Abstract
Mushrooms have been known for ages for its nutritive value. Volvariella volvacea commonly
referred to as paddy straw mushroom due to its traditional cultivation on paddy straw substrate. The present
studies were carried out to investigate the possibility of growing paddy straw mushroom (Volvariella
volvacea) under Haryana conditions on locally available substrates. The physiological studies were done to
determine the optimum pH and temperature conditions for mycelial growth of V. volvacea under in vitro
conditions. It requires temperature of 30-35oC and pH 6-8 for optimum mycelial growth. Among different
media evaluated, potato maltose agar and malt extract agar supported better growth and Czapek Dox agar
supported the least growth of mycelium. Among different agro-residue extract media, wheat straw extract
agar was best medium and paddy straw extract agar medium supported the least mycelial growth under in
vitro conditions. The cellulolytic activity of V. volvacea was determined to assess its cellulose degrading
ability. All the three strains (VV-01, VV-02 and VV-11) of V. volvacea exhibited low cellulolytic activity.
Bajra grains were recorded most suited for spawn preparation. The spawn run and pin head formation was
earlier on paddy straw. Wheat straw was found to be most suitable substrate for cultivation in terms of
biological efficiency but paddy straw is better option by taking consideration of economics under Haryana
conditions. The protein content was 27.5 %.
