| Abstract : This study was conducted in experimental field, department of horticulture , college of agriculture –university of Baghdad , in Abo Graib area for two seasons of spring for years 2011 , 2012 for potatoes yield . This study was included the effect of using of three type from nitrogen fertilizer, as well as to comparison procedure ( Zero) , and two anti- transpiration , as well as to comparison procedure ( Zero). This study was made by using the activity experiences (4*3) within the design RCBD with three repeated , therefore we have 36 experimental units , and after complete the indicators of field and laboratory study the medium was compared for account less moral difference L.S.D. at level of possibility 5% by using program of SAS in the statistics analysis.We can abstract the following results :Superiority of all the resources of nitrogen fertilizer for studded grocer descriptions with comparison procedure if give it N2A0 upper high for plant in the first season as ( 77.8 Cm. ) , and the procedure N2A2 upper high of plant in the second season , and upper leafy area in the first season as (89.4 Cm. , 5003,4 Cm2) continuously, but the procedure N2A1 gave upper rate for number of leafs , and leafy area in the second season as ( 89.5 leaf/plant , 8743 Cm2) continuously, but the procedure N3A2 gave upper number of leaf in the first season as ( 51.5 leaf /plant ) The fertilizer procedures have moral affect in the descriptions of the quantity yield , so that this procedure N1A0 passed by give it upper rate for the weight of the tubercles , and economical yield in the first season as ( 859.3 gm., and 50549 ton/H.) continuously , but in the second season the procedure N1A1 as upper rate of weight for the tubercles and economical yield as ( 1007 gm. And 69051 ton / H ) | ||
