Abstract

A response surface technique was used to analyze the effect of Glomus fasciculatum check for this species in other resources , Pseudomonas fluorescens check for this species in other resources and worm-bed leachate (WBL) on growth, yield and characteristics of tomato ( Lycopersicon esculentum check for this species in other resources Mill). The treatments combined inoculation with or without P. fluorescens or G. fasciculatum and the application of WBL at 20% (v/v) each day or every three days. Plant height, number of leaves and yield of tomato fruits was not affected by the factors studied. However, plants with foliar application of WBL each day developed wider stems than those with an application every three days. The pH of the fruits was lower when WBL was applied every three days compared to a daily application. The soluble solids content of the fruits was higher when WBL was applied daily compared to those sprayed every three days. Plant development was not affected by addition of P. fluorescens, G. fasciculatum or WBL, but WBL changed fruit characteristics.
