Effect of different treatment combination of urea and nano-urea on growth and flowering of calendula (Calendula officinalis)


Vasudevan KM and Dr. Vijay Bahadur

An Experiment was carried out during rabi 2023-2024 at Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) India. To study the effect of different treatment combination of urea and nano-urea on growth and flowering of calendula, CV calypso. The experiment was laid out in Randomized Block Design, replicated 3 times with 12 treatments with different combinations. The characters of growth, flowering and yield are noted. Based on above characters it is concluded that treatment combination T7 (50% N through Urea + Nano-urea @ 4 ml/L (2 sprays)) showed best results of Plant height ( 10.60 (20 days),14.41 (40 days),18.08 (60 days), Plant spread (6.26) 20 days (17.38) 40 days (30.52) 60 days ), Number of branches per plant (3.4 (20 days),8.06 (40 days),20.26 (60 days), Number of leaves per plant (10.93 (20 days),26.36 (40 days),60.35 (60 days), Days to 1st flowering (37.6), Flower weight (5.20g), Flower diameter (6.08 cm), Number of flowers per plant (41.33), Yield per plant (202.24g), Yield per plot (202.24 kg), Flower Yield t/ha (22.60), Importance of conducting this experiment is defined that nano-urea can lead to increased productivity of calendula flowers, thus enhancing the medicinal value and also have considerable interest for potential health benefits.
