Performance of summer sunflower (Helianthus annuus L.) hybrids under different nutrient management practices in coastal Odisha

Abstract

The field experiment was conducted at Department of Agronomy, College of Agriculture, OUAT, Bhubaneswar during summer 2014 to find out appropriate hybrids and nutrient management practices for summer sunflower. Application of recommended dose of Fertiliser(RDF) i.e. 60-80- 60 kg N, P2O5-K2O ha -1 + ZnSO4 @ 25 kg ha -1 recorded the maximum capitulum diameter (15.60cm), seed yield (2.17 t ha -1 ), stover yield (4.88 t ha -1 ) and oil yield (0.91 t ha -1 ), while application of RDF + Boron@ 1 kg ha-1 recorded the highest number of total seed (970) and filled seed per capitulum (890) with the lowest unfilled seed (80) and sterility percentage (9.0%). The hybrid ‘Super-48’ recorded the highest seed and oil yield of 2.17 and 0.91 t ha -1 , respectively, at recommended dose of fertiliser + ZnSO4 @ 25 kg ha -1 . Experiment was conducted in evaluating the new hybrids in addition to evaluate the response of variety to different nutrient management practices.
