Nano Nitrogen for Increasingyield of Maize (Zea mays L.)

Nitrogen fertilizers play an important role in the cultivation of crops, excessive and improper usage of fertilizers cause severe issues with respect to human and environment. It is essential to go for alternative sources of nitrogen like nano nitrogen with slow and controlled release of nitrogen.An experiment was conducted at Agriculture Research Farm, Lovely Professional University, Phagwara, during kharif 2022 by using the nano source of nitrogen in maize crop.The experiment was laid out in the randomized block design with eight treatments replicated thrice.Among the different combinations of recommended dose of fertilizers along with nano urea the treatment applied with 100% N+Nano N applied twice at 30 and 60 days after sowing(T6) was thebest treatmentin terms of growth and yield (7.2 t/ha).
