Abstract/ Executive Summary:

To maximize the production in agroforestry system it is needed to explore the best possible tree-crop interactions. Therefore, an experiment was conducted at the Char Kalibari which is situated by the side of Brahmaputra River Sadar Upazila, Mymensingh, during the period from November 2012 to March 2013, under the Department of Agroforestry, Bangladesh Agricultural University, Mymensingh. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications having four treatments. Different distances from the tree base were considered as different treatments. There was a control treatment i.e. bottle gourd was cultivated in the open field condition (without tree). Four treatments of this study were viz., T₀ (open field condition referred as control), T₁ (0-1.5 feet distance from the tree base), T₂ (1.5-3.0 feet distance from the tree base) and T₃ (3.0-4.5 feet distance from the tree base). One tree species viz., Akashmoni (Acacia auriculiformis), which is 3 years old was used as test species in this experiment. The result showed that morphological characteristics viz. plant height, no. of leaves per plant, leaf size, leaf area (cm²), number of flower per plant, number of fruit per plant, fruit length (cm), fruit girth (cm), fruit weight (g) of bottle gourd was less vigorous near the Akashmoni tree base. The results also showed that in association with Akashmoni, tree both fresh and dry yield of bottle gourd was gradually increased with increasing distance from the tree base; while it were 29.83 t/ha and 3.59 t/ha, respectively in open field condition. Fruit yield of bottle gourd in association with Akashmoni tree reduced 64.93%, 48.43% and 15.47% in 0-1.5 feet, 1.5-3.0 feet and 3.0-4.5 feet distant area, respectively. Thus it comes into the point that the yield performance of bottle gourd was better in open field condition comparing to Akashmoni.

Keywords: Bottle gourd, Akashmoni (Acacia auriculiformis), Agroforestry system

Location: Char Kalibari which is situated by the side of Brahmaputra River Sadar Upazila, Mymensingh

Start Date: 00-11-2012

End Date: 00-03-2013

Program Area: Farming System

Commodity: Akash moni, Bottle gourd

Objectives:

1. To meet up the demand of vegetable as well as timber and fuel wood, farmers will be cultivate these plant species combindly as agroforestry system.

Methodology:

Location of the study area: 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 the three years old previously established Akashmoni (Acacia auriculiformis), trees was used as test tree components and Bottle gourd (Lagenaria vulgaris) was used as plant materials. On the others hand the seeds of bottle gourd were collected from International Seed Fair in Bangladesh Agricultural University Campus. Tree management: The study was done under 3 years old Akashmoni, tree saplings. At first soils of the base of trees were loosening very well. 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. Experimental design and treatment combination: The Experimental design was Randomized Complete Block Design (RCBD) with three replications. Four treatments were used in this study which is were T₀ = Open field referred to as control, T₁ = 0-1.5 feet distance from the tree T₂ = 1.5-3.0 feet distance from the tree and T₃ = 3.0-4.5 feet distance from the tree. A characteristic feature of the experimental lay out around each tree has been grown in open field without vegetables. Land preparation: The experimental land was first opened on 01 November, 2012 and the operation was done by spade. Then the land was fallow for few days. All crop residues and weeds were removed from the field and finally the land was properly leveled. The land should be prepared thoroughly by five to six ploughings. Crop establishment and management Seed Sowing: Bottle gourd seeds were directly sown in the experimental plot on 5th November 2012. Intercultural operations: Weeding, thinning, irrigation, fertilization, pest and disease management were done necessarily when required. Harvesting and data collection: Plant samples of Bottle gourd were collected from all the respective plots. Four plants of bottle gourd were selected from each 1m² plot for data collection. Data were collected at 35, 55 and 120 Days after sowing. The following plant characters of bottle gourd were recorded as vein length, no of leaf, no of flower (male and female), no of branch, fruit length, no. of fruit, fruit diameter, fruit weight, fresh weight of stem and leaf, dry weight of stem and leaf. Data analysis: Data regarding various parameters were statistically analyzed by the computer using statistical package programme MSTAC-C. Mean comparisons were done by DMRT (Duncan's Multiple Range Test) at 5% level of significance.

Achievement/Findings:

The result showed that morphological characteristics viz. plant height, no. of leaves per plant, leaf size, leaf area (cm2), number of flower per plant, number of fruit per plant, fruit length (cm), fruit girth (cm), fruit weight (g) of bottle gourd was less vigorous near the Akashmoni tree base. The results also showed that in association with Akashmoni, tree both fresh and dry yield of bottle gourd was gradually increased with increasing distance from the tree base; while it were 29.83 t/ha and 3.59 t/ha, respectively in open field condition. Fruit yield of bottle gourd in association with Akashmoni tree reduced 64.93%, 48.43% and 15.47% in 0-1.5 feet, 1.5-3.0 feet and 3.0-4.5 feet distant area, respectively. Thus it comes into the point that the yield performance of bottle gourd was better in open field condition comparing to Akashmoni.
