The Effect of Chelated Nano Zinc on Growth and Yield of Several Genotypes of Faba Bean Vicia faba L.

Abstract

A field experiment was carried out in the Al-Hussay area in Al-Fallujah district, Anbar Governorate, located at latitude 33°N and longitude 43°E, during the winter growing season of 2021-2022. The experiment aimed to study the effect of two concentrations of chelated zinc nano fertilizer (0.5 and 1 g L−1) in addition to a control treatment sprayed with distilled water only, on the growth, yield, and its components of three genotypes of faba beans Vicia faba L. (local, Turkish, and Spanish). The experiment was conducted using a split-plot arrangement in randomized complete block design (R.C.B.D) with three replications, the number of experimental units was 27 units, and the main plots contained different concentrations of nano zinc fertilizer, and the genotypes occupied the subplots. The statistical analysis showed that the Spanish Genotype Superior in several characteristics, such as plant height, number of branches per plant, chlorophyll content in the leaves, number of seeds per pod, and seed yield (120.8 cm, 12.90 branches per plant, 42.11 SPAD, 6.17 seeds per pod, and 144.17 g plant−1) respectively. While, the Turkish Genotype Superior in the number of pods per plant, 100-seed weight, and biological yield (30.98 pods plant−1, 142.09 g, and 274.44 g plant−1) respectively.
