Abstract
This 2‐year greenhouse study (2022–2023) investigated linseed nutrient needs using a randomized block design. Research studies on nutrient omissions revealed macronutrient and micronutrient impacts on yield and oil quality. Optimal linseed production requires understanding these nutrient roles. Applying appropriate fertilizer based on these findings is essential. This study investigated the impact of full nutrients (NPKSZnB) and individual omissions (N, P, K, S, Zn, B) on Bekoji‐14 linseed variety yield, growth, and quality in clay loam soil. Data analysis revealed nitrogen and phosphorus as key limiting nutrients. Their absence caused significant yield losses, reaching up to 460.94 kg·ha −1 , highlighting these nutrients’ critical roles. A complete nutrient package yielded the highest seed production at 2201.60 kg·ha −1 , outperforming nitrogen and phosphorus treatments by 20.94% and 18.94%, respectively. Sulfur, zinc, and boron deficiencies resulted in smaller yield losses of 3.55%, 2.71%, and 1.99%. The severity of yield reduction ranked: nitrogen, phosphorus, potassium, zinc and boron, sulfur and boron and zinc, sulfur, and finally zinc omissions. Quantitative analysis showed complete fertilizer (NPKSZnB) significantly improved growth, with plant height peaking at 90.05 cm and maturity in 133.21 days. Nitrogen‐omitted plots averaged 72.05 cm tall, highlighting nitrogen’s importance. The maximum capsule count per plant was 37.87. Under full nutrient conditions, the highest seed yield was 2201.60 kg·ha −1 . Nutrient deficiencies significantly decreased yields, reaching 460.94 kg·ha −1 less, highlighting the necessity of full fertilization. Linseed oil content varied from 31.16% to 38.3%, dropping 18.64% without nitrogen. The study urges smallholder farmers to use balanced fertilization with nitrogen and phosphorus for optimal yield and oil quality. Effective nutrient management, considering macro, secondary, and micronutrients, is vital for sustainable linseed production. Further research should explore region‐specific fertilization plans to improve economic viability within Ethiopian linseed farming. This will lead to increased yields, improved oil quality, and enhanced livelihoods.
