Impact of NPK fertilizers on growth attributes and micronutrient uptake patterns of hybrid sunflower
2015
Kumar, Aditya | Krishnamurthi, V.V.
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).
