Abstract

2 Abstract: In order to sustainable production of corn by seed inoculation with Mycorrhiza strains a factorial field experiment was conducted during 2010-2011. Studied factors were Mycorrhiza strains (Glomus intraradics and G. mosseice) and phosphorous fertilization included 33%, 67% and 100% of recommended dose of super phosphate triple. There was a field with neither inoculation with Mycorrhiza nor phosphorous fertilization as control. Results revealed that the effects of Mycorrhiza strains and phosphorous fertilization on crop height were significant. When seeds inoculated with Mycorrhiza strains, corn plants were taller than non- treated ones. The corn seeds inoculated with G. intraradics and G. mosseice had higher LAI than check plants. Maximum LAI obtained from crop plants fertilized with 67% recommended dose of phosphorous and these plants could improve their LAI up to 3.65. In non-inoculated seeds with increasing of phosphorous fertilization rate grain yield improved, significantly and yield produced in 100% recommended dose of phosphorous was nearly 6.43 tha . Whereas, in those seeds inoculated with Mycorrhiza strains and fertilized with 67% 1 recommended dose of phosphorous, yield improved 31%. Higher grain phosphorous content was observed in treatments of 67% recommended dose of phosphorous plus inoculated seeds. Increasing of grain phosphorous content in non-biofertilized seeds experiencd linear trend with increasing of phosphorous application rate. Corn seeds biofertilization with both G. intraradics and G. mosseice Mycorrhiza strains may reduce in phosphorous fertilizer application rate in semi-arid regions and it can be resulting in reduction of fertilizers environmental hazards in sustainable maize production.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
