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

Abstract

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