EFFECT OF APPLICATION OF NANO-UREA ON MAIZE (C-1415 VARIETY) GROWTH AND YIELD UNDER PUNJAB CONDITIONSAvick Kumar Kundu and Vandna ChhabraAbstract To meet the increasing demand for food due to the increasing population, nitrogen fertilizers are being used extensively. Uncontrolled use of nitrogen leads to decreased soil health along with polluting the environment. Maize is one of the important crops in the rainfed regions of Punjab. Therefore, there is a need to optimize the usage of nitrogen fertilizers and thatâs where nano fertilizers come in. The current investigation was conducted in an RBD (Randomized block design) with 9 treatments and 3 replications. The study showed that the application of 75 % RDN + foliar spray of nano urea 0.1% at knee high and tasseling stage gave superior results concerning growth and yield attributes in kharif maize. However, since the application of 75 % RDN + 2 foliar spray of nano urea at knee high and tasseling stage was significantly at par with a full doze of RDN, therefore this might be an appropriate management alternative for sustainable cultivation practice of maize. |
