Effect of Casing Mixtures along with Turmeric Powder on the Growth Parameters and Yield of White Button Mushroom [Agaricus bisporus (Lange) Imbach]

Abstract

Protein is one of the nutrients that is included in balance diet for proper growth and development of humankind. The amount of food that is needed for human consumption is insufficient. Agaricus bisporus (Lange) Imbach commonly known as white button mushroom, is the most widely accepted food globally with nutritional and medicinal properties. The present experiment was conducted during the Rabi season 2023 at Mushroom crop room, Department of Plant Pathology, SHUATS, Prayagraj, Uttar Pradesh to evaluate the effect of Turmeric powder at different concentrations (0.5%, 1%, 1.5%, 2% and 2.5%) incorporated into three different casing mixture viz., FYM + Cocopeat + Sawdust (1:1:1) with an objective to monitor the growth and yield aspects of white button mushroom. Turmeric at concentration 2% shows significant increase of weight of fruiting bodies, enhances stalk length, stalk diameter and pileus diameter. These results were also observed at 2.5% concentration but it also inhibited the growth of mold fungus as well as A. bisporus. Among all treatments used in the study, the results revealed that minimum average time taken for completion of spawn run (15.28 days) and pinhead initiation (17.29 days) as well as maximum pileus diameter (4.87 cm), stalk length (3.32 cm), stalk diameter (2.36 cm), yield (583.33 g) and biological efficiency (13.56) highest recorded in T4 [FYM + Cocopeat + Sawdust (1:1:1) + Turmeric powder @ 2%.
