Almost all the psyllium husk used in the world comes from a handful of dry districts in western India, and it leaves the country as an export earner rather than as food. That makes isabgol unusual in this library twice over. It is a crop that asks for very little water, which is exactly why it suits land where nothing thirsty will grow, and it is a crop whose price is set on the other side of the world rather than in the local mandi. For a farmer on light sandy ground with a short cool season and three or four irrigations available, it is one of the few genuinely high-value options. The whole crop turns, however, on one thing that no amount of good farming can control: it must be dry when you harvest it.
If you see: A field sown carefully where almost nothing comes up.
It likely means: Nearly always sown too deep. This seed is very small and has no strength to push up from depth.
Do this: Sow no more than about half a centimetre deep, which is barely covered.
If you see: Rain or heavy dew on a ripe crop, and seed that has gone dull, stained or sprouted.
It likely means: The weather turned before the crop was in. This is the single biggest risk in isabgol and it is largely outside your control.
Do this: Sow at the start of the cool season so the crop matures well before the weather can break.
If you see: Seed lying on the ground under the crop and a thin harvest from a field that looked full.
It likely means: It was cut too dry, or in the wind, or handled roughly. The ripe spike lets go of its seed very easily.
Do this: Cut in the early morning while dew is still on the crop, since the damp holds the seed in.
If you see: A short thin crop with weeds standing above it.
It likely means: It was not weeded early. Isabgol is a small low plant and it cannot compete with anything.
Do this: Clear the land thoroughly before sowing rather than planning to weed afterwards.
If you see: Pale distorted leaves with a greyish growth underneath, spreading after cloudy damp weather.
It likely means: Downy mildew. It follows exactly the weather that also threatens your harvest, so it often arrives at the worst moment.
Do this: Do not irrigate heavily during a cloudy spell.
If you see: A buyer marking the lot down for grit, dust or weed seed in the sample.
It likely means: The crop was threshed or stacked on bare soil, or not winnowed properly.
Do this: Stack and thresh on a clean swept floor or on sheets, never directly on bare soil.
Growing the crop is only part of the job. The last part is knowing what a normal harvest looks like where you are, and knowing what your isabgol is worth before you agree a price with anybody.
If you forget every other page of this guide, keep these lines. They are the whole crop, in order, short enough to carry in your head.
