Abstract:

Nitrogen is the essential nutrient that plays a vital role for protein synthesis, cell multiplication and differentiation. Nitrogen makes up approximately 1-4% of the dry matter and plays a crucial role in facilitating the movement of stored photosynthetic products and the absorption of other vital nutrient. The experiment was carried out at Agronomy Student field Department Sindh Agriculture University during 2022 autumn session. An experiment was laid out in Randomized Complete Block Design (RCBD) to determine the influence of different nitrogen levels on maize growth and seed yield. The experiment consists of four treatments of N levels repeated three times. The treatments include were, N1 = 00 kg ha-1, N2 = 108 kg ha-1, N3 = 120 kg ha-1, N4 = 132 kg ha-1. The analysis of variance (ANOVA) showed significant difference (P<0.05) for all growth and yield characteristics due to treatments, tallest plant (178.9 cm), maximum stem girth (12.5 cm), maximum number of internodes (13.5 plant-1), maximum days taken to seedling emergence (7.6), maximum days taken to tasseling (66.6), maximum biological yield (13749.7 kg ha-1) and maximum grain yield (4025.0 kg ha-1) were recorded in treatment providing 132 kg N per Ha and lowest growth was in control (N1, no fertilizer) smallest plant (149.8 cm), minimum stem girth (9.7 cm), minimum number of internodes (10.8 plant-1), minimum days taken to seedling emergence ((10.2), minimum days taken to tasseling (69.4), minimum biological yield (6249.7 kg ha-1) and minimum grain yield (1952.3 kg ha-1.It is concluded that maize performed better at treatment, T4 - provided with N = 132 kg per Ha.
