Effect of inorganic and organic fertilizers on growth, yield and nutrient uptake in beetroot (Beta vulgaris L.) under shade-net conditions

Abstract

An experiment was conducted to find the effect of inorganic and organic fertilizers application on growth, yield and nutrient uptake of beetroot (Beta vulgaris L.) under shade net condition. Fertigation with water soluble fertilizers at 100 % RDF along with liquid phosphobacteria and vermicompost treatment (T7) showed the best performance in almost all the parameters studied in both the crops (I and II) with the highest mean plant height (16.76, 45.50 and 43.22 cm), leaf area (260.23, 1929.95 and 1101.46 cm2) and dry matter production (419.40, 2008.17 and 2338.62 kg ha-1) on 30, 60 and 90 DAS. The highest uptake of NPK also recorded in T7 treatment with the highest mean nitrogen (11.60, 61.90 and 76.76 kg ha-1), phosphorus (1.36, 7.21 and 12.75 kg ha-1) and potassium uptake (11.60, 55.30 and 69.27 kg ha-1) on 30, 60 and 90 DAS. Highest yield hectare-1 was also observed in the same treatment with the value of 37.97 and 34.52 t ha-1 in crop I and II, respectively.
