Abstract
Purpose The research aimed to study the efects of size reduction and composting duration of empty fruit bunches (EFB) on straw mushroom production, and to examine the doses of fertilizers commonly used among farmers. Methods The experiment was done in two stages. The frst stage was for identifying the optimum physical parameters of EFB, and the second stage focused on enhancing the performance of EFB chosen based on the fndings of the frst experiment. A randomized complete block design with 3×3 factorial arrangement in both stages of the study used the same approach. The frst stage had three levels of aggregate sizes factor (S) and three levels of composting duration factor (C) of EFB. The second stage had three levels of NPK factor (N) and three levels of organic fertilizer factor (O). Results Whole stalk EFB had the highest productivity of 2458.47±1015.23 g m−2. The supplementation of fertilizers increased the EFB decomposition rate and productivity to 2950.24±208.50 g m−2, and nutritive values (particularly for protein content of 41.00±3.79%). Averaged biological conversion efciency (BCE) was also improved from 3.61±1.22 to 6.56±0.46%. Conclusions EFB did not need to be cut into smaller pieces, and should not be composted for more than 8 days, because there was a tendency to decrease yield. Supplemental fertilizers increased the decomposition rates of EFB as well as the yield and nutritive values of straw mushroom. BCE can potentially be improved by increasing the dosages of fertilizers.
