Effect of micronutrients on growth, flower quality and yield of China aster (Callistephus chinensis L) under Allahabad agro climatic condition

The present experiment was carried out during November, 2018 to February, 2019 in Departmental Research Field of Department of Horticulture, SHUATS, Prayagraj. The experiment was conducted in Randomized Block Design (RBD), with ten treatments of Micronutrients, the treatments were replicated thrice. The treatments were T0 (RDF (Control)), T1 (RDF + Boron 0.2%), T2 (RDF + Boron 0.4%), T3 (RDF + Boron 0.6%), T4 (RDF + Zinc 0.2%), T5 (RDF + Zinc 0.4%), T6 (RDF + Zinc 0.6%), T7 (RDF + Iron 0.2%), T8 (RDF + Iron 0.4%) and T9 (RDF + Iron 0.6%). From the present investigation it is found that the treatment T5 (RDF + Zinc 0.4%) found best in terms of Growth, Yield and quality parameters of China Aster followed by treatment T4 (RDF + Zinc 0.2%). In terms of economics of different treatments, maximum Gross Return, Net Return and Cost Benefit ratio was also found in T5 followed by treatment T4 where as minimum was recorded in treatment T0 (Control).
