MANAGEMENT OF THE ROOT-KNOT NEMATODE OF TOMATO BY INOCULATION WITH ARBUSCULAR MYCORRHIZAL FUNGI (Pages : 48 - 54)

Arbuscular mycorrhizal fungi (AMF) have prospective role in biocontrol of soil-borne diseases. In winter season the experiments were conducted to quantify the interactions between AM fungi [Glomus versiforme (Karsten) Berch] and Meloidogyne incognita and rhizosphere of tomato plants (var. BARI Tomato 2) and to determine their combined effects on the root-knot nematode, Meloidogyne incognita and on tomato growth. AMF spore inoculation includes 60 g, 70 g, 80 g, 90 g, and 100 g spore along with Furadan 5G and without inoculation or control agent was as control. The highest shoot length was recorded in plants inoculated with 70 g AMF spore. The maximum shoot weight was recorded in 100 g AMF spore inoculation (44.33 g). The root length was ranged from 13.40-24.20 g. Significantly higher root length was computed in 100 g AMF spore and it differed significantly with all other inoculation. All the treatments amended with AMF proved their efficiency to establish the root infection. It was found that root infection increased with the increasing of AMF inocula concentration. The minimum gall index of 2.0 at 0-10 scale was assessed in T3, T5 and T6. The maximum yield was harvested from T5 (2740 kg/ha). T5 (100 g AMF spore) gave satisfactory results to reduce root-knot disease and to improve plant growth and yield of Tomato. The results indicate that specific AM fungi can interact to suppress M. incognita, disease development and increases tomato yield.Download
