Response of dry seed yield of faba bean “Vicia Faba, L. ” to spraying with amino acids, organic acids, (NAA)‎ growth regulator and micro nutrients

الملخص EN

Field experiment were carried out at Sakha Horticultural Research Station, Agricultural Research Center, Egypt, during two successive winter seasons of 2017/2018 and 2018/2019 to study the effect of foliar spraying with some stimulate substances i.

e; Green Miracle (G.

M) at the rate of 3cm / L, Mono Potassium Phosphate (MKP) at the rate of 6 gm / L, Naphthalene Acetic Acid (NAA) at the rate of 0.6 gm / L, potassium silicate at the rate of 3cm / L, fulvic acid at the rate of 1 gm / L, Boron (B) at the rate of 1.5 gm / L, Zinc (Zn) at the rate of 1.5 gm / L and (Zinc+ Boron) at the rate of (1.5+1.5) gm / L.

, besides, control spraying with tap water) on growth characters, dry seed yield and its components and chemical analysis of dry seeds of broad bean (Vicia Faba L) cv.

Weaam.

The experiments were arranged in a randomized complete block design with three replications.

Seeds were sown in the 1st week of November during the two seasons.

The results indicated that all foliar spraying treatments increased vegetative growth characteristics, dry seed yield and its components and chemical constituents in dry seeds compared to control.

Where as, foliar spraying with the Green miracle at the rate of cm3/L was among best stimulant substance, since, markedly improved most of the studied characters, i.

e.

vegetative growth characteristics, dry seed yield and its components and chemical constituents in dry seeds.

Treatments led to highly significant increased of all studied parameters followed by foliar spraying with Naphthalene Acetic Acid (NAA) at the rate of 0.6 gm / L and potassium silicate at the rate of 3cm / L.

compared to the other treatments or the control.
