Abstract:
Strawberry is an important crop belonging to the family Rosaceae. We had studied the effect of blue and red-light spectral ratio along with different PAR levels on the growth, quality, and yield of strawberries under the indoor vertical farming unit. We have taken 5 treatment combinations of light with different PAR levels for the experiment. We set up the LED lighting for an indoor farm. The light spectral treatments given to the plants were T₁-Blue light: Red light (1:2.5) with PAR (180-200 (?mol?m^-2s^-1) T₂-Blue light: Red light (1:2.5) with PAR (220-400) ?mol?m^-2s^-1), T₃-Blue light: Red light (1:2) with PAR (240 ?mol?m^-2s^-1), T₄-Blue light: Red light (1:3) with PAR (240 ?mol?m^-2s^-1), T₅ Blue light: Red light (1:5) with PAR (240 ?mol?m^-2s^-1). Among all the treatments T₅ Blue light: Red light (1:5) with PAR (240 ?mol?m^-2s^-1) has shown plant height has recorded the highest plant height (23.37cm), number of leaves (21.75) and number of runners as (8) Reproductive parameters were also highest in treatment T₅ Blue light: Red light (1:5) with PAR (240 ?mol?m^-2s^-1) showing the maximum number of fruits per plant (7), fruit length (4.76), fruit firmness (4.09), total soluble solids (9.6) and yield per plant (20.78).
