CHARACTERIZATION AND IMPACT OF MYCORRHIZA FUNGI ISOLATED FROM WEED PLANTS ON THE GROWTH AND YIELD OF MUSTARD PLANT (Brassica juncea L.)

Present study was aim to determined the impact of mycorrhiza fungi isolated from grasses weed on the growth and yield of mustard in Ultisols. Study was conducted in net house located in Sindang Kasih Village, Dictrict West Ranomeeto; Regency South Konawe Province of Southeast Sulawesi in the month of June to September 2014. Mycorrhiza fungi infection observated on plants root done in the Laboratory of the Faculty of Forestry and Environmental Science, Halu Oleo University, Kendari, Indonesia. Study was conducted in completely randomized block design (CRBD) with five treatments, each treatment was replicated with 5 replications. The variables observed for results were characteristic of mycorrhiza fungi, plant height, number of leaves, leaf area, fresh plant weight, dry plants weight, shoot root ratio, percentage of mycorrhiza fungi infection to plant roots. Results of study revealed that the treatments contains mycorrhiza fungi propagules @ 100 g per polybag show superiority over all the tested treatments in improving plant growth characteristics and yield of mustard plant.
