dc.description.abstractAgricultural production continues to heavily utilize reactive nitrogen from inorganic fertilizers, despite the degrading effects they cause to the environment. Recently, Nitrogen pollution has been highlighted as one of the global challenges that need to be addressed and thus necessities reduction and finding alternative fertilizer sources. This experiment was laid in randomized potted blocks to examine the effects of BIO-FER Natur extra (fermented chicken manure) - FCM and Péti mészsó+ YaraMila Crop Care (calcium ammonium nitrate) - CAN fertilizer on five maize genotypes (ZHY1797ID, ZUY7469OY, 3278IMP, Strong star, and NOAFI) to monitor the nitrogen utilization efficiency at the vegetative growth stage, on biomass production and partitions, residual effects of nutrient sources on the chemical characteristics of soil, and the maximum yield of photosynthesis (Fv/Fm) in a greenhouse model for a period of 8 weeks. 60% minimum water capacity and uniform rate of nitrogen from CAN and FCM (30kg N/Ha) application at first split were used respectively. The highest wet biomass was achieved by using CAN (9301.4 kg/ha), followed by FCM (6900.7 kg/Ha) and the control (5546.1 kg/Ha). The overall N uptake was higher in genotype (ZUY7469OY) in all treatments as compared to other genotypes suggesting higher N utilization efficiency than other varieties and the use of FCM retained a high amount of NO3-N in the soil enhancing soil fertility. The heat tolerant genotypes were (ZUY7469OY), (3278IMP), and (ZHY1797ID) which exhibited higher Fv/Fm with more biomass partitions (Height and root length) compared to the other two genotypes, suggesting a major role of plant genetics in physiological nutrient utilization and food production. Thus, Biomass production and Fv/Fm can provide an early indication of nitrogen utilization efficiency and that the response of maize to nitrogen was different due to the source of Nitrogen. Genotypes with low physiological nutrient utilization efficiency should be avoided by farmers to maximize their profits and protect the environment.
