Objectives: The current study investigated the effects of different environmental conditions on mushrooms morphology, moisture contents and yields to find out the most efficient way for indoor cultivation with maximum yield and morphology. Methods/Statistical Analysis: In this study, Pleurotus pulmonarius was cultivated in ambient indoor environment without humidifying and ventilation (System 1), indoor humidifying environment without ventilation (System 2) and indoor humidifying environment with ventilation (System 3). Findings: The highest humidity 90% was recorded both in System 2 and System 3 but the lowest temperature 26.50C was only recorded in System 3 whereas the lowest humidity 41% and highest temperature 320C was recorded in System 1. The highest individual weight (202g), numbers of fruitbodies (17), cap diameter (15cm), stalk height (15cm), outstanding (39%) moisture containing fruitbodies and bio-efficiency (73.6%) was recorded in System3 which was significantly higher than System 1 and System 2. In System 2, the individual weight (120g), numbers of fruitbodies (13), cap diameter (9cm), stalk height (11cm), outstanding (19.1%) moisture containing fruitbodies and bio-efficiency (44.1%) was recorded which is significantly higher than System 1 but lower than System 3. The strongest correlation of individual weight was found with temperature, humidity, numbers of fruitbodies and moisture contents where the numbers of fruitbodies and moisture contents also had correlation with temperature and humidity. Application/Improvement: This study provides an evidence of significant differences among the cultivation systems where the morphology, quality and yields were started to increase as System 1˂ System 2˂ System 3. Therefore, the design of System 3 is an effective model and method to optimize and control the indoor environmental factors which is an alternative way for indoor mushroom cultivation with higher yield.
