Abstract
The field experiment was carried out in 2013 to 2014 rainy season at the Main Agricultural Research Station, UAS, Raichur, India to study the response of soil test crop response (STCR) approach on the yield and quality of Sunflower (Helianthus annuus L.). The experiment was laid out by Randomized Complete Block Design (RCBD) design with three replications. The analysis of variance revealed that the application of fertilizers based on STCR along with foliar application of micro-nutrients significantly recorded higher head diameter, 100 seed weight, , number of filled seed head-1,seed filling per cent, seed yield ha-1, Stover yield ha-1, oil content and oil yield ha-1. Further a higher gross return, net returns and benefit-cost ratio (BCR) were observed when compared to the other treatment combinations carried out during the experiment viz., recommended dose fertilizer (RDF) of NPK (Control). Overall, we concluded that the input of STCR approach had positive effects on quantitative and qualitative traits of sunflower in conditions of studied area as compared to RDF method. Key words: Sunflower, recommended dose fertilizer (RDF), soil test crop response (STCR), foliar application, oil content, benefit-cost ratio (BCR).
