011 Effect of Poultry and Cow Manures on Zinc Cadmium and Arsenic Uptake by Two Wheat Genotypes Shiva Torabi Torabi shi@ yahoo com March 2012 Department of Soil Science College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor M Afyuni Abstract Zinc Zn deficiency is important nutritional problem in arid and semi arid regions of the worldwhere cereal crops are the main staple food in these regions One effective solution in correcting Zndeficiency is using agronomic biofortification including application of manure Manure applicationwill improve soil physical chemical and biological properties However by addition of manure toxicheavy metals such as cadmium Cd and arsenic As may also enter the soil The presence of Asespecially in poultry manure is of concern On the other hand long term application of animalmanures may cause heavy metal accumulation in soil and groundwater This study was conducted toevaluate the effect of applying poultry and cow manures and zinc soulphate ZnSO4 on zinc cadmium and arsenic concentrations and uptake by two wheat genotypes The experiment wasconducted in a factorial complete random design with three factors including two wheat genotypes Triticumaestivum L cv Back cross roshan and Triticumaestivum L cv Kavir two animal manures poultry and cow at two levels 10 and 20 ton per hectare and zinc soulphate ZnSO 4 at 20 and 40kilogram per hectare and using soils Roodasht Typic haplo cambids and Lavark Typic haplargids Seven months after wheat cultivation root shoot and grain yield and zinc concentration and uptakewere measured Results showed that addition of the manures soil increased DTPA extractable Zn inboth soils In addition the soil organic matter content was also significantly increased Furthermore the addition of the manures increased zinc concentrations in wheat roots and shoots and the greatestzinc concentration in grain was observed in zinc soulphate ZnSO 4 treatment Grain arsenicconcentration increased in both wheat genotypes after using poultry manure treatment Also thegreatest cadmium concentrations in wheat grain were related to applying cow manure treatmentcompared with other treatments However grain wheat protein content in the manures treatments washigher than zinc soulphate ZnSO4 treatments In addition transfer factor of zinc TF of soil to rootand grain wheat in the manures treatments were more effective than other treatments The wheat root shoot and grain yield were significantly effected in different treatments It was observed that Kavirgenotype had a significantly greater root shoot and grain yields compared to ROOSHAN Also zincconcentration in shoot and grain in Back cross Roshan was higher than Kavir It was showed thatgrain protein content in Kavir genotypes was greater than in Back cross Roshan Also there was apositive correlation between Zn concentration of grains and grain protein content and soil nitrogencontent Kay words Agronomic biofortification Cow manure Poultry manure Arsenic Cadmium Znefficiency Wheat
