Abstract/ Executive Summary:

A field experiment on okra comprising two spacings (60 x 30 cm and 50 x 30 cm) and seven okra varieties (Sabuj Bangla, Parash-2, Sarash-2, Najuka, Anamika, BARI Dherosh-1 and Supriya) was conducted at the Rangamati Hill District during 2006-2007 to find out the optimum spacing and suitable okra variety for this region. The closer spacing resulted in significantly taller plants than wider spacing. The number of fruits per plant, length, of fruit, diameter of fruit individual fruit yield and fruit yield per plant were higher under wider spacing. But fruit yield per hectare was significantly higher at closer spacing. But fruit yield per hectare was significantly higher at closer spacing. The varieties Sabuj Bangla and Supriya demonstrated better performance in respect of yield components and yield compared to other varieties, out-yielded the standard variety BARI Dherosh-1. The variety Supriya gave higher fruit yield per plant both at closer and wider spacing. All varieties produced higher yield at closer spacing than at wider spacing. The varieties Supriya and Sarash-2 were Apparently free from yellow vein mosaic virus disease, while the varieties BARI Dherosh-1 and Anamika were highly affected by the virus disease.

Keywords: Spacing, Variety, Fruit yield, Okra

Location: Agricultural Research Station, Raikhali in the district of Rangamati.

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Crop-Soil-Water Management

Commodity: Okra

Objectives:

To evaluate the yield potential of six Indian okra varieties under two plant spacing at the hilly region of Raikhali. BARI Dherosh-1 was used as the check variety.

Methodology:

The experiment was conducted at the Agricultural Research Station, Raikhali in the district of Rangamati during the summer seasons of 2006 and 2007. The climate of the area is tropical with high temperature. The total rainfall of 2007 was higher than that of 2006. The experimental field belongs to AEZ 29 with the piedmont plain soil having medium loamy to moderately fine texture. The soil was poor in organic matter and moderately acidic. Prior to planting, seeds were soaked in tap water for 24 hours for uniform and better germination. After complete emergence, thinning was done leaving one seedling in each hill. The harvesting of fruit was stared on 14 May in 2006 and 18 May in 2007, and was continued up to 28 June in 2006 and 30 June in 2007. Recommended cultural and plant protection measures were followed throughout the period of experiment. The data on plant height at 1^st flowering, number of branches per plant, number of leaves per plant, number of fruits per plant, length and diameter of fruit, individual fruit weight, and fruit yield per plant were recorded from 10 plants selected at random from the inner rows of the plots. Data on days to appearance of 1^st Yellow Vein Mosaic Virus affected plants and percentage of virus affected plants were also taken. The per plot yield from the harvest area of 5.4 m² (3.0 x 1.8 m) was recorded and the yield per hectare was estimated from the per plot yield data. The treatment means were separated by DMRT at 5% level of significance for interpretation of the results.

Achievement/Findings:

The okra variety Suriya produced the maximum fruit yield (19.29 t/ha) which was statistically similar to Sabuj Bangla. The variety Supriya planted at 50 x 30 cm spacing gave the highest yield of fruits per hectare, which was closely followed by Sabuj Bangla under the same spacing. All the varieties were affected by yellow vein mosaic virus except Sarash-2 and Supriya. Although BARI Dherosh-1 plants were severely infected with YVMV, the variety gave fruit yield of 15.84 to 17.66 tonnes pr hectare under 60 x 30 cm and 50 x 30 cm plant spacing respectively.Attempts of producing BARI Dherosh-1 plants free from YVMV might help improvement of the variety. Based on the findings of the present study the variety Supriya may be recommended for production in the hilly region of Bangladesh using 50 x 30 cm plant spacing.
