Effect of organic formulations on growth and yield of Indian noni (Morinda citrifolia L.) under southern transitional zones of Karnataka

Abstract

The experiment was conducted in five years old noni plot in Raminakoppa village, Shivamogga taluk under the Department of Horticulture, College of Agriculture, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Shivamogga, during 2022-2023 to study the effect of Organic Formulations on Growth and Yield of Indian Noni (Marinda citrifolia L.) under Southern Transitional Zone of Karnataka. The experiment was laid out in RCBD with 11 treatment combinations, comprising of organic manures, biofertilizers and organic liquid formulations with 3 replications. The results revealed that the noni plants received 60:30:30 g NPK/plant recorded maximum plant height (3.52 m), plant girth (41.49 cm), canopy spread (4.86 m2), leaf length (27.70 cm), leaf breadth (12.88 cm), leaf thickness (0.46 mm), leaf area (83873.33 cm2), leaf area index (0.65) and also registered maximum yield parameters such as highest number of fruits (438.24), maximum fruit weight (165.38 gm), fruit yield (72.55 kg/plant) and (56.04 ton/ha) followed by T8 (54.68 ton/ha). Maximum gross return (Rs. 13, 65, 500 ha-1), net return (Rs. 11, 13, 747 ha-1) and benefit cost ratio (4.42) were reported in treatment T8.
