Button Mushroom Cultivation Guide (60 Days)

Frequently asked questions

How long does one button mushroom crop cycle take?

A commercial button mushroom (Agaricus bisporus) cycle runs about 60 days end to end: spawn run 14-16 days at 24-25°C, casing 7 days, pinning 5-7 days at 16-18°C, then 3 flushes of picking spread over roughly 30-35 days.

What temperature and humidity do button mushrooms need?

Spawn run needs 24-25°C air with 90-95% RH and high CO2. Cropping needs 16-18°C air, 85-90% RH and CO2 below 1,000 ppm, which in Indian conditions requires a climate-controlled PUF-panel room with refrigeration and fresh-air exchange.

How much yield does button mushroom farming give per tonne of compost?

Well-prepared Phase-II compost yields roughly 18-25% biological efficiency, i.e. about 180-250 kg of mushrooms per tonne of compost across three flushes. A 1,000-bag (10 kg bags) room typically produces around 2,000 kg per cycle.

What compost is used for button mushroom cultivation?

Wheat straw based synthetic compost with chicken manure, wheat bran, urea, gypsum and DAP, prepared through Phase-I outdoor composting (14-16 days) and Phase-II pasteurisation and conditioning (6-8 days) at 58-60°C, followed by spawning at 0.5-0.75% of compost weight.

How much does it cost to start button mushroom cultivation in India?

A 2-room climate-controlled starter unit typically starts around Rs 16-20 lakh, a 6-room commercial farm around Rs 45-55 lakh, excluding GST at 18% and transport. Land, civil work and boundary are client scope.
