Response of various level of nitrogen and plant spacing on yield and yield attributing characters of turmeric (Curcuma longa L.) at farmers field of Azamgarh, (Uttar Pradesh)

A field experiment cum demonstration was conducted at farmers field in village Bhelkhara during the year 2008–09 and 2009–10 to find out the optimum dose of nitrogen and spacing on yield characters of turmeric cv. Medukar in sandy loam soil. Treatment consisted of four levels each of nitrogen and plant spacing along with control. Application of 100 kg nitrogen per hectare along with wider plant spacing 45x45 cm significantly increased the yield of fresh rhizome, number of finger per plant, length and width of finger and weight of fingers per plant in both the years of experimentation. Yield of fingers was affected significantly under the various plant spacing. The close plant spacing of 45x45 cm at 100 kg nitrogen level per hectare. Thus, it is clear that increasing plant density decreased the yield of fingers significantly but total yield per hectare were increased.
