13191 10.30848/PJB2025-2(3) <p> Allometric variations in Camelina sativa L. in response to environmental factors and nutrient levels</p> Arshid Munir, Fayyaz-Ul-Hassan, Abdul Manaf, Ehsan Ul Haq, Muhammad Kusar Nawaz Shah and Tamoor Hussain <p> Climate change poses challenges for plant species in less hospitable regions, yet resilient varieties like Camelina sativa may thrive. This study, conducted during the winter seasons of 2016&ndash;17 and 2017&ndash;18 across three locations in the Pothwar region, Pakistan, aimed to assess <em>Camelina sativa&#39;s</em> adaptability to varying environments and macronutrient levels. Employing five nitrogen (N) and phosphorus (P) rates alongside a constant potassium (K) rate, the experiment utilized a randomized complete block design with a split-plot arrangement. Results indicated significant effects from all factors tested (NPK levels, locations, and years). Application of NPK @ 50:30:20 kg ha<sup>-1</sup>notably enhanced plant height (119.45cm), pod count per plant (804.8), seeds per pod (19.9), thousand seed weight (1.84 g), seed yield (1789 kg ha<sup>-1</sup>), and biological yield (7952.7 kg ha<sup>-1</sup>). Conversely, control treatments yielded minimal results. Furthermore, NARC exhibited the tallest plants (94.7cm) and highest biological yield (7708 kg ha<sup>-1</sup>), while Talagang showed superior attributes such as pod count per plant (449.9), seeds per pod (14.7), thousand seed weight (1.41g), and seed yield (1437 kg ha<sup>-1</sup>).Oil content decreased with rising NPK levels, while protein content displayed an inverse relationship. NPK @ 50:30:20 kg ha<sup>-1</sup>resulted in lower oil content (40.8%), but higher protein content (34.1%) compared to controls. Overall, oil and protein content exhibited a negative correlation and responded significantly to NPK variations. Application of NPK fertilizers notably improved Camelina growth, yield, and quality traits across precipitation levels. NPK fertilizers (50:30:20 kg ha<sup>-1</sup>) enhanced Camelina yield attributes under diverse precipitation conditions</p> Published 2025 57 2 535 542
