The present study was carried out during 2013 and 2014 growing seasons to evaluate the effect of different levels of iron in growth and some yield properties of date palm Kadrawi Basrah. The experiment consisted of adding 5 levels of iron; 0, 5, 10, 15 and 20gm Fe palm-1 as FeSO4.7H2O (19% Fe) at three doses. Randomized complete block design with three replicates was used in this study.
The results showed that the levels of Fe significantly increased some characteristics of date palm for two seasons. 20gm Fe palm-1 level was superior in giving highest values for those characteristics. The percentage increases of these characteristics for season /2013 were 23.3, 34.5, and 66.2% for fruit weight, fruit volume, and chlorophyll content respectively while the percentage increase for season / 2014 were 24.6, 34.5, and 66.6% for those characteristics respectively as compared with control. The percentage increases of dry weight, total soluble solids (TSS), reducing sugars, non reducing sugars and total sugars respectively for season /2013 were 25.9 28.0, 24.5, 19.3 and 32.0% while for season/2014 were 27.3, 36.6, 36.4, 20.4 and 34.1% respectively as compared with control. |
