Abstract
The present field experiment was conducted during kharif season 2022-23 with a view to study the “Effect of foliar application of Nano-urea on growth,yield of sunflower. (Helianthus annuus L.)” The experiment was conducted in randomized block design and the treatment was ten with three replications. Results revealed that treatment T10- 100 % (RDN)+3 foliar sprays of Nano-urea 0.4 % at 30,45 and 60 DAS. recorded the highest seed and straw yield, growth parameters Which was significantly superior over all the treatments but was at par with treatmentT9-100% (RDN) + 2 foliar sprays of 0.4% Nano-urea at 45 and 60 DAS. Treatment T8- 100% RDN+1 foliar spray of 0.4 % Nano-urea at 30DAS and treatment T7-75 % RDN+ 3 foliar sprays of 0.4 % Nano-urea at 30, 45 and 60 DAS.
