STUDIES ON GROWTH AND YIELD OF SESAME (SESAMUM INDICUM) AS INFLUENCED BY DIFFERENT LEVELS OF NITROGEN AND NANO UREASurya Dev Singh, Dhanshree Bharat Jadhav, Sushant Sukumar Patil, Avani Hari and Achala AggarwalAbstract A field experiment entitled âStudies on growth and yield of sesame (Sesamum indicum) as influenced by different levels of nitrogen and nano ureaâ was conducted at Agronomy fields of Lovely Professional University, Phagwara, Punjab during the kharif season of 2022-23. The experimental field had sandy loam soil with pH 8.27. The experiment consisted twelve treatments arranged in Split Plot Design which was replicated thrice. The main plot consisted of three levels of mineral nitrogen (urea) viz. F1-0%, F2- 50%, F3- 100% and subplot consisted of four levels of nano urea form of nitrogen viz. N1- 0%, N2- 10%, N3- 20%, N4-25%. Among the mineral nitrogen application, highest of all growth and yield parameters were recorded with F3 and lower growth and yield parameters recorded with F1. Similarly in case of nano nitrogen foliar application, highest of growth and yield parameters recorded with N4 which was found to be on par with N3 and the lowest of all the parameters recorded with N1. However, their interaction was found to be nonsignificant for all the parameters of the study. |
