Abstract
Two field experiments were carried out during the summer seasons of 2018
and 2019, at the Experimental Farm of Faculty of Agriculture (Saba- Basha) at Abees
area, Alexandria University, Egypt, to study the effect of foliar application of the
various levels of both BA as cytokinin and Boron on vegetative growth, yield, and
quality of ’ Hermes’ potato cultivar.
The treatments were distributed in experimental randomized complete block
design (RCBD) as follows:
Control (sprayed with tap water)
10 mg/l (boron)
20 mg/l (boron)
30 mg/l (boron)
10 mg/l (20 mg/l (cytokinen)
20 mg/l (cytokinen)
30 mg/l (cytokinen)
10 mg/l (boron)+10 mg/l (cytokinen)
10 mg/l (boron)+20 mg/l (cytokinen)
10 mg/l (boron)+30 mg/l (cytokinen)
20 mg/l (boron)+10 mg/l (cytokinen)
20 mg/l (boron)+20 mg/l (cytokinen)
20 mg/l (boron)+30 mg/l (cytokinen)
30 mg/l (boron)+10 mg/l (cytokinen)
30 mg/l (boron)+20 mg/l (cytokinen)
30 mg/l (boron)+30 mg/l (cytokinen)
The obtained results could be summarized as follow:
5.1. Growth characters
Folia application of B-levels significantly affected potato growth parameters
(number . of stems per plant, No. of leaves per plant, plant height, plant fresh and dry
weight) and recorded the highest values with B30 mg.l-1., foliar application of the
highest level of cytokine at 30 mg.l-1 gave the highest mean values of potato growth
parameters during both seasons. The combined treatment between boron at 30 mg/L and cytokinin at 30mg/L, achieved the highest average values of a for mentioned
growth characters, compared to other treatments, in both seasons.
