Effects of Different Irrigation Levels with Bio-stimulant Applications on Plant Growth in ‘Kabarla’ Strawberry Variety

Abstract

In this study, the effects of different irrigation levels with bio-stimulant applications on leaf area, crown diameter, number of crown, leaf number and plant width were investigated in a variety of Kabarla. The trail was implemented as a 4×2 factorial scheme (irrigation levels and bio-stimulant use), in split plot design with 6 consequent months at 4 replicates, totaling 32 plots. Bio-stimulant applications were designed as main plot and different irrigation levels were arranged as sub plot. Strawberry plant was subjected to four irrigation water levels (Ir125, 1.25 Ep; Ir100, 1.0 Ep; Ir75, 0.75 Ep; Ir50, 0.50 Ep). Bio-stimulant applications were investigated on morphological parameters with compared by control plot. As a result of the experiment, irrigation levels and growing period influenced the leaf area, crown diameter, plant width, number of crown and leaf number. Bio-stimulant application just positively affected the number of leaf, while other parameters were not affected by the application. All examined parameters were taken same statistical group except of IR50 which negatively affected plant growth. Also as expected, all plant vegetative part increased with time and this increase was determined statistically significant among months. As a result of these data, IR75 irrigation level could be recommended in terms of optimal vegetative growing combined with bio-stimulant applications.
