Studies on yield attributes of new Pleurotus djamor isolate KKM 1
358
Abstract
The experiments were carried out to evaluate the cropping duration and biological efficiency of new Pleurotus djamor isolate KKM 1 compared with commercially cultivated mushroom varieties viz., P. djamor var.MDU-1, P. florida and P. eous var. APK1.Among the tested Pleurotus spp., P. djamor isolate KKM 1 produced primordia and matured basidiocarp in shortest period after spawning i.e at 10 days and 14 days respectively. Whereas, other tested Pleurotus spp. produced mature basidiocarp at 16-21 days after spawning. The cropping duration of P. djamor isolate KKM 1 was 29 days. Whereas, other Pleurotus spp. completed cropping cycle in 40-48 days. With regards to biological efficiency, P. djamor isolate KKM 1 showed the maximum biological efficiency of 105% during winter and 87% during summer followed by P florida which showed 91.43% biological efficiency during winter and 80 % biological efficiency during summer. Thus, the present study clearly indicates that P. djamor isolate KKM1 is a short crop duration isolate with higher biological efficiency.
