Studies on the Effect of Different Levels of Organic Compost on Growth, Yield, Betalain Content and Quality of Beetroot (Beta vulgaris) under Prayagraj Agro-Climatic Condition

The present investigation entitled “Studies on the effect of different levels of organic compost on growth, yield and betalain content of beetroot (Beta vulgaris) under Prayagraj agro-climatic condition” was carried out during rabi season 2022 at Departmental Field of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj Uttar Pradesh. The experiment was laid out in Randomized Block Resign (RBD) with three replication and 10 treatments. The minimum days taken to germination 7.87, highest plant height 47.03 centimetre, maximum number of leaves 13.53 and highest leaf area 108.99 cm2 was recorded from T4: 50% vermicompost+50% poultry manure. The yield parameters i.e. diameter 6.0 centimetre ,polar length of beetroot 6.8 centimetre, weight of beetroot 126.92 gram and yield 21.93q/hac. was recorded highest among all treatments from T4 followed by T0. The quality parameters i.e. T.S.S 10.910 Brix, chlorophyll content (SPAD value) 68.61 and betalain content 58.46% was recorded highest from T4 among all treatments. The benefit cost ratio among all treatments was highest recorded in T4 2.53 respectively.
