Responses of organic manures and inorganic fertilizers on growth, yield and economics of turmeric (Curcuma longa Linn.)

Experiment was carried out at the College of Horticulture, R.V.S.K.V.V., Mandsaur, M.P. during 2019-2020 in RBD design with three replications. All the parameters significantly influenced with the application of organic manures and inorganic fertilizers. However, the maximum leaf area (520.91, 790.35, 919.20, 1314.28 and 859.98 cm plant-1), LAI (0.583, 0.733, 0.966 and 0.966), LAD (19668.90, 24743.20, 32602.15 and 32613.90 cm2 day-1) were registered under in RDF 50% + VC 100% at different growth stages, CRG in RDF 50% + VC 100% (0.00185) at 60-90 DAS, in RDF 75% + VC 75% (0.00204) at 90-120 DAS, in RDF 100% + FYM 50% (0.00238) at 120-150 DAS and in FYM 25% + VC 25% + NC 25% (0.00253) at 150 DAS - at harvest. Wherever, the maximum RGR in RDF 100% + NC 50% (0.0776) at 60-90 DAS, in RDF 75% + VC 75% (0.0187) (0.0279) at 90-120 DAS and at 120-150 DAS, FYM 25% + VC 25% + NC 25% (0.01804) at 150-at harvest. However, RDF 50% + VC 100% was registered the highest fresh rhizomes yield (332.237 g plant-1) and chlorophyll content (72.83). The highest net return (Rs. 431546.00) and benefit: cost ratio (4.31:1) was obtained from RDF 50% + VC 100%. All the weather data were shown significant sign with most of the parameters, resulted in a better physiological functioning which contributed to higher growth and yield in turmeric.
