Abstract:
One of these is maize (Zea mays L.) is major components of hybrid has a greater grain output with Nitrogen. To maximize the output potential of maize, it's crucial to use better cultivars and nitrogen (N) fertilizer. which can adapt to a variety of Agroclimatic conditions, is one of the most adaptable crops. Because of the highest potential-yield of any cereal and referred as the "queen among cereals" internationally. Since maize is a heavy feeder and needs enough nutrients to achieve greater yields, nutrient management is essential for maize production. The use of fertilizers and other soil amendments is maximized with the aid of proper nutrient management, which also increases soil fertility and prevents nutrient deficits and toxicities. A field study entitled “Evaluation of different levels of Nitrogen applied in various number of split doses on growth, yield, and protein content of spring maize (Zea mays L.)” during the Lenten season in 2022 at Lovely Professional University, Punjab. The experiment comprised with 3 N levels (N₉₅, N₁₂₅, N₁₅₅ kg ha¹⁾ and 2 split doses (First irrigation+ Pre-Tasseling), 3 split doses (Sowing + Knee Height + Pre-Tasseling) and 4 split doses (Sowing+ First Irrigation+ Knee Height+ Pre-Tasseling) with 3 replications in (RBD) various N levels significantly affected the grain yield & plant height of maize. N levels and splits significantly affected the grain yield. There was an increase in grain yield with N₁₅₅ kg ha¹ with Four split doses (Sowing+ First Irrigation+ Knee Height+ Pre-Tasseling) as compared to control, N₉₅, N₁₂₅. Whereas application of N₁₅₅ kg N ha¹ results in a significant increase in straw-yield.
