Abstract :
In order to determine the effect of foliar application of micronutrient fertilizers and humic acid consumption on the yield and yield components of sesame in the delayed planting date, an experiment was conducted in the research farm of Iraqi Mahalle station in the crop year of 2022. This research was carried out as a completely randomized block design with 9 treatments in 3 replications in the research farm of the Iraqi Mahalle. In each plot, 5 rows were planted, the distance between rows was 40 cm and the distance between replications was 3 meters. The studied traits included plant height, harvest index, seed yield, thousand seed weight and biological yield. The results obtained from this study showed that the treatment with humic acid + micronutrient, control and control + irrigation fertilizer + humic acid fertilizer had the highest biological performance, and the lowest biological performance was related to humic acid irrigation fertilizer and irrigation fertilizer + micronutrient. Also, the weight of one thousand seeds in the control group and the eighth treatment was significantly lower compared to other treatments. These results show that the use of micronutrient fertilizers and humic acid could significantly increase the weight of a thousand seeds. Finally, the seed yield was significantly higher in control, control + humic acid seed, and control + humic acid seed + micronutrient than other treatments. These results show that application of humic acid has better effects on grain yield than other treatments.
