EFFICACY OF BIO-FOLIAR SPRAY ON GROWTH AND BIOCHEMICAL PARAMETERS OF DIFFERENT MULBERRY VARIETIES

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.
