Abstract

Objective: This study aimed to investigate the impact of varying of NPK fertilization doses and seed rates on barley (Hordeum vulgare) yield, yield components, and inorganic nitrogen (NH4-N and NO3-N) dynamics in semi-arid conditions without artificial irrigation. Material and Methods: The field experiment was conducted at the Gobustan Experimental Station from October 2018 to June 2019, utilizing the "Celilabad-19" barley variety. A randomized complete block design with four replications was employed, incorporating various seed rates and NPK fertilizer treatments. Plant and soil samples were collected at different phenological stages, and analyses included grain and straw yield, yield parameters, total N content of plant, and soil NH4-N and NO3-N levels. Results and Discussion: The results the treatment with a seed rate of 140 kg/ha and N60P45K45 fertilizer application consistently demonstrated the highest aboveground biomass, grain, and straw yields. This treatment exhibited optimal N content during the Full Maturity stage of plant. Conclusion: In conclusion, this study has provided insights into optimizing barley cultivation practices in semi-arid climates, such as seed rate and NPK fertilizer dose. With a seed rate of 140 kg/ha and N60P45K45 fertilizer application, the highest yield and performance indicators were achieved in the “Celilabad-19” barley variety.
