EFFECT OF ORGANIC AND INORGANIC MANURIAL COMBINATIONS ON TURMERIC (CURCUMA LONGA L.)

The present experiment was conducted during the year 2011-2012 at Vegetable Research Farm, Department of Horticulture, Sam Higginbotom Institute of Agriculture, Technology and Sciences (SHIATS), Allahabad (U.P.), India; to evaluate the effect of organic and inorganic manurial combinations on turmeric (Curcuma longa L.). The different treatment combinations were- T 0 : full dose of RDF with chemical fertilizers (60 : 50 : 120 kg NPK/ha), T 1 : 75% N through urea + 25% N (Vermicompost), T 2 : 75% N (urea) + 25% N (Poultry manure), T 3 : 75% N (urea) + 25% N (Farmyard manure), T 4 : 50% N (urea) + 50% N (Vermicompost), T 5 : 50% N (urea) + 50% N (Poultry manure), T 6 : 50% N (urea) + 50% N (Farmyard manure), T 7 : 25% N (urea) + 25% N (Vermicompost), T 8 : 25% N (urea) + 25% N (Poultry manure) and T 9 : 25% N (urea) + 25% N (Farmyard manure). The results clearly indicate that the treatment T 5 significantly increased plant height, leaf length, leaf width, leaf area, number of leaves/plant and number of tillers/clump followed by T 4 over the control. The highest fresh rhizome yield (154.18 q/ha), dry rhizome yield (34.73 q/ha) and curcumin content (5.2%) were recorded in the treatment T 5.
