In order to study the effects of reducivs irrigation water alkalinity and acidity on quality and quantify of geranium growth in pot with soil mixteur medium , the research work was carried out during 2007-2008 in a green house ,using a factorial assay and a randomized complete block design with three replication. The main plot assigned to cultivar (white and red colored flower geranium) and the subplot assigned to irrigation water acidity viz, pH1=4, pH2= 4/5, pH3=5, pH4=5/5, pH5=6 and pH6(well water)=7/8.Results showed that irrigation water acidification significantly increased number of total flowers and opened flowers per inflorescence ,chlorophil and magnesium content of leaves. But its effects on petiole length was not significant. Cultivar and water acidification interactions had highly significant impacts on stem length, leaf size, fresh and dry weight of plant foliages , number of inflorescence per plant and Iron content and significant impacts on inflorescence diameter and number of lateral branches at five percent of probability. Comparison of means and neutralizing alkalinity and acidifying of irrigation water to PH=5/5 con increase nutrients absorbsion and improve quantitative and qualitative traits of geranium
