Effect of Abiotic Factors on Oyster Mushroom Production (Pleurotus Species)

This study aims to determine the factors of production that affect oyster mushroom farming and analyze the level of efficiency of the use of production factors on oyster mushroom farming in UPT Agriculture Area Sukaraja. The method used in this research is survey with explorative descriptive approach. The data used are primary data secondary data obtained through interviews, questionnaires and literature study. The results analsis show a total coefficient value of 2.143. This value indicates the scale of oyster mushroom production is in phase I or increasing return to scale (IRS). The value of the coefficient of determination (R2) is 92.3 percent means that 92.3 percent of oyster mushroom production can be explained by variable use of production factors, while the remaining 7.7 percent is influenced by other variables besides the use of production factors not included in the model. The use of production factors that significantly influence the variation of oyster mushroom production are land and sawdust. While seeds, bran labor polybag, lime, paralon ring, rubbe and paper have no significant effect.

Summary An experiment has been conducted to study the effect of sludge concentration, waste of paper industry using raw material of recycled paper, as media on oyster mushroom production and quality. Twelve treatment tested are combination of two oyster mushroom strains are oyster mushroom of Bogor (JTB) and oyster mushroom of Taiwan (JTT), three media composition (sawdust, sludge, and sawdust+ sludge (50/50, v/v), and two levels of supplement addition (with rice bran+gypsum+ lime and without) with 10 replications. The production of the mushroom was conducted in bag log capacity of 1 kg fresh weight (water content 50%). The result showed that sludge can be used as mixture of oyster mushroom production with the composition 50:50 v/v of sawdust and sludge. Since the higher number of contamination, addition of supplement reduce oyster mushroom production as well as biological efficiency, but increased protein content of fruiting body. The content of Cd, and Pb were below the permissible limits, Cu was higher than the limits but still in the range. The Fe content of mushroom fruit body was higher both in sawdust (147.92 – 149.56 ppm) and sawdust+sludge (295.82 – 335.12 ppm) as media. However, the uptake of Fe of JTT was less (49.08-59.64 ppm) compared to that of JTB (147.92-335.12 ppm).Ringkasan Penelitian dilakukan untuk mempelajari pengaruh konsentrasi sludge limbah pabrik kertas berbahan baku karton bekas sebagai medium terhadap produksi dan kualitas jamur tiram. Dua belas perlakuan yang diuji merupakan kombinasi dua galur jamur tiram, yaitu Jamur Tiram Bogor (JTB) dan Jamur Tiram Taiwan (JTT), tiga jenis komposisi medium (serbuk gergaji, sludge, dan sludge+ serbuk gergaji), dan dua tingkat suplemen (dengan dan tanpa) yang diulang 10 kali untuk masing-masing perlakuan. Produksi jamur tiram dilakukan menggunakan bag log berkapasitas 1 kg basah (kadar air 50%). Hasil percobaan menunjukkan bahwa sludge dapat digunakan sebagai campuran serbuk gergaji dalam produksi jamur tiram dengan per-bandingan 50:50 (v/v). Pemberian suplemen menurunkan produksi jamur tiram demikian pula efisiensi biologi namun meningkatkan kadar protein tubuh buah. Di dalam tubuh buah JTB, kandungan logam Cd, dan Pb berada di bawah batas yang diijinkan, sedangkan kandungan Cu di atas ambang walaupun masih dalam kisaran. Kandungan Fe dalam tubuh buah jamur relatif tinggi baik yang ditumbuhkan pada serbuk gergaji sebagai medium standar (147,92 - 149,56 ppm) maupun yang ditumbuhkan pada medium campuran sludge+serbuk gergaji (295,82 - 335,12 ppm). Serapan Fe tubuh buah JTT jauh lebih rendah (49,08- 59,64 ppm) dibandingkan dengan serapan Fe JTB (147,92-335,12 ppm).

The Impact

This study based on cross sectional data of 94 oyster mushroom farms in Quang Tri province to measure their technical efficiencies at farm level and identify the impact of attending training course variable on it by using two stage Bootstrapped Data Envelopment Analysis. The empirical results confirm that attending training course is an important factor impact on technical efficiency of oyster mushroom farm in study area. The farms used to attend a relevant training course were more efficient than farms did not. Moreover, it also shows that gender of the farmer, gender of the farmer, source of irrigation water, duration of oyster mushroom production and number of oyster mushroom crops cultivated on this current farm also had significantly relationship with technical efficiency. Comparing to the best practice farms in this sample, the oyster mushroom farms in study area should use fewer inputs to produce the current level of output to be efficient. Especially, farmers should attend the relevant training course and local authority should organize more training course to improve current level of efficiency of those farms. Moreover, the impacts of gender of the farmer, source of irrigation water, duration of production and number of crops should also be included in the content of those up-coming training courses.

Abstract Pleurotus mushrooms are among the most cultivated fungi in the world and are highly valuable for food, medicine, and biotechnology industries. Furthermore, Pleurotus species are carnivorous fungi; they can rapidly paralyze and kill nematodes when nutrient-deprived. The predator–prey interactions between Pleurotus and nematodes are still widely unexplored. Moreover, the molecular mechanisms and the genes involved in the carnivorous behavior of Pleurotus mushrooms remain a mystery. We are attempting to understand the interactions between Pleurotus mushrooms and their nematode prey through genetic and genomic analyses. Two single spores (ss2 and ss5) isolated from a fruiting body of Pleurotus pulmonarius exhibited significant differences in growth and toxicity against nematodes. Thus, using PacBio long reads, we assembled and annotated two high-quality genomes for these two isolates of P. pulmonarius. Each of these assemblies contains 23 scaffolds, including 6 (ss2) and 8 (ss5) telomere-to-telomere scaffolds, and they are among the most complete assembled genomes of the Pleurotus species. Comparative analyses identified the genomic differences between the two P. pulmonarius strains. In sum, this work provides a genomic resource that will be invaluable for better understanding the Italian oyster mushroom P. pulmonarius.
