Abstracts |
In a pot experiment, the interactive effects of sewage sludge (SS) and arbuscular-mycorrhizal (AM) colonization on nutrients uptake and growth of barley plant (Hordum vulgare L.) were studied. The experiment was arranged in a completely randomized design consisting of a 4× 3 factorial combination of four SS rates (0, 10, 20 and 30 g Kg-1 soil) and three mycorrhiza states (Glomus intraradices, Glomus mosseae and without mycorrhiza). The treatments were replicated three times. The result of this study showed that both shoot and root dry weights of M plants were significantly greater than those of NM plants. Root colonization of barley plant by G. intraradices was higher than by G. mosseae. This resulted in a greater mycorrhizal growth response of G. intraradices than that of G. mosseae. Increasing SS increased plant dry weight of both M and NM plants, although the beneficial effects of mycorrhizal colonization of both AM fungi was decreased with increasing SS. In NM treatment, increasing SS increased leaf P concentration. Mycorrhizal colonization of both AM fungi significantly increased leaf P concentration at all SS levels. Despite mycorrhizal growth response, mycorrhizal P response was not much affected by SS application. Inoculation of the soil with both of AM fungi stimulated significant H. vulgare growth and significantly increases in shoot tissue content of P, K, Fe, Mn, Zn and Cu. The experimental setup provided a suitable tool for evaluating SS in combination with AM fungi as a biological fertilizer for its beneficial effects on H. Vulgare plant growth. |
