Abstract/ Executive Summary:

Three okra cultivars were tested in the field at three different plant densities. The yield per unit area increased with increase in plant density. With the increase in plant density from 4 to 8 and 15 plants /m² the average yield of green pods increased by about 29 and 92 % respectively. The cultivar Pusa-Do-Moushurni was the highest yielder. which yielded about 12. 20 and 27 tons of green pods per hectare at the density of 4. 8 and 15 plants/m²respectively.

Program Area: Crop-Soil-Water Management

Commodity: Okra

Objectives:

To investigate the yield ability of three exotic cultivars of okra under different plant densities.

Methodology:

The yield ability of three exotic cultivars of okra, namely, Pusa.Do-Moushumi (India), Penta-Green (Japan) and Clemson Spineless (Holland) were studied at the Horticulture Farm at the Bangladesh Agricultural University, Mymensingh. The different plant densities used in the experiment and the respective plant spacing . The three cultivars were planted at each of the three plant densities in the randomized complete block design. The nine treatment combinations replicated three times gave a total of 27 unit-plots. Each unit-plot consisted at a bed 3 m long and 2 m wide. The field plot was situated on a sandy loam soil with an average pH of 6. 6. The basal dressing of cowd ung manure and triple super phosphate at the rates of 9 t/ha and 92 kg/ha respectively were applied during land preparation. The seeds were sown on March 25, 1981 at a depth of about 1.5 em. Three equal side-dressings of urea and muriate of potash at the rates of 27 and 23 kg/ha respectively were applied at a fortnight interval, starting two weeks after sowing. Plant protection consisted of fortnightly sprays of Diazinon. Irrigation, weeding and all other intercultural operations were done as and when necessary. Harvesting commenced on may 16 and continued at an interval of 3 days upto June 26, 1981
