Response of Sunflower (Helianthus annuus L.) to Nitrogen Levels in Irrigated Areas in Somalia

Aims: SARTEC conducted an experimental study with the objective of determining effects various nitrogen rates on sunflower growth and yield in Afgoi district, Lower Shabelle region.
 Materials Methods: The was carried out at farm during Der season 2020. experiment used a Russian kind laid Randomized Complete Block Design (RCBD) four replications plots for each. crop fertilized different N 50, 100, 150 kg ha-1, control/unfertilized plot included each replications. Plant height, head diameter, hundred-seed weight, seed, straw, biological yield, as well harvest index, were all measured five plants from data collection.
 Results: fertilizer applied to resulted highly significant variations components. Seed-related parameters like seed weight influenced substantially more than other variables, including plant height; stem straw yield. Despite having highest ha-1 not cost-effective 100 ha-1.
 Conclusion: In Somalia, per hectare is ideal rate maximizing revenue production while adhering best management practices.
