Influence of Nitrogen Fertilization Rates on Growth and Productivity of Maize (Zea mays L.) variety Fezzan under Conditions in the Tazirbo Region
الملخص
A field experiment was conducted during the 2024 summer season at a farm in the Tazirbo region, Libya, to investigate the response of maize (Zea mays L.) variety (Fezzan) to varying levels of nitrogen fertilization. The experiment was laid out in a Randomized Complete Block Design (RCBD). Nitrogen fertilization treatments comprised four levels: 225, 300, 375, and 450 kg N ha⁻¹. Results indicated that the studied traits, including plant height (cm), ear length (cm), number of grains per row, grain weight per ear (g), and 100-grain weight (g), were significantly affected by the nitrogen fertilization rates. The highest grain yield was achieved at the 450 kg N ha⁻¹ application rate, demonstrating the efficacy of this level in enhancing the productivity of the Fezzan maize variety under the environmental conditions of the Tazirbu region.
