Post composting supplementation in Agaricus bisporus compost
 Technique for post composting supplementation of prepared A. bisporus compost under seasonal growing / controlled conditions have been perfected at this centre. Cotton seed meal, cotton seed cake, soybean meal, defatted soybean cake can be employed as supplements. First coarsely grind the supplements and treat them with 5000 ppm of formaldehyde and cover the supplements with polythene sheet. Leave as such for 24 hours for sterilization and denaturing of the supplements. Treated supplement can be added in the compost at the time of spawning @ 1% fresh wt of the compost. However supplementation at casing gives better results. In this case, required quantity of supplement (1%) is thoroughly mixed in the properly colonized compost just before casing and casing applied as usual.  Increase in yield due to supplementation at this stage with cottonseed meal or soybean meal is over-whelming (15-20% increase) whether tried on LMC or on short method compost.
