Page "Psyllium" Paragraph 14

P. ovata is a 119-to 130-day crop that responds well to cool, dry weather.

In India, P. ovata is cultivated mainly in North Gujarat as a " Rabi " or post – rainy season crop ( October to March ).

During this season, which follows the monsoons, average temperatures are in the range of, and moisture is deficient.

Isabgol ( P. ovata ), which has a moderate water requirement, is given 5 to 6 light irrigations.

A very important environmental requirement of this crop is clear, sunny and dry weather preceding harvest.

High night temperature and cloudy wet weather close to harvest have a large negative impact on yield.

Rainfall on the mature crop may result in shattering and therefore major field losses.
