| Abstract | ||
| Afield experiment was conducted in AL-Badaa station, AL-Shatra in ThI-Qar governorat during the growing season (2013) to study the effect of three rate of nitrogen , phosphorus and their interactions in two time of application on physical properties of date palm ( Shwathii) during different stage of fruit growth( Khalal ,Ritab, Tamar),and studied minerals leaves content. Results indicated that Adding different levels of nitrogen and phosphorus had a significant effect in increasing fruit weight , seeds weight , fruit volume, length and diameters of fruit during different stage of fruit growth . 3 Kg N/Date palm /year and 1 Kg P/Date palm /yaer, rates confirmed higher asignificant of fruit weight compare with control treatment . Intraction between nitrogen and phosphours had significant effects in fruit weight .(3Kg N/Date palm /year +1KgP/Date palm /year ) treatment gave higher asignificant of studied properties . Statistical analytical results showed , there were a significant effects between time of nitrogen and phosphours fertilizer application and their intractions on physical properties of date palm . The second time of application was significantly increased the fruit weight , pulp weight and fruit volume during Khalal period , and fruit volume and its diameter during Ritab and Tamar period respectively. | ||
