Abstract
An attempt was made to evaluate the effects of VAM (Vesicular Arbuscular Mycorrhiza) on the growth performance ofMentha longifolia L. at various levels of rock phosphate.Various levels of Rock Phosphate were applied in combinations with VAM or without VAMsuchas “RP0 (Without Phosphate) RP1 (0.05 g), RP2 (0.105 g) and RP3 (0.157 g).Rhizospheric soil from Agave plant with large number of spore of different VAM fungi species i.e.Glomus fasciculatum,G. mosseae and Acaulo sporamellae were applied. Inoculum was used as soil based inoculum. The study revealed significant differences<0.05>among treatments and non-significant differences among replications regarding to the plant shoot length, length of roots, number of leaves, fresh and dry weight at different levels of Rock Phosphate amendments in mycorrhizal and non-mycorrhizal plant species. The best shoot length, Fresh Weight, Dry weight and leaves number in term of mean were recorded in MRP3 and MRP2 while the highest root length in terms of mean was recorded in MRP1 and MRP3.At various levels of Rock phosphate the overall performance of mycorrhizal groups were better than non- mycorrhizal groups
