Abstract
Two field experiments were conducted at Sids agricultural Research Station to study the response of three sunflower cultivars, namely Maik, Vedoc and Eroflour to some bio-nitrogen fertilization treatments, i.e. control, inoculation with Rhizobacterien,
"- inoculation with Rhizobacterien plus 10 kg NI fed, inoculation with Rhizobacterien plus 20 kg NI fed and 30 kg NI fed under three hill spaces ( 20, 25 and 30 cm between hills) and their effects on some growth characters, yield and yield components as well as oil content and oil yield per fed.
Results showed that, cultivars significantly differed in all characters under study. It was clear that Eroflour cultivar surpassed the other two varieties in most studied parameters, except plant height (cm) and 100- seed weight (gm) where Maik cultivar gave the tallest sunflower plant, while 100- seed weight (gm) was not affected by cultivars.
Decrease the plant distances (20 cm between hills) led to a significant increase in plant height and both seeds and oil yields per fed, while both stem and head diameter, 100- seed weight and seeds weight per head had a reverse trend. Oil content was not affected by plant density.
As for bio- nitrogen fertilization, all studied characters significantly increased by increasing nitrogen levels up to 30 kg NI fed. Inoculation of sunflower seeds with Rhizobacterien plus application of 20 kg NI fed gave seeds yield per fed. equal to that of fertilization with 30 kg NI fed, where no significance differences between them.
In general, the interactions among the three studied cultivars was significant on all traits studied herein.
It could be concluded that using Eroflour cultivar under 20 cm between hills.
Also, seed inoculate the seed with Rhizobacteries as bio-fertilizer plus 20 kg NI fed produced the highest seeds and oil yieldsl fed.
