| Abstract: | Different types of nursery inocula formulations, namely mixed indigenous cultures and Glomus intraradices Schenck and Smith, were compared with commercially available inoculants of AM fungi in a pot experiment using two horticultural crops, Capsicum and Polianthes. Soil-based inocula and soil beads produced the highest response in both crops. Glomus intraradices resulted in the highest yield in both Polianthes (45% increase in spike length) and Capsicum (112% increase in fruit yield). Among the commercial inocula tested, only Mycorise enhanced spike length (33%) and fruit yield (11%) in the two hosts. Overall AM colonization was higher in Polianthes than in Capsicum. Sheared root inocula of G. intraradices resulted in high colonization (upto 68%) but the yield enhancement was lower than with soil-based formulations. The mixed indigenous culture produced the highest number of spores and propagules and commercial inocula the lowest. Accepted: 2 February 1998 |
