KHARIF CROPS
COTTON
India is one of the world’s largest cotton producers and exporters.
A key commercial crop, cotton is grown in around 11-12 million ha in the Kharif season.
Cotton supports millions of farmers and drives allied activities like ginning, pressing, and transport.
Why Your Cotton Needs Phosphorus?
Strong root & early
crop establishment
Phosphorus promotes deep root development, helping cotton plants establish quickly, tolerate early stress, and use soil nutrients more efficiently.
Flowering, boll
formation & retention
It supports energy transfer (ATP), which is critical during flowering, leading to better boll setting, reduced shedding, and improved crop uniformity.
Yield & fibre quality
improvement
Adequate phosphorus enhances boll size, seed development, and ultimately improves yield as well as fibre strength and quality.
