ABSTRACT
This manuscript focues on the effect of macronutrients on growth and uptake pattern of hybrid sunflower under irrigated condition and for this field experiment was conducted at Agricultural Research Station, Bhavanisagar , Tamil Nadu Agricultural University . 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). Significant higher growth attributes, dry matter production, yields (seed, stover) and nutrient uptake pattern was observed with NPK @ 120:90:90 kg ha-1 (T7). Treatment T7 proved its superiority by recording 11.73, 25.64, 25.74 % increased uptake of N, P, K respectively over recommended dose of fertilizers (T10) i.e. NPK @ 60:90:60 kg ha-1. Hence NPK @ 120:90:90 kg ha-1 (T7) was observed most suitable to obtain maximum yield of hybrid sunflower under irrigated condition.
