The study was undertaken to improve the growth and biochemical contents in an instant available form through foliar combination of spirulina, soybean and vermiwash. 15, 30 and 45 µg mL-1 concentrations of bio-foliar were sprayed on five different mulberry varieties namely S-1, S-146, S-1635, BR-2 and AR-14 to know their performance on growth parameters and biochemical constituents. Results of the investigation revealed that, among all experimental concentrations mulberry varieties and treatments, BR-2 and S-1635 varieties were performed well in respect of growth parameters and biochemical constituents. Highest leaf area (234.07 cm2) and total leaf yield per hectare (51.48 tons) was noticed in BR-2 mulberry variety at 45 µg mL-1 followed by S-1635 variety. Further highest protein (0.555 mg g-1), carbohydrate (0.668 mg g-1), carotenoids (0.550 mg g-1), total chlorophyll (2.04 mg g-1) and crude protein content (26.67%) were recorded at 45 µg mL-1 concentration by BR-2 variety followed with S-1635 variety as compare to control. The outcome of research implies that, among five mulberry varieties and concentrations, BR-2 and S-1635 varieties with 45 µg mL-1 concentration performed well and successfully augments the productivity and biochemical constituents of different mulberry varieties without any side effect.
