Soil
It is adaptable to a wide range of soils from sandy loam to clayey loam.
Season
Planting can be done during June - August and February

Preparation of Okra field
Sowing operation
Seed rate
Varieties : 8.0 kg / ha
Hybrids : 2.5 kg / ha
Seed treatment
Seed treatment with Tricoderma viride @ 4 g/kg or Pseudomonas fluorescens @ 10 g/ kg of seeds and again with 400 g of Azospirillum using starch as adhesive and dried in shade for 20 minutes. Sow three seeds per hill at 30 cm apart and then thin to 2 plants per hill after 10 days.
Sowing
Sow three seeds per hill at 30 cm apart and then thin to 2 plants per hill after 10 days.
Spacing
Seeds are sown at a spacing of 45 x 30 cm.

Irrigation
Irrigation is done at weekly intervals.
Application of Fertilizers
Apply Azospirillum and Phosphobacteria each at 2 kg/ha mixed with 100 kg of FYM before sowing.
Varieties
Basal dose FYM @ 25 t/ha, N @ 20 kg, P @ 50 kg and K @ 30 kg/ha as basal and 20 kg N/ha at 30 days after sowing.
Hybrids
Basal dose FYM @ 40 t / ha, N @ 100 kg, P @ 100 kg and K @ 100 kg/ha as basal and 100 kg N / ha 30 at days after sowing.
Foliar nutrition
1 % urea (10 g/l) + muriate of potash (10 g/l) on 30 and 45 days after planting. For hybrids, foliar application of water soluble fertilizer 19-19-19 three times @ 0.5% (5 g/l) at 10 days interval from 30 days after planting
