ABSTRACT
Nitrogen application can play a significant role in improving soil fertility. Fertilization of nitrogen can increase grain yield and biomass in maize. A field experiment was conducted at the Lovely Professional University’s soil in Jalandhar, Punjab to calculate the effect of nitrogen addition on maize growth, yield, nutrient absorption and economics during 2022 and 2023 kharif season using organic and inorganic fertilizer solutions. It was done using a randomized block design including 16 treatments in three replications. The PMH-13 hybrid variety of maize was used in the experiment. Both phosphorus and potassium were completely supplied as basal application. At harvest, the plant height in T12 (100% RDF + vermicompost 2.5 t/ha) treatments gave best performance. Thus, vermicompost was an effective nutrient for maize growth and yield. An important sign of plant growth was plant height in the grain yield of hybrid maize PMH-13 as impacted by the use of nitrogen fertilizer in coarse loamy soils of Punjab, as well as by different nitrogen doses.
Key words: Maize, nitrogen, maize yield
