| Abstract | ||
| This study aims to the impacts of organic manures and NPK fertilizers on the growth of plants, lyield, and yield components during the winter growing season of 2023-2024 at the Gardarasha Field, College of Agricultural Engineering Sciences, Salahaddin University-Erbil. A factorial randomized complete block design (RCBD) was used to evaluate the single and combined effects of three levels of manure (0, 10, and 20 t ha⁻¹) and NPK (0, 50, and 100 kg ha⁻¹). The results showed that moderate manure treatment (10 t ha⁻¹) combined with 50 kg ha⁻¹ NPK significantly boosted growth parameters, including plant height, stem diameter, and technical stem length, while maximizing yield components such as total fresh yield (131.53 g) and seed yield (35.70 g). Additionally, both above yield parameters were significantly improvised when organic manure was added at the rate of 10 kg ha-1 (101.18 and 25.72 g), respectively, while it was dropped to (74.21 and 16.36 g), respectively when NPK was added at the rate of (100 kg ha-1). This combination lowers environmental hazards and production costs, promoting sustainable and productive flax agriculture. The compost analysis shows a carbon content of 21.04% and a nitrogen content of 1.05%, for a C/N ratio of approximately 20:1, which is optimum for compost maturity and nutrient release. This balance improves soil fertility and nutrient uptake, promoting plant development | ||
