Abstract/ Executive Summary:

A field experiment was conducted at the Agroforestry Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during 08 January 2009 to 08 April 2009 to evaluate the performance of Okra plant under litchi based agroforestry system. The treatments were three okra variety viz. hybrid okra variety, BARI-1 and local okra variety, which were used as ground layer crop. There was also control (sole cropping) treatment. This experiment was laid out using two factors Randomized Complete Block Design (RCBD) with three replication. The aim of the experiments was to study the growth performance and selection of potential okra variety under litchi based agroforestry system. The yield contributing parameters were maximum in sole cropping of hybrid okra. The yield was highest (10.24 t ha^-1) in monocropping of hybrid okra and the lowest yield (4.24 t ha^-1) was found in T₆ (Litchi + Local okra variety). But the litchi based agroforestry system ensures higher return and more sustainable than sole cropping. The suitability of okra variety may be ranked as Okra hybrid variety > BARI-1 okra > Local okra variety.

Keywords: Okra variety, Litchi tree, Agroforestry system

Location: Agroforestry Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur

Start Date: 08-01-2009

End Date: 08-04-2009

Program Area: Farming System

Commodity: Litchi, Okra

Objectives:

1. Production of okra in association with litchi tree may be an ideal combination of two high value crops. Scientific research is needed for investigating interaction effects of Litchi-Okra production system.

Methodology:

The experiments were conducted in Agroforestry Research Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur during 08 January 2009 to 08 April 2009. The site was between 25º 13´ latitude and 88º 23´ longitude, and about 37.5 m above the sea level. The experimental plot was situated in a medium high land belonging to the old Himalayan Piedmont Plain area (AEZ 01). Land was well-drained and drainage system was well developed. The soil texture was sandy loam in nature. The soil pH was 5.1. The aim of the experiment was to evaluate the performance of Okra plant under litchi based agroforestry system. The treatments include three okra variety viz. hybrid okra variety, BARI-1 and local okra variety, which were used as ground layer crop. There was also control (sole cropping) treatment. This experiment was laid out in the two factors Randomized Complete Block Design (RCBD) with three replications. The hybrid okra variety having brand name US Agriseed Tm. This seeds were marked by Seed Works India Pvt. Ltd. On the other hand, BARI-1 was collected from Bangladesh Agriculture Research Institute, Gazipur and the local okra variety was collected from local seed market of Dinajpur. The age of the litchi trees were five years with spacing of 5m × 5m. Each plot size was 2.5m × 2.5m. Adjacent plots and neighboring blocks were separated by 0.5m × 3m, respectively. The land was prepared thoroughly by spading to obtain a good tilth. All weeds and stubbles were removed from the filed and bigger clods were broken into smaller pieces. Recommended doses of fertilizers were used for the respective Okra variety and intercultural operations were done as and when necessary to keep the crop weed free and to pulverize the soil. Heavy irrigation was given three times at 15, 30 and 50 DAS, respectively. Data were statistically analyzed using the (ANOVA) “Analysis of Variance” technique with the help of the computer package MSTAT. The mean differences were adjusted by the Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

Fruit yield (t ha^-1) of okra significantly varied under Litchi based agroforsetry system. Significantly, the highest yield (10.24 t ha^-1) was found in sole cropping of okra hybrid variety that was followed by (7.685 t ha^-1) in T₂ (sole cropping of BARI-1 variety). The lowest yield (4.24 t ha^-1) was found in T₆ (Litchi + Local okra variety).
