Abstract
The field experiment was carried out at the Abu Ghraib Agricultural Research Station Iraq (AGARSI), affiliated with the Agricultural Research body-Ministry of Agricultural of Iraq, to study the spraying with nano fertilizers and the stages of the yield and yield components of varieties of Sorghum. The experiment was designed as a spilled-spilled-plot according to the (RCBD) of three replicates. The main plots involved three varieties of Sorghum (Rabih, Lilo, and Inqath). In contrast, the subplots involved spraying the nano-fertilizers (Nano-Iron and Nano-Zinc) and the control treatment (distilled water). The sub-sub-plots involved the spray stages (Spraying at emerging five leaves, spraying at emerging the last folded leaf, and spraying at 50% flowering stage). The results showed that there were significant differences in all traits, where the variety Inqath had the highest was superior in panicle weight (g), the number of grains per panicle, (CGR)(gm-2.day-1), and grain yield (tons.ha-1). Nano iron was also superior in four traits, panicle weight (g), the number of grains per panicle (CGR)(g.m-2.day-1), and grain yield (tons.ha-1). For the spray stage, the stage of the emergence of five true leaves (S1) was significantly superior in the traits of panicle weight (g), the number of grains per panicle, (CGR)(g.m-2.day-1), and grain yield (tons.ha-1). Keywords: Nano fertilizers; Nano-Iron; Nano-Zinc; grain yield.
