Coconut inflorescence sap or neera is a sweet translucent juice extracted from unopened inflorescence of coconut, which is oyster white in colour with high nutritive value. Studies revealed that sap yield and quality differed with respect to coconut genotypes and season. Hence a study was carried out to find out the influence of genotypes and season on coconut inflorescence sap yield and quality. The results revealed that the coconut genotypes varied significantly with respect to yield of coconut inflorescence sap. Among the genotypes Jamaica Tall had the highest inflorescence sap yield of 3.6 L/day followed by Orissa Tall (3.05 L/day). Among the seasons, highest sap yield was recorded during post-monsoon (Oct-Nov) and monsoon (June-Sep) and lowest yield was recorded during winter season (Dec-Feb) in all the genotypes. The quality of inflorescence sap tapped from different accessions varied significantly with respect to TSS, total sugars, reducing sugar, phenol, amino acid, ascorbic acid and protein content. Highest TSS (16.9ºBrix), reducing sugar (0.88 g/100ml), amino acid (0.35 g/100ml) and nutrients viz., zinc (0.023 mg/100ml) and copper content (0.056 mg/100ml) was recorded in Jamaica Tall. Highest total sugar (14.57 g/100ml) and phenol (4.14 mg/100ml) were observed in NiuQuewen Tall. Higher protein content of 0.42g/100ml was associated with sap from Benaulim and highest ascorbic acid content was recorded in Gangapani (1.87 g/100ml). Among the season, winter season recorded highest quality parameters in all the varieties. The results obtained from the present investigation indicated that there was a significant influence of genotypes and seasons on inflorescence sap yield and quality parameters.
