EFFECT OF COMPOST AND GROWING STRUCTURES ON GROWTH AND YIELD OF BUTTON MUSHROOM (Agaricusbisporus(Lange) Imbach)

Abstract

Present experiment was conducted during 2017-18 in the Department of Plant Pathology, CoA, IGKV, Raipur, Chhattisgarh to know the effect of different straw prepared compost [Wheat straw and Wheat straw + Paddy straw (1:1)] and growing structure (Growing room and Ecofrost cold storage) on growth and yield of button mushroom. The results obtained that on the different straw prepared compost, spawn run was found significantly fastest (13.30 days) in wheat straw while, the days required for pinhead initiation was less (15.60 days) in combination of wheat straw + paddy straw. The yield attributing characters did not differed significantly and the number of fruiting bodies varied from 23.60 - 31.00. The fresh yield of button mushroom on different straw prepared compost, significantly maximum (560g) with 11.2 % biological efficiency was recorded in combination of wheat straw + paddy straw. Under the different growing structure the quickest (16.80 days) pinhead initiation was recorded in Growing room and the stalk length, stalk diameter did not found significant and the pileus diameter was found significant with growing structure. The number of fruiting bodies varied from 44.60 - 32.80. Thefresh yield of button mushroom was not differed significantly under the different growing structure and ranges from 559 – 662g with 11.18 – 13.24 % biological efficiency.

Keywords: Button mushroom, compost, straw and growing structure.
