Its net profit stood at Rs 28.31 crore in the year-ago period, the company said in a regulatory filing.
Total income fell to Rs 938.21 crore in the second quarter of this fiscal, from Rs 1,095.03 crore in the corresponding period of the previous year.
The company witnessed marginal growth in chemical business, but showed subdued performance in fertiliser.
The combined negative impact in the fertiliser sector emerging out of the delayed monsoons, inventory build-up from the earlier quarter and sudden price cuts impacted the quarterly performance, it said.
