Abstract

Sunflower, an important oil seed crop, needs a balanced nutrition for its optimum growth and thorough maintenance of soil health. A field experiment was conducted to study the effect of integrated use of organic, inorganic and growth regulators on growth, phenology as well as yield of sunflower at Agricultural Experimental Farm, Lovely Professional University Phagwara, Punjab during the spring season of 2023. There were 10 treatments viz. 3 types of organic sources, viz. farmyard manure (FYM), poultry manure and vermicompost, inorganic nutrients and growth regulators. The experiment was laid out in a randomized block design. After analysis, the data clearly showed significant differences among treatments in sunflower growth and yield. Along with that a prominent impact of integrated use of organic, inorganic fertilizers and growth regulators was found under treatments in case of yield. Among all treatments T5-50% N through vermicompost + seed dressing and foliar application of manganese sulphate respectively @ 1.0% and 0.5% at 40 and 60 DAS showed the best results in the case of growth parameters (Plant height, leaf area, number of leaves per plant, stem girth), yield parameters (capitulum weight, capitulum diameter, seeds per head and seed yield), and oil quality parameters (Oil content%, oil recovery and protein content%). 50% N through vermicompost + seed dressing and foliar application of manganese sulphate respectively @ 1.0% and 0.5% at 40 and 60 days after sowing (DAS) is thus recommended for sunflower cultivation in sandy loamy soils considering the growth and yield of sunflower.
