Effect of organic and inorganic nutrient on growth, yield and profitability of turmeric (Curcuma Longa L.)

A field experiment was conducted during 2011–12 and 2012–13 at HRC of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. To investigate the effect of different organic and inorganic nutrients on growth, yield and economics of turmeric cultivation. The experiment was laid out in Randomized Block Design with ten treatments combination and three replications. Application of different combinations of organic and inorganic nutrientsinfluenced the growth and yield of turmeric variety AZAD HALDI-1. The results revealed that the combined applications of 125% NPK (188: 75: 135 kg ha-1)i.e. T6 increased plant height, number of leaves/plant, number of shoot/Plant, weight of rhizome and dry yield of rhizome. While minimum of these were observed in the absolute control i.e. T1. Highest rhizome yield (11.54 &12.15 t ha-1) with maximumbenefit-cost ratio (3.5 & 3.8) was obtained in the treatment combination T6 and the lowest yield (5.75 & 5.93 t ha-1) was obtained in thetreatment T1with minimum benefit-cost ratio (1.4 &1.5).
