Effect of Shade Net Colours, Its Intensity and Fertilizer Levels on Growth and Yield of Beetroot (Beta vulgaris L.)

The effect of shade net colours, its intensity and fertilizer levels on some growth parameters viz. plant spread, leaf area, biomass yield and beetroot yield indicated that red shade net colour significantly increased beetroot yield (28.02 t ha-1) as compared to green (25.23 t ha-1) and black (21.87 t ha-1) however, leaf area plant-1 at 30, 45, 60 DAS and at harvest were 9.87, 18.63, 29.36 and 38.56 dm2, respectively. shade net colours, suggesting suitability of the red shade net colour for beetroot cultivation. The 35 per cent shading intensity significantly increased beetroot yield (29.32 t ha-1) as compared to 50 (26.22 t ha-1) and 75 per cent (19.57 t ha-1) and plant spread at 30, 45, 60 DAS and at harvest were 28.40, 40.13, 51.99 and 57.46 cm, respectively. The significantly higher beetroot yield was recorded in 125 per cent RDF (26.00 t ha-1) than 100 per cent RDF (24.08 t ha-1).
