Impact of NPK fertilizers on growth attributes and micronutrient uptake patterns of hybrid sunflower

Present experiment comprised of macronutrient treatments consisted of five levels of nitrogen (0, 30, 60, 90 and 120 Kg N ha⁻¹), four levels of phosphorus (0, 30, 60 and 90 Kg P₂O₅ ha⁻¹) and four levels of potassium (0, 30, 60 and 90 Kg K₂O ha⁻¹). Increasing levels of NPK increased growth parameters like plant height, leaf area index. Yield components also increased with increasing levels of NPK. Maximum seed yield (2006 Kg ha⁻¹) was recorded with NPK @ 120:90:90 Kg ha⁻¹ (T₇). Cu, Fe and Mn uptake was observed maximum in T7 but Zn uptake was observed higher with NPK @ 120:60:60 Kg ha⁻¹ (T6).
