Tropical and subtropical vegetables (2+1)

Climate and soil

• The crop is basically adapted to tropical climate and vigorous warm humid weather for best growth and production. It is susceptible to drought and low night temperatures. For seed germination optimum soil moisture and a temperature range between 25 and 35oC is required, with fast germination observed at 35oC. Seeds fail to germinate below 17oC. At temperature above 42oC flower buds in most of the cultivars may desiccate and drop causing yield losses. The optimum temperature range for growth is 20-30oC. Sunlight is equally important for bhendi crop. A 50 % reduction in sunlight during first three weeks after sowing has adverse effect on yield.
• It can be grown in all kinds of soils ranging from sandy loam to clay. However, high yields can be obtained in loose friable, well manured loamy soils having better drainage. The soil optimum pH for okra ranges from 6-6.8.
