Abstract:
The present investigation entitled “Studies on effect of different spacing and nitrogen levels on growth and yield of beetroot (Beta vulgaris L.) cv. Detroit Dark Red under Telangana conditions” was carried out during rabi season of 2020-21 at SKLTSHU, College of Horticulture, Rajendranagar, Hyderabad. The experiment was laid out in Factorial Randomized Block Design (FRBD) with sixteen treatments replicated thrice. Treatment consisted of four levels of spacing S1 (45cm ×15cm), S2 (30cm×15cm), S3 (30cm×10cm) and S4 (15cm ×15cm) and four levels of nitrogen N1 (70 Kg ha-1), N2 (87.5 Kg ha-1), N3 (105 Kg ha-1) and N4 (122.5 Kg ha-1). The significant effect of the spacing and nitrogen levels were observed for growth and yield characters. Growth characters like plant height recorded highest in spacing level S4 (15cm ×15cm) and number of leaves per plant was found maximum in spacing level S1 (45cm ×15cm) and plant height and number of leaves per plant at 25, 50 and 75 DAS were recorded maximum in nitrogen level N4 (122.5 Kg ha-1). Yield characters like root length, root girth and weight of root per plant were observed maximum with spacing level S1 (45cm×15cm) and yield characters like length of root, girth of root and weight of root per plant were observed maximum with nitrogen level N4 (122.5 Kg ha-1). The yield per plot and yield per ha (45.89 t) were observed maximum with spacing level S4 (15cm×15cm) and yield per plot and yield per ha (40.44 t) were observed maximum with nitrogen level N4 (122.5 Kg ha-1).
