Abstract/ Executive Summary:

An experiment was conducted at the Hill Agricultural Research Station, Khagrachari from June to November 2005 to find out the effect of hill elevation (0-5 m, 5-10 m, 10-15 m and 15-20 m) and de-topping (Control 3, 6 and 9 leaf) on the yield and yield components of okra in hill slope. Plants grown on 0-5 m hill elevation with 3 leaf stage de-topping produced the most satisfactory yield (17.07 t/ha) and the lowest yield (8.28 t/ha) was obtained from 15-20 m hill elevation with 9 leaf stage de-topping. The highest gross return (Tk. 1,71,200) and net return (Tk. 1,21,860) and BCR (3.47) were also found from 0-5 m hill elevation with 3 leaf stage de-topping treatment combination

Keywords: De-topping, okra, yield. De-topping

Location: Hill Agricultural Research Station, Khagrachari

Start Date: 01-06-2004

End Date: 31-12-2004

Program Area: Crop-Soil-Water Management

Commodity: Okra

Objectives:

To find out the effect of hill elevation and plant de-topping on the growth and yield of okra in hill slope condition during rainy reason.

Methodology:

The experiment was conducted at the Hill Agricultural Research Station, Khagrachari from June to November 2005. The treatments of the experiment were 4 hill elevation (0-5 m, 5-10 m, 10-15 m and 15-20 m) and 4 plant de-topping (Control, 3, 6 and 9 leaf). Thus there were 48 units (4×4×3) in total. The experiment was laid out in split-plot design with three replications keeping hill elevation in main plot and 4 levels of de-topping treatment was allocated in sub-plots. The unit plot size was 3.0 × 2.4 m. The plot and blocks were separated by 0.5 m and 1.0 m respectively. Seeds of okra were sown on July 03, 2005 at spacing 60×40 cm. Fertilizers were used at the rate of 150, 100 and 150 urea, TSP and MP t/ha respectively. Cowdung was used 10 t/ha during land preparation. Intercultural operations were done as and when necessary. Harvesting of fruits started 20th August and continued up to 30 October 2005. Data of yield contributing characters were recorded from ten selected plants but yield was recorded on plot basis. Collected data were subjected to statistically analysis by F-test and the difference between the treatments means were judged by Duncan’s Multiple Range Test (DMRT).

Budget: 15000/-

Total Budget (Tk.) : 15000/-

Achievement/Findings:

In the combination, plants grown on 0-5 m hill elevation with 3 leaf stage de-topping produced the most satisfactory yield (17.07 t/ha) and the lowest yield (8.28 t/ha) was obtained from 15-20 m hill elevation with 9 leaf stage de-topping.The production cost was lowest (Tk. 46,320) in case of 0-5 m hill elevation with control treatment where no de-topping was done and the highest cost of production (Tk. 49,300) was on 10-15 m hill elevation with 3 leaf stage de-topping. The highest gross return (Tk. 1,71,200) and net return (Tk. 1,21,860) and BCR (3.47) were also found from same treatment.
