| Abstract | ||
| To evaluate the effect of nitrogen fertilization levels combined with some micronutrients (Fe, Zn, Mn, Cu, B, N and amino acids) on rice of Sakha 108 cultivar performance, the experiment was conducted in randomized completely block design with 7 treatments. T1 (Control = without fertilization),T2 (recommended fertilizer 69kg N /Fed),T3 (spray with micronutrients Fe, Zn ,Mn, Cu, B, N and amino acids) , T4 (23kg N/fed), T5 (23kg N/fed + Fe, Zn ,Mn, Cu, B, N and amino acids) ,T6 (46kg N/fed) and T7 (46kg N/fed+ Fe, Zn ,Mn, Cu, B, N and amino acids) with 4 replications. The experiment was conducted at the Sakha Agricultures Res. Station Kafr El-Sheikh Governorate, Egypt, over two consecutive seasons (2021and 2022). The results indicated that growth characteristics such as total chlorophyll content, flag leaf area (cm2), plant height (cm) and tillers per square meter were significantly increased with application T2 followed by T7 without significant differences between them in both seasons of study. Also grain yield t/fed and its attributes (panicles/ m2, no of filled grains/panicle, panicle length, panicle weight, 1000 grain weight, grain yield t/fed, straw yield t/fed and harvest index were significantly increased with application T2 followed by T7 without a significant differences between them in both seasons of study except No. of unfilled grains per panicle which increased with T1 (control). Also, T1(control) recorded the lowest values of most studied growth characters and grain yield and its components in both seasons. | ||
