An experiment was conducted to ascertain the effects of nano NPK fertilizers and chemical fertilizers on sole maize and intercrop maize growth and yield characteristics at the Lovely Professional University, Punjab agricultural farm. Eight treatments and three replications were used in the split-plot design experiment, which used a cropping system as the main plot and fertilizers as subplots. The intercropping of maize and mungbean produced significantly higher mean values for the number (no.) of leaves, leaf area index (LAI), cob length, cob diameter, cob weight, no. of cobs per plant, no. of grains per cob, test weight (1000 seed weight in g), grain yield, straw yield, biological yield, and harvest index, as compared to the sole maize on the main plot. Furthermore, in the subplot, the combination of nano NPK and Recommended dose of fertilizers (RDF) considerably enhanced maize growth, yield characteristics, and yield in comparison to the other treatments. This study found that the most efficient way to boost crop growth and yield is by intercropping maize with mungbean + 50 % RDF + 50 % NPK nano fertilizers.
