EFFECT OF PATTERN OF AGRICULTURE AND AM FUNGI AND ORGANIC MATTER IN GROWTH OF SORGHUM AND MILLET AT DIFFERENT SALINITY LEVELS.

Abstract

Pots experiment was carried out to study the role of mycorrhiza and organicmatter and the pattern of agriculture on growth of the sorghum and millet atdifferent salinity levels. The results showed a difference in the average of dryweights of sorghum and millet with the significant superiority of the pattern ofbilateral agriculture.Add Mycorrhiza led to a significant increase in dry weight by 38.6%, While theaddition of organic matter increased the dry weight of 44.3%. It turns outthat the highest value of the dry weights were for the treatment of bilateralpattern of agriculture at the treatment of each Mycorrhiza and organic matter atthe level of salinity 8.0 dS.m-1 was 83.03 g. Pot -1 while the lowest value of theplant dry weights of millet was in treatment of no added of both organic matterand mycorrhiza when the salinity level of 24.0 dS.m-1 and amounted to 5.93g.Pot-1.The results show a low rate of infection roots by mycorrhiza with increasinglevels of salinity and that the addition of organic matter increased the infectionrate as the highest rate of injury found in the treatment of the level of salinity L1when add all of the Mycorrhiza and organic matter to the kind of cultivation ofbilateral with 87.5% and the lowest percentage of infection found in the level ofL4 salinity in the absence of organic matter and mycorrhiza in millet with 1.2%.The data shown that the addition of organic matter has increased phosphoruscontent in the vegetation by 8.5, %, while the addition of the Mycorrhizaincreased the content of phosphorus 33.5% and the addition of organic matterand Mycorrhiza with the pattern of agriculture SM has increased the phosphoruscontent in the vegetation compared to no addition of organic matter andmycorrhiza by 49.2% .
