It was recorded that both height and girth increment of these trees were bit better in combination with bitter gourd.

Commodity: Lemon, Guava, Mango, Bitter gourd

Objectives:

1. To investigate the the peroformance of bitter gourd in association with different fruit trees in the char land based agroforestry system.

Methodology:

Location of the experimental site and season: The experiment was carried out at char Kalibari belongs to the Mymensingh sadar upazila during the period from November 2012 to March 2013. The district Mymensingh is located between 24?38'3'' North and 90?16'4'' East Latitude. Total area of this district is 4363.48 km2 and situated on the west bank of Brahmaputra River. The geographical position of char Kalibari located between 24?45' - 24?45'40'' North and 90?24'4''- 90?24'44'' East Latitude. Tree and plant materials: In this study previously established 2.5 years old Mango (Mangifera indicia L.), Guava (Psidium guajava), Lemon (Citrus lemon) trees were used as tree components and one crop Bitter gourd (Momordica charantia) was used as plant materials. The seeds of bitter gourd were collected from International Seed Fair in Bangladesh Agricultural University Campus. Tree management: The study was done under 2.5 years old Mango, Guava and Lemon tree. At first soils of the base of trees were loosening very well and made friable. Weeds were removed from the surrounding of the tree base; insect infected leaves were also removed. Irrigation was done two times in a day by the watering cane. Design and layout of the experiment: Bitter gourd was laid out following the Randomized Complete Block Design (RCBD) with single factorial arrangement of multistoried production system. Four treatments were used in this study and three replications were followed for each treatment for each crop. Each plot was 4.5 m width and 2.0 m length at both sides of selected tree species. Different treatments of this study were; T₀= Open field referred to as control, T₁= < 50 cm distance from the tree base, T₂= 50 – 100 cm distance from the tree base, and T₃= > 100 cm distance from the tree base. Crop establishment: Bitter gourd seeds were sown in the experimental plot on 25 October in separated small seed bed of each plot where each seed bed distance was 0.5 × 0.5 m length and width, respectively. Ten to twelve seeds of bitter gourd were sown in each seed bed. Management practices Only cow dung was applied as manure. The full amount of cow dung was applied at the time of final land preparation. The experimental plots were kept weed free by weeding frequently. The land was irrigated wherever needed by using hose pipe and watering cane to supply sufficient soil moisture for the vegetables. Emergence of bitter gourd seedling was started after 15 days from the date of sowing. Seedlings were thinned out for three times where second and third thinning out was done at 5 days interval from first thinning. After emergence, bitter gourd was thinned out at three times while first thinning was done at 15 days after sowing. No pesticide and fungicide were used in the field for tree-vegetable association. Harvesting: Bitter gourd was harvest after 120 days after sowing. The fruits were harvested at tender stage and before 100% maturity when they are still green. Delay in harvesting causes the fruit to become unfit for marketing. Harvesting is done by hand picking. Bitter gourd was harvested at several picking. Methods of data collection Bitter gourd: Five plants were randomly selected for data collection. The parameters studies were Vine length, number of primary branches/plant, number of leaves/primary branches, number of fruits/plant, weight/fruits (kg) and fresh and Dry weight of fruits (t/ha). Fruit trees: Ten tree samples were selected randomly from all treatments of the plots for data collection. Sample trees were selected at before and after of vegetables cultivation. Tree height (cm) and tree girth (cm) were recorded. Statistical Analysis: The data on various growth and yield contributing characters of the vegetables was statistically analyzed to examine the significant variation of the results due to different parameters. The analysis of variance for each of the character under study was done by F (variance ratio) test for Randomized Complete Block Design (RCBD). The treatments means were compared by DMRT (Duncan's Multiple Range Test) at 5% level of significance.

It was found that growth and yield of bitter gourd was relatively better in the open field condition compare to in association with all tested fruit tree species. Among the different fruit species, growth of bitter gourd was relatively lower in combination with lemon tree species. In combination with all of these fruit tree species growth of bitter gourd gradually decreased with decreasing distances towards the tree base. Similar trend of variation was also found in case of yield of bitter gourd in combination with these fruit tree species. Highest fresh of bitter gourd was obtained in open field condition which was 4.1 tha^-1. Among the different distances viz. < 50 cm, 50-100 cm and >100 cm distance from the tree base, yield of bitter gourd was decreased towards the tree base. It was found that on an average 47.15, 34.15 and 20.33% yield of bittter gourd was decreased in <50 cm, 50-100 cm and >100 cm distances from tree base compare to open field condition. As growth and yield of bitter gourd was influenced by mango, guava, and lemon tree, growth of these trees was also significantly influenced by bitter gourd. It was recorded that both height and girth increment of these trees were bit better in combination with bitter gourd.
