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.
