EFFECT OF IRON SPRAY AND SOIL MULCHING ON SOME SOIL PROPERTIES AND Capsicum Annvum YIELD UNDER DRIP IRRIGATION SYSTEM

Abstract

Abstract: Afield experiment was conducated during fall season 2006 at al habaniea area 65 west of Baghdad to study the effect iron study with different levels of (0,200,300) mgFe/L on Capsicum crop and soil mulching treatments were:1-sheep wast 2-blach poly ethylene availability of Nitrogen and Phosphor in soil and iron content on Capsicum on fruit. results showed an increase in the availability of Nitrogen and phosphor with soil mulching with poly ethylene and organic matter ,it was (205.02 ,191.54)mg N/kg soil and (25.39 , 31.95)kg P/Kg soil respectively. A significant increase in iron concentration on Capsicum fruits with increase in level of iron spray. It reach to 106.26 and 120.55 mg/kg for the first and second level respectively. a significant increase was noticed with soil mulching with poly ethylene and organic matter it reached to 95.33 and 105.97 mg /kg respectively the highest increase on Capsicum fruits yield with interaction between second level of iron spray and soil mulching with organic matter at reach to 40.13T/h
