Type: article
Abstract: Field experiments were conducted at Ismailia Agric. Res. Station during the two successive seasons of 1999 and 2000 to study the effect of applying methods of micronutrients mixture ( Fe + Zn +Mn) as coating seeds or foliar spray in combination with four different levels of nitrogen fertilizer; i.e. , 30 , 60 , 90 and 120 kg N/fed on sunflower.plant 'Euroflower hybrid' under sandy soil conditions. The results revealed that: 1- Coating sunflower seeds by mlcronutrlents mixture (Fe +Zn + Mn) increased significantly plant height, leaf area I plant, specific leaf weight, stem diameter, seed yield I plant and seed yield Ifed compared to foiiar spary method with rnlcronutrtients. mixture of Fe, Zn and Mn . Also, coating method increased oil content, protein content, oil and protein yields Ifed compared with foliar application one. 2- Increasing nitrogen fertilizer from 30 up to 120 kg N/fed increased significantly plant height, leaf area I plant , specific leaf weight , stem diameter , head diameter, 100-seed weight, seed yield I plant and seed yield I fed Also, protein content , oil and protein yields I fed increased with raising nitrogen levels. While , oil content decreased with raising nitrogen levels. 3- The interaction between applying methods of micronutrients mixture and nitrogen fertilization showed no statistical effect on all characters under investigatiorr.-- It could be concluded that coating sunflower seeds with rnicronutrients mixture ( Fe + Zn + Mn ) with adding 120 kg N/fed gave the highest productivity of sunflower plants; i.e, seed yield Ifed , oil and protein yields.
