Abstract

An experiment was conducted in Morinda citrifolia to find out the suitable water regime along with organic manure schedule for obtaining superior quality fruits. The experiment was carried out in split plot design with irrigation regimes on main plot (four levels) and organic manures on sub plot (eight levels) with two replications. Among the interaction, M₂S₄ (100% crop water requirement through drip irrigation + 50% farmyard manure + 50% vermicompost) recorded the highest scores for pulp recovery (47.12%), juice recovery (34.32%), TSS (11.26^o brix), ascorbic acid (197.82 mg/100 g), titrable acidity (0.392%), fruit firmness (3.26 kg/cm²), total carbohydrate (584.39 mg/100 g), total phenol (374.26 mg/100 g), total carotenoids (0.177 mg/100 g), protein (412.95 mg/100 g) and total flavonoids (128.53 mg/100 g) content of noni fruits.

Key words: Morinda citrifolia, drip irrigation, farmyard manure (FYM), vermicompost, quality, carotenoids, flavonoids, protein.
