A field experiment was conducted during the winter season for the years 2018-2019 and 2019-2020 successively to study the effect of foliar application of zinc and boron on growth traits, yield components and quality of three flax genotypes (Lithuania, Ariana and Linot).
The experiment included three concentrations of zinc (0,5 and 10 mg zinc/L) and three concentrations of boron (0, 6 and 12 mg boron/L) implemented according to the factorial experiment in a Completely Random Block Design.
The main findings could be summarized as follows:-
The results indicate that the Lenot genotype gave the highest values ​​for the traits of plant height, stem diameter, number of fruiting branches, number of capsules/plant, number of seeds/capsule, weight of thousand seeds, total seed yield (tons/ha) and oil yield (tons/ha). for seasons 2018-2019 and 2019-2020 respectively.
Foliar application with zinc on plant leaves at a concentration of 5 mg zinc/liter led to a significant increase in plant height, number of fruiting branches, number of capsules/plant, number of seeds/capsule, weight of thousand seeds, total seed yield (tons/ha), oil yield (tons/ha) in both growing seasons.
Adding boron application on plant leaves at a concentration of 6 mg boron/liter led to a significant increase in plant height, stem diameter, number of fruiting branches, number of capsules/plant, number of seeds/capsule, weight of thousand seeds, total seed yield (tons/ha) and oil yield (tons/ha) for seasons 2018-2019 and 2019-2020, respectively.
In general, it can be concluded that the highest total yield of seeds per unit area can be achieved by planting Lenot genotype and adding zinc on plant leaves at a concentration of 5 mg/L and boron at a concentration of 6 mg/L with in Dryland Conditions of this study.
