English Abstract

Greenhouse experiment was carried out during summer season 2011/2012 at Agriculture research Station, Rabba, Mu'tah University in the southern part of Jordan.

This study aims to investigate the response of pot grown tomato (Lycopersicon esculentum Mill Var.

lorely F1) to inoculation with arbuscular mycorrhiza fungi and application of organic (as mixture of chicken sheep and cow manure) and chemical fertilizers, under glass house conditions.

Chemical fertilizer as (N, P, K20-20-20TE) was application at four levels (0, 625, 1250, and 1875 kg/ha) and organic fertilizer levels was applied at three (0, 12.5, and 25 ton/ha).Experimental treatments were arranged as a factorial in completely randomized block design with 3 replications for each treatment.

Vegetative growth parameters (plant height, root length, leaf area and shoot dry weight), at flowering stage (50 days after planting) were increased by increasing level of fertilizer of both chemical and organic fertilizers regardless of mycorrhiza status.

But, root length and shoot dry weight were not significantly affected.

At harvest time (80 days after planting), all vegetative parameters (shoot length, root length, leaf area and shoot dry weight) were not significantly affected by the interaction of inorganic, organic fertilizers and mycorrhiza.

The present results showed that the main effect of inorganic, organic fertilizers and mycorrhiza on growth parameters (shoot length, root length, leaf area and shoot dry weight) at both studied growing stages were significantly increased with each increase in fertilizer levels with inoculation of mycorrhiza.

Significant interaction effect (organic and chemical fertilizers and mycorrhiza was noted leaf for P, K, Zn, Cu concentration but not for leaf N and Mn concentration.

On the other hand, the macro and micro nutrient content were not significantly affected except P content.

The main effect of inorganic, organic fertilizers, and mycorrhiza on leaf macro - (N, P and K) and micro (Zn, Cu, and Mn) concentration had significant effect, except inorganic fertilizer and mycorrhiza had insignificant effect on P concentration.

Also, leaf macro- (P and K) and micro (Zn, Cu, and Mn) content were significantly increased with each increase in different fertilizer levels and inoculation with mycorrhiza.

Root colonization by mycorrhizal fungi in inoculated treatment was high especially at low level of organic and chemical fertilizers.

was significantly increased by inoculation with mycorrhiza in combination with the lowest level of organic and inorganic fertilizers.

The highest level of inorganic fertilizer significantly reduced root colonization.

Organic fertilizer had no significant effects.

Inoculation tomato plants with mycorrhiza had pronounced significant effects on root colonization.

At the end of experiment, N soil concentration was not affected by different treatment combinations.

Each increase in inorganic, organic fertilizers and inoculation with mycorrhiza significantly increased P concentration in soil.
