Abstract
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 2016–17 and 2017–18 across three locations in the Pothwar region, Pakistan, aimed to assess Camelina sativa's 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-1notably 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-1), and biological yield (7952.7 kg ha-1). Conversely, control treatments yielded minimal results. Furthermore, NARC exhibited the tallest plants (94.7cm) and highest biological yield (7708 kg ha-1), 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-1).Oil content decreased with rising NPK levels, while protein content displayed an inverse relationship. NPK @ 50:30:20 kg ha-1resulted 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-1) enhanced Camelina yield attributes under diverse precipitation conditions
