Effectiveness of arbuscular mycorrhiza fungi propagules to growth of mustard plant (Brassica juncea L.) under net house treatment

The purpose of this study was to determine the growth of mustard plant (Brassica juncea L.) responses to arbuscular mycorrhiza fungi under net house treatment. This research was conducted in net house of SindangKasih village, District of West Ranomeeto, South Konawe, and Laboratory of the Faculty Forestry and Environmental Science Halu Oleo University Kendari, Indonesia. This study used a Completely Randomized Design (CRD), which consists of 5 treatments i.e.: with out of mycorrhiza fungi propagules (M0), mycorrhiza fungi propagules as 25 g per polybag (M1), mycorrhiza fungi propagules as 50 g per polybag (M2), mycorrhiza fungi propagules as 75 g per polybag (M3), mycorrhiza fungi propagules as 100 g per polybag (M4). The variables observed were plant height, leaf number, total leaf area, specific leaves area and percentage of mycorrhiza fungi infection on rooting of mustard plant. The result of the research showed that application of the mycorrhiza fungi propagules at doses of 75 g per polybag given the highest of total leaves area as such as 1800.8 cm2, application the mycorrhiza fungi propagules at doses of 100 g per polybag given the highest specific of leaves area as such as 113.7 cm2, and application the mycorrhiza fungi at doses 25 g per polybag given the highest of percentage of mycorrhiza fungi infection to rooting of mustard plant as such as 14.90%.
