ABSTRACT
Oyster mushrooms are rich in protein and highly nutritious. The study was conducted to determine the yield performance of Oyster mushroom using different agricultural wastes and their combinations as substrates, and to identify the best substrate for mushroom culture. The different agricultural wastes used were rice straws (RS), corn stalks (CS), banana leaves (BL), and their combinations. The experiment was laid out in Completely Randomized Design (CRD), with six treatments and in three replications with a total of 18 experimental units. Polypropylene bags with different substrates were arranged in the 4m x 5m mushroom house located at Bliss, Buug, Zamboanga Sibugay. Random numbers for treatment assignment were ranked in ascending orders. The treatments were: T1 – 98% RS, T2 – 98% CS, T3 – 98% BL, T4 – 49% rice RS + 49% CS, T5 – 49% RS + 49% BL, and T6 – 49% CS + 49% BL. All treatments were added with 1% agricultural lime, and 1% rice bran to obtain the 100% dry weight of formulated substrate. The mushrooms were harvested in three flushing periods, which started eighteen days after seeding. Yield parameters were gathered, and the total yield obtained per treatment were collated and subjected to statistical analysis using the STAR software. ANOVA revealed highly significant differences among treatment means in terms of number, weight, and average weight of mushroom raised in different culture media. Tukey’s HSD test revealed that mushroom cultured in 98% RS (T1) had the highest yield compared to the other treatments. This may also suggest that substrate containing 98% RS produced higher yield compared to RS mixed with other agricultural wastes. The results further indicate that pure substrates produce heavier mushrooms than when in combined state. Further study be conducted to validate the results, particularly in areas where rice straws (RS) are unavailable.
