Effect of Different Spacing and Nitrogen Levels on of Beetroot cv. Detroit Dark Red Quality Parameters under Telangana State Conditions

Abstract

The aim of this paper was to establish the effect of different spacing and nitrogen levels on quality parameters of beetroot cv. Detroit Dark Red under Telangana state conditions. It was carried out during rabi season of 2020-21 at SKLTSHU, College of Horticulture, Rajendranagar, Hyderabad, India. The experiment was laid out in Factorial Randomized Block Design 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 effects of the spacing and nitrogen levels was observed for quality characters. Highest total soluble solids (TSS) (9.93 oBrix), reducing sugars (1.64%), total sugars (7.31%) and chlorophyll content 45.50 (SPAD value) were recorded in wider spacing S1- 45 cm x 15 cm and highest ascorbic acid content (10.09 mg 100g-1) was recorded in closer spacing S4-15 cm x 15 cm, whereas pH and titrable acidity were found to be non-significant. Highest pH (6.20), reducing sugars (1.52%), total sugars (7.29%), ascorbic acid content (10.06 mg 100g-1) were recorded in nitrogen level N1-70 Kg N ha-1, whereas highest TSS (9.79 oBrix), chlorophyll content 45.70 (SPAD value) were observed in nitrogen level N4-122.5 Kg N ha-1. The interaction effect on quality parameters was found to be non-significant.
