Button mushroom is grown in winter. The most suitable temperature for the spread of the mycelium is 24-25°C, while 16-18°C is essential for the formation of fruit bodies.Higher temperature is harmful and low temperature retards the development of both mushroom mycelium and fruit bodies.
he cultivated mushroom is grown on special composts, which are of the following two types, synthetic and natural.
Composting yard
The compost should be prepared on well cleaned concrete or pucca floor, which should be at a higher level so that the run-off water does not collect near the heap.Composting is usually done in the open, but it has to be protected from rain by covering it with polythene sheet. It can also be done in a shed with open sides or a large room to shelter it from rain.
1. Synthetic compost
The following ingredients are required for 15-16 trays of size 100cmx50cmx15cm:-
Wheat straw (chopped 8-20cm long)-250kg, Wheat/rice bran-20kg, Ammonium sulphate/calcium ammonium nitrate-3 kg, Urea-3kg, Gypsum-20kg
The straw is uniformly spread over the compo sting yard in a thin layer and wetted thoroughly by sprinkling water. All ingredients such as wheat bran, fertilizers, etc. except gypsum, are mixed thoroughly in the wetted straw, which is finally heaped into a pile. The pile, 1m high, 1m wide and length adjustable, can be made with hand or stack mould. The straw should be firmly but not compactly compressed into the mould.
It is essential to open the entire pile and remake it a number of times according to the following schedule:
Mixing of material and making pile - 0 day
1st turning - 4th day
2nd turning - 8th day
3rd turning - 12th day, add 10 kg gypsum
4th turning - 16th day, add 10 kg gypsum
Final turning - 20th day,spray 10 ml malathion in 5 litre water (any other available pesticide like DOT, BHC, lindane can also be used)
At each turning water should be sprinkled to make up the loss of water due to evaporation. If it is desired to add molasses, then 10 kg molasses diluted 20 times with water should be poured over the straw mixture during the first turning. Sixty kg chicken manure, if available, can also be added at the time of start of pile.
Cropping and HalVesting
The first flush of the pin heads become visible 15-20 days after casing or 35-40 days after spawning. Small white buttons develop 5-6 days after pin head stage. The right stage of harvest is when the caps are still tight over the short stem. In case the buttons are allowed to mature further, the membrane below the cap will rupture and the cap will open up in umbrella-like shape. Such mushrooms are considered to be inferior. Harvesting is done by holding the cap with forefingers slightly pressed against the soil and twisting it off. The soil particles and mycelial threads clinging to the base of the stalk are chopped off. Mushroom can also be harvested by cutting off with a sharp knife at soil level.
Yield
The average yield of 3-4 kg per tray is considered normal. However, if compost is carefully prepared, spawn is reliable and temperature is favourable, then a yield of 5-6 kg per tray is possible. Partial or complete failure may also happen due to negligence.
Storage
The mushrooms are best consumed fresh. Storage in refrigerator for a few days is possible if they are placed between moist paper towel.
