Abstract: In order to find out the response of soil and foliar application of zinc and iron fertilization on Sunflower (Helianthus Annus L.) yield and economics. A field experiment was conducted during the kharif 2012at Agricultural College Farm, Raichur, the results revealed that, yield and yield components of sunflower were influenced favourably by soil application of ZnSO4@ 10 kg ha-1 + Foliar spray of FeSO4@ 0.5 % along with RDF and FYM @ 8 t ha-1 recorded significantly highest grain yield (2,268 kg ha-1), oil yield (937 ha-1), oil content (41.3%) and test weight (5.47 g). The growth parameters of sunflower were also influenced favourably with soil application of ZnSO4 @ 10 kg ha-1 + Foliar spray of FeSO4@ 0.5 % along with RDF and FYM @ 8 t ha-1, dry matter production (106.8 g plant-1) and plant height (189.2 cm), over other treatment combinations. The highest net returns of Rs.58, 453ha-1 and B: C (3.46) was recorded in soil application of ZnSO4 @ 10 kg ha-1 + Foliar spray of FeSO4@ 0.5 % along with RDF and FYM @ 8 t ha-1 to RDF (2.68).
