Determining the Effect of Micro-nutrient on Plant Growth and Flower Yield of Calendula (Calendula officinalis L.) under Prayagraj Agro-climatic Condition, India

Abstract

The objective of this study was to find out the best level of Micro-nutrient on plant growth and flower yield of Calendula (Calendula officinalis L.) and to work out the economics of different treatments. Under Prayagraj Agro-climatic condition” cv. Calypso II in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, (U.P.), India. During the winter season November, 2021 to February, 2022. The experiment was conducted in Randomized Block Design (RBD), with ten treatments of different level of Micronutrients (Copper, Zinc and Manganese), with thrice replicated. The treatment T7 (0.2% Manganese + RDF) found best in term of plant growth and yield with high benefit cost ratio of Calendula followed by treatment T8 (0.4% Manganese + RDF) where as minimum Plant growth, flower yield and Cost Benefit Ratio was recorded in treatment T0 (Control + RDF).
