Abstract
Supplementation of the pots with soil containing spores of Glomus fasciculatum (Thaxter sensu Gerdemann) Gerdemann and Trappe enhanced the root infection from 55 per cent in the control to 98 per cent at the end of five months in black pepper plants. The growth of plants varied directly in proportion with the percentage of root infection. The phosphate levels used in the study did not adversely affect the mycorrhizal population. Mycorrhizal plants showed statistically significant increase in the tissue N, P and leaf nitrate reductase activity over the control. The nitrate compensation point (NCP) was lower in mycorrhizal plants than in the control.
