| This study was conducted in one of agriculture field in Abu-Khasib village at Basra province .so the aim of this study is to know the values of effect some of chemical fertilizer and its urine and the aim is to provide the nitrogen elements and also to know the effect of fertilizer type triple super phosphate as like a source of phosphor and Sulfate potassium as like a source of potassium elements. The ratio of fertilizer which was added to date palm (2:1:1)(N.P.K)and(2:1:2)(N.P.K) so the depth of fertilizer add with differ value (15cm)and(30cm) after that’s the results shown of fertilizer with ratio (2:1:2) and (2:1:1) added with depth (30cm)that’s lead to the increment growth of date palm ,also recorded the highest moral increment in the number of date palm leaves rate and also increment the value contents of chlorophyll and carbohydrate and protein value in leaves too and with values as follow( 3.063% ,2.563%, 0.1690%, 13.10% ) and this is also lead to moral increment in concentration of minerals (N.P.K) of leaves to date-palms of Barhi cultivar . | ||
