Abstract

With the increasing need to develop sustainable agricultural systems, this research aims to evaluate the effectiveness of biofertilization with Azospirillum spp bacteria and organic fertilization with banana peels in improving the performance of sunflower plants. Then the seeds were planted on 2024/3/3 in holes ,The experiment was conducted in a factorial arrangement and with a randomized complete block design (RCBD) with three replications, including two factors in the experiment: The first factor: concentrations from banana peel ( 0 ,50,75,100 gm\kg ) , The second factor: concentrations from Azospirillum ( 0 ,50,75,100 ml.L-1 ) , The studied traits The number of seeds in the disk seed disk-1 , Weight of 100 seed g., Biological yield Mgha. L-1, The active compounds oleic acid and thymol. The results indicate a significant effect between the banana peel treatments and Azospirillum biofertilizer, with the (100 g/kg) treatment outperforming the others, yielding the highest average of number of seeds in the disk seed disk-1 ( 1986.75 seed disk-1 and 1813.25 ) , Weight of 100 ( 57.17 and 57.85 seed g), Biological yield ( 74.76 and 77.24 Mgha. L-1 ) , oleic acid ( 7.59 and 8.36 % ), thymol ( 7.46 and 9.45% ).
