Effect of Different Mixed Fertilizer on Some Physiological Traits, Growth and Nutrient Uptake in Beetroot (Beta vulgaris L.)

Beetroot is a widely grown crop in Tamil Nadu and other states in India. In Tamil Nadu, beetroot yield is lower than in other states due to inadequate fertilization. A field experiment was carried out during rabi, 2023 to study the effect different mixed fertilizer on some physiological traits, growth and nutrient uptake in beetroot (Beta vulgaris L.) in acid soils, at woodhouse, Horticulture Research Station, Ooty district. Three replicated eight treatments (T1: N0P0K0, T2: N1P1K2, T3: N1P2K2, T4: N2P2K0, T5: N2P1K1, T6: N3P1K1, T7: N2P3K2, and T8: N3P3K2) were used in the randomized block design experiment. Among the treatments T8 (N3P3K2) is best for growth recorded as minimum number of days required for 80 per cent germination of seedlings (6.00 days), longer plant height (56.2 cm), more number of leaves per plant (21), Leaves breadth (14.5) and higher chlorophyll content index (46.38), with maximum availability of Nitrogen (169.76 kg ha-1), Phosphorous (94.24 kg ha-1), Potassium (110.16 kg ha-1).
