Abstract

A study on wheat's response to varying seed rates (60-150 kg/ha) and nitrogen levels (0-160 kg/ha) revealed significant effects on yield attributes. Nitrogen application at 120-160 kg/ha improved tillers/m² (436, 394), thousand grain weight (42, 41g), spikes/m² (381, 362). Seed rates of 120-150 kg/ha enhanced emergence/m² (124, 132), tillers/m² (398, 338), and spikes/m² (382, 413). The interaction between nitrogen and seed rates affected key traits, with optimal results obtained at 120-150 kg/ha seed rate and 120-160 kg/ha nitrogen, yielding tillers/m² (491), spikes length (11.7cm), and spikes/m² (450). Results showed that nitrogen application at 120-160 kg/ha significantly improved yield attributes. Seed rates of 120-150 kg/ha also enhanced yield parameters. The interaction between nitrogen and seed rates affected key traits, with optimal results obtained at 120-150 kg/ha seed rate and 120-160 kg/ha nitrogen.
