Abstract/ Executive Summary:

A field experiment was conducted to evaluate the growth and yield of Okra vegetable grown in association with Lemon and Guava tree based Agroforestry system. The experiment was located at the Char Kalibari, Mymensingh and the duration of the study was June 2012 to November 2012. This study was conducted using a Randomized Complete Block Design (RCBD) with four replications. Different distance from tree base was treated as different treatment. Three different distance category like 0-2.5 ft, 2.5-5.00ft and 5-7.5 ft from tree base were the three different treatment of the study. There was a control treatment i.e. Okra was cultivated in the open field condition (without tree). So the four treatment of this study were T₀ (open field condition referred as control), T₁ (2.5 ft distance from the tree base), T₂ (5 ft distance from the tree base) and T₃ (7.5 ft distance from the tree base). Growth of Guava and Lemon tree also observed during the Okra growing period. The result showed that yield of Okra was gradually increased with increasing distance from both of the tree base. Yield of Okra was highest in open field condition. However, yield of Okra in association with Guava reduced by 2.25, 22.26 and 38.89% yield in 5-7.5 ft, 2.5-5 ft and 0-2.5 ft distant area, respectively. On the other hand, Okra yield reduced 6.8, 26.6 and 43.7% yield in 5-7.5 ft, 2.5-5 ft and 0-2.5 ft distance from Lemon tree base, respectively. Performance of Okra was relatively better along with Guava compare to Lemon tree. The Okra yield difference was 5-7% higher in association with Guava. Regarding to the tree growth, both Guava and Lemon tree growth were better in open field condition compare to tree-vegetable combined situation. Therefore, different tree-crop based Agroforestry system performance had varied greatly. According to the result of this study, Okra yield was better in Guava-Okra based Agroforestry system; however, the performance of Lemon-Okra was also revealed better result. The tree growth was better in open field condition but the total crop and tree yield showed that Agroforestry system is more prfitable than other monoculture of agriculture or forestry production system.

End Date: 00-11-2012

Program Area: Farming System

Commodity: Okra, Lemon, Guava

Objectives:

1. To observe the morphological behaviors, yield and yield attributes of the Okra grown in association with Guava and Lemon tree.

Methodology:

Location of the study area: The experiment was carried out at Char Kalibari belongs to the Mymensingh Sadar Upazilla during the period from June 2012 to November 2012. The place is geographically located at about 24°75" North latitude and 90°50' East longitudes. Total area of this district is 4363.48 km² and situated on the west bank of Brahmaputra River. This district has total 12 upazila and the studying area i.e. Char Kalibari belong to the Mymensingh sadar upazila. The geographical position of char kalibari located between 24?45'- 24?45'40'' North and 90?24'4''- 90?24'44'' East Latitude. It is an attached Char land which has three distinct elevations i.e. upper elevation is relatively stable chnar, while the middle and lower elevation remained inundated during the rainy season in each year. Only upper portion is suitable for cultivation of vegetables during summer and winter season. Soil characteristics: The topography of the field was medium high land above flood level belonging to the Old Brahamaputra Floodplain Agro-Ecological Zone-9. It is characterized by non calcareous dark grey flood plain soil having pH value from 6.5 to 6.8 and the soil texture is silty loam. It appeared cold but readily broken when pulverized. Climate and weather: The climate of the location was characterized by relatively high temperature and heavy rainfall during Kharif or summer season (April to October) and low temperature and little rainfall during Rabi or winter season (November to March). Tree and plant materials: In this study, previously established 2 years old Lemon and Guava were used as tree components. The seeds of Okra variety BARI Dherosh-1 (summer vegetable) were used as plant materials in this study. Experimental design and treatment combination: The experiment was laid out following the Randomized Complete Block Design (RCBD) design with single factorial arrangement with three replications. Four treatments of this study are used such as T₀ (Okra grown without lemon and guava tree base), T₁ (Okra grown 2.5ft distance from the tree base), T₂ (Okra grown 5ft distance from the tree base) and T₃ (Okra grown 7.5ft distance from the tree base). considered for data collection. Dry yield was measured after complete drying the samples in the oven at 700 C from representative samples and it was converted as tha^-1. Dry yield was calculated using the following formula: Total dry weight = (subsample oven dried weight/subsample fresh weight) x total fresh weight. Statistical analysis: The data were collected from the experiment at different stages of various growths, and analyzed statistically by using MASTATC software package to find out the statistical significance of the experimental results. The means for all the treatments and analysis of variance of yields of the summer vegetables was calculated by Duncan's Multiple Range Test (DMRT)

Achievement/Findings:

Growth of Guava and Lemon tree also observed during the Okra growing period. The result showed that yield of Okra was gradually increased with increasing distance from both of the tree base. Yield of Okra was highest in open field condition. However, yield of Okra in association with Guava reduced by 2.25, 22.26 and 38.89% yield in 5-7.5 ft, 2.5-5 ft and 0-2.5 ft distant area, respectively. On the other hand, Okra yield reduced 6.8, 26.6 and 43.7% yield in 5-7.5 ft, 2.5-5 ft and 0-2.5 ft distance from Lemon tree base, respectively. Performance of Okra was relatively better along with Guava compare to Lemon tree. The Okra yield difference was 5-7% higher in association with Guava. Regarding to the tree growth, both Guava and Lemon tree growth were better in open field condition compare to tree-vegetable combined situation. Therefore, different tree-crop based Agroforestry system performance had varied greatly. According to the result of this study, Okra yield was better in Guava-Okra based Agroforestry system; however, the performance of Lemon-Okra was also revealed better result. The tree growth was better in open field condition but the total crop and tree yield showed that Agroforestry system is more profitable than other mono culture of agriculture or forestry production system.
