Effect
No effect on produce quality
No effect on water use efficiency
Kelpak treated raspberries subjected to different fertigation regimes in commercial set up showed no sig. differences in yield, BRIX, stomatal conductance (LiCOR), chlorophyl fluorescence (MiniPAM), xylem pressure, fruit/biomass fresh and dry weight, water use efficiency (C13 isotope analysis ) or nutrient use efficiency (C:N ratio) when compared to the control plants grown at the same conditions.
