Abstract
An investigation was carried out at Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam to find out the effect of various irrigation regimes and manurial treatments on soil and leaf nutrient status of noni (Morinda citrifolia L.). The experiment was carried out in split plot design with irrigation regimes on main plot and manurial treatments on sub plot. Among the treatment combination, M2S7 (100% WRc through drip irrigation + 100% recommended dose of NPK through inorganic fertilizers) showed the highest soil available nitrogen, phosphorus and potassium content. The same treatment combination recorded the increased leaf nitrogen, phosphorus and potassium content during vegetative, flowering and harvesting stages.
Key words: Morinda citrifolia L., drip irrigation, check basin method of irrigation, farmyard manure, vermicompost, coir pith compost, inorganic fertilizers, soil nutrient status, leaf nutrient status.
