Abstract

This study aimed to use straw of Sesbania sesban (Egyptian pea) in the formulation of a compost for producing Agaricus bisporus F599 and C9 by using three casing layers namely Topterra, Kekkila, and Local. The highest total yield was 1031 g/bag on B compost with Topterra casing layer for A. bisporus F599, while A. bisporus C9 cultivated on compost-A with Local casing layer exhibited the lowest yield of 684 g/bag. The best biological efficiency was 45.80% for A. bisporus F599 on compost-B with Topterra. Furthermore, A. bisporus C9 cultivated on compost-A with Local showed the lowest biological efficiency of 30.39%. A. bisporus F599 recorded higher average fruit weights of 35.31 and 34.00 g on compost-B in casings with Local and Kekkila, respectively. A. bisporus C9 on compost-B with Topterra recorded the largest number of fruit at 35.0 fruit/bag. Finally, a compost of S. sesban (compost-B) is suitable for cultivating this mushroom, especially with Topterra.
