I want to store my rabi onion at home instead of selling at crash prices. How should the storage structure be built?
How do I build a low cost ventilated onion (pyaaz) storage chawl on my farm?

The whole idea of an onion chawl is cross ventilation so the bulbs stay dry and cool. Build it in an open, airy spot, raise the floor off the ground, and make the side walls slatted with gaps so air passes through the stack from both sides, not solid walls that trap heat and moisture. Keep the stack width limited so air reaches the centre, usually a bottom and top ventilation gap is provided so air moves up through the pile. Use a sloping roof that keeps out rain but allows a ridge gap for hot air to escape. Store only cured, dry, tight necked bulbs, inspect regularly and remove rotting ones. Government horticulture schemes sometimes give subsidy for onion storage structures, so check with your district horticulture office and KVK for current designs and assistance before building.

Orientation helped me a lot. I aligned the length of the chawl so the open slatted sides face the prevailing wind, and the natural breeze keeps the stack cool without any fans. Putting it under a tree shade or near a wall that blocks the wind defeats the purpose.

I built mine on a low budget using locally available wooden poles and bamboo for the slatted sides and a tin sheet roof with a ridge gap. Keeping the stack only about a metre and a half wide meant air reached the centre. The cost was far less than the value I saved by not selling at the crash.

Do apply for the horticulture subsidy before you build, not after. A neighbour built first and then found the scheme needed a sanctioned design and prior approval, so he missed the assistance. Check the current pattern with your district horticulture office first.

I made the bottom of the chawl a slatted floor raised on a low platform so air comes up through the stack from underneath as well as the sides. The bottom layer used to sweat and rot when it sat on a solid floor. The under floor gap stopped that.

Inspect the stack regularly and pull out any rotting bulb as soon as you spot it. I learnt that one soft bulb left in place spoils the ones around it and the rot creeps through the heap. A walk through every week or two to remove the bad ones keeps the loss down.

Only fill the chawl with properly cured, tight necked bulbs. The first year I stacked some half cured thick necked bulbs along with the good ones and they rotted and started the spoilage. Now I sort hard before filling and the same structure keeps the onions far better.
