Growth, yield and fruit quality of noni (Morinda citrifolia L) as influenced by integrated nutrient management under mixed cropping in coconut garden

An experiment was carried out on noni (Morinda citrifolia L) grown as a mixed crop in a coconut garden to study the effect of integrated nutrient management (INM) practices on growth, yield and fruit quality of the former. The study revealed that the adoption of INM practices with organic manure, in situ green manure, biofertilizers and inorganic fertilizers was more effective in improving growth, yield and fruit quality of noni as compared to application of inorganic fertilizers alone. The treatment combinations of 75 per cent recommended dose of fertilizers (RDF) from inorganic sources + 25 per cent RDF from organic sources resulted in significant increase in plant height (32.9%). Application of nutrients 50 per cent from inorganic and 50 per cent from organic sources resulted in maximum fruit weight (34.24 g), fruit length (6.4 cm), yield (87.59 q/ha), total soluble solids (10.72°Brix) and minimum acidity (0.24%) of matured fruits.
