Performance of different arrowroot (Maranta arundinacea L.) genotypes for growth, yield and quality attributes

The study was conducted at RHREC, Dharwad during 2021-2022 with seven genotypes of arrowroot to assess their performance for growth, yield and quality attributes. Plant height ranged from 103.97 cm (TAr-18-5) to 119.54 cm (TAr-18-10) with mean of 109.45 cm. Number of tillers per plant ranged from 6.21 (TAr-18-5) to 9.15 (TAr-18- 10) with a mean of 7.71. Maximum number of leaves were observed in the genotypes TAr-18-10 (56) and minimum in genotypes TAr-18-5 (38.78). The mean of number of rhizomes per plant was 10.93. Maximum number of rhizomes per plant was observed in TAr-18-10 (12.66) whereas minimum was recorded in TAr-18-5 (9.66). Estimated rhizome yield per hectare in arrowroot genotypes ranged from 20.87 tons (TAr-18-5) to 30.72 tons (TAr-18-10) with an average of 27.14 tons. The dry matter content of arrowroot genotypes ranged from 73.09 per cent (TAr-18-4) to 78.77 per cent (TAr-18-3). The total starch content of arrowroot genotypes ranged from 14.33 per cent (TAr-18-3) to 18.39 per cent (TAr-18-5). The carbohydrate content of arrowroot genotypes ranged from 30.44 per cent (TAr-18-12) to 32.56 per cent (TAr-18-4). The crude protein content of arrowroot genotypes ranged from 3.58 per cent (TAr-18-2) to 4.37 per cent (TAr-18-1).
