Abstract/ Executive Summary:

The effects of different plant spacing, namely, 80 x 40 cm, 80 x 20 cm and 80 x 10 cm and different picking intervals namely, 1,3 and 5 days on the yield and yield components of okra cv. Pusa Sawani were studied at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh. The fresh weight of plant, number of fruits per plant and weight of fruit per plant increased significantly with and increase in plant spacing. However, the yield per hectare decreased with the increasing plant spacing. Highest yield (7.15 t/ha) was obtained in close spacing (80 x 10 cm) while the yield was minimum (3.23 t/ha) in wide spacing (80 x 40 cm). Picking interval had no effect on the yield per hactare, but the fruit length was influenced significantly. Longer fruits of the average length of 12.31 cm was obtained at 5 days picking interval and a minimum length of 9.39 cm was obtained by picking at 1 day interval. There was no interaction between the effects of spacing and picking interval on the yield and the other yield components studied.

Start Date: 00-02-1988

End Date: 00-05-1988

Program Area: Crop-Soil-Water Management

Commodity: Okra

Objectives:

To studying the effects of plant spacing and picking interval on the growth and yield of okra.

Methodology:

The experiment was carried out at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh, The treatments of the experiment consisted of 3 levels of plant spacing 40, 20 and 10 cm with constant row spacing of 80 cm and 3 levels of picking interval (1,3 and 5 days). The spacing and the corresponding plant densities were as follows: The seeds of the cultivar, Pusa Sawani were sown at a depth of 2 cm on 20 February, 1988. The experiment was laid down in a completely randomized block design with three replications. The size of unit plot was 4 x 2m. The field plot was situated in a sandy loam soil with an average pH of 6.6. A basal dressing of cowdung manure and triple supper phosphate at the rate of 10 tons and 100 kg/ha respectively, were applied during land preparation. Urea and muriate of potash each at the rate of 150 kg/ha were applied in three equal side dressings at a fortnight interval starting two weeks after sowing. Harvesting commenced on 4 April and continued upto 8 May, 1988. The pods were harvested at a minimum length of 7 cm. Insecticide was applied everyone week. Irrigation, weeding and other intercultural operations were done as and when necessary.

Achievement/Findings:

The above result indicated that okra cv. Pusa Sawani grown at close spacing of 80 x 10 cm would be able to give consistently higher yield and possibly with a better quality when pickings are done at 3 day interval.
