The use of some groups of microorganisms that have specific activity providing nutrients to plant is a good alternative. Arbuscular mycorrhizal (AM) fungi is a best example which enhance plant nutrition by providing especially phosphorous, improving plant growth and increasing crop production. Unfortunately, the use of AM as an inoculant on a large scale is not yet widely used, because of several limitations in obtaining a large amount of inoculum due to several factors, such as low growth, the few species of AM domesticated under in vitro conditions, and high competition with native AM. The rhizomes of Zingiber officinale (ginger) are widely used for their medicinal and flavouring properties, whereas the influence of root symbionts on their growth is poorly understood. The present study aimed to determine the effect of arbuscular mycorrhizal inoculum on seedling growth and quality traits of ginger. The protray experiments was conducted with inoculation of AM to ginger in the green house of Indian Institute of spice research (IISR), Calicut. The experiment was laid out in a completely randomized design with 5 treatments and one replication for each; T1: AM only, T2: AM + vermicompost, T3: AM + chitosan, T4: AM + vermicompost + chitosan, T5: Control. During the field study the 8 different treatment samples of ginger (T1 to T8) which were collected from IISR farm also biochemically analysed. The experiment result shows that there were significant differences in growth and yield characters such as plant height, root length, number of leaves per plant due to the application of arbuscular mycorrhiza, vermicompost, chitosan independently and combinedly. Our results showed that, AM inoculation also increases the effectiveness of vermicompost and chitosan application. Biohemical analysis of AM inoculated rhizomes showed that AM inoculation also improve production of secondary metabolites like phenols, flavonoids, essential oil and crude fibre content. On the whole the study proves that arbuscular mycorrhizae is a best bioinoculant in crop production for increasing growth and quality of ginger and an alternative to harmful chemical fertilize
