Abstract
A pot experiment was carried out to study the effect of two types of mycorrhiza isolated from sorghum(Sorghum biocolor L.), and onion (Allium ceba) crops as compared to the addition of triple superphosphate on the growth of sorghum grown on a clay soil from Khartoum State, Sudan. The experiment was conducted during June–August 2011 under shadow in the demonstration farm, Sudan University, College of agricultural Studies, Shambat lat.(15o 40 N) long.(32 o 32E ), Sudan. The mycorrhiza was added at the rate of 300 spores / pot, while the mineral fertilizer was applied at the recommended dose 0.03g/pot (40kg triple superphosphate/ha).The design adopted was a Completely Randomized Design(CRD) with three replications. Plant samples were taken after four weeks from sowing and at harvest(8 weeks from sowing) to determine root colonization by mycorrhiza, plant height, root length, shoot dry weight, and root dry weight, in addition to shoot phosphorus content, and spores density. The results indicated significant differences in root colonization after four weeks from sowing and at harvest, upon addition of the mycorrhiza isolated from sorghum compared to the one isolated from onion . The infection was depressed when phosphorus fertilizer (P) was added to both types of mycorrhiza .However, the addition of mycorrhiza alone was superior to the addition of mineral P with mycorrhiza and to the addition of P alone. The results also revealed significant differences in plant height, root length, shoot dry weight, and root dry weight. The best results were obtained upon the addition of the mycorrhiza isolated from sorghum, compared to that isolated from onion. But when phosphorus fertilizer was used with mycorrhiza, all the measured traits were depressed. Also, the results indicated significant differences in spores density. High density was obtained when the sorghum mycorrhiza was added alone, and with onion mycorrhiza when mineral P was added as compared with other treatments. The results revealed highly significant differences in shoot phosphorus , especially when the plants were inoculated with sorghum mycorrhiza , followed by onion mycorrhiza. Both treatments gave high shoot phosphorus content compared to other treatments and to the control treatment.
