Current study was carried out in the Department of Horticulture and Forestry, Directorate General for Agriculture in Najaf province, during 2021 spring season to determine the response of growth and yield of (Capsicum annuum L.) to the spraying with nano-amino acids and potassium silicate. 12 treatments including four concentrations of nano-amino acids as a foliar feed (0.0, 0.5, 1.0 and 1.5ml.L-1) and three concentrations of potassium silicate (0, 2 and 4ml.L-1) were applied by spraying these concentrations of the vegetative growth of sweet pepper cv. California Wonder. A factorial experiment was arranged using randomized complete blocks design (RCBD) with three replicates and the ANOVA analysis was done using least significant difference test (L.S.D.) at 5% level of significance (P>0.05). Results showed that treatment of spraying 1.5ml.L-1 of Nano amino acids was exceled other treatment of foliar spraying in all studied traits, and gave the highest average of growth, yield including plant height, total number of leaves, leaf area, dry weight of total vegetative, dry weight of root, fruits number, the yield of a single plant and total yield. The treatment of spraying 4ml.L-1of potassium silicate was significantly exceled other concentrations and gave the highest increasing in vegetative and quantitative indicators.
