Response of three broad bean varieties ( Vicia faba L.) to boron, iron, and zinc nano fertilizers

This work was carried out at the Research Station of Seed Technology Center Agricultural Department / Ministry Science and during season 2020-2021 to investigate effect three nano fertilizers ( boron, iron, zinc) a rate 2 mg. l-1 on wide been varieties (Syrian, Spanish, Taqa). The experiment in randomized complete block design (R. C. B. D.) with replicates. results showed that Syrian variety gave highest values plant height number pods per plant, while Spanish type pod length, seeds seed weight plant. Taqa recorded branches, total yield 100 seeds, lowest days 50% flowering first formation. Nano increased some growth properties. B-nano fertilizer length pod, Zn- height, yield. Keywords: broad been, pods, yield, fertilizers.
