THE EFFECT OF INDIGENOUS ARBUSCULAR MYCORRHIZAL FUNGI AND CELLULOLYTIC FUNGI TO THE GROWTH AND PRODUCTION OF MAIZE (ZEA MAYS L.) UNDER DROUGHT STRESS IN INCEPTISOL OF ACEH

The function of indigenous arbuscular mycorrhizal fungi (AMF) has been used to improve soil marginal quality in increasing agriculture yield, meanwhile the combination from indigenous cellulolytic fungi was not investigated yet especially in Inceptisol of Aceh with the limitation of soil water. This research was aimed to know the effect of AMF and indigenous cellulolytic fungi to the growth and production of maize in drought stress in Inceptisol. The research was conducted by using polybag experiment at Inceptisol media from University Farm Station 2 Ie Seuum Krueng Raya (Aceh Besar). The research was used randomized complete block design with nine treatments combination of two factors with three replications. The first factor examined was indigenous AMF inoculation that consists of without AMF, Gigaspora giganteainoculation and Gigaspora gigantea+Acaulospora tuberculatacombinationinoculation, and the second factor was indigenous cellulolytic fungi dose, it was 0, 10, and 20 ml per polybag. The result of the study show that the inoculation of AMF indigenous Gigaspora gigantea and the combination of Gigaspora gigantea+Acaulospora tuberculata give significant effect, compare with control in increasing dryroot weight, root volume, and root colonization, that could influence the enhancement of cob without cornhusk, seed weight and 100 seed weight each plant in Inceptisol with drought stress condition (50% field capacity). The inoculation of AMF 10 g per polybag and combining with cellulolytic fungi 10-20 ml per polybag could increase maize production in drought stress condition from 22,3 g become 49,6 g per plant.
