ABSTRACT
An experiment was carried out to know the influence of high density planting and fertigation of post-harvest analysis of freshly harvested banana fruits. The post-harvest chemical treatments significantly influenced the physical parameters of banana fruits. The lowest physiological loss in weight (PLW) (2.41%), spoilage (9.62 %), pulp to peel ratio (1.57), slowest colour change (1.62), highest firmness (3.57 kg/cm2) and shelf-life (28.19 days) was recorded in T6 (1-mcp 100 ppb+poly cover), which was followed by T4 (1-mcp 75 ppb+poly cover). However, the lowest (9.02 days) shelf-life was registered in T11 (control), which was on par with T10 (10.10 days) untreated with poly cover. The best flavour (3.68), fruit appearance (2.28), fruit taste (2.34) and over all acceptability (2.50) was recorded in T6 (1-mcp 100 ppb+pc), which was followed by T4 and T8 (GA3 150 ppm + poly cover) treatments. The poor acceptability (1.07) was registered in untreated fruits (Control). The fruit treated with 1-mcp, GA3 and packed in polythene cover gave appreciable over all acceptability compared to other treatments. The total soluble solids, titrable acidity, sugar content steadily increased during the storage period up to ripening stage and later on decreased towards end of shelf-life. The lowest TSS (9.64 0Brix), titrable acidity (0.33 per cent), reducing sugars (5.24 %), non-reducing sugars (2.81 %) and total sugars (8.09 %) was recorded in T6 and highest values were registered in T11 (Control). During the storage period, the ascorbic acid (AA) content decreased steadily up to the end of self-life in all treatments.
