Crop Adaption

a. Temperature

• Warm and humid climate desirable with temperature 24-370 C.
• < 200C and >400C restricts plant growth.

b. Light

• Typical short-day plant thus flowers at the approach of Aug-Sept.
• Critical photoperiod is 12.5 hours, above which flowering is retarded.
• Long photoperiod induces vegetative growth.
• olitorius more responsive to short photoperiod than C. capsularis.

c. Rainfall

• 1500 mm rain per annum with 250 mm from March to May is ideal.
• Younger stages sensitive to water stagnation.
• In later stages, C. capsularies tolerate waterlogging better.

d. Relative Humidity (RH)

• Permissible diurnal variation in RH for better growth and fiber quality is 60-90%.

e. Edaphic requirements

• The new gray alluvial soil of good depth, well aerated, with silt deposition from annual floods, is best for jute.
• However, jute is grown widely in sandy loams and clay loams.
• Desirable pH 6-7.5.
• It is generalized that loam for capsularis and sandy for olitorius is most suitable.
