Effect of different nutrient management practices on growth and yield of hybrid sunflower (Helianthus annuus L.)

Abstract

A field experiment was conducted during rabi season of 2009-10 at oilseeds research station, Latur to study the effect of different nutrient management practices on growth and yield of hybrid sunflower (LSFH-35). The investigation was carried out in RBD design with three replication and nine no. of treatments (different fertilizer levels along with micronutrient involving nine treatment combinations were tested) such as T1 = 100% NP, T2 = 50% RDF, T3 = 100% RDF, T4 = 150% RDF,T5 = RDF + Sulphur, T6 = RDF + Sulphur + Boron, T7 = RDF + Sulphur + Boron + Zinc, T8 = RDF + Sulphur + Zinc, T9 = control. The result of experiment revealed that among the treatments, application of 150% RDF was recorded significantly higher growth, yield attributes and yield over T9 (control), T2 (50% RDF), T1 (100% NP) and T3 (100% RDF), whereas, it was at par with the application of T7 (RDF + S + B + Zn), T6 (RDF + S + B), T8 (RDF + S + Zn) and T5 (RDF + S).
