Abstract

An experiment was carried out during the year 2022-2023 in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu to find out the various levels of nano nutrients on growth and yield of marigold (Tagetes erecta L.) cv. Yellow Benz Tall. The floriculture had been becoming one of the projecting sectors in India, while marigold plays an impending commercial flower that is ahead popularity on excuse of its easy culture, varied flexibility and increasing demand. This study was done to find out the standardize an optimum dose of nutrients and effect of foliar application of nano N and K on growth and yield of marigold. The experiment was laid out in Randomized Block Design with eleven treatments and three replications. Among the various treatments, the treatment T10 (75% N + 100% P + 75% K + Nano N & Nano K) resulted in increased primary branches (11.89), secondary branches (45.89), number of nodes (27.82), stem girth (3.85 cm), days taken for flowering (32.67), duration of flowering (92.38 days), number of flowers per plant (48.52), single flower weight (13.64 g), flower diameter (8.82 cm) and yield per plant (495.68 g). But, the treatment T5 (100% RDF + Nano N & K) resulted in increased plant height (55.02 cm) and internodal length (4.56 cm) was found to be the best combination treatments for improving the growth and yield of marigold.
