Evaluation of coconut hybrids for tender nut water quality under central dry zone of Karnataka

Abstract

Investigations was carried out at Horticulture Research and Extension Station, Arsikere, University of Horticultural Sciences, Bagalkot during 2018-2019 to identify superior coconut hybrid for nut water. The volume of nut water content and qualitative attributes viz., pH, TSS, total sugars, sugars and mineral contents were analysed. The maximum amount of nut water content (306.67 ml/nut) and the maximum qualitative characters such as TSS (5.77 ˚Brix), pH (5.35), calcium (60.33 mg/100 ml), magnesium (19.17 mg/100 ml), lowest to optimum level of sodium and potassium content (24.80 and 1771.05 ppm) and organoleptic score for colour, taste and overall acceptability (8.23, 8.27 and 8.25, respectively) was recorded highest in Abhaya Ganga. Kalpa Ganga recorded highest values for total (3.77 g/100 ml) and reducing sugar (2.01 g/100 ml), protein (1.11 %), phosphorous (55.10 mg/100 ml) and lowest titrable acidity (0.052%). Hence, hybrid GBGD x LCOT can be utilized for tender nut water purpose followed by GBGD x FJT.
