The effect of Bactofeed biostimulant and boron spraying on the growth, yield and quality of two okra hybrids

Abstract

The experiment was conducted in the field of the College of Agriculture,
University of Kerbala, during the summer agricultural season of 2024. The
experiment was conducted to determine the effect of eight combined fertilizer
combinations, including the addition of the Bactofeed biostimulant and boron
spraying. The combinations were as follows: (control, 1 g L-1
boron as boric acid
foliar spray, 20 L ha-1 Bactofeed biostimulant, 25 L ha-1 Bactofeed biostimulant, 30
L ha-1 Bactofeed biostimulant, 20 L ha-1 Bactofeed biostimulant with 1 g L-1
boron,
25 L ha-1 Bactofeed biostimulant with 1 g L-1
boron, and 30 L ha-1 Bactofeed
biostimulant with 1 g L-1
boron) on the growth , yield and quality of two okra
hybrids: the hybrid (Sultana F1) and the second hybrid (Gennext). A factorial
experiment was applied with a randomized complete block design (RCBD) with
three replicates, and the means were compared according to the LSD test at a 5%
probability level.
The results showed that the fertilizer treatment (30 L ha-1
biostimulant + 1 g
L
-1
boron) was significantly superior in all studied traits (total chlorophyll
concentration in leaves, percentage of nitrogen, phosphorus and potassium, boron
concentration in leaves, plant height, number of branches, number of leaves, leaf
area, dry weight of the vegetative system, percentage of flower set, number of pods
per plant, average pod weight, yield per plant, total yield, percentage of
carbohydrates, protein and fibers).
The results also showed that the hybrid Gennext significantly outperformed
the hybrid Sultana F1, giving the highest averages for all studied traits.The results also showed a significant effect of the two-way interaction
between the two hybrids and the fertilizer treatments on all studied traits, as the
interaction between the hybrid Gennext and the fertilizer treatment (30 L ha-1
biostimulant + 1 g L-1
boron) was superior in giving the highest average of the
studied traits (total chlorophyll concentration in leaves, percentage of nitrogen,
phosphorus and potassium, boron concentration in leaves, plant height, number of
branches, number of leaves, leaf area, dry weight of the vegetative system,
percentage of flower set, number of pods per plant, average pod weight, yield per
plant, total yield, percentage of carbohydrates, protein and fibers), as the averages
reached (107.30 mg 100 g-1
