Deficiency guide
Spot it, fix it
General symptoms that apply across crops. Confirm with a soil or leaf test before treating.2
Growing points develop abnormally; the tips become stunted and die, and flowers and fruits may abort.
Upper leaves show interveinal chlorosis, eventually whitening. Leaves may be small and distorted, in a rosette form.
Growth is slow and stunted, and older leaves turn purple, especially on the underside.

How do I convert a per-katha dose to bigha or acre?
