ผลของเชื้อรา Arbuscular Mycorrhizal ต่อการเจริญเติบโตและผลผลิต ของข้าวโพดฝักอ่อน (Zea mays Linn.) ในดินโครงกระดูกภายใต้ดินที่ไม่ผ่านการฆ่าเชื้อ

Abstract

Effects of Arbuscular mycorrhizal fungi (AMF) on baby corn growth was studied to observe how AMF promoting baby corn. The experiment was set at Faculty of Agriculture Technology, Buriram Rajabhat University. The CRD was designed for this experiment with 5 treatments namely 1) no AMF inoculation 2) inoculated with Glomus sp 2 3) inoculated with Glomus sp 3 4) inoculated with Glomus mosseae and 5) recommended rate of chemical fertilizer using 15-15-15 and 46-0-0. ANOVA and mean comparison using DMRT was analyzed for height, number of leaf, yield, fresh weight and dry weight using DMRT SPSS v 11. AMF colonization was also examined in baby corn root after harvesting. AMF application showed no significantly (p>0.05) increase of baby corn height, number of leaf, fresh weight and dry weight while chemical fertilizer application showed highly significant (p<0.01) increase growth of baby corn. Glomus mosseae showed trend to increase baby corn growth more than Glomus sp 3 and Glomus sp 2 while Glomus sp 2 showed trend to increase baby corn yield more than other. However all of AMF, Glomus sp 2, and Glomus sp 3, showed low colonization (1-5%) in baby corn root under skeletal soil natural condition. The result showed that AMF should not be used as biofertilizer to promote baby corn growth in skeletal soil under natural condition.
