Effect of Culture Materials for Growth and Productio of Hed Cone Noi (Coprinopsis radiate)

Abstract

The The objective of this research was to study growth and production of Coprinopsis radiata (Hed Cone Noi) in culture materials, rice straw, bagasse, and coir. The experiments were performed in 10 replicates/group which consisted of 5 groups, 100% rice straw (control), 100% bagasse, 100% coir, 1:1 rice straw:bagasse, and 1:1 rice straw:coir group. The culture was done in 20 days. The results showed that 100% rice straw group had the highest production of Coprinopsis radiata, weight 50.05 ± 0.47 g, quantity 43.33 ± 1.53 mushrooms, biological efficiency 8.86 ± 0.36%, cap wide 0.96 ± 0.04 cm, cap length 1.69 ± 0.03 cm, stem wide 0.66 ± 0.02 cm, and stem length 1.97 ± 0.02 cm. The 1:1 rice straw:bagasse group was second place of mushroom production, weight 48.11 ± 1.10 g, quantity 41.00 ± 1.00 mushrooms, biological efficiency 7.21 ± 0.10%, cap wide 0.91 ± 0.01 cm, cap length 1.53 ± 0.02 cm, stem wide 0.56 ± 0.03 cm, and stem length 1.86 ± 0.03 cm. In conclusion, the rice straw showed the best production result. The use of 1:1 rice straw:bagasse formula could provide the mushroom production close to the rice straw alone. This 1:1 rice straw:bagasse formula would help reduce the shortage of rice straw from rice harvesting of farmers by using other local materials for culture of Coprinopsis radiata.
