Abstract
A greenhouse experiment was carried out to investigate the influence of Glomus clarum (mycorrhiza) on the growth of tomato seedlings grown in both sterilized and non-sterilized soils. Highest growth parameter values were recorded in tomato plants inoculated with mycorrhiza but grown in sterilized soil, followed by those grown in non-sterilized soil but inoculated with mycorrhiza also. Sterilized but non-inoculated tomato plants also had growth and were closely followed by non-sterilized, non-inoculated tomato plants. There was no significant difference in all the treatments when girth of the tomato plants used was measured in this study. Nutrient uptake (N,P,K) was significantly found highest in the inoculated sterilized tomato plants while it was found lowest in the non-sterilized, non-inoculated tomato plants. Generally, mycorrhizal-inoculated tomato plants (whether sterilized or non-sterilized) showed better growth in all the treatments used.
