  • Abstract:
  • A field experiment was carried out in the Experimental farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu, India during March 2024 to study on utilization of various organic sources on seed yield, quality, nutrient uptake, and economics of hybrid sunflower (Helianthus annuus L.). The experiment was laid out in Randomized Block Design (RBD) comprised of nine treatments and replicated thrice. The treatments are T1 – Control, T2 - FYM @ 12.5t ha-1 + 50% RDF + Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS),T3 - Vermicompost @ 2.5t ha-1+ 50% RDF + Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS), T4 - Press mud @ 10t ha-1+ 50% RDF + Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS),T5 - Enriched FYM @ 750 kg ha-1+ 50% RDF + Panchakavya @ 3 % (foliar spray twice at 30 and 45DAS), T6 - Enriched vermicompost @ 750 kg ha-1 + 50% RDF + Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS ,T7 - Enriched press mud @ 750 kg ha-1+ 50% RDF + Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS), T8 - 100% RDF + Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS) ,T9 - 100% RDF alone. From the results, it was revealed that application of enriched vermicompost @ 750 kg ha-1 + 50% RDF + Foliar spraying of Panchakavya @ 3% (foliar spray twice at 30 and 45 DAS) recorded the maximum seed yield (3227 kg ha-1), quality, Nutrient uptake N (90.43 kg ha-1),P (25.25 kg ha-1),K (90.26kg ha-1) and net return (113500.8) of hybrid sunflower.
