Response Growth and Yield Traits of Faba Bean Genotype to Foliar Feeding with Triplex Amino Biostimulator

Abstract

A field experiment was carried out in the winter season 2019-2020, in the Nuaimiya region of Fallujah city – Al -Anbar Governorate. The aim of the experiment was to study the response of growth and yield traits of faba bean to foliar feeding with Triplex amino biostimulator. The experiment was applied by using a randomized complete block design (RCBD) according to the arrangement of the split-plot with three replicates. The main plots included three genotypes from the remnants (American, Dutch and Italian), While the sub plots included four concentrations of Triplex amino biostimulator (0, 2.5, 5 and 7.5) g L−1. The Dutch genotype recorded the highest average for each of the number of branches in the plant (8. 84branch.plant−1), leaf area (3289.2 cm2). Plant−1, number of pods per plant (19.25 pods. Plant−1), number of seeds per pod (4.56 seed.pod−1) and seed yield (4.263t.h−1), While the American genotype gave the highest average for plant height (106.70 cm) and 100 seed weight (114.5 g.) The biostimulant significantly effect on all growth and yield traits, the concentration 7.5 g. L−1 gave the highest average for each of Plant height (113.29 cm), number of branches per plant (9.88 branch. plant−1 ), leaf area(3637.9 cm2). Plant−1, number of pods per plant (22.06) pods, number of seeds per pod (4.48 seed.pod−1, weight of 100 seeds (125.2g) and seed yield (4,342 t.h−1). The interaction between the Dutch genotype and concentration 7.5 g. L−1 of the bio stimulant was given the highest average for the number of branches per plant, leaf area, number of pods per plant, and number of seeds per pod.
