Effect of organic and inorganic sources of nutrients on growth and yield of turmeric (Curcuma longa L.)

A field experiment was conducted during rainy-cum-winter seasons of 2009-10 and 2010-11 to study the effect of organic and inorganic sources of nutrients on growth and yield of turmeric var. PCT-8. Amongst the applied organic sources of nutrients, farm yard manure (FYM) @ 10 t/ha resulted in maximum growth, yield attributes, yield and net income. The maximum fresh yield of rhizomes was 103.81 q/ha with additional net income (Rs. 23600/ha) over control. Application of 100% recommended inorganic sources of nutrients (N180P60K120) yielded 101.82 q/ha with additional net income (Rs.10300/ha) over control. Thus, FYM was found most remunerative under the existing agro-climatic conditions of Vindhya region of Madhya Pradesh.
